Now let's be clear, we're not trying to put traditional mastering engineers out of business. We don't claim to be better than having an actual human with years of training analyze each second of your track, but we're perceivably close.
Think of us like auto-focus on digital cameras, but for music instead of photographs. The auto focus doesn't make someone a professional photographer, but they sure can take a lot better pictures with it!

a result, they have become the defacto standard for Mastering.
We also support MP3 files for those who don't need such high quality, for example songs you play in the car.
Click here to use our free online Audio File Converter. This tool allows you to convert most major file formats,
ready for mastering. These include WAV, MP3, AAC, AIFF, AU, FLAC, M4A, OGG, RAW and .WMA.
