Hi..
I`m Peter, an experienced /+30yrs/ audio freelancer, working with audio in my own studio.
For projects as "voc-tune" "voc-syncing" I use set of latest professional soft from Melodyne, VocSync and Izotope - it allows me to edit for client top Hollywood quality audios. /incl pitching, create additional harmony vocals from source track(s) getting all synced, de-noised, de-clicked, with eliminated all mistakes as "breath-mouth-lips clicks" and more..
Pls check few audio-examples /custom made, based on projects infos/ in my profile-portfolio demos, illustrating "what I can do"..
from you as source/s/ I need audio tracks as separate, and the best in WAV format + your descriptions -what should be done (if itself problems are not enough clear, from checking tracks)..
/from LOGIC PRO X - you can export tracks to WAV easy way (=save as..)../
let`s chat about it all, and once all is cleared - we can start
