Zero latency and FFT plus inverse FFT is impossible. So striving for zero latency and claiming to be some application of FFTĪfter one time window sample has elapsed the processing can at most start. On a normal CPU this latency will always increase by threads and CPU load. Video conferencing always a limiting factor.īy splitting the signal in small short time windows,Īnd applying some signal processing on each of these frames you get what you want. Most CPUs has the FLOPS required to do what a special purpose DSPīasically latency is for most practical applications like gaming or It is much better we agree about what DSPs can do, I was there many many years ago and I have seen an introduction Meanwhile I have discovered some nice pages I have previously

I'm still learning how to use all features. I will take a close look on Audacitys FFT Filter.
Which could have taken hours to weeks in a traditional studio.Īudacity's FFT Filter and the Equalization effect Tcp/ip and use a massive beowolf cluster of say playstations to calculate effects in near real time, say 200 ms, You could use your guitar with a wlan antenna and transfer the guitar audio acoustic output to What audacity does in a sound engineers studio could even be implemented and done on stage in real time, Which you can even program yourself, if the manufacturer gives you the specs. Some engineers and programmers are a little bit old fashioned and still only use FFT but it is most likely possible to do a lot more, An example of an analog signal processor is the moog synthesizer.Īnything a moog can do your guitar plus a DSP also can do, you don't really need FFT for that, The main applications of DSP are audio signal processing, audio compression,Īnd many more, tracking filter for preventing feedback, acoustic feedback,Īnother application is to sing and then in real time get your voice translated to sound like Elvis Presleys voice, Then I need to know more about the DSP digital signal processor used in the equipment, The more interesting question is what it does, In most cases it is only used as a marketing gimmick. The FFT is a special case of the Fourier transform. You have in signal processing, the laplace, the fourier and the z transform. I know what most of the features are in the Effects drop list, but I have not been able to find much about FFT filters. It's a classic case of old dog/new tricks. Rasely wrote:I am a guitarist/composer attempting to create my own demo recordings. This can give you musical tone controls on steroids and caffeine. Normally, this would take, like, a bazillion years to do on a musical composition, but FFT is a tool that makes certain assumptions and restrictions and greatly reduces the amount of work that the computer has to do. If you have a flute and an oboe playing the exact same note, how can you tell them apart? Overtones, right? Fourier is the science of predicting with mind-bending accuracy exactly why the oboe sounds like that and writing down, with a tiny pencil on a really big legal pad, exactly what and where each overtone is. I'm not totally sure what the difference between those two tools is, but I know FFT made most modern audio tools possible. Pull the work window bigger and bigger to get more and more accuracy. Both have a "rubber band" line that you can drag around to get different effects. Note that the FFT filter is a cousin to Equalization.
