Fun with AU Lab

Posted on 28 September 2009 by Johannes Fahrenkrug. Tags: Cocoa

The speech synthesizer and the AU Lab application might be hidden gems on your Mac! Why not have some fun with them?

Here we go:

Download a long text file, for example this one.
Open Terminal.app and run
```
say -n : -f 28500-8.txt
```
The "-n" option will redirect the speech output through AUNetSend.
Open /Developer/Applications/Audio/AU Lab
Click Next, Next, Done.
Select "Edit" > "Add AudioUnit Generator..."
Select "AUNetReceive" from the Generator drop down and click OK.
Click Connect. You should hear the book being read.
Now play with the different effects in the "Effects" drop down in the "Output 1" section. AUBandpass, AUDistortion and AUMatrixReverb are fun.

Have fun!
