问题 I want to record audio with Superpowered SDK on my rooted Android Q device. As Google has put some restrictions on recording Audio on Android Q so I am trying to port Superpowered SDK Android Example into a Linux executable that I can run on system space bypassing the Android Apps restriction. Please let me know if I am wrong at this point. For this I have created a simple project with the main class as the following: #include <string> #include <OpenSource/SuperpoweredAndroidAudioIO.h>

How can I make it happen, that the SuperpoweredAdvancedAudioPlayer

Superpowered: real time pitch shift with timestretcher not working

由 断了今生、忘了曾经 提交于 2019-11-27 07:24:06
问题 I am using Superpowered for various real-time FX and they all work very straightforward. However the pitch shifting is a whole other story, I think in fact because it's based on the time-stretching algorithm that of course has to deal with output that changes in time which is a lot more complex than applying FX like EQ or reverb. However I'm only interested in change the pitch of my mic input. I looked at the only example I could find on GitHub and I slightly adapted it to fit my work: static
