Ez-Audi

A lightweight Linux/WASM compatible audio library based on cpal

Features (as of now):

• Read and play LPcm WAVE (.wav) files
• Apply modifiers to the samples for Volume, Looping, etc..
• Control over the raw audio samples
• Get audio file metadata

Supports (as of now):

• Linux
• LPcm WAVE files
• WASM (See Usage in WASM environment) (Windows is has not been tested yet)

Get started

use ez_audi::audio_files::WavAudio;
use ez_audi::public_traits::*;

let wav_audio = WavAudio::build_from_path("test_assets/u8-stereo-lpcm.wav").unwrap();

// Creates an audio player, keep it in scope to keep the audio playing
let player = wav_audio.play_on_default_output(false).unwrap();

std::thread::sleep(std::time::Duration::from_secs(2));

Usage in WASM environment:

Whilst ez-audi is fairly easy to use in WASM, there are some surprises:

• Playback needs to be started/resumed inside a user gesture (button click, etc.). Playback does not start automatically.
• You most likely want to get files (or their data at least) from your website through GET requests. I would recomend using the Cursor struct from std to turn a Vec of bytes into a reader. Whilst the functions for building struct from files/paths still exists, they are useless in WASM.
• Note that, like in all other enviroments, you need to keep your SamplesPlayer in memory for playback.

What is left to do:

• Pretty much everything, don't use this in any serious projects unless you enjoy relying on unstable, buggy code
• The documentation is also very much lacking
