According to AudioUnitProperties.h, the kAUVoiceIOProperty_VoiceProcessingQuality is deprecated. What is the replacement?

 @constant      kAUVoiceIOProperty_VoiceProcessingQuality
 @discussion        Scope: Global
                    Value Type: UInt32
                    Access: read/write
                DEPRECATED. Sets the quality of the voice processing unit. Quality values
                are comprised between 0 (lowest) and 127 (highest).

Try following:

@constant       kAudioUnitProperty_RenderQuality
                    Scope:          Global
                    Value Type:     UInt32
                    Access:         Read / Write

                    A value (0 - 127) that can be used to control the quality (complexity) of the rendering operation. A typical usage is to set render quality to maximum for best quality, but
                    if CPU usage is a concern a lesser quality can be set to trade off render quality.

  • I have also been using that setting as well. But don't think two are related. Do you know what does kAudioUnitProperty_RenderQuality setting do? The default value was 64. I bumped it up to 127. The manual does not seem to be very clear on this setting. – user523234 Nov 05 '13 at 00:05
  • As far as I know you can use: kRenderQuality_Max, kRenderQuality_High, kRenderQuality_Medium, kRenderQuality_Low, kRenderQuality_Min – Aliaksandr Andrashuk Nov 05 '13 at 10:09
