FA-11022 / Audio channel mixing / Member archive
Mid side decode reconstruction · case 02
Decoder halves amplitudes even though normalization was already applied during encoding.
Case contract
Decode normalized mid/side frames into left=mid+side and right=mid-side, exactly inverting the half-scaled encoder.
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 | [[0.5, 0.5]] | [[1, 1]] | Failed |
