                      2:  * recordfiletest - use the sound library to record directly to a file.
                      3:  * This example records from the codec microphone, but note that using
                      4:  * SNDStartRecordingFile() is especially useful for high sample rate
                      5:  * recording from the DSP.  Also note that when recording from the DSP, the
                      6:  * dataFormat of the resulting soundfile must be changed to a playable format
                      7:  * (like SND_FORMAT_LINEAR_16) before it can be played back.
                      8:  *
                      9:  * The use of SNDAlloc() causes virtual memory to be allocated, but since
                     10:  * samples are written directly to a file, this VM is never touched.
