What is audio mastering? audio mastering or just mastering called, is the last step in the post-production or audio processing or refining of audio material after mixing your tracks. The aim of mastering audio material is to create a balanced frequency response in all frequencies so that the song or track can be played on many playback sources sounds as good as possible. Individual frequencies, dynamics, loudness and energy distribution in the track or song must be taken into account here. An appreciation of the existing sound material is often, after Mixing, he wishes. In many cases, it is not only the task of the Mastering Engineers to make the song as compatible as possible with the various playback devices in the recording studio, but also Mistakes in the mix to reduce as much as possible and a good one stereo image to accomplish.

The Music production is it common practice that mix or that Mixing and the mastering are separated and each one different Recording studio is used, which specializes in the challenges of the individual sub-areas within music production. So find yourself more and more providers for the so-called Online mixing or Online mastering. The song is edited online by a mixing engineer and sent digitally to the artist for approval.


Both Center and side signal, left or right channel, can and will in Audio mastering often edited separately. The possibility of influencing the signal or sound of the music is therefore greater, which in turn leads to better and cleaner results that can be used when mixing erroneous use, e.g Compressor were caused. Interfering signals, unwanted noise, crackling and crackling, deessing, as well as dynamics and levels are optimized in different sequences in the editing process and unwanted ones are largely reduced. When audio mastering is always to consider between the reduction of interference frequencies and the preservation of the basic sound and dynamics within a song, sound, entire music or track. Therefore, handling the compressor or equalizer is particularly important and requires the greatest precision when mastering a track, because ultimately it should sound good in the end!


For the processing of the material to be mastered, a DAW is first required to play the song. There is software specially developed for audio mastering, such as “Wavelab” from Steinberg. However, it is also possible to carry out an audio master in any DAW (e.g. Cubase, Logic or ProTools) and get missing functions using third-party plugins. But not only the right DAW is needed for editing. External hardware processors designed for mastering, e.g EQ or Compressor, ensure a well-rounded track sound and ideal processing of the raw material after mixing. A good selection of high-quality plugins are also used in the music master.

More factors like that studio acoustics, the right monitoring monitors, cabling or the choice of the right one mastering devices, are just as important in audio mastering as a good ear and the necessary genre experience of the material to be processed. So knowledge is also power when it comes to mastering frequencies.

How well the track or music can be edited in the master depends not only on the recording (Recording) but also on the quality of the sound in the mix. These are all part of the music production.

Thanks to digitization, more and more audio mastering studios are now offering their services online. The so-called "e-mastering"Or"Online mastering".

But does this really make sense? How was mastered in the past?

Before digitization, artists and bands searched for you with great difficulty Mastering studio where you personally participated in the mastering session.

Any changes to individual parts of the audio material or the songs of the musicians and artists could be directly examined, heard and the track judged good or bad.

A targeted implementation of the sound ideas of the individual songs was therefore no problem. Should changes in the mixing be necessary, everything could be initiated directly with the musicians, so that all the individual elements in the music production could run smoothly together.

Nowadays, this is solved using so-called "versions". After completing the online audio mastering, the artist gets his audio material back for assessment and has the opportunity to have corrections made to the master version by the mastering engineer by means of change requests.
