[music-dsp] Antialias question

2018-05-31 Thread Kevin Chi
Dear List, Long time lurker here, learned a lot from the random posts, so thanks for those. Maybe somebody can help me out what is the best practice for realtime applications to minimize aliasing when scanning a waveform by changing speed or constantly modulating the delay time on a delay

Thanks Frank, I use cubic interpolation to interpolate between samples and it seems a bit better than linear for me. I am more worried about the downsampling, when the playhead is going faster than the original samplerate and that's when the high frequencies of the original material start to

Thanks for your ideas, I'll look into those! It's actually just a digital delay effect or a sample playback system, where I have a playhead that have to read samples from a buffer, but the playhead position can be modulated, so the output will be pitching up/down depending on the actual

Thank you for the quick ideas, the code looks nice. Currently I am not designing a wavetable OSC, I am just trying to do some basic VA waveforms (saw, tri, square) so naively I thought I just set up the 15-20 tables/waveform  from fourier series whenever I start the app/plugin and that could

Hi, Is there such a thing as today's standard for softSynth antialiased oscillators? I was looking up PolyBLEP oscillators, and was wondering how it would relate to a 1-2 waveTables per octave based oscillator or maybe to some other algos. thanks for any ideas and recommendations in

I just want to thank you guys for the amount of experience and knowledge you are sharing here! This list is a gem! I started to replace my polyBLEP oscillators with waveTables to see how it compares! Although while experimenting with PolyBLEP I just run into something I don't get and
