[Stk] RtAudio - Problem with RTAUDIO_SINT24

[Gary Scavone]

Hi Thomas,

The RTAUDIO_SINT24 is defined as the upper 3 bytes of a 32-bit signed integer.  So, you should be able to play it as 32-bit data.  I made it that way for convenience, since there is no "native" 24-bit variable format in computers.
