Audio manipulator

This project involves the making of a board the can edit audio live. Primarily the board consists of three components which will be described briefly below.

FPGA

When doing live changes to audio, it is important that the hardware is fast enough to handle a continous audio stream. An FPGA is a very fast kind of computer where the user has better controll over its hardware, thus increasing the possibilities of what we could do with the sound.

Audio Codec

The audio codec simply receives the sound signal and feeds it to the FPGA and then spits the changed sound back out again.

Microcontroller

The microcontroller is a very small computer which mainly is there to make sure the audio cadec has the right settings.

Result

The end result unfortunately didn't work very well as the edited signals became heavily distorted. The reason for this is still unknown, but could hopefully be solved with a little extra time of tinkering!
