Change sample rate
Use this function to change the sample rate of a whole audio file. This may be needed to convert a DAT
recording at 48 kHz to 44.1 kHz for use on an audio CD.
After choosing the new sample rate you can select a file name for the new project.
If the resolution is increased the sample rate change will take place without any quality loss, and the
sample material will not experience fidelity reductions, but the required hard disk space will increase.
If the resolution is reduced, then the overtones or high frequencies may be lost during the sample rate
change. For example, if the resolution of a 44.1 kHz sample is reduced to 22.05 kHz, the frequency
response of the resulting sample is reduced to 11.025 kHz. The frequency response is always half of the
resolution specified. For a conversion from a 48 kHz sample to 44.1 kHz, this loss in quality is not
significant, since the human ear only recognizes frequencies up to 20 kHz. (A resolution of 48 kHz is
often only used because the digital to analog conversion can take place with much higher precision
without a lot of effort.)
Please note that resampling to 44.1 kHz can also be done while recording in real-time.
The "Playback parameter" window ("P") contains a "Vari-speed" option for real-time resampling during
playback. The "Record" window ("R") lets you resample to 44.1 kHz in real-time from any of the
selected sampling rates.
