Using minclip and maxclip

If minclip <= maxclip , then no sample in the audio data has a value less than minclip, and no sample in the audio data has a value greater than maxclip . The smallest sample in the audio data may be greater than minclip and the largest sample in the audio data may be less than maxclip . These two values do not depend on slope or intercept in any way.

If minclip > maxclip , then the sound sample description specifies nothing about the range of sample values present in the audio data.

If a program modifies audio data in a QuickTime file such that minclip and maxclip no longer bound the range of the audio samples, the program must either update minclip and maxclip , or set minclip greater than maxclip to indicate that the limit information is no longer specified.
