### Basic info - Commit SHA: 6c9ddc402 - Platform: windows ### Bug description This has been identified while working on https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/issues/1406. Basically, in rare occasion bwe_non_lin_prev_scale gets very high during inactive/unvoiced frame having low energy **and if** the next generic/tc frame has a sharp increase of energy at **the beginning** of the frame, then the bwe_exc_extended get scaled with a very large energy. The SWB_TBE has no mechanism to scale down the frame energy (minimum tbe "frame gain" is 1.0), thus this energy overshoot is not corrected. Figure below shows the 2 channels of the original signal and the floating point synthesis at that place. {width=1228 height=722} ### Ways to reproduce Check synthesis of this bitstream at approx. 43 seconds [bit_new.dtx](/uploads/1100edbba8762d4a548ce0628007f340/bit_new.dtx) IVAS_dec STEREO 32 bit syn <!--- Below are labels that will be added but are not shown in description.
