audio - Official Wyn Package

Audio utilities for Wyn: format detection and audio math. Pure Wyn, no system dependency. (Decode/encode/playback via C bindings is future work.)

Install

wyn pkg install github.com/wynlang/audio

Usage

import audio

// Format detection from file extension
print(audio.audio_format("song.mp3"))            // mp3
print(audio.audio_format("voice.flac"))          // flac
print(audio.audio_is_supported("clip.ogg"))      // true
print(audio.audio_is_supported("notes.txt"))     // false

// Audio math: CD-quality stereo = 176400 bytes/sec
var bps = audio.audio_bytes_per_second(44100, 2, 16)
print(bps)                                       // 176400

// Estimate duration of a 10 MB file in seconds
print(audio.audio_duration_estimate(10485760, bps))  // 59
