M/S Peak Bound
Estimate the worst-case decoded sample peak after adjusting Side gain.
Mid sample peak (dBFS): -160–0; Side sample peak (dBFS): -160–0; Side gain (dB): -60–24

For L = M + S and R = M − S, the peak bound is 20 log10(10^(M/20) + 10^((S+G)/20)), where M and S are sample peaks in dBFS and G is Side gain in dB. Attenuation is the positive excess above 0 dBFS. The two peaks may occur at different times, so this is a conservative bound, not a measured peak. Verify decoder scaling and measure true peak separately.
Methodology
How it works
For L = M + S and R = M − S, the peak bound is 20 log10(10^(M/20) + 10^((S+G)/20)), where M and S are sample peaks in dBFS and G is Side gain in dB. Attenuation is the positive excess above 0 dBFS. The two peaks may occur at different times, so this is a conservative bound, not a measured peak. Verify decoder scaling and measure true peak separately.

Frequently asked questions
Does this predict clipping?
No. It bounds sample peaks for the specified matrix. Decoder normalization, downstream processing and intersample peaks are outside this model.
