Lanczos interpolation looks wrong

TF3RDL opened this issue · comments

On FFT mode especially on lower frequencies, the Lanczos-interpolated part should look like this:
musical spectrum of 50hz
where a 50Hz pure tone is played, as shown in a post on HydrogenAudio forum

But right now, it looks wrong (it might display multiple Gaussian-like peaks within very narrow frequency range surrounding actual peaks) as screenshots of this component show

Sorry if I confused you

Which something like this in this component currently:
10 seconds of 50hz tone   foobar2000  13-May-24 5_42_27 AM
