Mastering audio is the final stage of audio production. Read more about mastering and online mastering.

Nowadays almost every mastering studio offers online mastering services. Read about how it works at Red Mastering Studio.

Ordering at Red Mastering is really easy. All you need to do is to complete and SUBMIT a Job Order via CART for the service you require, and you will be able to make a payment via bank transfer (free/no fees! if you are UK based, for USA citizens and EU based Clients, there is option to pay via Transferwise (you could pay in your original currency, therefore saving on exchange, as we have bank accounts in USA, Australia, Europe). That transaction is also the cheapest one on the market, less then 1% fee. The last option will be to pay via Stripe (the most popular, safe, and secure payment), which is also the most comfortable, as it will be done entirely from within our page)

1. Your mix should be created in the same frequency your project has been mixed. If you have mixed in 48kHz or 96kHz, do not convert to 44.1kHz. Do not convert your mixes/files to 44.1 kHz or to any higher resolution as it will only add zeros and won’t change audio quality.
My advice
 – always record and mix at 24 bit resolution. Even if you have recorded at 16 bit, mix it at 24 bit to give plugins more headroom.

2. Do not use any effects such as limiting, heavy compression, clipping, etc. on you stereo output track. If you really like the sound of your mix with them on, please send two files – processed and unprocessed.

3. Make sure that there is no digital clipping on your individual tracks and on the final mixdown. Make sure that at the highest peak the song does not hit 0.0 dB fsd and if it does, drop the level few dBs and bounce it again. I would advise to leave anything between -12dB to -3dB fsd of headroom, especially if you work with 24bit mixes.

4. Please send one stereo file rather than two mono tracks.

5. Deliver your mix in WAV or AIF file format. No mp3 please! MP3 is a lossy compression format, therefore quality and fidelity suffers

6. Zip your file before uploading it to

You do not need to have a Stripe account to pay for Red Mastering services. You can also pay using a valid credit or debit card. All payments are secure and protected by Stripe. Or if you choose direct transfer via your bank or Transferwise – it’s all safe, reliable and convenient. We have chosen this new way of payment after being with Paypal for almost 15 years, their services recently went downhill, to the extent, that Ebay is parting with them.

It is a technical checkup and review of the client’s mix. The client will receive a report with pointed out mistakes and suggested changes to make the mix sound better.

It is very helpful and beneficial to the music – small changes during re-mixing can improve the final master dramatically.

I normally advise to take the Mix Review option. However, a Mix Review report won’t teach you how to mix. If you are not an experienced mixer, you may not be able to apply the suggested changes to your mix and the Mix Review will become a formula you don’t know how to apply. Please bear that in mind when ordering.

Delivery times have been updated in our new service. We decided to give Clients much more choice, depending on their requirement and budget. Now you can save some money when ordering any service, simply choose longer delivery time, if you are not in rush. Delivery time starts from 10 days delivery (cheapest and longest time of delivery) up to 48h if you have an urgent work to be done. (most expensive) Please bear in mind when changing time of delivery, final price will change too. The exact date will be shown on your Job Order/CART. You can always change it.

We understand the music business, being there for many years. If you need work to be done within weekend (as a standard we don’t work during weekends) or you need work to be delivered 24h, please get in touch with us and we let you know if we can do this for you. This obviously will cost extra.

Accordion ContenMix Feedback, is our new service, you can choose Mix Feedback when ordering Audio Mastering for each song).

It literally is a few sentences comment on mix provided by client. The difference between Mix Feedback and Mix Review is that Mix Feedback is delivered always, after initial master, just a comments to the quality of the production and mixing. Where Mix Review is delivered BEFORE mastering audio, plus there are comments about how and what can be done (by the mixing engineer) to improve the song. Client get the email with comments (MIX REVIEW) and work on improving the mix, and then send new one for master. Mix Feedback, is an information about what was wrong and what was good in your mix, it can give you some extra information about quality of the mix, therefore you can improve it in the future.

Yes, there is. Mastering for vinyl needs a slightly different approach than mastering for digital release. The main differences are:

1. narrower lowest octave
2. LPF at 15kHz
3. minimal to no compression, no limiting nor clipping
4. avoiding excessive sybillants ‘S’
5. high resolution (24/48, 24/96, etc.) file delivery for the cutting plant

Audio mastering is not magic. If your mix is inferior, the mastering process will not transform it into a first class one. It will make it sound better but probably not to the extent you may be expecting. My advice is to always work on your mix until it sounds exactly how you want it, or as close as possible. There really is no point in spending money on mastering when the mix itself doesn’t work, and I can almost guarantee that you will end up being disappointed with how the master of your mix sounds.

You can get an instant quote by choosing the service you are interested in from the Job Order/CART menu. All you need to do is to enter the number of items (songs) required in the Order Details section, choose delivery date and your price will be shown in the Order Summary section.

Yes, but why? That’s what the volume button is for!

There has been a lot of talk about the so called loudness war which has been going on for the past few decades. I think most people involved in audio engineering are aware of the loudness war, yet many of them still chase their own tail, why is that ?
This is really complicated issue, not easy to resolve, but seems it went so far, that it became a noticeable problem for all music lovers. …..tbc:)
