The Ghost in the MP3

Post by Pitch Black » Thu Mar 12, 2015 11:15 pm

So, someone took what's left out when you convert a file to a 128k MP3. In this case it was Tom's Diner by Suzanne Vega - interesting because that was one of the tunes used when the MP3 format was being developed.

Video and Science-y stuff

Whoa.
Who put Evostick in my DMT ?

That just triggered me into a flashback, and a simultaneous flash-forward. I am experienceding a whole lifetime as a meta entertainer in a parallel future-now until my untimely death from fractalised prefrontal lobe syndrome from imbibing too much metameaning.

It was OK. It was good. Skull became detatched.
Some damage occurred

Interesting.

It sounds quite different from what I get when I do Tarekith's trick, which is to put the WAV and the MP3 on parallel tracks, and then phase-cancel.

It would be cool to turn this into an M4L device. One which does some bit-reduction and then gives you the missing information back in its own channel.

If you think MP3 is bad try listening to a 128Kbps pcm wave file. (eg 8 bit 16 KHz mono)

And I'd like to know how much gain was applied to the difference track to make it audible?

Also don't forget this is an mp3 of the differences and so different from the real difference. :)

You don't need M4L for that. just place a Utility and a Redux on parallel chains in an effects rack.

I tried it. It gives some well weird sounds when you tweak the "downsample" knob, but the bit depth knob just seems to produce hiss.
