PortAudio bindings and wrappers for Rust.

PortAudio is a free, cross-platform, open-source, audio I/O library.

rust-portaudio is still under development, so there may be bugs - please feel free to add an issue or even better, submit a PR!

To use rust-portaudio in your own project, add it to your Cargo.toml dependencies like so:

[dependencies]
portaudio = "X.Y.Z"

Installation

rust-portaudio will try to detect portaudio on your system and, failing that (or if given the PORTAUDIO_ONLY_STATIC environment variable on the build process), will download and build portaudio statically. If this fails please let us know! In the mean-time, you can manually download and install PortAudio yourself.

On Mac OS X, you may need to install manually portaudio and pkg-config (using brew, run brew install portaudio and brew install pkg-config)

rust-portaudio is built using cargo, so just type cargo build at the root of the rust-portaudio repository.

You can build the tests and examples with cargo test, and the documentation with cargo doc.

  • Implement / bind non-blocking API (portaudio callback)

    Implement / bind non-blocking API (portaudio callback)

    Portaudio provide a non-blocking API using callback function which is called each time some new data are coming. For now this functionality is not implemented in rust-portaudio as a user can do the same thing using a rust task and calling the blocking api inside of it. Maybe we can bind this functionality too as the native implementation is probably more effective.

  • Callback function never called - arm

    Callback function never called - arm

    I'm working on getting rust-portaudio to work on my bananapi. On the bananapi I want to ignore the builtin audio devices and use a USB soundblaster instead. I'm able to specify that device using a device index, but I get a lot of error messages concerning the builtin audio device. The results is I don't hear any audio. I'm not sure what the cause might be, though the error messages look suspicious. PortAudio doesn't seem to be too happy.

    FWIW, I am able to play audio through the soundblaster using other sound sources on that computer. aplay works, as does supercollider running through jack1.

    Output from my test program is below. (portaudio startup is at line 89 in my test program).

  • Occasional Runtime SIGSEGV, Segmentation fault when using a non-blocking Stream

    Occasional Runtime SIGSEGV, Segmentation fault when using a non-blocking Stream

    This issue hasn't shown itself in any of the tests in the rust-portaudio, sound_stream, dsp-chain or synth crates, however it has appeared when trying to instantiate a non-blocking stream while following it immediately with a gl window event loop (using piston_window to be precise).

    The problem disappears if the event polling is removed (i.e. for event in window {}).

    @bvssvni mentioned the possibility of alignment issues - it could be worth looking into this.

    Here is the backtrace provided by gdb when the segfault is hit:

    Program received signal SIGSEGV, Segmentation fault.

    @niclashoyer has been running into issues with rust-portaudio on Linux. The blocking stream immediately underruns and breaks from the loop, while the non-blocking stream shows some warning messages however seems to run fine. Perhaps we are missing some platform specific ALSA implementation? @jeremyletang any ideas? Do you test on linux?

    Rust-portaudio crashes (doesn't panic) with "signal 11"

    I started a project that uses rust-portaudio. The example provided in this repo seems to work, but when I try to generate and play a generated sound wave by myself, I run all kinds of strange phenomena.

    My code is in https://github.com/golddranks/ongen

    First of all, trying to pass it just a buffer of zeros, it emits loud buzzing noise. (With buffer of 0.00s, it should be just silent, right?) I thought this was maybe problem in latency and the output stream was starving, and thus producing clicks whenever the buffer was consumed and a new buffer was provided. I set the latency looser, default_high_output_latency, with no audible difference.

    Then I tried to set the frames_per_buffer value higher. Originally I had it in 256 like in the example. Changing the buffer size to 512 produced audible difference, but still just noise, all together. When I set it to 1024, Portaudio started crashing, not panicking in Rust-style but like this: Process didn't exit successfully:target/ongen(signal: 11)

    Do you have any idea how to fix these issues? It is surely the C library side that crashes with "signal 11"? Is buffer of 1024 outrageous in size? Any idea how to fix the buzzing?

  • Both blocking and non-blocking examples use 100% CPU

    Both blocking and non-blocking examples use 100% CPU

    When I run the two streaming programs from the examples directory, they take 100% of the CPU. When I limit it to just reading the input, the same happens, and it seems the main loop just gets 0 bytes and keeps looping like mad until finally a full buffer arrives. Is that a problem in rust-portaudio or in the lower portaudio library?

