Re: [LAU] Top DSP plugins?

The two issues are related. The FFT based EQ in Jamin uses a form of block processing that leads to a filter that is not time-invariant, it produces AM on some frequencies. In the first release that was very obvious, you could actually hear it quite easily. Instead of changing the algorthm to a correct one (which would be quite similar) the Jamin devs chose to mitigate the effect by increasing the overlap between successive blocks. IIRC there are now 32 overlapping blocks at any time. This reduces the modulation to acceptable levels, but is also what is responsible for the high CPU load. A correct implementation of this type of EQ requires an overlap of half the FFT size, so it would require much less CPU.
