### Basic info - Commit SHA: main - Platform: all ### Bug description In the ParamMC a limiting is applied to the ILDs when the differences between frames would be too large. It is done only on non-transient frames. When having a small silent portion with a low energy portion following (as happens with the processing for selection testing where the items are concatenated to themselves before encoding), the transient detector does not detect a transient frame but the energy limitation is very large and leads to audible and visible artifacts. ### Ways to reproduce E.g. with `FhG_5_1_Ambience_voice_01.wav` from the 5.1 selection test material, coded with 64kbps, the repetition of the coded item shows missing energies for a number of frames in some bands at the beginning.  <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them. Add further information to the first row and remove and add labels as necessary. -->
