tremelo effect

Postby Arduinoob » Mon May 12, 2014 11:29 am

Im trying to understand the tremelo effect, and maybe use my own wavetable, but the waveform that I made is very noisy. I understand I use the sinewave table to generate the tremelo LFO, I think the difficulty is at the multiplication between the input and the LFO.

did you create your own wavetable? what does your code look like? what did you change from the example?

I just replaced the sinewave header with a square wave header. Im trying to create a ring modulator.

can you post a snippet of your lookup table, showing both some of the positive values, and the negative values? also, is it the same length at the sinewave table?

also, square waves have a lot of harmonics in them, is the noise you mention "noise" like white noise? or is it distortion/clipping? does it repeat at the LFO rate?
