After spending all this time making timelapse movies, I had to make some timelapse audio. I wrote a simple script and here are a few samples of the output:
ELP live at the middle east. 60 minutes compressed to about 1 minutes:
A conversation with Bill and Jamie that went from 40 minutes to about 1.5 min.
A performance of Handel’s Messiah from the Brooklyn Pentacostal church (missing the famous ending). About 70 minutes down to 1.5 min.
How do they make you feel? They correctly convey the feelings of being there but don’t really reveal too many details? I will continue to experiment with versions of this. Play with timings, mixings, etc.
This was a shell script implemented with SoX, a free and open source audio toolkit. Download for free from http://sox.sourceforge.net. It requires a little bit of UNIX/LINUX know-how but is pretty straightforward. Check the attached SoX README file on installing the separate LIBMAD and LAME for dealing with mp3s.
Here is the script:
The script calls on another script you can get for free from the SoX page as well:crossfade_cat.sh. edit the $SOX line in this file to point to correct location. varies slightly on mac/linux distros.
