Can you Make it loud?

If no specific notes are given, I’ll make a master to a level that fits with the style of the supplied source material and is consistent with modern norms.
If requested or if required, I can make masters louder.
If you ask for this, please consider:
Digital audio has a ceiling. By raising the level you’re also increasing distortion and sacrificing some of the dynamics. There are a number of techniques that I can use to make this process more flattering, but ultimately it’s still a destructive trade-off.
It’s also worth noting that during broadcast the audio will likely be fed through another chain of limiting  and compression, If your master is excessively loud prior to this stage it can make these artifacts more noticeable.

What Formats do you accept?

I can accept your audio as: 

  • any Wav/Aiff equal or higher than 16 bit, 44.1 kHz.
    (Mastered for iTunes requires 24 bit minimum)
  • 1/4 inch analogue tape.
  • 1/2 inch analogue tape.
  • DAT.
  • Cassette.
  • CD/DVD

I do not accept:

  • Compressed formats- MP3, M4a, AAC etc. unless a lossless codec (flac, ogg) has been used. If the only available files are compressed, please make me aware of this in your session notes.

    Please read the preparation guidelines page for further information.

It depends on the project you are proposing, If it’s a single track from an album I’d likely say yes.
It also depends on my workload.
Example tracks are limited to download only.

What are UPC/EAN and ISRC codes?

International Standard Recording Code.

ISRC codes are used to identify recordings and ensure that royalty payments are made if material is broadcast, streamed or purchased through an online distributor. They can be embedded into the lead in portion of a CD.
Each track is given it’s own unique 12 character identifier in the form;


country coderegistrant codeyeartrack number


different recordings, edits, and remixes of the same work should each have their own ISRC.
Click here for information on where to obtain ISRC’s in your area. More FAQ’s here.

Universal Product Code / European Article Number

UPC or EAN codes are unique barcodes used by retailers to identify products in a physical or digital format.
Two barcodes should be acquired if the recording is being distributed in both physical (CD/Vinyl) and digital (download) formats.
EAN/UPC can be obtained through your aggregator.

iTunes and other computer based players do not read CD-Text. Track metadata is retrieved from from the Gracenote online database
If you have a CD drive that is capable of reading CD-Text you can use the Terminal Command line application to display it.
In the Terminal type “drutil cdtext” (without the quotes) and it will display all of the CD-Text and other metadata on the disc.
If the Gracenote media database has no information for a CD, you can enter the song information in iTunes and then send the information to Gracenote so that others can see it.


      • Make sure you’re connected to the Internet.

      • Choose the CD from the Library pop-up menu.

      • Enter the song information.

      • Click Gear icon with an arrow pointing down and choose Submit CD Track Names.

      • Click on The CD options menu Enter the artist and album information and click OK.

Please ensure that when you listen to the stems summed together it is exactly as you intend the mix to sound without clipping. Files must have the same starting point.

You can… There are plenty of reasonably priced, high quality digital tools available.
However, if the purpose of creating your own masters is to compensate for any discrepancy in your monitoring environment (especially relevant in home studio) You would be in a better position to do this out-with the room with the problems. To verify them, you would need to check your masters on numerous playback systems. This is a process that takes a lot of practice to perfect.
A faster, more effective way to deal with this is to send the record to an engineer who is specialised in this process. He/she hasn’t heard the songs hundreds of times, can utilise a purpose built acoustic space with high quality signal path, identify problems by listening and return consistent masters in a timely fashion.
Whether you think the service is worth investing in depends on how much value you place on your time and whether as an artist you have time to invest in developing these skills.

I accept most major credit and debit cards.
Bank transfer and Paypal payments are possible.
Online payments can be made in the client area.
