Andy will get your track how you want it. There are as many revisions on the mastering process you need. So, if you are unhappy with the first run, we will work on it until you are happy.

Andy began his interest in sound as a keyboard player in local groups. He used samplers, synthesizers and used to record and mix live bands. In the late 00`s he was actively involved as a sound engineer for an Internet-only radio station. Andy’s Dub has charted at No.1 in Beatport and he has had stellar write-ups in the National Press for his Sound Art. An Accredited Member of The Audio Engineer Society, Andy lives in North Yorkshire.

The Studio

I rent a room at Creao Studio. Based in High Harrogate, North Yorkshire, they bring 30+ years of audio, video, media and art’s experience to the table.

CREAO (short for Creative Arts Organisation) is owned by Allan Smyth who has worked in the AV, arts and entertainment industry for 30+ years. Designed by Allan Smyth as a purpose-built feature there is a great sound-proofed room. I am afraid that, due to the nature of the tenancy, I am not allowed to have walk-in visitors for the mastering of audio.

File Format

Stereo WAV or AIFF is preferred - However, we now accept MP3 files too.

Start and End

Leave some air at either end of your tracks.

Reference Track

Reference tracks are welcome. Please send them along with the audio.


Ideally, 24 bit/s.


Please do not brick-wall your track - there is no need to slam the levels.

Sample Rate

44.1 kHz or higher
Use the sample rate of your original session, no gain to up-sample to 96kHz if you’ve recorded at a lower rate. Please, do not normalize.


Please do not fade out or fade in the track yourself - we can be instructed on how to do this, but it could mess up the master if you do it yourself.

Master Bus

If you are using plug-ins on the master bus provide options with and without it. Limiting or clipping the master bus should be avoided.
