This is the last stop in your production journey. The sound you get from your Mastering Engineer can either make or break your career.
We offer special rates if you only need one song completed. You can save quite a bit of money if you have multiple songs mastered at the same time. This will cut down on your overall cost. A full project (12 – 15) songs usually takes 4 -5 hrs and sometimes shorter if there are no issues with the mix.
We use the finest analog equipment money can buy to provide you with the best sound. There should be no compromise regarding your final sound. We will provide you with both a Wave and high-quality MP3 file of each song. Additionally, if you are creating a CD we can provide you with a DDP file, A DDP file allows the producer and Mastering Engineer to have complete control over all parameters for the CD, therefore it is recommended for critical applications when you have very specific artistic needs for the production. These files have error checking built in. Thankfully most CD plants accept wave files so a DDP file may not be needed.
We can also embed your files with your ISRC codes if required for a nominal cost.
You are more than welcome to send us a sample of your music and allow us determine what is required to provide you with a professional sounding finished song.
