These are the common questions we get asked every day. Please scroll down for more information.
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.

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.
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:
- 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.
- 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 300MB 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?
Our intelligent algorithms will make your tracks sparkle, but unlike some services, you have full control.
Free accounts can master unlimited low-res 192kbps MP3s for FREE.
If you want to master a high-res 320kbps MP3 or a 24-bit HD WAV, you can pay a one-time $4.99 to master that single track.

What payment methods do you accept?

If you want to upgrade your track or account to get more features, we accept Visa, Mastercard, American Express, Paypal and
Bank Wire Transfers. Contact our Customer Service Team if you need more information.
What audio file format do you recommend for Mastering?
We recommend uploading WAV files for best results. WAV files are lossless so they maintain the full audio quality of the original source material. As
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.
My audio files are in a different format. How do I convert them to MP3 or WAV?
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.
Some of our other audio tools such as the
Audio File Cleaner can also convert file formats during processing.
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 master a track?

Need More Detail?
Click here for more detailed instructions.
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.
Which Interface should I use?
Maztr offers two interfaces: the Simple Interface for ease of use and the Advanced Interface for complete control over the mix.
For the easiest option, choose the Simple Interface where our intelligent algorithms manage most of the decisions for you. However, you may still want to experiment with different
Genres and Intensities for fine-tuning. These preset Genres and settings, based on our team's experience, work for most tracks but serve as broad guidelines rather than a perfect fit
for every situation. You can try adjusting the 3-band EQ or tweak the Intensity, which affects how aggressively our algorithms process your track. For example, lowering the intensity
increases dynamic range. You can also test different Genres since they are simply preset options and might not always suit your track perfectly.
If the Simple Interface doesn’t achieve the desired results, switching to the Advanced Interface offers much more customization and control. You can easily toggle between interfaces at
the top of each project and choose different interfaces for each project, if needed.

I have a Hi-Res Single Track Account. How do I upload more tracks?
You'll need to upgrade to a Pro Account. Hi-Res Single Track Accounts only allow you to master one Hi-Res track.
What devices and browsers do you recommend to use Maztr's services?
While our tools and resources have been designed to work on most devices, we recommend using a computer, laptop or tablet in horizontal mode to get the
best results when using our services. Some smartphones and other mobile devices may have insufficient memory or less capable browsers which may cause
problems during some mastering and file editing processes. For example, if your smartphone "hangs" during processing, it may not have enough memory
and we'd recommend switching to a more powerful device.
Larger screens give more space to perform complex functions and view finer detail. Also, many of our resources are designed to be viewed in landscape
mode, which is a horizontal screen orientation.
Please ensure you have updated your browser to the latest version. Some of our tools and resources use cutting-edge features which may not work in
older browsers. Google's Chrome or Apple's Safari browsers generally give the best user experience on our site. A few browsers such as Firefox have
issues and problems in some situations. Hopefully this will improve with future versions.
How do you calculate MB file size limits for your services.
Our systems use the standard decimal conversion of 1 MB = 1,000,000 Bytes. Please note we use the decimal conversion, not binary.
I don't hear much difference when I master a track. What should I do?
Without hearing your track, it's hard to recommend specific settings, as some sound differences may be subtle and only detectable with an Audio Analyzer. The mastering options for a
track largely depend on the quality of the original mix. In some cases, there’s limited room for adjustments or the mix is already optimized. That’s partly why we offer a
free account option, allowing you to test your tracks in our system before upgrading.
Maztr offers two interfaces: the Simple Interface for ease of use and the Advanced Interface for complete control over the mix.
If you're using the Simple Interface, our intelligent algorithms manage most of the decisions for you, but you may still want to experiment with different Genres and Intensities for
fine-tuning. These preset Genres and settings, based on our team's experience, work for most tracks but serve as broad guidelines rather than a perfect fit for every situation.
You can try adjusting the 3-band EQ or tweak the Intensity, which affects how aggressively our algorithms process your track. For example, lowering the intensity increases dynamic
range. You can also test different Genres since they are simply preset options and might not always suit your track perfectly.
If the Simple Interface doesn’t achieve the desired results, switching to the Advanced Interface offers much more customization and control. You can easily toggle between interfaces at
the top of each project and choose different interfaces for each project, if needed.
I'm having problems using one of your resources. What can I do to fix it?
Unfortunately, it can be difficult to diagnose these problems because there are so many possible causes. Here's a checklist of suggestions that may
help:
- Special characters in filenames such as ( ) # $ % often cause problems. Possible solution – rename files to remove these characters before
uploading them.
- There may have been a connection problem when you were trying to upload a file. Possible solution – try again during a non-peak period.
- There may be an issue with your web browser settings or device compatibility. Possible solution – try a different browser or device. Our
systems generally work better with non-mobile devices. Some smartphones and tablets may have insufficient memory or less capable browsers.
- If you have a firewall, it may be interfering with the process. Possible solution – turn off the firewall temporarily.
- The resource may not have been able to read the data in your files or they're not in compatible format. This may be temporary, so please try
again.
If you continue to have problems, please
contact us and we’ll try to guide you through other possible solutions. For example,
paid users can send us files directly so we can process them manually and diagnose the problem first hand.
