AudioStreamer sample

A separate MAUI consumer of the local Plugin.Maui.AudioStreamer reference package. It generates a 16-second original instrumental loop in C#, sends PCM chunks through BasicMessageChannel, and plays them with Kotlin AudioTrack or Swift AVAudioEngine. Choose Play for one pass or Loop for continuous music. It exposes signal level, pause/resume, stop, native buffer occupancy, and mean enqueue wait.

See the plugin guide for build/run instructions, format, backpressure, and lifecycle. The app references only the plugin package; its native adapters and NativeChannels dependencies arrive transitively. Android requires API 31+.

Startup silently verifies native playback, queue bounds, pause/resume, cancellation, drain, and a clean restart. It logs AUDIO_SAMPLE PASS … and writes audio-result.txt in application data. The foreground app stops playback when backgrounded. System media volume still applies to the music. The default signal level is 16%; if playback is quiet, raise the device’s media volume.

“Sunny Steps” is an original eight-bar melody with piano-style notes, bass, and a soft beat, synthesized by MusicGenerator at 120 BPM. Its score and synthesis code are part of this MIT-licensed repository; there is no downloaded recording, third-party song, streaming service, or additional asset license. The demo sends 50 ms PCM chunks to leave headroom for emulator bridge latency while retaining the native half-second buffer limit.
