In the "Data format" tab, you can select the sampling rate and a channel. "22050Hz" and "Mono" are generally used, however, a greater sampling rate can be selected when higher quality sound is required. Please note that some sampling rates cannot be used with some compression systems. Both 22050Hz and 44100Hz are generally supported. A lower sampling rate will reduce the quality of the audio, but also reduces the amount of storage space required.
