PROCESSING AUDIO CHP. 10
Release threshold
Determines the threshold level for detection of the trim/crop end point: -Inf. indicates complete silence, and
0 dB indicates maximum amplitude level.
Fade in
Determines the length (in milliseconds) of the fade applied to a section of audio prior to the detected trim/
crop start point.
Fade out
Determines the length (in milliseconds) of the fade applied to a section of audio following the detected trim/
crop end point.
Minimum inter-phrase silence
When you choose the Remove silence between phrases function, the Minimum inter-phase silence value
determines the minimum amount of silence needed between phrases for a new region to be created.
Minimum length following loop end
When you choose the Remove data beyond loop points function, the Minimum length following loop end value
determines the number of samples that must follow a loop.
Bit-Depth Converter
The Bit-Depth Converter is used to increase/decrease the bit depth of a file while concealing the resulting
quantization noise.
• Decreasing a file’s bit depth decreases the overall size of the file, but results in added quantization noise,
which can be masked using dither and noise shaping.
• Increasing a file’s bit depth—while not improving the quality of the audio—allows subsequent audio
processing to be performed with greater accuracy and resolution.
Prior to decreasing a file’s bit depth, you should optimize the audio for conversion. For more information, see
Minimizing quantization error on page 86.
Note:
There are no rules regarding maintaining audio
quality when decreasing bit- depth. For this reason, you
should always experiment with the
Dither and Noise shaping
controls to determine the optimum settings for each file.
