Release Notes

naudio/NAudio (NAudio)

v3.1.0

A correctness release, with Native AOT as the theme. NAudio's remaining
[StructLayout] interop types — WAVEHDR, ACMSTREAMHEADER and WaveFormat
itself — were passed to native code by value, which CoreCLR pins in place but
the AOT marshaller copies into a per-call temporary. Anything the driver or
codec wrote back was silently discarded, so WaveIn/WaveOut, ACM conversion
(and with it Mp3FileReader and AudioFileReader) and every WASAPI, Media
Foundation and DMO format negotiation were broken in an AOT-published app while
building and running cleanly. Those paths now marshal by hand into stable
unmanaged blocks, and NAudio.WinMM joins the AOT-compatible package set.

The two breaking changes below both fall out of that work. Also fixed are two
3.0.0 regressions — Mp3FileReaderBase seeking on files with a Xing/Info
header, and WdlResamplingSampleProvider losing samples when its source
under-feeds — and a pair of infinite loops in the WAV parser on corrupt files.

• Breaking: WaveFormat and its subclasses no longer carry [StructLayout], so Marshal.SizeOf and Marshal.PtrToStructure on them now throw ArgumentException instead of silently returning wrong data under Native AOT (Marshal.SizeOf<WaveFormatExtensible>() returned 22 rather than 40, and a decoded format kept its constructor defaults). NAudio itself stopped marshalling these types in 3.1.0; use ToWaveFormatExBytes, MarshalToPtr or MarshalFromPtr to cross a native boundary (#​1432)
• Breaking: AudioClient.IsFormatSupported and WasapiPlayer.IsFormatSupported now return the closest-match format as out WaveFormat rather than out WaveFormatExtensible. WASAPI documents this format as either a WAVEFORMATEX or a WAVEFORMATEXTENSIBLE, and the old signature could only represent the latter — a plain format was previously decoded as a WaveFormatExtensible whose base fields were valid but whose extensible fields were meaningless. Callers needing the extensible fields should pattern-match (#​1425)
• Fixed WaveIn/WaveOut failing under Native AOT with WaveHeaderUnprepared ("The wave header was not prepared"). The WAVEHDR was a [StructLayout] class passed to winmm by value, which CoreCLR pins in place but NativeAOT copies into a per-call temporary, so the driver's WHDR_PREPARED/WHDR_DONE/dwBytesRecorded writes were discarded. It is now a struct in a stable unmanaged block (#​1425)
• Fixed ACM conversion failing under Native AOT — WaveFormatConversionStream, AcmStream and so Mp3FileReader and AudioFileReader. ACMSTREAMHEADER was a [StructLayout] class passed to msacm32 by value, and the codec keeps private state in the header's reserved fields between acmStreamPrepareHeader, acmStreamConvert and acmStreamUnprepareHeader; the AOT marshaller's per-call copy round-trips only the declared fields, so that state was lost and conversion failed. It is now a struct in a stable unmanaged block, as WAVEHDR already is (#​1425)
• Fixed WaveFormat.MarshalToPtr and WaveFormat.MarshalFromPtr corrupting any WaveFormat subclass under Native AOT — the AOT marshaller drops the inherited WAVEFORMATEX fields of a class hierarchy, so a WaveFormatExtensible was written with its SubFormat GUID over the sample rate. Every remaining site that sized or wrote a WaveFormat with Marshal.SizeOf/StructureToPtr was converted too: WASAPI (AudioClient), Media Foundation (MFInitMediaTypeFromWaveFormatEx, reachable from MediaFoundationResampler/MediaFoundationEncoder), DMO (DmoMediaType.SetWaveFormat, MediaObject) and ACM (AcmStream, AcmDriver) (#​1425)
• WaveFormat.MarshalToPtr now always allocates at least the 18 + cbSize bytes it advertises. A WaveFormat subclass that declares extraSize but doesn't write it in Serialize previously produced a block shorter than its own cbSize, which a native consumer would read past (#​1425)
• Added WaveFormat.ToWaveFormatExBytes(), which renders a WaveFormat as a native WAVEFORMATEX byte array. MarshalToPtr is now a thin wrapper over it, for callers who need an unmanaged block rather than a buffer they already own (#​1425)
• Added a Serialize override to Mp3WaveFormat, which previously advertised cbSize = 12 but wrote none of its 12 MPEGLAYER3WAVEFORMAT extra bytes (#​1425)
• WaveFormatExtraData now sizes its buffer from cbSize instead of holding a fixed 100-byte array, so a fmt chunk declaring more than 100 bytes of extra data keeps it rather than having all of it discarded (#​482). The fixed size existed only because [MarshalAs(ByValArray, SizeConst = 100)] needed a compile-time length. ExtraData is now exactly ExtraSize bytes long rather than always 100 (#​1432)
• NAudio.WinMM is now marked IsAotCompatible, and the AOT smoke test covers the winmm WAVEHDR/WAVEFORMATEX paths (#​1425)
• Fixed Mp3FileReaderBase seeking silently restarting playback from the beginning of the file on MP3s with a Xing/Info header — the lazy frame index was gated on IsLengthExact, which such a header sets without any frame having been scanned. Also fixed seeks landing on the wrong frame when the target fell exactly on a frame boundary, and Xing/Info header frames being indexed as audio (shifting every seek in those files ~26 ms early). A 3.0.0 regression (#​1419)
• Fixed WdlResamplingSampleProvider losing samples, and eventually returning 0 permanently, when asked for more output than the source could supply — a 3.0.0 regression that broke the common pattern of reading generously from a BufferedWaveProvider-backed capture chain. WdlResampler.ResampleOut also no longer drifts in input-driven (feed) mode when handed fewer samples than ResamplePrepare requested (#​1412)
• Fixed two infinite loops in the WAV parser triggered by corrupt files declaring a negative chunk size. An RF64 ds64 chunk with a negative dataChunkLength, or a LIST/adtl sub-chunk with a negative size, made the chunk walk advance by zero bytes per iteration and spin at 100% CPU without throwing. Negative and oversized sizes are now rejected where they are read, and an undersized ds64 chunk throws FormatException rather than ArgumentOutOfRangeException (#​1428)
• Fixed the NAudioConsoleTest WASAPI exclusive-mode quick scan reporting no supported formats at all on devices that support plenty — it built its probe formats with an empty WAVEFORMATEXTENSIBLE channel mask, which drivers such as Realtek reject outright. It now probes with the canonical layout for the channel count, the same mask the library's own format adaptation uses (#​1431)

