What is audio mastering?

Audio mastering, often simply called "mastering," is the final step in music production. After mixing, mastering ensures that your song's sound is refined, adjusted for loudness and tonality, and prepared for all playback systems. The result: a track that sounds professional and balanced everywhere—whether on headphones, streaming platforms, on the radio, or in a club.

Mastering explained:
Mastering is the technical and sonic refinement of a song after mixing. Levels, dynamics, and frequencies are adjusted so that your song sounds optimal across all channels.

 

What happens during mastering?

During audio mastering, your finished mixdown is specifically edited:

  • Stereo image optimization: For a wide, three-dimensional soundstage.

  • Frequency correction: Balanced from sub-bass to air band to reduce disturbing frequencies.

  • Loudness optimization: Adaptation to loudness standards (LUFS) of the target platforms.

  • Limiting & Compression: Control of dynamics for maximum assertiveness without Clipping.

  • Metadata: Song titles, artists and other information will be added for release.

Even Mid/Side processing, Removing interference signals (e.g. noise, crackling), de-essing and targeted dynamic processing are part of everyday mastering.

Process of a professional mastering

1. Import & Analysis:
Your song will be delivered as a mixdown (ideally WAV, min. 24 Bit, at least –6 dBFS headroom). Level, frequency distribution, stereo width and dynamics are analyzed using measuring tools and hearing.

2. Frequency processing:
Equalizers are used to compensate for small inconsistencies in the frequency spectrum.

3. Dynamic processing:
Compressors and limiters ensure controlled loudness and maximum presence.

4. Loudness adjustment:
Your song will be optimized to the target loudness (LUFS) and the respective true peak values ​​of the platforms, taking into account the following normalization values:

PlatformTarget LUFSTrue Peak (max)
Spotify–14 LUFS–1.0 dBTP
Apple Music–16 LUFS–1.0 dBTP
YouTube–14 LUFS–1.0 dBTP

5. Export & Control:
After the final limiting you will receive your master as WAV, MP3, DDP image or Vinyl Master – ready for publication.

IMPORTANT: This does not mean that the song should be mastered to this value, but simply that streaming services normalize the song to this value in order to ensure a uniform playback loudness of all tracks!
