Flex sensor and sound

Projects General Guidance
1

Hi!

For my project i was thinking to control sound with a flex sensor. Basically I was hoping to manipulate a pre recorded audio and then, with a flex sensor, change de pitch of the voice on the audio. Do you now how I can do this and, if so, the code?

I don't have the feeling that a 16 MHz Arduino can handle such a level of sound manipulation.

Look at the RPi. It's got the horsepower you need.
