FAQ: QUESTIONS ABOUT DATA DELIVERY & THE PROCESS

In general, please send them with effects.

If you have routed reverb via “send FX”, please also include the dedicated reverb bus. This allows us to assess the tonal character and reverb tail and choose a matching reverb if needed.

Please export your tracks once without any effects and once with effects. Make sure all files are clearly labelled so we can easily distinguish between the two versions.

Yes, you can keep all automations when exporting your tracks. This saves time, as we do not have to recreate them from scratch.

Ideally, please note in your project description where automations are applied so we can review them and adjust, enhance or reduce them if needed.

In general, yes — editing and cleaning your audio tracks from unwanted noises or artefacts saves us time and, ultimately, reduces your costs. Here are a few things you can do in advance:

  • Remove unwanted noises, breaths or clicks.
  • Cut and align doubles with the main track.
  • Apply basic pitch correction.
  • Ensure the pitch of doubles matches the main vocal.

Of course, we can take care of all of this for you upon request.

A detailed description of how you want your song to sound is extremely helpful. It prevents guesswork on our end and allows us to focus directly on implementing your creative vision. The more precisely you describe your preferences, the faster we can achieve the result you’re aiming for. Ideally, let us know the exact time position 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 guitar volume using automation.

You can also describe individual elements, such as how you want the snare or vocals to sound. If you have a reference track in mind, feel free to include it as a guide.

No. Please leave the volume balance of your project exactly as it is. We will adjust the levels during mixing or mastering as needed.

No. We would first need to familiarise ourselves with your entire project structure and then rebuild it manually according to our workflow. In addition, it is very likely that we do not have the plugins you used in your session, which would lead to missing settings or altered sound.

It’s very simple: you export all audio tracks with the same starting point. This allows us to import them into our session and have everything line up correctly in the timeline.

For film audio, we recommend the following:

  • Export all audio tracks starting at position 0.
  • Label your audio tracks clearly (e.g., “Ambience”, “Music”, “Dialogue”, “Voiceover”).
  • Please also export and send the video file including the PGM mix (program mix) as an .mp4, .mov, .mpeg or .avi file.

In exceptional cases—if there is truly no way to obtain the original WAV file—we can accept an MP3.

However, an MP3 is not suitable for professional audio processing. Converting from an uncompressed format (such as WAV PCM) to MP3 removes audio information and replaces it with psychoacoustic approximations. In other words, you hear content that is no longer actually present, which is why an MP3 is significantly smaller in file size than a WAV file.

To achieve the best possible result, always work with the highest available resolution and convert to the target format only at the very end.

For digital distribution, such as streaming services, we recommend 24-bit / 48 kHz. However, some aggregators (e.g., Recordjet) only accept a sample rate of 44.1 kHz. Please check in advance which format you need, or request multiple export formats from us (for an additional fee).

The standard for audio CDs is 16-bit / 44.1 kHz. For vinyl production, we recommend 24-bit and 48–96 kHz.

Additional file formats can be provided at any time. We charge €10 per additional export.

There are several ways to export stems including all effects, e.g. for stem mastering. In our blog post Export Logic tracks with effects, you will find all the necessary information.

The volume of a vocal recording should be high enough to be clearly intelligible without shouting or whispering. The goal is to record at a comfortable listening level—loud enough to capture detail, but not so loud that it becomes unpleasant or introduces distortion.

The peak limit refers to the maximum level a recording can reach before distortion occurs. This limit is measured in decibels (dB) and depends on the quality of the recording and playback devices. Typically, the peak level for a vocal recording should be between -6 dB and -10 dB to avoid distortion and maintain clean headroom.

Please note that these values are general guidelines. The optimal recording level may vary depending on the microphone, preamp and recording environment.

The test mastering costs €10.

For a test master, we perform the same work as in a full online mastering session. The only difference is that you receive a 90–120 second excerpt instead of the complete track. This process still requires professional processing, studio time, and energy consumption, which is why we cannot offer it entirely free of charge.

The difference between analog and digital audio processing—what sets them apart and how they affect the sound—is explained in detail in our dedicated article. For more information, please see our guide on analog vs. digital.

Of course. Simply send us a quick message and we will provide you with a dedicated upload link so you don’t have to enter all your information again.

For an additional fee of €60, we can create a DDP (Digital Disc Protocol) master for your pressing plant according to the Sony Red Book standard.

If your project description is clear and complete, we will begin production immediately after receiving your payment. If you prefer, you can also schedule a call with us beforehand to discuss your project in detail. Book an appointment directly in our calendar.

We typically need between 3 and 7 business days to complete a single song. The exact turnaround time may vary depending on our current workload. An express option is also available for an additional fee, which can be selected directly in the upload form.

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

After the delivery of your online mixing or online mastering, you have 7 days to submit your revision requests. If you need more time, you can easily extend the feedback period for a small additional fee.

Two revisions are generally included in our mastering package. An exception applies if you replace a previously delivered file, as this requires significantly more work than making adjustments to an already processed track.

Yes, absolutely! Just get in touch with us and we will arrange either a studio appointment or a remote session. You can find more information about our remote mixing and remote mastering services at the following link:

Remote mixing and mastering

Absolutely. Our upload and download environment is protected with SSL encryption, ensuring a secure transfer of your files. In addition, your data is safeguarded under ISO 27001 certification, providing maximum security and compliance.

You can choose between PayPal, bank transfer, prepayment, cash payment, or wire transfer. If you choose to pay via PayPal, the processing fees will be calculated separately.

Yes. Installment payments are generally possible for orders with a total value exceeding €200.

Generally, no. The effort required for a test mix is significantly higher than for a test mastering. However, for larger productions (e.g., a full album), we may make an exception.

For our customers, the right of withdrawal expires when you click the “Send” button and select a paid service.

REASON FOR THE LIMITED RIGHT OF WITHDRAWAL

For production orders that involve processing audio material, there is only a limited right of withdrawal because they are “build-to-order” services. The law states that custom orders — which in our case includes mastering, mixing and any modifications to audio material according to customer specifications — are exempt from the right of withdrawal in accordance with § 355 (2) of the German Civil Code (BGB), new version.
