Go bindings for miniaudio library.
Requires cgo but does not require linking to anything on the Windows/macOS and it links only -ldl on Linux/BSDs.

Hello there and thank you for this wrapper!
I want to know how stable the API is and whether you are planning to do any versioned releases?
I intend to use the audio library and would like to extend it to support multiple operations in parallel; Right now for instance there's only one callback possible at a time. Changing this would require API-breaking changes.
Hence my question whether you are planning to do a v1 release after such a contribution, or a v1 release now, followed by a v2 release.
The formal parameters of InitDevice list: context Context, deviceConfig DeviceConfig, deviceCallbacks DeviceCallbacks but the documentation says: The device ID can be nil, in which c...
There is no device ID in the parameterlist. It would be nice if there was, as I cannot select a specific device now with InitDevice.
Can the documention be in-line with the parameters?
Can you explain how to init a specific device, given it's device ID?
Is there a way to select between PulseAudio and ALSA at runtime?
one commit prior works but now we get this on macos (13):

FAIL github.com/gen2brain/malgo 2.208s```
malgo does not list iOS as a supported platform, but macOS. As far as I understand, Miniaudio is based on Core Audio for both macOS and iOS. So I am surprised by this restriction.
Is this a hard constraint, i.e. is there a technical burden that prohibits deployment, or is it just not tested?
Many thanks for an answer to help me out!

You can see that with go mod enabled, I cannot install this package at all. It installs without go mod.
there are lots of fixes between v0.10.29 and v0.10.35
Hello, when I run the capture example on my Mac-mini (2018, Catalina 10.15.3) it exits early with this error:
Assertion failed: (tNext <= framesReadFromClient+1), function ma_src_read_deinterleaved__linear, file /Users/craig/go/pkg/mod/github.com/gen2brain/[email protected]/miniaudio.h, line 30529
The Mac mini doesn't have a microphone, but I have a guitar usb interface that is considered the default input device in sound preferences. Also, I'm running it in iterm, which does have access to the input device in the privacy settings. Would you expect this setup to work?
Hi everyone,
I am trying to capture audio with minimum latency (10mSec) using malgo.
I am having a problem.
I am not sure if it is myself making a mistake or I have hit a bug in malgo.
I do not know frankly.
The brief statement is:
-- I am using malgo 0.10.19
-- I need to capture from a predefined device @ 44.1ks/sec, with 16 bits, and 1 channel
-- during a 10 seconds take, the number of bytes obtained is very different from the expected
Details:
The device used as input is being chosen out from the list of available devices produced by malgo itself,
notice that the test selects one of the pre-listed devices.
https://bitbucket.org/claudio_ortega/jambridge2/src/master/src/audio/test/device_capture_test.go
It fills in the config structure with the selected capturing device ID. Then it starts the device, and then it waits for 10 seconds for the capturing device to inject the samples in the callback before stopping the capture and ending the test.
** Expected:
The total number of bytes expected after 10 seconds is something around the theoretical
2*44.1ks/sec*10sec = 882,000 bytes
** Observed:
The config for the device occurs between lines 37 and 44.
The output produced by the test case into the console is in here:
https://bitbucket.org/claudio_ortega/jambridge2/src/master/notes/bug-report.txt
between lines 75 and 128
Notice that the number of bytes obtained is 52800, when the expected is 882000
It might be me making a mistake, that would be great to know.
Can anybody see if I am missing something obvious here?.
Unable to dynamically pull a device ID from config file.
I've tried defining struct with device being int, string and interface. No combination seems to work.
I usally hammer my way through to solve issues, but this one has me stumped.
deviceConfig := malgo.DefaultDeviceConfig(malgo.Capture)
deviceConfig.Capture.Format = malgo.FormatS16
deviceConfig.Capture.Channels = 1
// deviceConfig.Capture.SampleRate = 44100
deviceConfig.Capture.DeviceID = device
Ideas?
I would want to get info about individual audio stream or session from and app in oder to control its volume apart from system master volume.
Is it even possible and how would you approach something like this using Malgo?
Probably the right place to ask this would be mini_al repo, but maybe Go bindings do it differently.
I would like to have an app that does sound capture and playback at the same time through the same device. My approach of making a config with two callbacks (send and recv) doesn't seem to work on Linux/PulseAudio and Linux/Alsa. If I initialize device with Capture mode - only capture happens, if I do it in Playback mode - only playback happends. If I use a bitmask - nothing changes (because Playback mode = 0). My attempt to open the same default device in two goroutines results in various crashes.
So I wonder what is the correct way to do this? I haven't found any hints in the docs yet, and the examples only demonstrate mutually exclusive capture and playback.
Thanks, and sorry if the question is irrelevant here.
Do you have any plan to upgare mini_al? It has some API changes and improvements (https://github.com/dr-soft/mini_al/blob/891258a5b0c463ada17c544c438fb6fe6d4f148c/mini_al.h#L13100-L13135)
Hi,
I couldn't find either a document or example of recording from speakers.
Is it possible to do so?
Since I've seen that there's an example on miniaudio git doing the exact thing I have in mind I'm guessing it should be possible. But simply recording from speaker device doesn't work.
Simply passing a pointer to the ID obtained from context.Devices doesn't work, as it always panics at runtime with panic: runtime error: cgo argument has Go pointer to Go pointer. Is there a way to do this?
This library apparently uses OSS on OpenBSD currently, this seems unnessecary. The underlying library supports sndio which is OpenBSDs native audio library. Switching to sndio would mean this would have no additional dependencies on OpenBSD. I believe audio(4) would be preferably on NetBSD also.
Hi,
Perhaps you may find this useful, i am getting the following warnings running enumerate example on m1 macOS 12.1.
It still lists device, these are just warnings.
Thanks

