3D Audio Post Mixing

For your multimedia, audiobook or music project, I offer post mixing and mastering of mono, stereo or binaural tracks or stems including editing and positioning of music, dialogue, SFX, foley and atmos sounds anywhere within a full 360° three-dimensional sphere.

Binaural 3D Audio simulates the human spatial hearing via every kind of stereo headphones (no special models are required). When listening to stereo audio with headphones, the perception of all sources of sounds is located inside of the head between the left and right ear. With binaural 3D Audio the sound appears outside of the head and can be anywhere within a full 360° three-dimensional sphere. Voices, instruments and sounds can be positioned around the listener - in front of, behind, right, left and even below or above and everywhere in between.

Binaural 3D audio sounds amazing in audiobook, radio play, shortfilm or documentary video productions and can enrich the listening experience of dialogues, atmos, foley, sound effects and music. But also music productions of artists and bands that are mixed as binaural 3D audio can sound interesting as an alternative to stereo mixing. There are also more immersive multichannel audio formats such as Ambisonics that are used for audiovisual presentations, sound installations and AR/VR projects.

My 3D audio editing services includes panning, positioning and automated movements as well as level and fades adjustments, cuts, restoration and noise reduction, equalizer sound editing, virtual rooms and environments, delay, spectral shaping, dynamic compression, vintage sound coloring, saturation and limiting of mono, stereo, multichannel or binaural 3D audio tracks, stems und mixes. Delivery of various digital audio formats (WAV, AIFF, MP3, AAC, FLAC, OGG) and DDP premaster for CD duplication.

Sound Design

For your audiobook, shortfilm or documentary video production, game, audiovisual presentation or AR/VR project, I can create individual mono, stereo and immersive audio music and sound elements.

Sound Design can include individual music composing and production of different genre such as Fusion World with a focus on Oriental music, Jazzy Soul Vibes and Electronic Soundscapes as background music or soundtrack for audiobooks, documentaries, film and theatre plays. Also I can create single sound effects for games, apps and virtual reality productions. Additionally I offer licensing of existing tracks and individual variations as well as binaural atmos and foley recordings, virtual ambience audio scenes and sounds from my archive.
