An introduction to how I use Perl to prototype and write software DSP code. Basic operations on signals can be performed without complex DSP frameworks - Perl's pack, unpack, sin, and cos are sufficient for many tasks. Filtering, file type handling, and rate conversions can be done externally by piping data to SoX, "the Swiss Army knife of sound processing programs".
