It would be nice to have a simple EQ for audio. or better preset EQ and dynamic sounds.

I would also like to see this, phone audio is often very dire as it has such a bad SNR. Some EQ tool to help boost what you want and reduce noise would be very helpful for those who do not have access to proper audio equiptment on a phone or happen to be caught out if the opportunity arises in an unplanned situation.
