some more Spec questions
...or is used to map an element of the final-floor
vector to a bark-scale frequency, is this correct ?
- The formulas for p and q make use of omega, but there's
nothing in the spec about omega... How is omega related
to [i] or to ([map] element [i]) ?
I can only assume.... omega = map[i]/bark_map_size ?
<p>thanks in advance,
Sebastian

...hesis-stuff:
there's a nice image with bark(x) = atan()... and stuff
Question: What is [n] in the map(i)-iteration ?
I find it a bit confusing because 'n' is used to describe
the length of the spectral-vector to be feed into the MDCT
in the paragraph above.
But the value of bark_map_size seem to make more sense in
this context. (?)
Also, i miss the usage of [i] within the formulas for p
and q. I assume cos(w) = cos(i*PI/n). Is this correct ?
<p><p>thanks for help,
