Hi Roni,

kAudioUnitProperty_RenderQuality is a valid property to set on AUVarispeed for 10.4.7. By default, it is set to maximum quality. It is likely that older versions of AUVarispeed don't support this property, and in those cases you can safely ignore the error (setting it will just have no effect).

Note, however, that you cannot currently set the render quality property on an AUVarispeed unit after it has been initialized. This is a known bug in Core Audio.

Hi,

I'm using the AUVariSpeed and I have it working fine.

One question:
Should I set the kAudioUnitProperty_RenderQuality property?
Doing it under 10.4.7 works fine (at least it doesn't return any error) but under 10.2.8, it returns error -10879 (kAudioUnitErr_InvalidProperty)


Here's what I do?

	UInt32 quality = kRenderQuality_Max;

 	// set quality
	UInt32 propSize = sizeof(quality);

	theErr = AudioUnitSetProperty(
							mConverterUnit,
							kAudioUnitProperty_RenderQuality,
 							kAudioUnitScope_Global,
              0,
              (void *)&quality,
							propSize);

	if (theErr != noErr)
		return theErr;


Is there any quality setting to set for AUVariSpeed? if there is, what's the default setting?
