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.

Bit-Depth Converter dialog

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.
