Hello,
in System Release 2.0
    SndMusicDSP/Reference/02_Classes/SoundKit/Sound.rtf

the Instance Method
    convertToFormat:samplingRate:channelCount:
is described:
    Convert the receiver's sound to the given format, sampling rate,
    and number of channels.  An error code is returned.

I dared to use it:
    err = [theSound convertToFormat:SND_FORMAT_LINEAR_8
			samplingRate:SND_RATE_LOW
			channelCount:1];

Now I get always err = 21.
Finally in <sound/sounderror.h> I found:
    SND_ERR_NOT_IMPLEMENTED	= 21

If this error code is always returned by convertToFormat:..., would it not
have been better to write in the Reference

    convertToFormat:... is not implemented?

j.k.