I build with ndk playback.go after renaming package and main method to Run with command:
gomobile bind -o pult.aar -target=android
I got aar and tried to call Run. But I didn't hear any sound. In logs i saw:
AUDIO_OUTPUT_FLAG_FAST denied by server; frameCount 0 -> 1772
How to build on android, it marked as supported os.
I am trying to select specific capture device by setting deviceConfig.Capture.DeviceID but code
var infos []malgo.DeviceInfo
infos, err = malgoCtx.Devices(malgo.Capture)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
selectedDeviceInfo := infos[3]
deviceConfig := malgo.DefaultDeviceConfig(malgo.Capture)
deviceConfig.Capture.Format = malgo.FormatS16
deviceConfig.Capture.Channels = conf.NumChannels
deviceConfig.SampleRate = conf.SampleRate
deviceConfig.Alsa.NoMMap = 1
deviceConfig.Capture.DeviceID = unsafe.Pointer(&selectedDeviceInfo.ID)
produces an panic

Encountered SIGSEGV when trying to execute Uninit() for a device. This happened to me even when I ran the example code in this repository. The recording seems to work as expected though, it's just that I keep getting SIGSEGV every time I want to close/uninit the device.
How to reproduce:
go run _examples/capture/capture.go
Expected outcome:
Successful execution
Actual outcome:

Environment:
I am a bit of a novice to audio encoding. I am attempting to capture desktop audio using WASAPI loopback
Code here: https://gist.github.com/husainhz7/c8d4fac481a3b860243566835afaeca0
I want to feed this audio to libopus to encode an opus stream. libopus requires PCM encoded floats/ints. What is the best way to do that here. I see that miniaudio provides 'ma_encoder_write_pcm_frames' which I don't think is supported by malgo.
Miniaudio recently added experimental support for windows application loopback audio capture to specify/exclude process id
It would be nice to use this new feature in malgo.
Related: mackron/miniaudio#484
Is there any plan to update to Miniaudio v0.9.1? I think there are some breaking changes though.
Hey,
I just noticed that on latest MacOS 14.1.1 (23B81) audio devices no longer show up correctly, only 2 devices available are as below:
Playback Devices
0: 00, NULL Playback Device, [ok], formats: [{Format:0 Channels:0 SampleRate:0 Flags:0}]
Capture Devices
0: 00, NULL Capture Device, [ok], formats: [{Format:0 Channels:0 SampleRate:0 Flags:0}]
It used to work fine on MacOS before, but i cant recall what the last working MacOS version was.
@gen2brain
Hi,
When im running capture example on macos 14.4.1, it doesnt appear to actually capture anything as all the data stored is 0s and there is no mac indicator dot (orange dot in corner) that indicates that its recording.
Any suggestions what i can check ?
I have tried the capture example from miniaudio and it works fine.
I feel like i've had this issue a while back when using this lib, but cannot recall how i fixed it.
Thanks
@gen2brain

Go strings shouldn't normally have null bytes, and this breaks stuff expecting them not to. Normally you convert a C string to a Go string with the C.GoString function, it takes a pointer to a C string and returns a Go string.

@gen2brain could you make a latest tag so we can get the macOS fix in?
Hey! This ain't so much an 'error' but a general usage type of question.
So I wrote a program that is kind of based off of the capture example but using a timer. The source of that program is more or less here.
The parameters I'm passing into malgo look like this:
[Mike]
pollDuration = 5 // Every five seconds, capture one second of audio.
channels = 1
sampleRate = 8000
NoMMap = 1
bufferSize = 1000
Now, the application runs fine and it does exactly what I want it to do - which is to continuously detect whether or not my microphone is capturing audio. However, after probably, like, a few hours of running I start seeing problems from the perspective of other applications. If another application tries to grab control of the mic, then that application freezes up. This occurs even after I shut down my own application.
Is this some sort of locking issues? Am I doing something grossly inefficient? The platform I'm on is Windows 10.
Any and all help is super appreciated.
Hi there, I run into some problems while trying to compile the examples.

It seems that examples don't match the code. I'm not sure... may the examples remain unchanged after updating?
Hi, I am new to miniaudio but since I am looking around for a more complete Go library for audio, I came across miniaudio and your binding project.
From the documentation of miniaudio it appears that there is both a Low Level API and a High Level API, with the latter adding mixing and effects capabilities, as well as a node graph, something that sounds very appealing and much like Web Audio API.
Are there any plans to expose bindings for the High Level API?
Hi,
I am fairly new to go and just made a little binary to pipe the microphone sound to the google speech to text cloud API, it works fine when i do a go run of the code. It also works when i build on my mac machine.
But once i build and notarized the binary to send it to someone in a zip, the microphone input recording don't seem to work when they run the app.
Am i missing something ? Should i be able to build and expect all the included binaries of the plugin to work on the build ?
i feel like it could be related to macOS microphone permission, when i launch the binary there is no prompt to give access to the microphone.
Thanks ❤️
Since release OSX 13.5.2 onwards, OSX CoreFoundation libs et al fail to dynamically link, resulting in no backend beeing opened.
Refer to this issue of miniaudio:
I followed the instructions here and brought malgo back to work:
in file miniaudio.c i added no runtime linking:
#include "_cgo_export.h"
#ifdef __APPLE__
#define MA_NO_RUNTIME_LINKING
#endif
#define MINIAUDIO_IMPLEMENTATION
#include "miniaudio.h"
#cgo darwin LDFLAGS: -framework CoreFoundation -framework CoreAudio -framework AudioToolbox
I will provide a pull request if desired.
