novolis-audio

Cross-platform audio for Novolis apps — outside any graphics engine.

Packages

Game SFX (miniaudio)

Package	Role
Novolis.Audio	Meta package (abstractions + runtime)
Novolis.Audio.Abstractions	IAudioEngine, ISoundHandle, NullAudioEngine
Novolis.Audio.Runtime	Generated facades + MiniaudioAudioEngine
Novolis.Audio.Bindings	Generated [LibraryImport] to novolis_audio
Novolis.Audio.Native	RID native binaries (transitive)
Novolis.Audio.Manifests	C# binding manifests (maintainers)
Novolis.Audio.Output.Abstractions	Game master-volume / device probe contract
Novolis.Audio.Output.NAudio	NAudio probe of Windows default render endpoint

Voice / PCM (TTS)

Package	Role
Novolis.Audio.Core	PCM buffers, WAV read/write
Novolis.Audio.Codecs	Codec contracts (WAV in Core today)
Novolis.Audio.Filters	PCM filters (band-limit, EQ)
Novolis.Audio.Effects	PCM effect chains and pipelines
Novolis.Audio.Playback	PCM playback (NaudioPcmPlayback)
Novolis.Audio.Voice	SpeakAsync / WriteToFileAsync facade
Novolis.Audio.Voice.Abstractions	TTS contracts
Novolis.Audio.Voice.SherpaOnnx	Sherpa-ONNX synthesizer
Novolis.Audio.Voice.Kokoro	Kokoro ONNX offline TTS
Novolis.Audio.Voice.EdgeTts	Online Edge Read Aloud TTS (MP3; requires network)
Novolis.Audio.Voice.Manuscript	Books / audiobook pipeline on EdgeTts
Novolis.Audio.Voice.Phraseology	ICAO phraseology
Novolis.Audio.Voice.Profiles	Neutral base-voice archetypes
Novolis.Audio.Voice.Design	Preset drafts, validation, preview, GPR code export

Native game playback uses a miniaudio C shim (novolis_audio.dll). Voice uses Sherpa ONNX + NAudio (separate stack). Edge/Manuscript is a parallel MP3 path (not IVoiceSynthesizer).

Live music

Package	Role
Novolis.Audio.MusicTheory	Typed notes, chords, durations, tempo, instruments
Novolis.Audio.Patterns	Immutable pattern graph
Novolis.Audio.Live	Compiler, scheduler, program swap state
Novolis.Audio.Live.Dsl	Authoring helpers
Novolis.Audio.Live.Protocol	MessagePack IPC DTOs + REPL client
Novolis.Audio.Live.Visuals	Graph / analysis projections
Novolis.Audio.Live.Render	v0 NAudio oscillator synthesis

See docs/live.md. Host process lives in LiveStudio (novolis-apps), not as a packable audio project.

typed music model
  → immutable pattern graph
  → live compiler / swap queue
  → host process (+ Render)
  → REPL + visual clients

Transport: Novolis.Transports.LocalIpc (GitHub Packages).

Quick start (game SFX)

using Novolis.Audio;
using Novolis.Audio.Runtime;

await using IAudioEngine engine = new MiniaudioAudioEngine();
if (!engine.Start())
    return;

var sound = engine.LoadSound("click.wav");
engine.Play(sound);

Quick start (voice)

using Novolis.Audio.Voice;

IVoiceService voice = new VoiceServiceBuilder().BuildService();

await voice.SpeakAsync("Tower, ready for departure.");
await voice.WriteToFileAsync("Cleared for takeoff.", new FileInfo("atc.wav"));

Maintainer pipeline

dotnet run --project codegen/Novolis.Audio.Pipeline -- run maintainer
dotnet build Novolis.Audio.slnx -c Release
