Change Sample Rate
This command allows you to change the sample rate of the document, to change the total duration of the document, and to resample the audio data. When the "Resample" checkbox is not checked, the two fields are linked together since without resampling, the sample rate and the total duration are interrelated. Changing one will change the other. Note that changing the total duration will also change the pitch of the audio, regardless of the "Resample" setting.
The most common sample rate is 44.1 kHz, but you can use any sample rate in Sound Studio. A higher sample rate such as 48 kHz will give better definition, especially in the higher frequencies, but also consumes a larger amount of disk space per second of audio. At 88.2 kHz, a recording generates twice as much data as 44.1 kHz, while going to 22.05 kHz will generate half the data.
