| Hello,
I am trying to get started with a very simple Audio Unit that is supposed to control volume. Here is what I have in my processing code:
void TestAudioUnit::TestAudioUnitKernel::Process(Float32 const* inSourceP, Float32 * inDestP, UInt32 inFramesToProcess, UInt32 inNumChannels, bool & ioSilence) { if (!ioSilence) { const Float32 *sourceP = inSourceP;
Float32 *destP = inDestP, inputSample, outputSample, gain;
gain = GetParameter (kParameter_Gain);
for (int i = inFramesToProcess; i > 0; --i) { inputSample = *inSourceP; outputSample = (gain * inputSample); *destP = outputSample; sourceP += 1; destP += 1; } } }
---
When I use this plugin through AULab, I am hearing a distorted sound, even when the gain is set to 1.0. For that matter even if I change the outputSample to be direct (outputSample = inputSample), I am still getting a distorted sound. It goes away when I bypass the plugin.
Obviously, I am doing something incorrectly. I would appreciate any help in finding and resolving this.
Thanks!
