Please do not use dithering.
Please do not use dithering.
Please do not use fades.
Please do not use fades. The only exception: arranged fades in which different parts of a song have to be faded separately. If you want fades, please indicate this
Panorama settings can basically be retained - if we need them differently, we will contact you.
Volume ratios can be maintained.
2-3 dbfs Headrom are enough.
Leave “bleed allowance”. Please allow at least 500 ms advance. This is especially true for titles that are mixed on consoles with analog technology. (Predict / Fingerprints for Denoising).
No limiting (except as a "creative effect")
No limiting in the sum range
Light peak limiting: yes, finalizer or otherwise please don't! The loudness should not exceed approx. -15 db / RMS.
Please send tracks once with and once without effects - a description of the desired effects with reference examples is also welcome, if possible.
Please give the tracks the appropriate name (e.g. main voice, beat, etc.)
Please give the pieces the correct track number in advance: "01-mein song.wav"
Gladly, if you want a specific sound.
You are welcome to enclose 2-3 reference titles.
Please enclose a list of titles with suggestions or requests. If possible, include the tempo and preview version of the mix you want.
Please enclose a list of titles with suggestions or requests. Information for CD-Text (artist / song name / text / music), ISRC if desired.


Basically yes.

If you routed the reverb/reverb via "Send-Efx", please send us the pure reverb bus. This way we can listen to the timbre and reverb tail carefully and pick out a similar reverb.

So please export the tracks once completely without effects and once with effects. Please also pay attention to the labeling so that we can immediately see which track has effects and which without.

No - you can export your tracks as you created them in the project from the level - if we need a track louder or something is exported much too quietly or too loudly, we would contact you again and request the track .

Basically yes - cleaning and trimming your audio tracks from unwanted noises or signals saves us working time and thus costs you! You are welcome to do the following things in advance:

  • Clean your tracks of unwanted noise, breathing etc.
  • Cut doubles synchronously to the main track
  • Correction of intonation
  • Synchronize intonation of main tracks and doubles

Of course, we can also do this for you if you wish.

A detailed description of how your song should sound in the end is very helpful for our work. We don't have to think about what you might like first, but can take care of the implementation of your wishes directly. The more precisely you describe what you want, the faster we can reach our goal. Ideally, you write the exact time in the project and on which track you want to have what exactly.


  • At 1:31 on the lead vocal please add a quarter mono delay.
  • At 2:20 please turn down the guitar via automation.

You can also describe individual tracks. For example how you would like the sound of the snare or your vocals to be. If you can think of a reference song, you are welcome to name it as a guide.

In exceptional cases - i.e. if there is really no possibility of getting the original wave - we also take an Mp3.

An mp3 is for audio editing unfortunately insufficient. By converting an uncompressed audio format (such as Wave PCM) to an mp3, frequencies are left out and simulated using psychoacoustics. That is, here you hear something, what actually not available is. Therefore, one minute of mp3 in terms of data size is significantly smaller than one wave.

In order to be able to achieve the best possible result, one always works with the highest resolution and only converts to the desired output format at the very end.

Yes. Here is the workload – and therefore also the price higher, because we first have to find our way around within your project structure and only have to redesign your project manually according to our way of working. In addition, it may be that Plugins that you used in your project we don't have.

Of course, we also take project files from the following DAWs:

  • Logic
  • protools
  • Cubase

Important to note: Before sending, render your audio tracks including the plugins, which should definitely remain on the tracks. For the most part, we work analog, so it can happen that we don't have one or the other plug-in that is used in your projects.

We have provided you with the difference between analog and digital audio processing and which of them sounds better or different in an extra article. Here is the article Analog vs Digital.

For digital delivery e.g. B. for streaming services we recommend 24 bit and 48 khz. However, there are also agregators (e.g. Recordjet) which only allow a sample rate of 44,1 kHz. Please check IN ADVANCE which format you need or have several formats played out at the same time (subject to a fee).

For CD, the standard is 16 bit and 44,1 kHz. For vinyl we recommend 24 bit and 48 kHz – 96 kHz.

Subsequent playout in a different file format is possible at any time. For this we charge 10 euros per draw.

The volume of a vocal recording should generally be such that it is easy to understand without you having to yell or whisper loudly. It's important that the recordings are loud enough to be comfortable to listen to, but not so loud as to be uncomfortable or cause distortion.

The peak limit refers to the maximum volume that can be reached in a recording before distortion occurs. This limit will be in Decibels (dB) measured and depends on the quality of the recording and playback devices. Usually the Limit of the peaks in a vocal recording between -6 and -3 dB lay to avoid distortion. However, it is important to note that these recommendations are only intended as a guide and the optimal volume and peak limit should be determined for each recording individually.


Upload your file now - we will usually get back to you within 3 hours (on working days).


The test mastering costs 10€. We will credit this back to you when you buy the full version.

With the Test Master we produce a regular online mastering. However, instead of the full song, you will receive a 90-120 second excerpt. This is associated with a considerable amount of work, as well as costs for electricity, etc. Therefore we cannot offer this completely free of charge.

With the credit when purchasing the full version, we have a fair solution for everyone.

Usually not. That Test master serves to give the customer an impression of the end result which is possible through the processing of Peak Studios. For larger orders such as B. in the case of an album production, things look different. Here you can, if necessary, prepare a second test master after discussing the details.

For a surcharge of €60, we can make one for you in the press shop DDP (Digital Disc Protocol) according to the Sony Redbook Standard.

Usually we need between 3 and 5 working days to complete a single song. The times may vary depending on the order situation.

Your files are in good hands with us. We archive all production-relevant traces and notes for you. For a surcharge, you ALWAYS have the option to access your files, settings and notes at a later point in time.

After delivery of your Online mixing or ours Online mastering, you have 7 days to express your change requests. No fear. If you need more time, you can extend the feedback time for a small fee.

Basically, 2 change versions are included in the mastering. Except here is the exchange of the file by the customer. This involves a considerable amount of additional work compared to changing the title that has already been edited.

Naturally. We have a cloud secured with SSL encryption for uploading and downloading. This is how we guarantee maximum security. In addition, your data is ISO 27001 certified and protected.

With us, you as a customer have the option to choose between PayPal, bank, prepayment, cash or transfer. When paying with PayPal, we charge the fees for payment processing separately.

Payment in installments is generally possible from an order value of over 200 euros.

Usually no, because of the effort for one Test mix is much higher than for a Trail mastering. If it is a question of a larger production (e.g. album, etc.), we will of course make an exception from time to time.

The following applies to our customers: right of withdrawal disappears when you click the "send button and choose a paid service"


For production jobs that require the processing of audio material, there is only one restricted right of withdrawalbecause this is "Build to order"Services. The legislature decided that "Made to measure" orders - what in our case Mastering, mixing as well as any changes to audio material according to customer requirements, are excluded from the right of withdrawal Section 355 (2) of the German Civil Code (BGB), new version.