v3.0.1

A patch release. The headline fix is packaging: the NAudio and NAudio.Extras
meta-packages now ship a plain net9.0-windows leg, so WinForms and WPF projects
targeting netX.0-windows get the full Windows stack again.

• Breaking: AudioFileReader now throws NotSupportedException instead of InvalidOperationException when the cross-platform build is asked for a format it cannot read, and the messages simply state that rather than suggesting an NAudio.Wasapi install that could never have helped (#​1407)
• Fixed the NAudio and NAudio.Extras meta-packages resolving their portable net9.0 asset on projects targeting a plain netX.0-windows TFM (the WinForms/WPF template default), which silently dropped the entire Windows stack — no WaveOut, WASAPI, Media Foundation, ASIO, DMO or WinForms types, and AudioFileReader throwing "MP3 file reading requires the NAudio.Wasapi package". Both packages now also ship a plain net9.0-windows leg (#​1407)
• Projects on a plain netX.0-windows TFM may now see CA1416 warnings when calling WASAPI process-loopback capture. The warning is correct — those callers do need an OperatingSystem.IsWindowsVersionAtLeast(10, 0, 19041) guard — and was previously hidden because the only Windows asset available already implied that floor (#​1407)
• Sample and tool apps now roll forward onto newer .NET runtimes, so running them no longer requires the .NET 9 runtime to be installed (#​1408)
• Fixed AiffFileReader reporting too long a Length and throwing IndexOutOfRangeException when the SSND chunk declares a non-zero offset (#​1405)
• Fixed AiffFileReader.Read throwing IndexOutOfRangeException when the source stream returns fewer bytes than requested (#​1405)

v3.0.0

NAudio 3 is a major release. The single NAudio assembly is now split into
focused, independently usable packages; the minimum target framework moves to
net9.0; the core is cross-platform and Native-AOT compatible; and several
large new subsystems — a cross-platform effects suite, a software sampler, VST 3
hosting, and ALSA and libsndfile backends — join the library.

