Hi
i want to make an app totally similar to this one (which is not yet supported after android api 14)
audioshift.surina.net
www youtube com / watch?v=AGZ7z_OVahU

wich basically is a realtime audio effect, that get the output mix, do some dsp stuff and put the result out.

i reverse enginereed the app and found that they provide a native library, to make their specific implementation of a generic android.media.audiofx.AudioEffect (using TYPE_NULL).
this library i suppose i a slightly variant of the OpenSrc soundtouch.surina.net

so my question is how can i do this modification to the soundtouch library? because in the library is only present a method that operate on samples from file and not from stream.

Thanks
