Audiobook Editing and Mastering – Self-Help Book (ACX Standards)

I'm a self publishing author narrating the audiobook for my own self-help book, roughly 3.5 to 4 finished hours, single voice, UK accent. I need someone to edit and master the recordings once I'm done: cleaning up breath sounds and background noise, levelling, adding chapter silences, and getting the files fully compliant for ACX and Audible. Recording should be finished around October or November, so I'm looking to line someone up now ready for when the files are sent over. This is a one-off project, not ongoing work. Please let me know your typical turnaround once files are received, and confirm you're comfortable working to ACX technical standards. Looking forward to hearing from you. Michael