Upgrading from NAudio 2? Migrating from NAudio 2 to NAudio 3
walks through every breaking change with before/after code. Most apps need only
re-target to net9.0, rename WaveOutEvent to WaveOut, and adjust custom
providers to the new Span<T> Read signature.

Packages and platform

• Minimum target framework is now net9.0 — legacy .NET Framework and .NET Standard 2.0 support is dropped
• NAudio is now a set of focused packages: NAudio.Core, NAudio.Midi, NAudio.WinMM, NAudio.Wasapi, NAudio.Asio, NAudio.Dmo, NAudio.WinForms, plus the new NAudio.Effects (shipped in NAudio.Core), NAudio.Sampler, NAudio.Vst3, NAudio.Alsa and NAudio.SoundFile. The NAudio meta-package still pulls the Windows stack together, so existing consumers see no change. See Docs/Architecture/NAudio3AssemblyLayoutPlan.md
• NAudio.Core, NAudio.Midi, NAudio.Wasapi, NAudio.Dmo, NAudio.Sampler, NAudio.SoundFile and NAudio.Alsa are Native-AOT compatible (IsAotCompatible=true), enforced in CI by NAudioAotSmokeTest
• NAudio.Wasapi targets plain net9.0 (Windows-only at runtime via [SupportedOSPlatform("windows")]), so cross-platform apps can reference it and build on Linux/macOS without EnableWindowsTargeting. The WinRT MIDI backend moved to NAudio.Midi, which now dual-targets net9.0;net9.0-windows10.0.19041.0 (#​1384)
• The NAudio.Uap package is removed — use WasapiPlayerBuilder / WasapiRecorderBuilder
• Packages ship with SourceLink, .snupkg symbol packages and an embedded SPDX SBOM

New capabilities

Each new subsystem has its own tutorial or README; only the headline is listed here.

