longDescription = ''
|
||
|
|
This program converts sampling rates of PCM wav files. This
|
||
|
|
program also has a function to apply dither to its output and
|
||
|
|
extend perceived dynamic range.
|
||
|
|
|
||
|
|
Sampling rates of 44.1kHz and 48kHz are popularly used, but the
|
||
|
|
ratio between these two frequencies is 147:160, which are not
|
||
|
|
small numbers. As a result, sampling rate conversion without
|
||
|
|
degradation of sound quality requires filter with very large
|
||
|
|
order, and it is difficult to have both quality and speed. This
|
||
|
|
program quickly converts between these sampling frequencies
|
||
|
|
without audible degradation.
