Basically, I’m trying to build an Android app that will take a stream voice signal from the mic and adds some effects to it (like a voice changer app. so as you speak your voice will be pitched down for example).

so, is there any tutorial on how to do that using fmod ?

thx

Yes, please take a look at the [record](http://www.fmod.org/documentation/#content/generated/example_lowlevel/record.html) example we ship with FMOD.

This example shows recording from the microphone and applying a DSP effect to it with live playback. You can swap the DSP effect out for any other effect you desire.

EDIT:  
Our examples run on all platforms, in the case of Android this is via the NVidia integration. Also we have information in our [docs](http://www.fmod.org/documentation/#content/generated/platform_android/basics.html) showing how to compile FMOD using the NDK toolchain. For use with Android Studio you would need to adapt our NDK example.

Hello, I am testing the record case now, but the numDrivers returned by the getRecordNumDrivers method is 0. How to solve it?
