I was just able to create a Bounce out of Ableton that goes 2-3dB above full scale — are those all intersample peaks?
Getting an extra 1–2 dB on a master can make a big difference, and many say they "like the sound" — but isn't that partially dependent on the sound of the clipping in the DAW (what clipping algorithm is used), and then partially reliant on the D/A converters that have to figure out how to translate those peaks to analog signal (which could be different for every listener's device)?
im also on Ableton live (11.1.6)
i tried the following experiment:
-load up a drum loop and turn up the gain to +6db on the fader, the master fader goes well into the red on the master fader
-make sure no plugins are on the master fader, limiters compressors etc
-export the loop to wav
-start a new session in Ableton, drag the previously exported loop into Ableton
-look at the waveform and see that a huge ammount peaks are squared off at 0dbfs, and there is really harsh digital clipping
-play the loop and check the peak meter on the master fader
-peaks at a maximum of +0.05dbfs
those +0.05dbfs are intersample peaks
I have no idea how you exported a file that can then be reimported and show a peak of +3dbfs -- it literally shouldn't be possible.
feel free to upload an exported wav file that peaks at +3dbfs, I'd love to see it.
regarding a "clipping algorithm" afaik, there isn't one, if a sample is +2dbfs in the daw, it just gets exported as 0dbfs, which results in a squaring off of the wave form.
"and then partially reliant on the D/A converters that have to figure out how to translate those peaks to analog signal" -- yes the d/a needs to handle the intersample peaks, but if you have a load of 0dbfs sample points in a row, its just going to sound like 0dbfs -- really nasty clipping.
I would personally just get a good peak limiter and smash it to 0dbfs and turn off "protect intersample peaks" if you wanted to maximise your output. fab filter pro-l has that option. most clubs have decibel limits and, most dj gear has auto volume correction, so that's something to think about also.
limiters like the pro-l can be pushed into limiting distortion which many people say they "like the sound", but no-one likes the sound of digital clipping.
