ESS AudioInput & My Soundcard...
Apr 9th, 2008, 7:19pm  
Hi,

I've just switched to using the AudioInput method of ESS for audio-reactive Processing duties (as opposed to loading a wav file), since this is more flexible.

However, I'm having some difficulties getting my soundcard (MOTU UltraLite) to work.

When I run my applet it only seems to respond to the in-built microphone of my Macbook Pro, so it works when I start clapping.

I'm trying to get it to respond to audio from the inputs of my Ultralite (which has a drum machine plugged in to inputs 5+6). What is confusing are the naming conventions of the Ultralite. For instance, on the back of the unit the inputs 5+6 are actually named as 3+4 in software (as 1+2 are the Main Outs to my speakers).

Anyway, I've tried fiddling with the Sound prefs in System Preferences and the MOTU Audio Setup app on my comp.

Presumably I should be able to play something in iTunes too, and by setting my input in the MOTU setup to Mix1+2 it should respond. But alas, nein. Here's a screenie of what that looks like: http://img.photobucket.com/albums/v380/werebunny/MOTUSetup.png

Any ideas? Does anyone use MOTU soundcards?

The type of soundcard doesn't matter, because in OSX it all runs through the Core Audio services.  What you need to do is run the program /Applications/Utilities/AudioMidi Setup.

Using that application you can disable the Built-in mic and set the system to use your soundcard for input.  Any applications using the input will have to be restarted.

I've tried trawling through Sound Preferences and also the AudioMIDI utility application. In the Sound Prefs for example, even though I have my soundcard selected, my Processing app still reacts to the in-built microphone.

There is a bit of included software with the soundcard called MOTU CueMix Console and I have also made sure that "Mix1 Return Inclues Computer Output" is also selected there, and have set my input to be Mix1. In theory this should enable Processing and ESS to react to iTunes.

According to Apple, versions of OS X prior to 10.5 default to mic input, regardless of other settings.

Wow, Apple... thats a pretty serious oversight.  Is it just me or is the Apple QC slipping a little?
