Previously the chain function was working sample frame based. In each cycle it
was checking if it is time to run a fft or if it is time to send a message.
Now we changed the data transform functions to work on a block of data and
calculate the max length until either {end-of-data, do-fft, do-msg}. This allows
us also to avoid the duplicated code for the single and multi-channel case (as
the transformers have the same signature now).
This is a simple, rather lame spectrum analyzer made from the fix_fft.c code, as found I think in xmms-0.9.1 (the 75-wide output sounds like xmms to me), which is actually written by other people (see fix_fft.c for credits). It worked last time I had GiST working, which was a while ago. Yes, GiST is not included here yet, it will be in 0.1.0.
