I wasted two hours reading the sox documentation and searching on the web for the format of some obscure fscking sound sample, and then finally came up with this. This plays only the first three seconds of your unknown formatted sound file using every one of sox's built-in filetypes. If you don't get an exact match, you may get close.

.

I could not fit every single type in and keep it under 127 characters, so you will have to replace "..." with the full list obtainable by `$ sox --help` (or try `Show sample output`)

.

note: /usr/bin/play should be linked to sox on most systems.

useful signals are:

pkill -SIGSTOP mpg321 #pause pkill -SIGCONT mpg321 #resume pkill -SIGHUP mpg321 #stop pkill -SIGKILL mpg321 #force exit

TIP: use aliases or shortcuts to control mpg321 from the Desktop Manager

This command, taken from play's manual page, plays a synthesized guitar tone for each of the strings on a standard tuned guitar.

The command "play" is a part of the package "sox".
