Re: [music-dsp] Android related audio group / mailing list?

Hi, I do not see drives in the andraudio group since he migrated to [1] Some years ago I tried see how some of my codes works in android, I wrote effects to work in real-time (automatic pitch correction, time stretch, pitch shifters in time domain and frequency domain) and I get a lot of

Re: [music-dsp] Real-time pitch shifting?

A lot of trick but I did https://www.youtube.com/watch?v=YT-zAX3S850 https://www.youtube.com/watch?v=QzVfkgUkLIY Fast Enough... Was fun write the code :-) ♪♫♫♪ ▇ ▅ █ ▅ ▇ ▂ ▃ ▁ ▁ ▅ ▃ ▅ ▅ ▄ ▅ ▇ Sent From The Moon and

Re: [music-dsp] WSOLA

WSOLA is an Time Domain algorithm, Pitch shifters can works in time domain too, there are some ways to do this... WSOLA is just one time-scaler, but you can pitch shift combining WSOLA and Resample: - Change the time using WSOLA (ex. time scale by 2.0) - Use some interpolation(ex. resample scale

Re: [music-dsp] granular synth write up / samples / c++

WoW nice Examples :-) It's really amazing to get satisfactory results without need a pitch track! I will try put some examples in somewhere, I coded some algorithms like Phase Vocoders, TDHS and PSOLA(Lent), I'm using pitch track (AMDF just in monophonic sound) to splice and cross-fade with

Re: [music-dsp] phase vocoder

Some time ago I posted some code in matlab, this is not real-time, you can see the basic math of an standard phase vocoder. https://dsp.stackexchange.com/questions/40101/audio-time-stretching-without-pitch-shifting/40367#40367 This code just change the time, you can pitch shift using a

Re: [music-dsp] Auto-tune sounds like vocoder

When I read the original patent US5973252A (Pitch detection and intonation correction apparatus and method), in the vague description of how the pitch shift is made, I wondered if everything seemed to be as simple as I would be imagining... For pitch shift (auto Tune): Just get the fracional

Re: [music-dsp] SOLA, PSOLA and WSOLA.

In essence WSOLA and SOLA are only for Time Scale Modification... WSOLA - Applies synchronization in the analysis stage of OLA, so input frames are selected based on waveform similarity, keeping the output at a constant rate! SOLA - Works like WSOLA but applies synchronization in the output, so

Re: [music-dsp] Who uses YIN or pYIN for pitch detection?

Pyin seems nice, I never tasted it before ! Yeah I use YIN, I made a sacred way searching and writing Pitch Tracking algorithm to works with Keith Lent Pitch Shifting, I have coded the basic steps of YIN in matlab, but for me or my implementation not works so well like AMDF or some improved
