Re: [PD] frequency shifter
if you could help me with the math required, i would be very grateful. I think what they're talking about here (single side-band modulation) works this way. We take our original spectrum which has two sides, each the conjugate of the other. /\ /\ ___/\/_\|/_\/\___ we get rid of one side, to get the complex representation /\ __|/_\/\___ In the time domain this is a complex valued signal. To shift all the frequencies by a certain amount we convolve in the frequency domain by an impulse given by the fourier transform of e^(2*pi*i*f) where f is the frequency to shift by. This looks like, in the frequency domain: | __|__| Convolution in the frequency domain (with a single sided spectrum) shifts all the frequencies to the right. Conv. in the frequency domain is the same as multiplication in the time domain. So we can do this operation as complex multiplication of our two complex signals. Resulting spectrum /\ __|__/_\/\_ Then, just throw away the imaginary part and multiply by two, and there you have a real-valued signal.

[PD] grump moratorium
I was just chatting about the pd list with David Merrill, and he brought up a good point. Basically, some of the sarcasm and grumpiness will surely scare away many newbies from this community. As a sometime grump, I would like to call for a grump moratorium. Of course, I can't expect a complete lack of grumpiness and sarcasm, so I think it can be regulated by a simple rule: only be grumpy or sarcastic to people you have met in person. Just my two bits... .hc Looking at things from a more basic level, you can come up with a more direct solution...

Re: [PD] frequency shifter
If all you want to do is generate two different simple waveforms that are shifted 175 and 224 Hz from the original, I would simply use two more triangle oscillators in place of the pitch shifters, and set the frequencies using a bit of math based on the frequency of the first triangle oscillator. I suspect this diagram could represent a hardware synth, where three oscillators is about the max you can get without a huge modular system. Digital pitch shifting uses either FFT or other windowed procedures which sometimes doesn't always transpose a sound that smoothly and without some artifacts. best, d. hard off wrote: in the following picture: http://www.soundonsound.com/sos/Mar02/images/synth4.gif how do i make a frequency shifter ? is this the same as the pitch shifter that i can rip from the pd docs, or is there a simpler way?? -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 201: "What were the branch points in the evolution of this entity?" ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