  • Change Stream to hold a generic reference to PortAudio

    Change Stream to hold a generic reference to PortAudio

    Currently Stream requires a &'a PortAudio. This prevents placing both into the same structure. Perhaps this relationship could be changed such that Stream requires a T where T: Deref<PortAudio> such that you could use an Rc<PortAudio> instead, allowing greater flexibility when structuring code.

  • Relicense under dual MIT/Apache-2.0

    Relicense under dual MIT/Apache-2.0

    Why?

    The MIT license requires reproducing countless copies of the same copyright header with different names in the copyright field, for every MIT library in use. The Apache license does not have this drawback, and has protections from patent trolls and an explicit contribution licensing clause. However, the Apache license is incompatible with GPLv2. This is why Rust is dual-licensed as MIT/Apache (the "primary" license being Apache, MIT only for GPLv2 compat), and doing so would be wise for this project. This also makes this crate suitable for inclusion in the Rust standard distribution and other project using dual MIT/Apache.

    How?

    To do this, get explicit approval from each contributor of copyrightable work (as not all contributions qualify for copyright) and then add the following to your README:

    ## License

Licensed under either of
 * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0)
 * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)
at your option.

### Contribution

Unless you explicitly state otherwise, any contribution intentionally submitted
for inclusion in the work by you shall be dual licensed as above, without any
additional terms or conditions.

    and in your license headers, use the following boilerplate (based on that used in Rust):

    // Copyright (c) 2015 t developers

    And don't forget to update the license metadata in your Cargo.toml!

  • Use Cargo's

    Use Cargo's "Build Script Support" and include PortAudio with the repo as a static lib.

    I'm unsure how tricky this would be, but it would be awesome if we could have Cargo automatically handle the downloading and installation of the PortAudio lib - would make it much easier for other Rusty users to pick our libs :)

    The info on Cargo's build script support is here.

    Looking for Maintainers

    Hi all!

    I no longer have the time or motivation to manage the rust-portaudio crate. These days, most of my efforts have been going into CPAL - a pure-Rust alternative. As a result, I find it difficult to prioritise issues and PRs here.

    If anyone would like to step in as the maintainer for the crate they would be more than welcome. I'd be happy to add them as an administrator to the RustAudio organisation if they are not already so.

  • Stream API is unsound

    Stream API is unsound

    The callback is passed a 'static reference to the audio buffer (here and here; also see Output and Duplex), which allows the reference to outlive the duration of the callback. The lifetime of the buffer should be appropriately constrained to the duration of the callback.

  • Huge output gaps in duplex mode

    Huge output gaps in duplex mode

    When using duplex mode, I'm getting serious gaps in the audio output. This is in release mode, and even if I increase the frames per buffer to buffers sizes corresponding to multiple seconds, there are gaps between the buffers. The gaps are approximate 1 sec long. A minimal example to reproduce looks like this:

    use std::io;
use portaudio as pa;

const CHANNELS: i32 = 2;
const SAMPLE_RATE: f64 = 44_100.0;
const FRAMES_PER_BUFFER: u32 = 1024;

fn main() {
    run().unwrap()
}

fn run() -> Result<(), pa::Error> {
    let pa = pa::PortAudio::new()?;

    let mut settings = pa.default_duplex_stream_settings(
        CHANNELS,
        CHANNELS,
        SAMPLE_RATE,
        FRAMES_PER_BUFFER,
    )?;
    settings.flags = pa::stream_flags::CLIP_OFF;

    let callback = move |pa::DuplexStreamCallbackArgs { in_buffer, out_buffer, frames, time, .. }: pa::DuplexStreamCallbackArgs<f32, f32>| {
        for i in 0 .. out_buffer.len() {
            out_buffer[i] = ((i * 2 % 1000) - 500) as f32 / 1000.0;
        }
        pa::Continue
    };

    // Start stream
    let mut stream = pa.open_non_blocking_stream(settings, callback)?;
    stream.start()?;

    // Wait for user input to quit
    println!("Press enter/return to quit...");
    let mut user_input = String::new();
    io::stdin().read_line(&mut user_input).ok();

    stream.stop()?;
    stream.close()?;

    Ok(())
}

    I can run the same example in other languages just fine, which indicates it is a problem in the Rust binding themselves.

    The non-duplex variant using default_output_stream_settings also runs fine.
