How to master a track using MasteringBOX


In this short tutorial, we’ll show you how to master your track in less than a minute using MasteringBOX…and for free!

To start using MasteringBOX, simply drag and drop your track, or click ‘Master a Track’ to select from your files. For best results using MasteringBOX, we recommend reading the blog post on ‘How to prepare your track for Mastering’.

Once the track is uploaded, click ‘preview’. A 30-second clip of your song will play. You can easily toggle between ‘ON’ and ‘OFF’ to hear the difference between the mastered and unmastered versions.

The most noticeable change is that the track is now louder, but if you listen carefully you can hear that the EQ has also been balanced and the song sounds better overall. On the left, you can manually fine-tune the Loudness with the slider tool. Simply select the desired loudness. If you’re mastering multiple tracks, for say, an album or EP, it’s important to have similar loudness levels across all tracks, but bear in mind that raising the loudness too much can cause over-compression and an unnatural sound on most tracks.

If you have subscribed to one of our premium accounts you can also adjust the EQ with three knobs allowing for Low, Mid, and Hi gain control— superficially similar to a shelving EQ, though the central frequency and Q parameters of each band are dynamically set by MasteringBOX itself, in accordance with the track’s spectral response.

When you’ve finished adjusting, click ‘Update’ to preview the changes and the system will automatically alter the EQ, compression and limiting settings. Optionally, here you can also fill in some information about your track. If you have a premium account this information will be saved in the file data for mp3 and mp4 formats. You can fill in the song, artist, album and composer names, as well as upload a cover image. Crop and adjust your image so it fits right, square images work best. Click ‘Save’ and you will see the updated information for the master.

You can choose the output format you want your audio to be in. If you have a free account with MasteringBOX, you can download one free M4a or MP3 per day. Or you can purchase an individual master in WAV or HD WAV formats for CD and video quality at an affordable price. Simply choose the format and hit ‘Save’ to continue.

You can also upgrade your account to one of our plans! For 6 EUR a month, our Basic account offers access to unlimited compressed M4a or MP3 masters. Also included is the previously mentioned EQ control, as well as the ability to edit your ID3 Tag and upload your Cover Art. If it’s WAV or HD WAV files you’re after, you can get everything included in our Basic plan, plus 3 uncompressed WAV masters for only 9 EUR a month in our Pro account.

Those needing unlimited uncompressed WAV masters should consider our Unlimited plan, for 19 EUR per month. For a Studio or small Label, you’ll need our Studio plan for 39 EUR per month, which gives you the professional license to provide our services to your clients.

Done! Your master is now ready, just click to download it. You can share it with your friends and on social media so they can listen and comment. Click share or copy the URL and post it wherever you like! Plus, if you click ‘View Track’, you can listen to your song on the web player, which displays the cover art and song information we mentioned earlier. You can also edit the master and even master it again for free if you want to make any changes.



This explanation is simple but gives more priorities to PRO members which makes the website less free.


Como podría subir un álbum completo y que el máster aplique a todos los temas en lugar de subir uno a uno?



Yes, you can send us a support message in the support page or you can send us an email to, anyway, replying to your question, you can purchase in the US, the prices are in EURO but you can pay with dollars, PayPal will automatically do the conversion for you.



Is this the only way to contact someone? Well one question. First I LOVE what you did to my mix. I’m excited. But is this available to those of us in US? Is there a US version with Dollar signs and upgrade payment information?

Hi guys, just a quick question: is it possible to simply upload it into my computer rather than being online when I want to master? Help…

I’m so glad I came across MASTERINGBOX I had a good project and they made it so much more’s great..!



Sorry we don’t have that feature at the moment.



When I upgrade can I master all the mp3s in a folder at once or do I have to select them one by one?



You can download the track of course, if you are using Internet Explorer or Safari just right click on the link and select “save as”.



After I master using the web site can I download the track to put on a social website or only stream the music for this site


Gracias por tu comentario. La muestra que se elige no es aleatoria, se elige una muestra representativa, que no tiene porque ser la misma siempre, pero no es simplemente una muestra al azar.
En cuanto a la posibilidad de re-masterizar un tema ya subido, el problema es el espacio que ocupan todas las versiones sin masterizar, aunque quizás se podría activar esta opcion durante una semana o similar, lo tendremos en cuenta.

Thank you for your comment. The sample is not random, we choose a representative sample, that may be different each time.
We will take in consideration your feedback about re-mastering a file, the problem is the storage, but maybe we’ll activate this feature in the near future for a limited time after the master is done, maybe a week or so.


Hace poco hice una suscripcion por un año ya que tras probar las demos en mp3 me parecio muy buena herramienta para masterizar mis trabajos,los resultados son bastante profesionales,tan solo un par de sugerencias:
cuando se escucha la previa donde en teoria podemos modificar el volumen,ese monitoreo es aleatorio ,en mi opinion deberia ser una muestra del pasaje que contiene el volumen mas alto,al ser aleatorio podria ser que despues de procesado y descargado nos encontramos con la sorpresa de que hay pasajes con sobrecompresion ,obligandonos a masterizar de nuevo,y este es el segundo punto:los archivos guardados en la nube son los ya procesados cuando en realidad deberian ser los originales subidos ,porque si una vez procesados descargados y escuchados no nos satisface deberemos volver a subir el archivo original para rectificarlo,que si fueran los originales guardados teniendo una opcion de remastering no deberiamos volver a subirlos ,con el tiempo y el espacio en el servidor que eso representa ;Lo dicho ,una muy buena herramienta


I’m sorry to hear that you don’t like the results, however the mastered file doesn’t exceed 0dB, there’s a limiter to achieve loudness, in fact exceeding 0dB is technically impossible, clipping would occur instead. Please note that some DAWs mark 0dB as clipping, but that doesn’t necessarily mean the file is clipping.


I’ve compared my mastered file and yours. Sorry, but the automatic makes only louder and exceeds the 0dB limit. I can do that too …
