Build StaticSoundData from buffer

[dcvz]

Hello all,

I’m attempting to use this in a game (more similar to an emulator) where I’m receiving audio data in a u8 buffer. I tried looking around but it seems there’s no real way of creating a sound data object that I can just send off to play. I already know the num of channels and rate.

It could also be this library isn’t meant to be used this way. Any help would be appreciated :)

Trying do something like this now (inspired by the from_file source) - but getting choppy sound. So I guess this is the way just gotta get the conversion right.

let buffer = buf.to_vec();
let mut frames = vec![];

for i in (0..buffer.len()).step_by(4) {
    let left = i16::from_le_bytes([buffer[i], buffer[i + 1]]);
    let right = i16::from_le_bytes([buffer[i + 2], buffer[i + 3]]);
    frames.push(Frame::new(left.into(), right.into()));
}

let sound_data = StaticSoundData {
    sample_rate: 44_100,
    frames: Arc::new(frames),
    settings: StaticSoundSettings::default(),
};

To be clear, the audio bytes weren't an existing audio file format, like wav or mp3, right?

They were not, no. It was audio produced in engine from other file formats. Think an emulator. I couldn’t get it to not be choppy and in the end went with using cpal directly but it might still be a use case for others - since using cpal has a higher entrance barrier.
