Small wonder. The equaliser alone will pretty much max out the Ipod CPU,
depending on which codec you use. Adding more will certainly not help
the situation.

The only thing you mention which grabs RAM is the database. The other
three just use CPU power. The most hungry of them is the EQ with all
five bands enabled. Dithering and crossfeed are about equally intensive.
We hope this CPU problem will be dealt with better when we can use the
second CPU core in the Ipods.