• Audio effects — a cross-platform NAudio.Effects framework: IAudioEffect / EffectSampleProvider / EffectChain with click-free bypass, dry/wet mix and an optional parameter model, plus a broad effect set (EQ and filtering, dynamics, saturation/lo-fi, delay and modulation, reverb including FFT convolution, pitch shifting, and voice-comms AGC/noise suppression). See Docs/AudioEffects.md
• Modern WASAPI — high-level WasapiPlayer / WasapiRecorder, built via WasapiPlayerBuilder / WasapiRecorderBuilder: IAudioClient3 low latency, MMCSS thread priority, IAsyncDisposable, zero-copy buffers, per-process loopback capture, automatic stream routing that follows the default endpoint (#​942), acoustic-echo-cancellation reference control (#​1223), communications mode, raw mode (#​476), and resample-free bit-depth/channel adaptation in exclusive and low-latency modes. See Docs/WasapiPlayer.md and Docs/WasapiRecorder.md
• Modern ASIO — a new AsioDevice replacing AsioOut: explicit playback/recording/duplex modes, non-contiguous channels, per-channel Span<float> callbacks, driver-reset recovery and per-buffer timing. AsioOut is preserved as a facade. See Docs/AsioMigration.md
• Cross-platform audio files — new NAudio.SoundFile package: read and write WAV/AIFF/FLAC/Ogg-Vorbis/Opus/MP3 via a system libsndfile on Windows, Linux and macOS (the first cross-platform FLAC/Vorbis/Opus encoder in NAudio). See Docs/CrossPlatformAudioFilesWithSoundFile.md (#​1289)
• Linux audio — new NAudio.Alsa package: AlsaOut (IWavePlayer) and AlsaIn (IWaveIn) plus AlsaDeviceEnumerator, backed by libasound. See Docs/PlayAudioFileLinuxAlsa.md and Docs/RecordAudioFileLinuxAlsa.md (#​1182)
• VST 3 hosting — new NAudio.Vst3 package (Windows-only): discover, load and host VST 3 effects and instruments, with parameters, state and .vstpreset presets, native editor windows, program lists/units, latency compensation, and live/offline MIDI-file playback through the shared MIDI pipeline. See the NAudio.Vst3 README and Docs/Architecture/Vst3Hosting.md. VST is a registered trademark of Steinberg Media Technologies GmbH
• Software sampler — new NAudio.Sampler package: polyphonic, cross-platform playback of SoundFont (.sf2) and SFZ instruments and single-sample instruments, rendered as an ISampleProvider (SF2 modulator engine, DAHDSR envelopes, LFOs, modulated filters, reverb/chorus sends, voice stealing, choke groups). See Docs/Sampler.md
• Event-based device notifications — MMDeviceEnumerator.CreateNotificationClient() returns an MMDeviceNotificationClient exposing DeviceStateChanged, DeviceAdded, DeviceRemoved, DefaultDeviceChanged and PropertyValueChanged as ordinary events, so callers no longer implement a COM interface or manage CCW lifetime (#​1395)
• MIDI — NAudio.Midi's portable leg is now cross-platform; new WinRT WinRTMidiIn / WinRTMidiOut and backend-agnostic IMidiInput / IMidiOutput; and a new IMidiInstrument seam (MidiFileSequence / SequencedMidiPlayer / OfflineMidiRenderer / LiveMidiInstrument) giving an end-to-end MIDI-file → audio pipeline that drives the sampler or a hosted VST 3 instrument. MidiFile also reads RIFF-RMID (.rmi) files (#​1236) and MidiFile.Export gains a Stream overload, thanks to @​MaKiPL (#​499)
• Sequencing — a portable NAudio.Sequencing namespace in NAudio.Core (tempo and time-signature maps, transport, EventTimeline, swing, and a sample-accurate per-buffer dispatcher) underpinning MIDI-file playback and the sampler. See Docs/Architecture/Sequencing.md
• Live capture mixing — new NAudio.Extras helpers CaptureMixerInput and RealtimeCaptureMixer capture and live-mix several sources with different sample rates and channel counts (e.g. microphone + system loopback) into one wall-clock-paced stream. See Docs/MixMicrophoneAndSystemAudio.md (#​761)
• Reading audio from streams — AudioFileReader and CachedSound gain Stream constructors, detecting WAV/AIFF from the contents and delegating anything else to Media Foundation, so embedded or in-memory audio plays without a temp file (#​927, #​963). StreamMediaFoundationReader also gains optional contentType / originName hints and Ogg container sniffing (#​952)
• WAV chunk model — WaveFileReader.Chunks with an IWaveChunkInterpreter<T> extension point and built-in interpreters for cue lists, BWF bext (BroadcastExtension, now read and write, with v2 loudness) and LIST/INFO (InfoMetadata); WaveFileWriter gains AddCue, WriteCueList, WriteBroadcastExtension, arbitrary AddChunk and RF64 promotion via WaveFileWriterOptions (#​1013)
• Latency reporting — new IWaveLatency interface in NAudio.Core exposing AverageLatency / CurrentLatency for A/V sync and drift detection, implemented across the playback and capture classes (#​601)
• Sample providers and DSP — new ChannelMixerSampleProvider with ready-made ChannelMixMatrix routings, thanks to @​antiduh (#​982); a new FftProcessor; Span<T> overloads across the codec/DSP surface; reusable building blocks (EnvelopeFollower, DelayLine, Lfo, Oversampler, LinkwitzRileyCrossover, PartitionedConvolver, …); plus improvements to SmbPitchShiftingSampleProvider (#​922), AdsrSampleProvider (#​671) and FadeInOutSampleProvider (#​1136)
• WaveFormatExtensible — new constructors for SubFormat, valid-bits-per-sample and channel mask, readable ValidBitsPerSample / ChannelMask, and a [Flags] Speakers enum for building channel masks (#​1325)
• WASAPI sessions and devices — AudioSessionControl.SetDuckingPreference(bool) (#​760); WasapiPlayer / WasapiRecorder expose DeviceId and DeviceFriendlyName for the active endpoint (#​681)

Breaking changes

The full upgrade walkthrough — every breaking change with before/after code — is
in Migrating from NAudio 2 to NAudio 3. The
highest-impact changes:

