An Overview of Mastering
“Mastering is a science and an art. But, I believe that mastering at its best is also a discussion between the Artist and the Mastering Engineer.
I am here to improve the sound of your music, and I am also here to help you to improve your production & music mixing skills at the same time (Enhanced Mastering, Advanced Mastering, Finish My Song).
I know that you have likely worked for weeks or months on your song, and there are things that you love about the mix and the sound – it is important that these are not lost in mastering, yet you also want to get the extra richness and loudness that mastering can bring.
When we work together, we’ll start a discussion to make sure that the end result you get, is the result you were aiming for.”

Whichever Service You Choose, One Set Of Revisions Are Included in the Price
We will make amendments and send you a second master, free of charge, if you feel that the first master wants tweaking.
Josh’s average turnaround time for masters is 24-48 hours.
Different Edits / Mixes
If you need different versions of your final mix to be mastered with the same mastering processing (for example, an instrumental version of your song) we charge $40 per iteration after the initial fee, above, is paid.
EDM & Dance Music Mastering
For electronic music, we provide two masters of each song. One is a dynamic master (which we recommend you upload to streaming services) and the other is an extra loud master (suitable for the large sound systems in nightclubs and at music festivals).
Album & EP Mastering
We can offer discounts for EPs and albums, just contact us before placing your order.
