Mastering: How to prepare & send files ?2019-05-30T14:05:32+00:00

​Guidelines for submitting a pre-master:

If you have done your own rough/home master, you can also include it in the package. Export it before proceeding with the instructions below.

• We recommend turning off all compression, multi-band compression, EQ and limiting on your master channel before the bounce/export. However if you have processing on the master that you think is part of the ‘sound’ you can leave it ON.

• Ensure the headroom on your master channel is at a minimum of -6dB and not peaking/clipping over 0dB at loudest parts of the track.

Export/bounce settings:

Format: WAV
Sample Rate: 44.1 KHz or higher (if your project if at 44.1Khz please do not choose higher rates at the export)
Bit Depth: 16bit or higher
Dithering: OFF
Normalise: OFF

• Please name your track using following format: ’Artist Name – Track Title’, i.e. Chris Guy – Rock It

You can use Wetransfer.com to upload the file(s) and send us the link to [email protected] We also accept files from other file sharing websites such as Onedrive, Google Drive, Dropbox, pCloud, etc.

If you have any questions or get stuck at any point, please let us know and we will be happy to assist.

Mixdowns: What is a stem ?2019-05-30T14:07:09+00:00

A stem is typically an individual track in the project bounced to Wav later at the export. However a Group can be also a stem, if you decide to export it as one track. We offer different stem packages, the more stems you are submitting, the price will be higher.

Please remember the more stems we have access to, the more impact it will have on the final result.

If you’re unsure which package to choose,  drop us an email at [email protected] for free mixdown evaluation and we will advise which package would be the most suitable.

Mixdowns: How to prepare & send stems ?2019-05-30T14:07:14+00:00

Before exporting stems, please export the full song as you would normally do. It’s fine if you have processing on the master channel, please leave it turned ON and include the exported file in the stem package.

IMPORTANT: Please leave all processing and automations you have on your stems turned ON. You are welcome to additionally send the unprocessed/raw versions (they still need to include automations), but please put them in a separate folder.

​Typically for a basic 10 stem package, you would split your song into stems listed below. For bigger packages, just use the same formula, but strip down further the groups listed below into individual stems:

Example of a 10 stem package:

1. Kick
2. Bass
3. Snares/Claps
4. 4×4 Main Hat
5. 4×4 Main Clap
6. Percs
7. Tops (hats / cymbals / shakers / tambourines etc.)
8. Keys, Chords, Pads
9. Synths, Leads
10. Buildup & Transitional FX (white noise / filter noise / crash / hits / impacts)​

Please don’t forget to load stems into an empty project and check carefully for alignment, levels, automations and make sure there are no missing sounds. Length of the stems need to match the total length of the song.

NOTE: We offer step by step guide for each DAW on how to export and prepare the stems, so please don’t hesitate to send us an email specifying your DAW software and we will walk you quickly through the process. Following the guide guarantees the best results and error free process during the export.


We offer 10% discount if you are sending 2 songs and 15% if it’s 3 or more songs. All songs need to be send as one email submission in order for the discount to apply.

I need additional radio/club edit2018-12-13T00:24:35+00:00

Additional edits of the same song are chargeable at £10/edit.


Will I keep all royalties and copyrights?2020-02-01T01:01:53+00:00

All tracks can be used for broad commercial use and there is no need for reporting or payouts to the producer. You own the master of the final recording. For both Fully Engineered Tracks and Additional Production you will keep 100% royalties from sales.

When it comes to registration of the song with companies that deal with publishing, such as PRO/PRS/APRA/GEMA etc. normally for Fully Engineered tracks you will share 50% of publishing with the producer. There is an option of a ‘buyout’ (you keep 100%), please get in touch about this. For Additional Production, usually we will not claim any royalties/publishing however on some more complex jobs that involved arranging, restructuring, or generally tasks which resulted in significant alteration to the original idea, a negotiated split with the producer might be needed. 909 Studios reserves the right to feature some jobs as part of company’s portfolio. Engineering and Additional Production jobs will appear as ‘mixing’ and ‘additional production’ credits.

How long it will take?2018-12-13T00:01:46+00:00

Projects are sent out Monday – Friday between 5pm – 6pm GMT. We are closed during weekends and bank holidays.

We do not commit to hard deadlines for Additional Production / Engineering, since those services are based on creative alterations to your music, which can take a lot more time then mixing/mastering. Finalisation of the project also depends on how quickly client responds to feedback, some people prefer to take some extra time with the track etc. Every project is evaluated on individual basis depending on what’s required, therefore the turnaround time will be different for each track.

But to give you a general idea, Track Engineering from scratch would take around 2-3 weeks. Smaller jobs such as additional production (such as sound replacement, layering etc.) would typically take 2-4 days.

How to send files?2018-12-12T23:23:14+00:00

If you’re sending us your track for evaluation, you can either upload it to Soundcloud (please make it downloadable if possible) and send us a the link, or use Wetransfer.com .

For stems submission  you can also use Wetransfer, or other file sharing websites such as Google Drive, Dropbox, pCloud, sendspace, etc. and email us the link to [email protected]

We look forward to hearing your music!

Terms & Conditions
Mixing doesn’t involve creation of new sounds, adding delays or big reverbs that would creatively change the track or influence transitions between sections. It also doesn’t involve arrangement changes, audio editing or removing audio material etc. (if you would like to discuss these, please send us an email regarding this matter). However we allow 1 simple revision free of charge, that involves audio editing and 1 stem replacement / resubmission if needed.

​Any additional revisions of that nature will be charged extra (starting from £5 depending on complexity of the tasks), since they are not part of the mixing/mastering process. So please make sure you are happy with the arrangement before submitting the project for mixing.

Sometimes we ask clients for mixdown amendments in order to get the best results at the mastering stage. This may delay the delivery in some cases, depending on when the revised track has been re-submitted (we will inform you if any delays will occur).

NOTE: Errors in stem submissions for mixdowns may delay your delivery and incur in additional charges, so please make sure to follow carefully the file submission instructions.

Why Mastering?2018-11-26T04:43:08+00:00

Mastering process is the last stage in music production. It means bringing the song to the industry standard RMS and peak volume and preparing it for the distribution for particular media. Quality masters will make your tracks stand out more and can potentially increase the sales and chances to get your demo noticed by a record label. Mastering engineers will make sure your productions have sufficient dynamic range, warmth, and will be transferable to other soundsystems.
