How do I prepare my music for mastering?
  • Mixed down stereo Wav or AIF files in 24bit or higher. No mp3 or other lossy format.
  • Make filenames as short as possible without becoming confusing. 01 Yellow sugar v2.3.wav
  • Your mixes should have a decent level without exceeding 0 dBfs (digital clipping)
  • Don’t use limiters on your master-bus. If you use it to make things louder, remove it!
  • Make sure your starts and ends are OK, so no missing attack or reverbtail
  • Quality check: after bouncing, always listen to the complete track from beginning till end!

I made a dedicated page with way more info on how to prepare your music for mastering, check it out here.

Please read this information carefully and please always double check your mixes by actual listening to it before sending it out.

What is the turnaround time

This depends on a few things. First off all, an album with 15 tracks for cd, vinyl and download will obviously take way longer then just a single track. Second of all, it depends on how busy my schedule is. But useually, a single or EP with a few tracks can be done within 48 hours.

It’s also possible to have same day delivery mastering at a small extra fee. Please contact me first if same day delivery mastering can be done!

Is it possible to attend a mastering-session?

I’m sorry to say that it’s not possible to attend a mastering-session any more. I will explain why I stopped doing attended sessions. I have synesthesia, which means I feel, see, taste, experience music and sound, not just by ear. I make use of this synesthesia during mastering and because of that, the experience drives me in a certain direction to get to the point where things ‘fall into place’. When someone attends the mastering session, I will be distracted and the synesthesia experience will be a lot less. This means I need to listen to it more ‘technically’ and way less by experiencing it, which makes it harder for me to get things in the direction that I want it to. Simply said, it will NOT make your master any better when attending the session.

For albums it’s sometimes a good idea to come to the studio, but mostly for final tweaks, listen to the final masters together or for making the sequence/transistions of the album.

Can you do stem mastering?

With stem mastering individual audio tracks (stems) are grouped together for independent control and sound processing. Sometimes stem mastering can be a lifesaver, for instance, when you have problems mixing in vocals or drums. On the other hand, if your mix is good or just need a few small tweaks in the mix itself, it’s not necessary to work withs stems, it will just get more expensive. I will let you know then with feedback on what to change in the mix. The maximum amount of stems I will work with is 5.

 Most of the times stem-mastering is not needed and will not make your master better. If the mix is good, it’s just a waste of time and money.

Can I listen to some of your work?

Sure! Go ahead and listen to the music in this Spotify playlist. This is a small selection of music that I mastered, but it will give you a good idea. I don’t believe in before/after examples myself because the master will probably be louder then the rough mix and so it will not give you the real picture.

How much does it cost?

For some reason  I get this question quite often. You can check the mastering prices on the .. well.. prices page 🙂

How and when do I pay?

Payments should be done upfront.

I prefer the use of the online order system for regular mastering. That way you can place the actual order and take care of the payment right away using various payment options like paypal, iDeal, creditcard, sofort and many other. In case of an album or specific wishes that will not fit the online order system, please provide me with all name, adress, vat details etc. You will receive an agreed upon invoice and after the payment is take care of I will start mastering.

Can you do a free test-mastering?

I'm sorry, but I don't do any free test-mastering. I will explain why I decided to stop doing that quite some time ago.

With a test-master, it will be a one shot master without any revisions or adjustments. With a regular mastering I will do revisions untill you are 100% happy with the result. Also when we first start working together, it's sometimes searching for the right sound/feel. I sometimes decide to do 2 versions of a first master to start with. With a test-master that will be instantly lost and its just 'a lucky shot'. I believe in long-term collaboration. 

Sometimes people ask for a small snippet of a master, but that might take even longer then doing the full-track.

Besides that, I think, and hope that my portfolio will speak for itself. You can even listen to a selection of some random music I mastered with this Spotify playlist.

If you want an album to be mastered, but you are not 100% sure if i'm the right person for your project, you can always decide to let me work on one track for the regular 1 track fee. We will settle prices for the rest of the album later on.

I don’t like the master, what now?

It could always happen that the master does not sound as you expected. This could be a different vision on the music or you just want it to sound differently. Don’t worry, I will fix that! For me it’s important that you love the master, so please let me know and I will take care of it free of charge (fair use policy). Please provide me with as much info as possible and within 14 days after the initial masters.

Mastering is great, my mix is not, what now?

It could happen that in some kind of way you missed out on something in the mix and of course you now hear that back in the master. You are responsible for the mix you deliver and you should always double check your mixes by actual listening to it before sending it out. Because of the analog mastering, it’s not just a matter of open the new file, click bounce and done. Everything has to be set up again (hardware doesn’t have a save button) and needs to be re-recorded, saved, quality checked etcetera. And that is when the same settings can be used again, a new mix will probably also need some adjustments. All in all, pretty time consuming.

Depending on the situation I will charge extra for that. Please contact me and we will discuss the solution.


I  get quite a lot of questions about ISRC codes and UPC/EAN codes. To make things more clear I made a dedicated page with info on how to get codes and how to use them. You can find the info right here.

I want it LOUD!

Even though more and more people realize that squashing music is not the way to go, I still have to explain to some people about the consequences of overly loud masters. That is why I decided to make a dedicated page about loudness in music.

I need Vinyl ready masters

As a vinyl freak (I collect vinyl and turntables) I know my way around vinyl pretty good! Even though I don’t cut vinyl masters/lacquers myself, I know quite a lot about vinyl and so I know exactly how to make masters that will translate good on vinyl. I also know the right directions for pointing you to the right cutting-engineer and pressing-plant.

There is a maximum of audio which can be cut to vinyl and even though they are just rough numbers, they will give you some guidelines to keep in mind.

12 inch @ 33RPM: Optimal 16 to 20 minutes, max 25 minutes
12 inch @ 45RPM: Optimal 6 to 12 minutes, max 15 minutes

I need official Apple Digital Masters

Da Goose Mastering is a certified Apple Digital Masters provider (formerly know as Mastered For iTunes) so please ask me if you need Apple Digital Masters. ADM masters are free of charge when provided stand-alone, I charge a small extra fee when provided next to regular masters.  Read more about Apple Digital Masters here.

I lost my masters, please help!

All of the masters that I do are backed up in various ways. It’s backed up to my raid5 NAS system and that is synced once a day to a secondNAS with RAID system. Next to that, once a day everything will be pushed into the cloud to save things on a EU based cloudserver.

I get quite a lot requests to upload masters again because people don’t backup and loose their files.. Even though I’m not, I feel responsible for that and I don’t charge it but in exchange, I want people to donate money to The Ocean Cleanup or another good course.
