This program checks reading and writing a large amount of 24-bit
|
|
audio data to an AIFF file.
|
|
|
|
This program serves as a regression test for a bug in the Audio
|
|
File Library in which requesting more than _AF_ATOMIC_NVFRAMES
|
|
(1024 frames) from afReadFrames when reading a 24-bit audio file
|
|
would result in corrupted audio data.
