>You're powering your op-amp from 0-5V
yes, it is lm324n, i don't think it's rail to rail but that doesn't matter, since the sine amplitude is only like 1V and i am only interested in top half of it (i want the op amp to remove the negative bottom half) so it should be well within spec of it
here is the exact setup i am using
i just cannot figure out why the fuck does the sine go flat when i connect the audio signal to the op amp input, it makes no damn sense
