Hi Paula,   VST's GUIs are diffucult to handle and for me often frustrating to control with mice. I think, VSTs are much liked, because they are free or easy to steal ( or used to be when they came up in the mid of the 1990tees.)   Another question: Were did you hear about MIDI V2?   Rolf

Hi. It's for school project. My project is based on open source code from google examples: https://github.com/googlesamples/android-ndk/tree/master/audio-echo I need to add to this code the WSOLA. That means, implement Filters, and algorithm. I have already filter but I am not sure if it's good.

Alex, may i ask you where you are regarding development on the android?� you're coding in C++ or C (or is it C# or something)? are you at a place where you can make a simple "passthru" app where you can input samples from the ADC and output them to the DAC?� if you are there, can you make a

There are many ways to do real time pitch shift, which one is right for you will depend on things like - what flaws and artifacts you consider acceptable - your use constraints: pitch shift range, granularity et c - processor and memory constraints - the engineering skills and capacity that

It helps if you let us know a) what you've tried and researched already, b) what you plan to use it for, and c) why you think WSOLA is the right solution. WSOLA doesn't have a 'simple explanation and implementation', but if what you want is just some code that does the job and lets you

Hi, All materials and code that I found on google and GitHub have not real time implementation(that means, signal is known in advance) I understand that in this case, I need to do resampling before and after. Thanks, Alex 2018-07-26 3:22 GMT+03:00 : > Not everbody reads mails every day so it
