Small bug in ATK FOA Decoder Psycoshelf

[gsenna]

Hi,

Should line 94 of the ATK FOA Decoder Psycoshelf read as

wc = tan($PI * mFreq * inverseSamplesblock);

instead of

wc = tan(pi * mFreq * inverseSamplesblock);

?

Thanks!

Hi,

Thanks for the quick reply. Another issue seems to be that the filter becomes unstable depending on the samplesblock used. 128 works, but with values like 256 and 512 the amplitude blows up.

I set up a new issue #78 to address the instability, and close this one.
