NAudio.Wasapi

WASAPI and Media Foundation support for NAudio. Targets net9.0 and is Windows-only at runtime (guarded by [SupportedOSPlatform("windows")]), so cross-platform apps can reference it and build on any OS without EnableWindowsTargeting. Live WinRT MIDI moved to the NAudio.Midi package.

What's included

WASAPI playback — WasapiOut (shared and exclusive mode, event-driven callbacks), plus the modern WasapiPlayer / WasapiPlayerBuilder
WASAPI capture — WasapiCapture for microphone/line-in capture, WasapiLoopbackCapture for system audio, plus the modern WasapiRecorder / WasapiRecorderBuilder
Device enumeration — MMDeviceEnumerator, MMDevice, per-device volume, mute, peak/RMS metering, notification callbacks
Media Foundation — MediaFoundationReader and MediaFoundationEncoder for MP3, AAC/MP4, WMA and any installed MFT codec; MediaFoundationResampler
Audio Session API — per-session volume, mute, and metering

For DMO effects (echo, chorus, reverb, etc.), the DMO MP3 decoder, the DMO resampler, and DirectSoundOut, see the separate NAudio.Dmo package.

When to use it

Use this package whenever you want modern Windows audio APIs: low-latency playback, loopback capture of the system mixer, per-application volume, or codec support via Media Foundation. The package is being actively modernized to use GeneratedComInterface and source-generated COM interop.

See the NAudio documentation site for tutorials and the full API reference, or the GitHub repository for full documentation and tutorials.

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)
