Mono compatibility in music production

Under Mono compatibility understand them as possible lossless playback option on playback devices with only a loudspeaker. Strictly speaking, with a mono signal, the original stereo signal from the left and right channels is mixed together. One speaks here of a "mono reproduction".

Why is mono compatibility so important?

The mono compatibility in music production is so important because with a good ratio between the middle and side signal, the song is perceived in its balance in a much more balanced and powerful way. Especially with playback media with only one loudspeaker, or with many club PAs, playback is in mono.

In addition, many club sound systems, smartphones, tablets or other playback and playback media still only reproduce their sound in mono. So here it is very much a question of how much of the original sound is played on such devices.

How can one find out the mono compatibility?

The mono compatibility can be achieved with a so-called Correlation meter or goniometer determine. Often the conventional audio interfaces also have a mono switch with which the middle signal can be output in isolation. It is therefore advisable for the mix and also for mastering Check the mono or mid-range signal and possibly less to mix in stereo. With panning up to approx. 65% (of 100) you usually get few problems with the Mono signal.

Which instruments / sounds should be mono compatible?

In order to answer these questions, we first have to ask ourselves which elements in our production are so-called "lead sounds".

Example of lead sounds within a song:

  • Kick drum
  • bassline
  • Snare
  • Hi hats
  • Lead synth
  • Piano

Of course, this list could be continued. It is only intended to show that all components that are important should have a certain degree of monocompatibility. This can be a problem with a “lead synth”.

Our tip for a good mono compatibility of stereo sounds:

  1. Simply duplicate the stereo sound as a track.
  2. A stereo imager is placed on the duplicated track.
  3. Now set the entire signal to mono.
  4. Mix in the pure mono signal at will, depending on the volume.



We make sure that your song has the correct stereo width and sufficient mono compatibility.
