Go bindings for the PortAudio audio I/O library

Overview

portaudio

This package provides an interface to the PortAudio audio I/O library. See the package documentation for details.

To build this package you must first have the PortAudio development headers and libraries installed. Some systems provide a package for this; e.g., on Ubuntu you would want to run apt-get install portaudio19-dev. On other systems you might have to install from source.

Thanks to sqweek for motivating and contributing to host API and device enumeration.

    Go 1.6beta1 - Changes to CGO pointer passing break portaudio

    Hi,

    I tried compiling portaudio against the new golang 1.6 beta 1 release and it breaks port audio bindings. As a part of 1.6 they tighten the rules regarding Go pointers being passed into C memory.

    This means that while programs compile, at run-time they abort. See below for the noise.go example from the distribution.

    This example worked fine on 1.5.x and lower.

    The related changes are described in https://github.com/golang/go/issues/12416.

  • Playback issue with 24 bitsPerSample audio content

    Playback issue with 24 bitsPerSample audio content

    Hi, unfortunately I am not able to play back 24/96 flac files. Such content usually gives me an "Output underflowed" error message or just trash noise. Here some free 24bps content:

    http://www.lindberg.no/hires/test/2L-125_stereo-88k-24b_04.flac

    When I call OpenDefaultStream(), do I have to hand over a buffer created with make([]portaudio.Int24,framesPerBuffer) instead of make([]int16,framesPerBuffer)? Anything else I should be aware of when trying to play back 24bps audio content? Thank you.

    cross-compiling

    Hi! I'm using MacOS, and would like to create app that works with microphone, ready-to-use on any platform (Windows, Linux, Mac)... so the question is - how to achieve this on my Mac? Or... from any other OS (not a big deal to use Vagrant and build from there).

  • Working example with go-mpg123

    Working example with go-mpg123

    I'm working on a project where I will be using go-mpg123 (a port of the libmpg123 bindings in golang) but I'm having a hard time getting that library to play nicely with port audio.

    I've gotten reasonably far in this gist but the audio playback is really distorted for some reason and I cant figure out what would be the issue.

    Has anyone been able to get these two libraries successfully working together, and if so is there anything blatantly wrong with my code example? If I'm able to get something working, would this be a good candidate for the examples directory?

  • unable to open on a device

    unable to open on a device

    Hi everyone,

    First of all, great job everyone involved in the construction of this piece of software.

    I have been using portaudio very successfully for the past weeks for developing a low delay app for musicians https://bitbucket.org/claudio_ortega/jambridge/src/master/doc/jambridge-README.md

    Here's the bad news, I've run today into an issue, which seems to be very likely system dependent.

    I am using an AudioBox USB96 interface, which has been working and still works just fine. Please find at the bottom the test case with the minimum piece of code that shows the failure. The problem is in the call to OpenStream() which returns "PortAudio Internal Error"

    The test passes in these two test beds:

    • (1) ubuntu 20.02 box
    • (2) iMac Late 2009 running Catalina (w/dosdude adaptor)

    The exact same test does not pass in my third test bed:

    • (3) Mac Mini 2018 w/ Big Sur.

    In all cases I am with go1.15.x, and I have no 'user' applications opened. Also in all cases I've verified that the name for the device picked up by the call to DefaultInputDevice is always the same: "AudioBox USB 96", which is the one that I expect and the one I want.

    The audio parameters used in the test are: 44.1k/64samples/16bits/1channel. However, I've tried with different combinations of sampling freq and buffer length, all working fine on 1,2 above, but none of those have worked on (3).

    I hope somebody has run into this issue, and hopefully might shed some light on it.

    Thanks again for the great work put on this library.

  • Running mp3 example with hajimehoshi/go-mp3 library

    Running mp3 example with hajimehoshi/go-mp3 library

    Hi!

    I am trying to reproduce the mp3 example but using a different mp3 library. My current attempt is available in this gist.

    The code compiles, the sound is playing, but it is heavily distorted - there is a glitch per each read-write cycle. One can see that by tweaking the bufsize variable - the smaller the buffer, the higher the glitching frequency.

    I took a look at this issue, but I cannot quite figure out what is the problem in my case :(

    Thanks! Yuriy

  • Issues installing on Windows

    Issues installing on Windows

    Hi,

    I am trying to attach to audio streams on windows with go and have found many sources pointing to this package but I am having issues when running the go get command. Here are the steps I have taken so far:

    1. Downloaded the source for PortAudio
    2. Followed the instructions found here: https://github.com/PortAudio/portaudio/wiki/Notes_about_building_PortAudio_with_MinGW
    3. Added my PortAudio path to my PKG_CONFIG_PATH environment variable
    4. Run go get github.com/gordonklaus/portaudio

    When I run the final command I get this error:

    # github.com/gordonklaus/portaudio
    C:\Users\user\go\pkg\mod\github.com\gordonklaus\[email protected]\portaudio.go:16:10: fatal error: portaudio.h: No such file or directory
       16 | #include <portaudio.h>
          |          ^~~~~~~~~~~~~
    compilation terminated.
    

    When looking at the file mentioned here I find that line 16 is contained in a multi line comment, so the fact that it is complaining makes no sense to me. Is there something that I have done wrong?

    Hi,

    I'm using this library to read an audio stream (of a click track) and determine when a click happens to start a playback of a light show.

  • Determining FramesPerBuffer For Infinite Stream Time

    Determining FramesPerBuffer For Infinite Stream Time

    Currently I am working to record audio via the input device and send it through a TCP Conn to a client who will then use the same library to play the audio. Before I have tried to face the issue of piping the stream data to a socket I wanted to figure out how to approach the issue of streaming for an unknown or infinite amount of time. Programmatically how would I go about this process as some of the OpenDefaultStream requires a length of frames per buffer to be provided but how could that be done if I plan to stream data indefinitely between an input device through a socket connection to an output device on another machine with no time limit?
