Upon successful receipt of your files, you will receive a confirmation of receipt. After reviewing your files, we will send you an invoice for your project. You can conveniently pay via PayPal or bank transfer. Once the payment is received, we will commence with the production.


Usually, you will receive your project within 2 business days after payment. During busy periods, this may take up to a maximum of 5 business days. In any case, after receiving payment, we will inform you of the estimated completion time.


Basically with effects.

If you have routed the reverb/tail through "send effects," please send us the clean reverb bus. This way, we can listen to the color and tail of the reverb and select a similar reverb.

So, please export the tracks once completely without effects and once with effects. Ensure proper labeling so that we can immediately distinguish between tracks with and without effects.

Yes, you are welcome to keep automations when exporting tracks. This means we don't have to spend time recreating them. Ideally, you should indicate in your project description where you have installed automations so that we can check them and expand or reduce them if necessary.

In general, yes - Cleaning and trimming your audio tracks of unwanted noises or signals saves us time and, consequently, saves you costs! Here are some things you can do in advance:

  • Clean your tracks of unwanted noises, breaths, etc.
  • Cut and synchronize doubles to the main track.
  • Pitch correction.
  • Synchronize the pitch of main tracks and doubles.

Of course, we can do this for you upon request.

Very easy. You export all audio tracks with the same starting point. This way we can drag your audio tracks into our project and everything will be in the right place.

No. Feel free to leave the volume distribution within your project as it is. We can increase or decrease the volume of the tracks as needed.

A detailed description of how you want your song to sound in the end is very helpful for our work. It saves us from having to guess what you might like and allows us to directly focus on implementing your wishes. The more precisely you describe what you want, the quicker we can achieve the desired result. Ideally, you would specify the exact time in the project and on which track you want specific changes.

For example:

  • At 1:31, please add a quarter-note mono delay to the lead vocal.
  • At 2:20, reduce the volume of the guitar using automation.

You can also describe individual tracks, such as how you'd like the sound of the snare or your vocals. If you have a reference song in mind, you can use it as a point of reference.

For film sound we recommend the following:

  • Export all audio tracks starting from position 0.
  • Label audio tracks sensibly: e.g. “Atmo”, “Music”, “Dialogue”, “Voiceover”.
  • In addition, please export and send the film including PGM sound (program mix) as an .mp4, .mov, .mpeg or .avi file.

In exceptional cases – if there's truly no way to obtain the original WAV file, we will accept an MP3.

Unfortunately, an MP3 is inadequatefor audio processing. Converting from an uncompressed audio format (such as Wave PCM) to an MP3 involves removing frequencies and simulating them using psychoacoustics. This means you hear something that isn't actually present. As a result, one minute of MP3 is significantly smaller in file size than a Wave.

To achieve the best possible result, you should always work with the highest resolution and only convert to the desired output format at the very end.

Yes. However, please note that the workload, and therefore the price is higherin this case. We need to navigate within your project structure and manually adapt your project to our workflow. Additionally, it's possible that we may not have certain plugins you've used in your project..

We do accept project files from the following DAWs:

  • Logic
  • Protools
  • Cubase

It's important to render your audio tracks, including the plugins that must remain on the tracks, before sending them. We primarily work with analog equipment, so there's a chance that we may not have all the plugins used in your projects.

For digital delivery, such as streaming services, we recommend 24-bit and 48 kHz.. However, there are also aggregators (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 (charges apply). For CD the standard is 16 bit and 44,1 khz. For vinyl we recommend 24 bit and 48 khz – 96 khz. A subsequent playout in a different file format is possible at any time. We charge 10 euros per playout for this.
The volume of a vocal recording As a rule, it should be such that it can be easily understood without you having to shout or whisper loudly. It's important that the recordings are loud enough to be comfortable to listen to, but not so loud that they become 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 peak limit for a vocal recording should be between -XNUMX and -XNUMX dB to avoid distortion. However, it's important to note that these recommendations are guidelines, and the optimal volume and peak limit should be determined individually for each recording.


All files must have the same starting point. Please send all tracks once WITH and once WITHOUT effects (reverb, EQ, compressor, etc.).
As high as possible. 32-bit floating point (if possible) or 24-bit for other sequencers like Logic or Pro Tools. For MP3, use 16-bit (please avoid delivering in MP3).

Panorama settings can generally be retained. If we need them to be different, we will contact you.
Volume levels can be retained.
A headroom of 2-3 dBFS is sufficient.
"Trim allowance" should be left. Please leave at least 500 ms of lead-in time. This is especially important for tracks mixed on analog technology consoles (for Predict/Fingerprints denoising).
No limiting (except as a "creative effect")
No limiting in the summing stage.
Light peak limiting is acceptable, but please avoid using Finalizer or similar tools. The loudness should not exceed approximately -15 dB RMS.
Please send tracks both with and without effects. Feel free to include descriptions of the desired effects along with reference examples, if possible.
Please provide appropriate labels for the tracks (e.g., Main Voice, Beat, etc.).
Precede the songs with the correct track number, for example: "01-my song.wav."
Feel free to provide them if you have a specific sound in mind.
You can also include 2-3 reference tracks.
Please include a tracklist with suggestions or requests. If possible, provide tempo information and a preview version of the mix you desire.
Include information for CD-Text (Artist/Song Name/Text/Music), and ISRC if desired.


The test mastering costs 10€. At the Test Master we make a regular one online masteringprocess. However, instead of the full song, you receive a 90-120 second excerpt. This involves significant work and costs for electricity, etc., so we can't offer it entirely for free.
The difference between analog and digital audio processing and what sounds better or different between them is explained in a separate article we have provided. For more information you can access the article on analog vs. digital.

Of course. Simply give us brief feedback here and we will send you a link to upload without you having to enter all your data again.

For an additional fee of 60€, we can create a DDP (Digital Disc Protocol) according to the Sony Redbook standard for your pressing plant.
If you have described your project in detail and everything is clear to us, we will start production immediately after receipt of payment. If you wish, you can of course arrange an appointment with us in advance to discuss the project. Book an appointment directly in our calendar.

We typically need between 3 and 5 business days to complete a single song. Depending on the order situation, times may vary.

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

After delivery of your online mixing or our 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 additional charge. Basically, 2 change versions are included in the mastering. The exception here is the exchange of the file by the customer. This involves considerable additional effort compared to changing the title that has already been edited.

Yes, of course! Please feel free to contact us. Together we will arrange either a studio appointment or an appointment for a remote session. You can find more information about our remote mixing and remote mastering at the following link:
