You would also get more headroom that way. If you wanted a more smoother sound, you would crank microphone preamp gain down and push your fader higher. If you wanted a more open, upfront sound, you cranked microphone gain as much as you can get away with, before distortion, unless that's what you wanted. (In real recording consoles this was a factor on the character of the sound. Lots of negative feedback = low gain and a slightly more squeezed sound. No negative feedback = hi again but more open sounding. It is like an operational amplifier, or Op-Amp circuit. Headchem, the reason why your original is 3db louder, is because you flipped phase and combined both files, causing overall cancellation. According to the iTunes Sound Check, the original file is about 3 dB louder than the distortion removed file, but I don't know how to measure this accurately. Interesting, but I'm not sure there's anything useful here - just a demonstration of the laws of physics.
This clipping sounds like a lot of high frequency energy - what frequencies are most common in digital clipping?įinally, the loud distorted version played with the isolated distortion (inverted) to cancel out the clipping: Distortion Removed=" …"]Distortion Removed The difference between the two extracted by inverting the phase of one of them: Distortion Isolated=" …"]Distortion Isolated The same file will the volume turned up so it clips: Loud Distorted=" …"]Loud Distorted The original material: Original=" …"]Original In case you all are curious, here are the files in mp3 (short fragment of the song): Can anyone explain to me why this didn't occcur?Īlso, can someone try to emulate my experiment to make sure I did everything right? I was hoping that my distortion-cancelled version would sound much louder than the clean version, but without the distortion. The clipping sound from the loud version is gone, but both clean and distortion-cancelled versions sound almost identical. I then invert the phase of the digital clipping and add it back to the super loud clipped version.ħ. I invert the phase on the loud version and adjust the levels until all the shared sounds are phase cancelled, which leaves me with just the digital clipping sound.ĥ. I import them both into a tracking program.Ĥ.
I then exported a quieter version with no digital clipping.ģ. I turned up the final output volume in my mastering chain so loud that it created very noticable digital clipping in the loud sections of the song. I just tried this crazy experiment, and I need help understanding the results.ġ.
