Guides to working with oneaudio: how-tos, migrations and comparisons.

- [Read and write WAV files in C#](https://recursiveai.org/oneaudio/articles/wav-files-csharp/) (October 27, 2026): Read WAV files in C# as floats or exact integers and write 16-bit, 24-bit and float WAV with optional dither, including RF64 for files over 4 GB, on any OS.
- [Record audio in C#](https://recursiveai.org/oneaudio/articles/record-audio-csharp/) (October 27, 2026): Record from the microphone in C# on Windows, Linux and macOS: write a WAV file while recording, show a live input level, and handle missing devices.
- [Play audio in C#](https://recursiveai.org/oneaudio/articles/play-audio-csharp/) (October 27, 2026): Play MP3, WAV, Ogg, Opus and FLAC files in C# on Windows, Linux and macOS with one API, pick an output device and play samples you generate.
- [Encode and decode Opus in C#](https://recursiveai.org/oneaudio/articles/opus-csharp/) (October 27, 2026): Encode and decode Opus in C# with managed code: WAV to Ogg Opus files, raw 20 ms voice packets with loss concealment, and a comparison with Concentus.
- [Decode Ogg Vorbis in C#](https://recursiveai.org/oneaudio/articles/ogg-vorbis-csharp/) (October 27, 2026): Decode Ogg Vorbis in C# with managed code on any OS: stream floats, seek to an exact frame, play chained files, convert OGG to WAV, and compare with NVorbis.
- [A zero-allocation audio mixer for C# games](https://recursiveai.org/oneaudio/articles/game-audio-mixer-csharp/) (October 27, 2026): Game audio in C#: a real-time mixer with buses, ducking, reverb and a limiter that allocates nothing on the audio thread, played directly or via MonoGame.
- [Read and write FLAC in C#](https://recursiveai.org/oneaudio/articles/flac-csharp/) (October 27, 2026): Decode and encode FLAC in C# on any OS with managed code: exact integer samples, MD5 verification, tags, WAV to FLAC at levels 0 to 8, and 24-bit output.
- [Audio in .NET without FFmpeg](https://recursiveai.org/oneaudio/articles/audio-without-ffmpeg-dotnet/) (October 27, 2026): When you can drop FFmpeg, FFMpegCore or Xabe.FFmpeg for audio in .NET: ffmpeg commands mapped to managed C# calls, and the jobs that still need FFmpeg.
- [Resample audio in C#](https://recursiveai.org/oneaudio/articles/resample-audio-csharp/) (October 26, 2026): Resample audio in C# with pure .NET code on any OS: 44.1 kHz to 48 kHz or 16 kHz, files or float buffers, streaming, with no Media Foundation or native code.
- [Migrating from NAudio](https://recursiveai.org/oneaudio/articles/migrate-from-naudio/) (October 26, 2026): Move NAudio code to OneAudio: AudioFileReader, WdlResamplingSampleProvider, WaveFileWriter, FLAC and Opus encoding, and AlsaOut or WasapiPlayer playback.
- [Loudness normalization in C#](https://recursiveai.org/oneaudio/articles/loudness-normalization-csharp/) (October 26, 2026): Measure and normalize loudness in C#: integrated LUFS, loudness range and true peak per EBU R 128 and ITU-R BS.1770, to -14 or -23 LUFS, in pure .NET code.
- [Decode MP3 in C#](https://recursiveai.org/oneaudio/articles/decode-mp3-csharp/) (October 26, 2026): Decode MP3 files in C# on Windows, Linux and macOS with pure .NET code: float samples, MP3 to WAV on disk or in memory, streaming, seeking and gapless length.
- [Choosing a C# audio library](https://recursiveai.org/oneaudio/articles/csharp-audio-library/) (October 26, 2026): C# audio libraries compared: NAudio 3, OwnAudioSharp, FFMpegCore, CSCore and OneAudio, by playback, recording, codecs and native code, each fact sourced.
