NAudio.WinMM

Windows Multimedia (WinMM / winmm.dll) bindings for NAudio. Windows-only (net9.0-windows).

What's included

• Playback — WaveOut for playing audio via the legacy WinMM API. The window-callback variant lives in NAudio.WinForms as WaveOutWindow
• Recording — WaveIn for capturing audio from input devices. The window-callback variant is WaveInWindow in NAudio.WinForms
• MIDI I/O — MidiIn / MidiOut for sending and receiving live MIDI messages
• ACM — Audio Compression Manager wrappers: AcmStream, AcmMp3FrameDecompressor, driver enumeration
• Device enumeration and capability queries for WinMM audio and MIDI devices

When to use it

Use this package when you need the classic WaveOut/WaveIn APIs — useful for broad compatibility with older Windows versions, for very simple playback/capture, or when you specifically want ACM codecs. For lower-latency playback, system loopback capture, or modern device enumeration prefer NAudio.Wasapi.

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