Frequently asked questions / General info

What is the mastering process?

Here is a list of the main tasks we will do during a normal mastering session:

  • Balance harmonics
  • Spectral correction
  • Control dynamics
  • Optimise loudness
  • Add analog warmth
  • Give coherence to an album
  • Optimise for playability on all media

Here is a list of other tasks we do depending on the project and customer requests:

  • Adjust stereo width and add ambiance
  • Edit flaws
  • Adjust length of silence between songs and PQ points
  • Insert Metadata
  • Apply noise reduction to eliminate clicks, pops, hum and hiss

What is Mastered for iTunes (MFIT)?

Audiomaster is an Apple certified MFIT provider, we can provide a master that can be labeled Mastered for iTunes (depending on your aggregator or distributor capability).

MFIT in short:

When creating a master, mastering engineers take into account the limitations and characteristics of the medium or destination format, as well as the listening environment of their audience. We follow Apple’s guidelines  as to provide a master that is optimised for iTunes (and as test have shown a MFIT master will in general sound better on all media).

We have found that a true mastered for iTunes (MFIT) master should allow around 1db of headroom to avoid digital clipping. In this regard however, we need to mention that depending of the medium you use to distribute your music you will have to provide one wav file that will be sent to all online shops or streaming services without regards to the mastered for iTunes guideline. Although we strongly recommend that the MFIT guidelines be followed for all release, please let us know and we will adapt the master so it sounds optimal for all medias or provide an extra master that will peak higher than the MFIT master.

For you to check the MFIT quality we will send you the preview in AAC format for you to judge for yourself and compare with your favourite artists.

For more in for please read the mastered for iTunes page:

How to pay?

We will send you an invoice at the same time as the final master file, you pay only when you are satisfied.

What is the waiting time?

Depending on the amount of work ongoing we are usually able to deliver single tracks and EPs within 24 hours to 48 hours and albums anytime within 7 days. In any case we’ll keep you informed if we are in a busy period but do let us know if your project has a crazy short deadline, we can probably make it happen without the stress.

What is the free test master?

It’s a real master of 1 track as we would normally do except that it’s free and that we send you the master available for streaming in high resolution 24bit 96kHz.

How to prepare your mixes for mastering ?

Please do not over compress or use any limiter on the final mix unless it’s for tonal purpose.

We advise that the sound files you send do not peak above -3db but You can normalise to 0db if you want, we will level the sound to our needs.

What format should i send the mixes to be mastered?

We accept .wav and .aiff files of a minimum resolution of 16bit 44.1 kHz.

We recommend a bit depth of 24 bit and a resolution of minimum 48khz , ideally 88.2, 96khz or above.

for MFIT the minimum resolution is 24 bit 44.1khz

Please do not upsample the files and please do not send MP3.

How many revision/recalls can I get?

You can ask for as many recalls or revisions as you want.

Our experience is that our customers are generally satisfied with the first or second master and we rarely do more than 4 or 5 recalls but we want you to be 100% satisfied so you can ask for as many revisions as you want regarding any aspect of the master.

What happens if I am not happy with the master?

If you are not happy, get back to us and we will make the changes required for your satisfaction.

In the extreme case you really don’t want to go further with us, simply let us know and we will refund you if you have already paid.

Can you insert IRSC codes and metadata?

Yes of course we can add the irsc codes and metadata to the DDP, simply add the codes to the order form or email them to us later if you don’t have them yet.

what file upload/transfer method do you use?

We use wetransfer and fidbak for file transfer as we find it the easiest and fastest for our service, when you submit the form you you will be redirected to the wetransfer page automatically so you can transfer the files to us.

However you can use any method you prefer use dropbox or google drive If you prefer this method let us know.

Do you review mixes?

Yes we can review mixes free of charge, no problem, just send us the file!

We asses the mix on the first listen and we actually would rather you go back to the mix if any element of the mix is out of place than try to correct the impossible with the mastering process.

What is a Stem Mastering?

Usually, if you ask us to review your mixes you will not need a stem mastering.

Stem Mastering is a method of mixing audio material based on creating groups of audio tracks and processing them separately prior to combining them into a final master mix. Stems are also sometimes referred to as submixes, subgroups, or busses.

Basicaly we would use in general 4 stereo stems (for example: vocals, drums, bass, other instruments) and we would mix and process them ourselves before creating the stereo master.

This technique can be useful if a mix sounds muddy for example or if an album has been mixed by different engineer or recorded in different studios.

We have found that some of our customers can struggle with their final mix down quality and like to leave it to us to make the final decisions to optimise the mix down and create a cleaner master.

Can we work with this genre of music?

We do not specialise in any genre of music or type of project, Over the years we have worked on many projects and an extensive range of genres, if you are unsure try the free test mastering service or please get in contact with us.

Reference songs?

We recommend you send us some reference songs so we have an idea of the loudness, tone and dynamics you are looking for. In the event you don’t send us any reference we will master the song so it is ready for release, sounds modern and fits within any playlist of the same genre.
