Mastering is the final step of audio post-production. The purpose of mastering is to balance sonic elements of a stereo mix and optimize playback across all systems and media formats. Traditionally, mastering is done using tools like equalization, compression, limiting and stereo enhancement.

Mastering can make your tracks or podcasts sparkle - more like the songs your hear on the radio. It is usually done as part of post production. Most people will hire a mastering engineer even if they record in a nice studio. Maztr makes this service instant and affordable.

Sure does :) Sign up for a free account and try it out for yourself.

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!

Sure! Just sign up for a free account, master some of your tracks and upgrade when you're ready.

Sorry no. To keep our costs low, all masters are deleted from your account when you downgrade. You will need to upload your tracks and master them again.

When you upload a track for mastering, our system processes it using the settings you have chosen at that time. If you want to change those settings, you need to remaster your track to apply the new settings.

If you have a free account and don’t have remaster access, you need to upload your track again with the new settings to apply the changes. Alternatively, you can upgrade that single track or upgrade your account to get remaster access.
