Local music gets its own ambient soundtrack of the day

A couple days ago we wrote about the Justin Bieber song "U Smile" that a producer had taken and slowed down into a half hour of smoothed-out ambience, and that everyone seemed to enjoy quite a bit. So we tried it on some local music to see if we could make our own.

The program that accomplishes this is called PaulStretch, written by Paul Nasca, who

NPR took the time to interview

and have explain the workings of his program. Here goes:

"The idea of it is pretty simple. I take a small chunk (usually around 100 milliseconds) of the audio file from the start position, and I smear it: first I analyze a sound's frequencies, and then randomize a part of the sounds characteristics and rebuild the chunk. I repeat the same process for another chunk of the audio file, and so on."

These "smeared chunks" (those numbered segments in this image), are then placed next to each other to elongate the track.

So instead of simply stretching the entire song, the stretches occur in tiny increments. When they overlap, they create a cohesive body of sound.

It seems that this time neither the singer nor the DJ, but instead the programmer, deserves the artist's credit.

Except that last point: I really think I did a bang-up job on these, so...

Chelsea Boys, "Track 5" (from their new record) 6.6X Slower

Gay Beast, "What You Want" 3.1X Slower

Dark Dark Dark, "Colors" (Tom Inhaler Remix) 5.2X Slower
