Friendly Guidelines

All files must be appropriately named. (VERSE / HOOK / BRIDGE / INSTRUMENTS ETC) 

A-Grade cannot guarantee our maximum quality if the  engineer has no direction of what they are mixing as 30 %- 60% (average) of mixing time will go into organising your files instead of actually mixing .

Labelling appropriately helps us to do our job to make YOUR work as amazing as it can possibly be.  

Please ensure you upload in WAV format

For mixing and mastering this dramatically affects what level of quality an Engineer can achieve from a song

Please use ZIP folders for stems 

This makes sending simple and easy as one file. 

Please ensure that your tracks are not clipping (distorting) 

As a matter of quality control, if we feel your recordings are unfixable, unfortanetly we will be unable to accept your work in good conscious as it is not honest to guaruntee the industry standard on work in which it is impossible to achieve. If this is the case you will naturally be refunded and given support on how to get better recordings immediately. 

How to upload export your songs in Logic 

Not a logic user ? Thats ok. Simply go to YouTube type "how to export stems for" and include the name of your Recording Software (DAW).
