Audiobook Editing - Post Production

Audiobook post production is the procedure that turns your narration recordings to a final audio product - audiobook for your audience. It contains stages like noise removal (plosives, mouth clicks, crackles and other), polishing the overall recording cutting unwanted frequencies and resulting to a cohesive flow in terms of audio level so your audience would not need to turn up or turn down their device volume if there were significant rises and falls of the level. The main audiobook platform ACX has some audio submission requirements that must be satisfied 100% so your audiobook would be delivered through the online retailers ACX work with.
