Stereo analysis of a mix
- Input
- mixdown_stereo.wav
- Expected output
- mixdown_side.wav (apenas conteúdo diferencial)
If the Side channel is very low in volume, the mix is essentially mono. If very loud, there is aggressive stereo content.

Mid-Side (MS) encoding decomposes a stereo signal into two orthogonal components: Mid (M = (L+R)/2), which contains what is common to both channels, and Side (S = (L-R)/2), which contains only the content unique to each channel. This decomposition is widely used in mastering to control stereo width independently from the center.

Open full toolWhat are the Mid and Side channels?
- Mid-Side (MS) is a stereo representation technique that decomposes the signal into two components: Mid (M = (L+R)/2) contains everything centralized — vocals, kick, bass. Side (S = (L-R)/2) contains only the differential content — reverb, width, panning effects. Separating these channels allows independent processing of the center and width of a mix.

Full tool FAQ
Average mixdown sums L and R and divides by 2, which preserves centered content (vocals, kick) but can cause phase cancellation in content recorded in opposite phase. The L and R modes simply discard one channel — useful when only one channel has valid content or to guarantee no cancellation occurs.
Frequently asked questions
The Side channel can be very quiet — is that normal?
Yes. Songs with little stereo content (voiceovers, centered studio recordings) will have a very quiet Side channel. Songs with heavy reverb, wide-stereo synthesizers, or panning effects will have a louder Side channel.
Does this page replace official or professional review?
No. It helps explain the scenario and use the tool more safely, but real decisions should consider official sources, full context and qualified guidance when needed.
