As I can see from your code, in the "audio.vhd" file, you are storing the data in "AUD_DACDAT" to send it out to the D/A Converter for headphones. Before doing that, you can invoke your filter. It should be fairly simple. I have modified the "audio.vhd". You can see the changes I have made under the tags "CHANGED". I did not compile it but it should be able to do what you ask.
