If you count 'instrument' plugins as well things could look different.

And it takes a long time and a lot of effort to build up both the theoretical knowledge and the skills. And even more to understand the practical consequences of some of the standard theory in an audio processing context. It's also a process that never ends. Just yesterday I discovered some small but systematic errors in the white noise generator used in e.g. Jaaa. [*] Anyone who's learning this sort of thing and who uses his/her knowledge to write free software will have my full support. But I won't do anything to make life easier for those who just copy some DSP code and wrap a 'shiny GUI' around it, with as the only result one more that just looks as much as a toy as most of them do. Ciao, [*] Set up Jaaa to measure its own noise output, with averaging. Zoom in on the vertical axis. The result will never be exactly flat (as it is a finite lenght average), but the remaining errors should be random. If you wait long enough and repeat this a few times, you'll notice that the small dips of 0.3 dB or so at around 1, 2 3 kHz are systematic. This was a surprise, as the noise generator is based on a random number generator which has a very good reputation - whatever autocorrelation it hase will probably be insignificant in most applications. Yet this test will reveal them. Will be fixed in the next release of course. -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
