yes i saw. i have a stupid question, why there are 2 chanels in the audio callback ? and what is input and output channel ? if i want to get all the frequencies in a circular buffer, i have to add the both channel in it ?

and if i well understand , there a timestamp of capture in audiooptions ?

Input is from the mic if you're connected to one and output is what goes into the speakers. It's 2 channels because it's stereo but it could be a different number if it's configured for a different number of channels. There is a timestamp so you can keep time even if there's a buffer underrun but it doesn't have true timestamps in environments that don't supply it (like webaudio and openal).

hi thomas, i have some isssue with your audio inout buffer. When i connect to the mic, i have a lot of noise, even when no sound, i have some input in the buffer. How can i filter them ?
'''
private function audioCallbackWithInput(input:grig.audio.AudioBuffer, output:grig.audio.AudioBuffer, sampleRate:Float, audioStreamInfo:grig.audio.AudioStreamInfo)
{
var channel = output.channels[0];
var dataBytesArray:ByteArray = new ByteArray();
dataBytesArray.clear;
for (i in 0...channel.length) {
//phase += 0.1;
//channel[i] = Math.sin(phase) 0.3 + input.channels[0][i] 0.3;
dataBytesArray.writeFloat(input.channels[0][i]);
}
input.clear;
this.callBack(dataBytesArray);
}

@thomasjwebb

What does the noise sound like? Is it just ambient noise or is there any distortion to it?

Or is it harsh digital noise?

brusand

@brusand

i don t know

Thomas J. Webb

@thomasjwebb

Does it get noisier if you clap?

brusand

@brusand

i have some note during some silence (no claping)

how can i send snapshot ?

Thomas J. Webb

@thomasjwebb

Oh you could make a callback collect the buffers and write to a file. I might not have made an example of that. What OS are you in?

And what target?

brusand

@brusand

i am on mac os and send to circular buffer

oki i try to do that

Thomas J. Webb

@thomasjwebb

Oh ok. Tonight when I’m not working for a client I can look at it more.

Good evening every one

@thomasjwebb

Hello

@Gonzzalezz

Sorry, I got it working !

Thanks; have a good night

@jobf

hello hello

I was just trying to get the fm synth examples going again and have made the following changes to bring up to date with AudioChannelData - jamesobfisher/grig.synth@3606dcb

and now I get

SynthChannel.hx:29: characters 28-55 : haxe.io.Float32Array should be grig.audio.AudioChannelImpl
SynthChannel.hx:29: characters 28-55 : ... For function argument 'channel'

jobf

@jobf

oh hm my version of grig.audio was behind - there is no AudioChannelData anymore

Thomas J. Webb

@thomasjwebb

Oh ok. I was going to say I changed it around a lot and I have another branch on grig.audio that’s almost ready to be merged in soon. I’ll make sure to fix whatever that breaks in other repos when I do.

jobf

@jobf

this branch ? https://gitlab.com/haxe-grig/grig.audio/-/tree/refactorAudioBuffer/

I see the cpp redo is coming along too ^_^

Thomas J. Webb

@thomasjwebb

Oh yeah. The cpp redo is actually done. It’s just that I refactored the interface at the same time and it’s that refactor that’s not done yet.

jobf

@jobf

I see

cool stuff

looking at it again I was actually on the cpp branch

jobf

@jobf

looks like AudioChannelData should work but for some reason it's not picking up the target specific implementation here - https://gitlab.com/haxe-grig/grig.audio/-/blob/redocpp/src/grig/audio/AudioChannelData.hx

Thomas J. Webb

@thomasjwebb

Yeah that branch doesn’t compile right now because I’m actively changing the interfaces in it.

I think I want to get it where I can make documentation including multiple targets. I can’t do thar right now because it just uses a different definition of the same classes based on the target so they can’t actually be merged.

So I might make things work more like they do in grig.controller, where I used interfaces.

jobf

@jobf

aha

I've been testing out semmi's peote gui libs - https://github.com/maitag/ - he says hi btw :)

ported my old haxe ui project over to use peote and it's pretty exciting stuff

pure open gl lib across targets

will get something published soon and share :)

Thomas J. Webb

@thomasjwebb

Ooh nice! Yeah his stuff is interesting. It was awesome seeing grig.midi used in a music video. I’ll be sure to work on grig this weekend. I did a lot of work recently using haxe for a bitwig controller script and that took time from my grig.audio fixes.

jobf

@jobf

here is the preview ^_^ https://jamesobfisher.gitlab.io/tnt/

it's very alpha, but it should work, all relies on web audio api for now but the UI can compile cross target

will see if I can port it to grig in due course!

jobf

@jobf

bound keys to track length now so you can go nuts with polymeter

https://gitlab.com/jamesobfisher/tnt/#how-to-use-the-demo

Thomas J. Webb

@thomasjwebb

Nice! I might end up putting some of the synth demos I've made into grig.synth because I actually think the demo fm synth I made is better than the port I did of libfmsynth earlier.

Definitely some cool polymeter possibilities with that.