• Minimum target framework is now net9.0 (legacy .NET Framework / .NET Standard 2.0 dropped)
• IWaveProvider.Read / ISampleProvider.Read now take a single Span<byte> / Span<float> (was buffer/offset/count) — callers migrate via source.Read(buffer.AsSpan(offset, count)); implementations override the span method
• WaveOutEvent is renamed to WaveOut and WaveInEvent to WaveIn (the old names remain as [Obsolete] subclasses). WaveOut / WaveIn now default to event-driven callbacks; the window-based variants are WaveOutWindow / WaveInWindow in NAudio.WinForms, and WaveCallbackInfo / WaveCallbackStrategy are removed
• WaveOut.DesiredLatency is replaced by BufferMilliseconds, which sizes each individual buffer rather than the total across all of them. WaveIn's default record format changes from 8 kHz mono to 44.1 kHz stereo
• WasapiOut, WasapiCapture and WasapiLoopbackCapture are [Obsolete] in favour of WasapiPlayer / WasapiRecorder (the legacy types still ship and work); WasapiOut's embedded exclusive-mode resampler was removed, though it now adapts bit depth and channels, so only a sample-rate mismatch requires upstream resampling
• The low-level IMMNotificationClient interface and MMDeviceEnumerator.RegisterEndpointNotificationCallback / UnregisterEndpointNotificationCallback are now internal — use CreateNotificationClient() and its events. The raw Core Audio and Media Foundation COM interfaces are likewise internal, and PropertyStoreProperty.Value is now object rather than PropVariant
• Some types moved package or namespace as part of the split — classic Windows MIDI I/O and winmm types to NAudio.WinMM; the DMO/DirectSound types into the new NAudio.Dmo package; plus smaller moves (AudioVolumeLevel, CaptureState, DmoMp3FrameDecompressor). Meta-package consumers are unaffected
• Removed seven members that were already [Obsolete] throughout NAudio 2, each with a direct replacement on the same class: WaveFileWriter.WriteData (both overloads → Write / WriteSamples), WaveFileReader.TryReadFloat (→ ReadNextSampleFrame, which doesn't drop channels on stereo), AcmStream.Convert(int) (→ the overload returning sourceBytesConverted), WaveFormatConversionStream.SourceToDest / DestToSource (unreliable estimates with no replacement — use Position / Length), and AsioAudioAvailableEventArgs.GetAsInterleavedSamples() (→ the overload taking a reusable array, avoiding an allocation per ASIO callback). AsioOut.Volume is kept despite its obsolete notice — it's an IWavePlayer interface member
• AudioMediaSubtypes moved from the NAudio.Dmo namespace to NAudio.Wave. It ships in NAudio.Core, so cross-platform code previously needed using NAudio.Dmo; to name the media subtype GUIDs even on Linux without the DMO package; it now sits alongside WaveFormatExtensible
• SimpleCompressorStream, ImpulseResponseConvolution and NAudio.Extras.Equalizer were removed — superseded by NAudio.Effects (CompressorEffect, ConvolutionReverbEffect, Equalizer)
• CueWaveFileReader, CueWaveFileWriter, BwfWriter and BextChunkInfo were removed, along with WaveFileReader.ExtraChunks / GetChunkData — the unified chunk model on WaveFileReader.Chunks and WaveFileWriter replaces them
• MixingWaveProvider32 was removed — it was an untested float-only mixer that offered nothing over MixingSampleProvider. ImaAdpcmWaveFormat was removed — it was a non-functional stub used nowhere
• WaveFileWriter / AiffFileWriter no longer dispose a caller-supplied stream, matching the readers' ownership rule; only the filename constructor owns and closes the file. IgnoreDisposeStream is no longer needed when writing to a stream you want to keep (#​1040)
• Finalizers were removed from MediaFoundationTransform, MediaFoundationEncoder and MediaBuffer, and MediaType is now IDisposable — call Dispose()
• Core Audio, Media Foundation and DMO errors now throw CoreAudioException / MediaFoundationException, both subclasses of COMException, so existing catch (COMException) keeps working

Notable bug fixes

The sampler, effects and WASAPI subsystems also saw extensive correctness work during
development. The full per-PR list is on the GitHub Release; the fixes most likely to
affect existing NAudio 2 code are:

