How to convert with downmix 5.1 to stereo

 

 

Sound quality issues

 

Channel number reduction is not a purely technical procedure. How to downmix 5.1 to stereo is an element of art.

Played multichannel record back may have a different sound depending on the listening room and apparatus with its settings.

When studio producers have original mono tracks for each sound source of the record, their spatial locations can be modeled mathematically. The calculation may be done for a given channel number N. In instance, N=6 or 5.1 or five speakers and subwoofer. As result, we get several N-channel tracks. They are united into a single N-channel bus. And, N-channel recording is distributed.

5.1-to-stereo converter or downmix plugin of digital audio workstation has this distributed record as input. So there are issues with the sound source separation. And channel number conversion is not the same as the above-mentioned studio work, where sources may be separated.

Studio records may be provided in several variants with the different channel number. As example, multichannel and 2.0 options of the same album.

It is not possible to say what is better in the general case: stereo variant of studio record or multichannel file, that is downmixed in conversion software. There are many conditions: original stuff, quality of math modeling, converter's algorithm, others. In the author's opinion, the best thing to do is compare target stereo records aurally.

 

 

Audio channel converter settings

 

Above we considered that no single "right" way to convert 5.1 audio to 2 channel file.

Therefore AuI ConverteR provides 2 alternative downmixing modes:

  • Mode 0 : artificial easy spatial expansion is applied.
  • Mode 1 : minimalistic processing is applied (developers consider it more "natural").
