Open Source DSP Libraries for Android and/or iOS
5 projects | /r/DSP | 31 Oct 2022

I'm looking for some simple open source DSP libraries in C++ that can do things like delay, flange, high pass filter, etc. I ran across Tonic and Maximilian, but they seem to no longer be active projects and the examples do not compile. Are there any others out there that are truly cross platform and written in C++?

I like KFR very much for its modern C++ interface (14-17). Beware of license, if your project is open it is GPL v2, otherwise you should pay them.
