You can't provide integer to most audio units on the desktop - you
have to provide float32 - so your "IsSigneInteger" flag is wrong.
In CoreAudioTypes.h there are also some definitions for the linear
PCM flags for native, canonical formats, so have a look through
these... You can also get the format first from an audio unit and
have a look at what its default is and use that as a starting point
Thanks for the advice. I tried the flag kAudioFormatFlagsCanonical,
but the EQ unit still yielded kAudioConverterErr_InvalidInputSize
I then called AudioUnitGetProperty to get the the
kAudioUnitProperty_StreamFormat from the EQ unit, then I'm even more
puzzled... the reading was this:
The number didn't seem to add up (shouldn't bits/channel be 16 in this
case)? I must have wrong understanding of how EQ unit works or what it
expects as input, but I don't know what goes wrong...
