Answers to almost all questions
that I was asked about binaural audio.
What is binaural audio and what do I need it for?
The binaural recording technique records the sound that falls into the ears in the same way as it is perceived by the human hearing organ. The sound signals obtained in this way are reproduced using headphones. In this way, external influences on the sound are eliminated. The recording can use an dummy head or even a torso with different details or use the sound engineer’s own head. The sound engineer can move during the recording. The dummy head microphone, on the other hand, is usually kept stationary.
In this way a remarkable realism can be achieved. This, however, is limited by the restriction of head movement and the enclosing effect of headphones. The happy listener therefore gets a good match and impressive realism.
What is the difference between binaural audio and stereo?
In general, stereo sound recordings are mixed exclusively using loudspeaker systems during listening; hence the name „loudspeaker stereo“. The properties used by humans for localization, such as the shape of the head or ear, are rightly not taken into account, because in natural hearing and in reproduction via stereo speakers, the ear forms the aural signals itself.
On a regular stereo system with speakers (not headphones), the listener’s left ear will hear both speakers and the right ear will hear both speakers too. If the left ear hears only the left speaker and the right ear hears only the right speaker, there is no crosstalk. In other words, crosstalk occurs when the left ear also hears the right speaker and the right ear also hears the left speaker. So when a listener hears a stereo signal through headphones, there is no crosstalk and the left and right channels are completely separated. Thus, the intended listening experience of a sound engineer mixing with speakers will differ significantly due to the lack of crosstalk when listening through headphones. The sound sources are lateralised and there is typically a loss of energy in the centre of the sound image compared to the loudspeaker reproduction of the same recording. The localization is therefore considerably limited. The sound sources reproduced in this way are localized in the middle of the head.
The term „binaural“ is unfortunately still confused with stereo because it also consists of two audio channels.
However, in contrast to stereo playback via headphones, binaural signals contain the crosstalk of sound signals described above. These are embedded spatial indications in the form of time, intensity and spectral coloration. These signals imitate and improve natural human localization. The target reproduction system for binaural signals is primarily headphones. When properly recorded, synthesized and reproduced, binaural signals produce a convincing impression of spatial sounds as they occur in the natural listening environment.
How do I prepare my stereo mixes for binaural mixing?
The short answer is: please create 32-bit floating point files of the instrument tracks with the same sampling rate as your mixing session in WAV or AIFF format. If possible, don’t limit or change the volume of the mixes too much. There should be enough headroom for a high-quality and natural sounding binaural mix. If you have several microphone signals from one instrument, please mix them down to a single track. Do not include any spatial information in the track, unless the artist (e.g. a guitarist with his effect pedals) wants this.
Avoid digital overloads and distortions in any case.

Is there a supplement for revisions?
Yes and no. As long as I work with the same instrument tracks, I offer unlimited revisions at no additional cost until you are completely satisfied. Fortunately, it is rare to go beyond version 2 or 3. And in general, these revisions have more to do with adjusting the timing between tracks than with the sound itself. However, you have the right to request changes to any aspect of the binaural master at no additional cost.
However, if you decide to edit your tracks again and have to send a new version, this will incur additional costs. Contrary to popular belief, I can’t just open the new mix file and use the same settings. We need to consider the time needed for file management, conversion, rendering and reloading. Even if no analog device is used, loading a new file, rendering a new master, and sending a new master for approval takes longer than you think. If you hear small mixing or editing errors in your mix after the binauralization is complete, I offer you a discount for revisions of new mixes at a price of 13 Euros per song. However, only if there are small changes to the mix.
What can I do?
It is VERY important that you check the files twice and three times before sending them for binaural mixing. I see too many people having to go back one step to correct simple errors. Errors caused by their DAW or a plugin that could easily have been avoided. Just listen critically to the individual tracks before sending them for binauralization.
In the very unlikely case that the binauralized songs don’t sound extraordinary after coming out of my studio, I will do free reviews. Until you are satisfied with my work. Should you be dissatisfied for any reason, please let me know. I will do everything I can to make things right. My goal is to keep you as my customer, and I am proud to have excellent customer service in the studio industry. I want to make sure your binaural audio experience is as enjoyable as possible.
How do payment and delivery work?
To book a project, all you have to do is pay the quote via Paypal or make a bank transfer to my account. Once the payment has been registered, you will receive a detailed e-mail with the current status and how to proceed. When your project is finished, I will send you a link to the mastered WAV files or the DDPi file. If you have any special requests, just let me know.
Does the *.zip – format affect the audioquality?
„Zipping“ your audio files has no effect on their audio quality! It only makes downloading large files for online music mastering much easier. However, I would recommend using only and exactly this format, namely . zip“ and NOT „.rar“.
Before uploading your files, please create only this one zip file containing all your files. Include an image (jpg) of your cover, if available. You can also upload each file separately, but using a single ZIP file containing all your songs will provide additional protection for your files.
Please name the zip files with the artist name and version number (Artist_Name_V1). If you send missing files or replacement files for an already running project, please enter a new version number in the zip file name (Artist_Name_V2 or Artist_Name_V3).
Please add all relevant information into the news section of the WeTransfer Uploader. Even better is an email or even a text file contained in the zip archive.
Do you also do binaural mixing for individual songs?
Yes, of course I do. Mixing a single song is a quick and easy way to get your professional binaural audio online. This is an excellent, cost-effective solution for artists who only need one or two songs.
You can find a contact form by clicking on this link. Fill it out and return it to my e-mail address. Then please send me a link to download your song (via WeTransfer or Dropbox). The rest will run automatically.
