Normally when DSPing users would want headroom a few db away from 0 dbfs. Was this only an issue that appeared when users were walking the line at the point of clipping?
I believe the changelog is referring to a fix for this longstanding bug:
There currently seems to be an issue with Roon’s phase inversion feature, whereby any clipped samples are ‘wrapped around’ and instead of just clipping at positive 0dBfs, will go to negative 0dBfs, creating significant distortion.
This can be audibly demonstrated very easily by playing a track with samples at 0dBfs, or that contains intersample overs.
If you listen to ‘Bon Voyage’ by Droeloe ( https://song.link/gb/i/1170076107 ) and then enable phase inversion as shown:

Then just li…
It is/was an error in the DSP code that caused samples at 0 dBFS to wrap around from the positive half of the waveform to the negative half.
