I'm a hobbyist DJ who spent countless hours frustrated by the "E-8304" and "E-8305" errors in the booth as these playback issues were a constant headache and ruined the flow of my sets. I built FixMyWAV to solve this problem for myself and the community, so we can all spend less time troubleshooting and more time mixing. I hope this kept you out of trouble at the decks, happy spinning! :)
