Mid side encode normalization · case 05
An unnormalized mid/side matrix doubles channel amplitudes.
Case contract
Encode stereo left/right frames as normalized mid=(L+R)/2 and side=(L-R)/2 for a sum/difference channel representation.
Why this case matters
A pure Python local audio pipeline stage with explicit sample formats and frame conventions; no real-time device or signal-spectrum claims.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| fixture 1 | [[2, 0]] | [[1, 0]] | Failed |
