4. In this example, sounds above the Threshold (-18 dB) are attenuated at an
input to output ratio of 2:1. The compressor does not affect sounds below
the Threshold.
5. Undo the previous operation and select Dynamics again. Now, increase the
Ratio to 7:1 and select OK. The sound will be even more compressed,
meaning that more attenuation and boosting will be applied to compressed
signals.
Too much compression starting at too low a threshold level will usually
lead to a distorted sound.
CHANGING TIME DURATION
Another Sound Forge XP function unique to digital processing is the ability to
stretch or compress the time duration of a sound without altering the pitch.
This is useful for lengthening or shortening sounds to meet a specific time
length.
To change the time duration:
1. Open SAXRIFF.WAV and select Time Compress/Expand from the Process menu.
The Time Compress/Expand dialog will appear.
