One more feature: have a look at


'Bus 1' has a 1 kHz sinewave at -10 dBFS as input. It has an 'a-EQ'
plugin, with a parametric section set to 1 kHz, -10 dB gain, and
a bandwidth of 1.

The 'Audio' track records the output of 'Bus 1'.

Initial level is OK at -20 dBFS. At 9.5s the bandwidth of
the filter is reduced to 0.1. This should not modify the
output, but clearly something strange is happening. 

At 16s the bandwidth is set again to 1. The actual level
of the resulting burst is around +20 dBFS, that is 40 dB
more than what it should be. In other words, instead of
say 0.1 W, your amplifier will produce 1 kW, assuming it
has that power. Mine will clip at 400 W, still more than
enough to fry the speakers.

If this is representative of the quality of the a-***
plugins (by 'the Ardour Team') then I wonder what to
expect next.



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. (Cory Doctorow)
