- when downmixing an Opus decoded stream to mono, whether this is done inside the decoder
- or as a post-processing step on the stereo decoder output. Opus intensity stereo allows

- This provides better stereo quality than forcing the two channels to be in phase,
- but when the output is downmixed to mono, the energy in the affected bands is cancelled
- sometimes resulting in audible artefacts.
+ <section title="Integer wrap-around in inverse gain computation">
+ <t>
+ It was discovered through decoder fuzzing that some bitstreams could produce
+ integer values exceeding 32-bits in LPC_inverse_pred_gain_QA(), causing
+ a wrap-around. Although the error is harmless in practice, the C standard considers
+ the behavior as undefined, so the following patch to line 87 of silk/LPC_inv_pred_gain.c
+ detects values that do not fit in a 32-bit integer and considers the corresponding filters unstable:
