Additional Comments
Expander triangle

Use the recordRate property to trade off between sound quality and disk space when you record a sound.

Value:

The recordRate is a non-negative number.

By default, the recordRate property is 22.05.

Comments:

The recordRate property determines the sound sampling rate when you use the record sound command to record sound to a file.

The possible recordRates depend on the system's capabilities.

The kSamplesPerSecond is the number of thousands of times per second the sound is sampled. The higher this number, the higher the quality of the resulting sound, and the larger the resulting file. For best sound quality, the higher recordRates should be used when the sound input is of high quality--for example, when recording from a CD--and when music is being recorded. (44.1 kHz is "CD-quality".) In general, you can use lower recordRates for spoken words than for music without compromising sound quality.

Note: The answer recordcommand sets the recordRateproperty according to what the user chose in the answer recorddialog box.
