Hi..
I`m Peter, experienced audio-freelancer-composer-sound editor + more.. I work in my own audio-studio, at professional software from Audition-Cubase-Vegas-Sonar-Melodyne-Izotope and more including dedicated tools for doing mix and all postproduction works..
Please send me your sources /when ready/ (to get best quality of mix - in non compressed format as wav), as well your details about "how you want" to get it mixed, list with sequence of your sources it should be mixed.
you wrote about "looping it" - it is no problem with wave files - it loops perfectly, but by mp3 format, by looping it - you `ll get small audible "gap" by replay - I have special dedicated tool to eliminate this problem, and create "mp3 without gap"... I can add this extra edit for FREE..
let`s talk to fix all, and let start..
