Is ofxAudioUnitRecorder functional?

[jasonlevine]

Hey Adam,

Just set up some code to record some timelined aumus but nothing is being recorded and I'm not getting any error messages in the console. Please let me know if I'm hooking my AUs up incorrectly or if ofxAudioUnitRecorder is just not functional yet.

Here's my signal chain:

    kit1 = ofxAudioUnitSampler('aumu','CaC2','CamA');
    kit1.loadCustomPreset("kit1");

    kit2 = ofxAudioUnitSampler('aumu','CaC2','CamA');
    kit2.loadCustomPreset("kit2");

    bass = ofxAudioUnitSampler('aumu','CaC2','CamA');
    bass.loadCustomPreset("bass");

    drone1 = ofxAudioUnitSampler('aumu','CaC2','CamA');
    drone1.loadCustomPreset("aqueous_ripples");

    drone2 = ofxAudioUnitSampler('aumu','CaC2','CamA');
    drone2.loadCustomPreset("aquatic_undertow");

    mixer.setInputBusCount(5);

    kit1.connectTo(mixer, 0);
    kit2.connectTo(mixer, 1);
    bass.connectTo(mixer, 2);
    drone1.connectTo(mixer, 3);
    drone2.connectTo(mixer, 4);

    mixer.connectTo(recorder);
    recorder.connectTo(output);

    output.start();

and here's where I try to record:

    if (key == 's') {
        recorder.startRecording("j2xsoundtrack");
    }

    if (key == 'x') {
        recorder.stopRecording();
    }

Thanks man,

Yepp, that should work, but you'll need to specify a .m4a, and also give it an absolute path.

So recorder.startRecording(ofToDataPath("j2xsoundtrack.m4a"));

Let me know if that does / doesn't work, though.

Aha! solved. Yet when you save an aupreset you don't set an absolute path or add the file extension. I think one way or the other should be consistent across the addon to simplify usage, unless there is a specific reason otherwise. What do you think?

[admsyn]

Yeah for sure, it'd be a breaking change though. The "absolute path" thing is showing ofxAudioUnit's roots as some non-OF code I had written for myself.

FWIW there's two methods for the presets, one explicitly asking for an absolute path + file extension. Still inconsistent, though :)

[jasonlevine]

gotcha. Anyway, just made an awesome video soundtrack with ofxAudioUnit
and ofxTimeline! So much cooler than using ableton or cubase or whatever....
