Separate centre from sides and treat them apart.

Any stereo track can be viewed as a mid channel, everything common to both speakers, and a side channel, everything that differs between them.

Splitting them lets you treat the centre and the edges of a mix independently, which is one of the most useful moves available in mastering.

Key points

  • Returns two files: the mid (centre) and the side (stereo difference).
  • Lets you EQ or compress the centre without touching the sides.
  • Recombines perfectly, because the split is mathematical rather than estimated.
  • 1 token per run.

What it is good for

  • Mastering moves. Brighten the sides for air without making the vocal harsh, or tighten the centre bass without narrowing the mix.
  • Diagnosis. Listening to the side channel alone tells you instantly what is genuinely stereo and what is not.
  • Mono checking. The mid channel is what a mono listener hears.
  • Targeted repair. Fix a problem that lives only in the centre or only in the sides.

What it costs

Mid/Side Splitter costs 1 token per run. Tokens work across every tool, so one balance covers everything here. A Studio subscription at $19.99 a month includes a monthly allowance and the full engine alongside it.

Common questions

Is mid/side the same as left/right?

No. Left and right are the two speakers. Mid is what they share and side is how they differ. A vocal panned centre lives almost entirely in the mid; a wide reverb lives almost entirely in the side.

Does splitting and recombining change the audio?

No. The conversion is exact arithmetic, so recombining without processing returns the original file.
