fische 4.0.3

A standalone sound visualization program

Running fische itself is not exactly difficult. Basically you just type “fische” in a terminal and hit Enter. However when you do this, the program quits as soon as it realizes it does not have any data to process. This is normal behaviour.

Obviously, fische needs input data. Data is fed to fische via its standard input. This means you need to pipe it into fische from some program that produces sound data.

fische needs data in 2-channel 16-bit signed integer format. This format was chosen because it likely is the most widely supported one, and also the native format of CDs and many sound cards.

If you can record an audio stream, you can also pipe it to fische.
