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
error on page 103.
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.
Converting a file's bit depth
1.
Open the Musicbed.pca file.
2.
From the Process menu, choose Bit Depth, and then choose Bit-Depth Converter from the submenu. The Bit-Depth Converter
dialog is displayed.
3.
From the Bit depth drop-down list, choose the desired bit depth.
4.
If necessary, use the Dither drop-down list to specify the type of dither used to mask the quantization noise results from lowering a
file's bit depth. For more information, see
5.
If desired, use the Noise shaping drop-down list to specify any noise shaping to be applied to the file. For more information, see
Noise shaping on page 177.
Note:
When increasing a file's bit depth, set the Dither and Noise shaping controls to None and Off respectively.

Description
When you choose the Remove silence between phrases mode, the Minimum inter-phrase silence value
determines the minimum amount of silence needed between phrases for a new region to be created.
When you choose the Remove data beyond loop points mode, the Minimum length following loop end
value determines the number of samples that must follow a loop.
