To listen to it on Linux, run:
$ echo | ./bach.sed | aplay -r44100
Or, to play it using sox:
$ echo | ./bach.sed | play -r 44100 -e unsigned -b 8 -c 1 -t raw -
It will take a few seconds (16s on my laptop) for it to start producing sound.
For OS X or BSD systems, you'll have to install gsed
(FreeBSD) or gnu-sed
(OS X) and edit bach.sed to start with:
#/usr/local/bin/gsed -Ef
To install required packages, use:
$ pkg install sox; pkg install gsed # (FreeBSD)
$ brew install sox; brew install gnu-sed # (OS X)
And use this command line:
$ echo | ./bach.sed | play -r 44100 -e unsigned -b 8 -c 1 -t raw -
It should be possible to run on Windows using Cygwin but I haven't tried doing that.
Alternatively, you can listen to the mp3 in this repository or listen here.