• WaveFileWriter.WriteSample / WriteSamples: fixed 32-bit WaveFormatExtensible output writing near-silence or corrupt data — both paths ignored the declared SubFormat (#​651)
• ToSampleProvider() now handles WAVE_FORMAT_EXTENSIBLE PCM and IEEE float sources (e.g. multichannel or >16-bit WAV) instead of throwing Unsupported source encoding (#​639); AudioFileReader no longer routes such WAVs through an unnecessary ACM conversion stream
• WaveFileReader / AiffFileReader: malformed headers declaring BlockAlign=0 throw InvalidDataException from the constructor rather than DivideByZeroException later (#​1254); an oversized data chunk length is clamped to the bytes actually present (#​1090); an oversized fmt cbSize no longer throws (#​482)
• AiffFileReader / AiffFileWriter: 8-bit PCM is now read and written as signed two's-complement per the AIFF spec, fixing DC-shifted/garbled playback (#​1178)
• BlockAlignReductionStream.Read: a read larger than the 4-second internal buffer no longer silently truncates the stream — e.g. converting a non-PCM WAV via AudioFileReader (#​1022)
• WaveOut: fixed a race where stopping or disposing faster than the buffer latency could throw a NullReferenceException via PlaybackStopped (#​804); DirectSoundOut: fixed a startup race that could collapse playback immediately (#​759)
• WasapiRecorder, WasapiCapture and WasapiLoopbackCapture: a capture device removed mid-recording no longer crashes the process — RecordingStopped always fires with the originating exception (#​672). Silent packets no longer leak the uninitialised WASAPI buffer as a burst of stale audio
• Fixed an access violation that could crash the process when an endpoint notification fired after RegisterEndpointNotificationCallback — Windows does not AddRef the client, so the CCW was being collected (#​1394)
• AudioClient.Dispose is now idempotent and safe against concurrent disposal (#​1183); MMDevice.Dispose releases the property store deterministically (#​1145); AudioSessionControl supports multiple event clients without leaking (#​1263); AudioEndpointVolume.OnVolumeNotification reports the correct channel (#​351)
• AcmInterop: serialised all msacm32 P/Invokes process-wide, fixing process-killing access violations under concurrent ACM use
• ResamplerDmoStream: fixed an infinite loop on Read after seeking and the loss of the resampler tail at end-of-stream (#​607, #​608); LoopStream.Read no longer spins at 100% CPU when the source can't satisfy a read (#​1338)
• FastFourierTransform.FFT: fixed drifting high-frequency bins at large FFT sizes by carrying the twiddle-factor recurrence in double precision (#​520)
• WdlResampler: backported upstream Cockos WDL fixes, including reinterleaving on channel-count change and denormal flushing in the IIR feedback path (#​800)
• WaveViewer: fixed rendering upside-down (#​801, #​818) and now renders any source format via ToSampleProvider() (#​564)
• Mp3FileReader: fixed false sample-rate-change errors near end of file, and more robust frame parsing against album art and trailing metadata; MidiFile preserves running status across meta events
• WaveFormat.Serialize: PCM formats now write the canonical 16-byte fmt chunk (#​934, #​1098)
• Hardened Media Foundation and DMO interop against COM ref leaks on error paths (#​1293)

Demos and tooling

• NAudioDemo and NAudioWpfDemo were substantially reworked against the new APIs, including a rebuilt WASAPI Recorder panel driven by WasapiRecorderBuilder, transport/volume/position controls across the playback panels, and a Graphic EQ panel on NAudio.Effects
• The network chat demo is now UDP-only with a bounded jitter buffer and Opus codecs (via Concentus, replacing the vendored NSpeex binary), and gained a tutorial
• The documentation site (tutorials plus a generated API reference) is published to GitHub Pages from Docs/ and the source XML comments. Every package's projectUrl and README now point at it; nuget.org still links the GitHub repo via the package's repository metadata

v2.4.0: NAudio 2.4.0

• Added DeviceCount and GetCapabilities static methods to WaveOutEvent so output
  devices can be enumerated without referencing NAudio.WinForms (#​1331, #​777)
• Fixed WASAPI and Media Foundation interop under Unity's Mono runtime, which marshalled
  formatted class parameters as COM interfaces; they are now explicitly marked
  [MarshalAs(UnmanagedType.LPStruct)] (#​1414)

v2.3.0

• Performance improvements for PropertyStore and Core Audio property access (#​1206)
• Improved multi-channel playback compatibility in WASAPI exclusive mode (#​1234)
• Fixed a bug that prevented WasapiCapture from using exclusive mode (#​1122)

• PropVariant now supports VT_EMPTY by returning null (#​1071)
• Better exception when calling disposed AcmStream.Convert (#​1108)
• Fixed AcmStreamHeader finalizer crash with corrupted data (#​1199)
• Added net6.0 targets for NAudio.Asio and NAudio.WinMM to remove registry dependency (#​1139)
• Updating TFMs, modernizing the UAP project to WinUI
