## What it is
NAudio is an open-source audio and MIDI library for .NET, providing classes for playing, recording, converting, and manipulating audio. Version 3 splits functionality into focused packages with a cross-platform core (Windows, Linux, macOS) plus Windows-specific WASAPI, ASIO, WinMM, and DMO stacks.

## Use cases
- play mp3 and wav files in a .NET app
- record audio from microphone in C#
- convert audio files between formats
- read and write MIDI files
- apply audio effects like reverb or EQ
- low-latency multichannel audio playback via ASIO
- capture system audio loopback on Windows
- build a software synthesizer or sampler

## When to choose
- you need audio playback, recording, or manipulation in a .NET application
- you need MIDI file parsing or MIDI I/O on Windows
- you want a mature, well-documented audio library with permissive MIT licensing
- you need Windows-specific audio APIs like WASAPI, ASIO, or Media Foundation codecs

## When to avoid
- you need audio processing outside the .NET ecosystem
- you require legacy .NET Framework or .NET Standard 2.0 support
- you need full cross-platform feature parity — many advanced features (WASAPI, ASIO, DMO) are Windows-only
- you need video processing, not audio

## Facets
- artifact type: library
- maturity: stable
- function: audio-processing, sdk
- domain: media, cross-platform, developer-tools
- platform: dotnet, windows, cross-platform
- tags: midi, wasapi, asio, dsp, playback, recording, csharp, audio-effects, sampler, audio, linux, macos
