Fun with AU Lab

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