Ghosts in the Mp3: What's lost when a track is compressed

Discuss.

""moDernisT" was created by salvaging the sounds and images lost to compression via the mp3 and mp4 codecs. the audio is comprised of lost mp3 compression material from the song "Tom's Diner",
famously used as one of the main controls in the listening tests to develop the MP3 encoding algorithm.
Here we find the form of the song intact, but the details are just remnants of the original. the video was created by takahiro suzuki in response to the audio track and then run through a similar algorithm after being compressed to mp4. thus, both audio and video are the "ghosts" of their respective compression codecs. version one."

wow.

It's real nice, love spectral artefacts - reminds me of the album by The Automatics Group: Summer Mix

Sounds great

Wish he kept it raw tho. It sounds like he added/tweaked/composed a bit on the track. Shouldn't that chime be all grainy and stuff? Or am I mistaken?

But I guess Vimeo compresses the audio/video too, doesn't it?

yes you're right. LaserDisc is the only true way that this can be viewed without nulls.

You'll never truly witness anything unless you can shoot lasers out of your eyes

I like the resulting audio, but using it to denigrate the mp3 format is misguided. "Listen to everything you're missing!!" Sorry but psychoacoustics (and the psychoacoustic models used in lossy encoding) do not work this way.

Current, optimized implementations of mp3 (i.e., lame) achieve perceptual transparency at reasonable bitrates (below 192k); any doubters out there can go ahead and try ABX a lame-encoded VBR mp3 of their favorite music vs the uncompressed original. The fact that the mp3 standard is old is irrelevant.

VST plugin version of this pls

convert track to mp3, import & invert phase?

Very cool idea - sounds awesome!

awesome!

I've gotten a similar effect in Audition by running the noise remover on extreme settings before. Didn't turn out quite this abstract but it had that same eerie digital spectral sound. Very cool.

Coninidentally it looks like the album I talked about up there ^^ yesterday has just got a repressing. This time on 12'' - http://boomkat.com/vinyl/1218175-the-automatics-group-summer-mix-vinyl-edition
