    Rust audio playback library

    I have tried the crate already but I did not find a way to change the parameters while the background thread is playing the song.

  • cpal

    Cross-platform audio I/O library in pure Rust

    I had to do something similar to this a while back. I used cpal.

  • rubato

    An asyncronous resampling library written in Rust (by HEnquist)

    If you want to change tempo and pitch together, that's resampling. You can use Rubato's asynchronous resamplers for that.

  • creek

    Realtime disk streaming IO for audio (by MeadowlarkDAW)

    Rodio is high level and likely not really suited to what you're trying to do. Rodio is nice if you just want to play sound files and don't care about the details. If you want to manipulate audio in realtime, Creek is likely a better fit. You can take a look how I am combining Creek and Rubato for realtime tempo changes in the DJ application I am writing.
