Soundtoys EchoBoy - Manual (Page 17)

Non-Real Time Processing (AudioSuite)
If you want to save DSP power, EchoBoy can also be used to process a specific region of audio
destructively. This is done in Pro Tools using the AudioSuite version of EchoBoy. To do this,
first select the region of audio you’d like to process from the Edit window of Pro Tools. Then
choose EchoBoy from the AudioSuite menu of Pro Tools.
Hit the process button to process the selected region with EchoBoy and to write the result back
to disk. To hear the effect before committing to disk, click on the preview button.
Echo Boy Mono vs. Stereo Operation
EchoBoy provides both Mono and Stereo plug-ins for use on mono or stereo track inserts or
busses. If you are using EchoBoy on a stereo insert (or processing a stereo region with
AudioSuite), the processing will be TRUE stereo. This means that if you use EchoBoy in a stereo
mix bus what ever is coming out of the left side will have a delayed version appear in the same
location as the input signal with the same being true for the right side, middle etc. The delays
will appear where ever the input signal appears in the stereo mix.
The only times this is NOT true is in Ping-Pong and Rhythm Modes. In these modes the left and
right channels are summed to feed the input of the delay. The output of course remains in
stereo so you can hear the ping pong, cross channel delays etc. Otherwise the ping-pong effect
would be lost, as these require that the input be mono and the output be stereo.
