  • Symphonia v0.5.2: Audio decoding in safe Rust, now often faster than FFmpeg!
    6 projects | /r/rust | 24 Jan 2023
    Regarding improving the API for 0.6, something that bugs me about the current Rust audio ecosystem is that everyone is reinventing the wheel with their own audio buffer types each with their own API that downstream users have to learn. This makes it more of a hassle to pass audio data from one library to another than it should be. I've been contributing to the audio crate which provides buffer structs and traits for working with audio buffers with a common API regardless of their layout in memory. I have a work-in-progress branch for Rubato refactoring it to use the audio crate, though there's a bit more work to do in the audio crate to complete that. Would you be interested in using the audio crate in Symphonia?

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