Who is Maztr?

Maztr was established in 2016 by a group of audio engineers and musicians who saw the need to help the home recording artist master songs and podcasts in the cloud — For FREE. Our intelligent algorithms can make your track sparkle, but unlike some services, you have full control. Check out our latest video to get an overview of our service.

Maztr is for recording artists everywhere. Create and be free.

What is mastering?

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. It is the final set of tweaks before music is released. Click here to find out more.

Why do I need mastering?

Mastering can make your tracks or podcasts sparkle - more like the songs you 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.

Does Maztr really work?

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!

Can I try Maztr before I buy?

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

Are there any commitments?

Nope! You can change or cancel your Plan at any time. No contracts, no commitments.

Do I need a credit card?

Nope! You only need a credit card if you'd like to upgrade to a paid plan or upgrade a track to download a 24-bit WAV. There's no credit card needed to use the Free Plan to master MP3s.

What Plans do you offer?

We offer 4 types of plans - Free, MP3, Pro and Pro Plus - each with different features.

Each paid plan also offers monthly and yearly payment options. Please scroll down for more information.

Can I change my Plan?

Sure can! You can change your Plan or downgrade to a free account at any time by clicking on the "Plan" option in your account.

Please note, if you downgrade, we do not offer refunds on payments already made. Also, to keep our costs low, all masters from your paid account will be deleted.

Can I master just a single track?

Yes, sign up for a free account and master a low-res 192kbps MP3 for FREE.

If you want to master a high-res 320kbps MP3 or a 24-bit HD WAV, there are 2 options to master a single track:

  1. If you already have a free account, click the "Upgrade Track" button in your Project to get all the Pro Plus features for your chosen track.
  2. If you don't have an account, click here to jump straight in and master a Hi-Res track. This option allows you to master a track up to MB in size with all the Pro Plus features.
Both options cost a one-time $4.99 fee to master that one track.

Can I master 16-bit WAVs?

Yes, Pro and Pro Plus accounts can master unlimited 16-bit WAVs as well as 24-bit HD WAVs and high-res 320kbps MP3s. Upgraded tracks also have these options.

What quality are your masters?

Can I remaster my old MP3 music library?

Sure can! Many of our customers use Maztr to refresh their old music tracks from decades past and make them sparkle. In particular, MP3 tracks ripped from old CDs can get a new lease of life when you run them through Maztr's intelligent algorithms. Our MP3 Accounts are perfect for this purpose.

Can I resell masters I make?

You can! You can do anything you'd like with the masters you make with Maztr. We only charge you for your membership and retain no rights to your tracks.

Do I have to credit Maztr on my releases?

Not at all. We'd love it if you did :) , but no one has to know you used Maztr.

Can I stream and share my tracks?

Yes, Pro Plus Accounts can have their own public web page and playlist for every track and project. You can also upgrade a single track to access its own public web page.

To set this up, just enable web pages in your track settings. Click here to find out more or click here to see examples.

How do I download my completed masters?

On a computer or laptop, you can download a mastered track by right-clicking on the MP3 or WAV button, then select the "Save Link As…" option.

If you have a Mac with a 1 button mouse, Control-Click the MP3 or WAV button and select "Download Linked File". Also, you can hold down the option key when clicking the button to download your mastered track.

The process is a little different on mobile devices. In Chrome, long press the relevant button then select "Download Link". In Firefox, open the relevant file in Firefox's player, long press on the player then select "Save Audio".

How do I change the settings for a track I've already mastered?

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.
