CoreAudio's AudioStreamBasicDescription structure problem

Hey there,

Does anyone know how to set the format of CoreAudio’s: AudioStreamBasicDescription structure in ASOC? I’ve just started a project using CoreAudio and Accelerate with an autocorrelative algo and I want to use CoreAudio’s buffers so I can use an instance of mData.

I’ve tried…

use framework "CoreAudio"

set audioFormat to current application's AudioStreamBasicDescription's new()

But it doesn’t like the “new” message.

Thanks in advance!
