Re: PT mixer headroom severely reduced to 20dB over 0dBFS. Bug?
I just tested this and any method of increasing the gain above +20dBFS results in the distortion. Clip gain, Audiosuite gain, and real-time plugins all get the same result. The only way this doesn't happen is when increasing the gain above +20dB using the mixer alone.
I was able to see the distorted wave we're hearing by using the gain Audiosuite plugin to increase the 80hz tone +30dB in a floating point file and then decreasing it 30dB again. The end result should be the perfect sine but instead there are a bunch of tiny sawtooths.
