Convert sample rate
This function allows you to change the sample rate of a recording. This is
very convenient if you have a file that you wish to use in a certain audio
system and find that the file was recorded at a sample rate this system
doesn’t support. Please note that Sample rate conversion can also be
done as part of the Saving process (see “Saving in another format (Save
as…)” on page 117).
Please note the following:
• Sample rate conversion from a low frequency upwards does not improve sound
quality. The high frequencies that were lost due to a low recording frequency can-
not be restored by a conversion.
• When you sample rate convert down to a lower frequency, high frequency mate-
rial will be lost (this is part of the mathematics behind digital audio). Therefore, do
not convert down and then up again, since this will lead to a degradation in sound
quality (unless that’s exactly what you’re after). Instead, use the Undo and Redo
functions.
Performing the sample rate conversion
1. Select Convert sample rate from the Process menu.
This opens the Sample Rate dialog.
2. Select the desired sample rate from the pop-up menu and click OK.
If you want to change any other audio properties (e.g. the bit resolution or stereo/mono sta-
tus), you can do this in one of two ways:
