48 kbit/s Stereo, DTX on: Decoder introduces clicks

Basic info

  • Fixed point:
    • Encoder (fixed): n/a
    • Decoder (fixed): 97c3fd94

Bug description

When decoding the bitstream with the BASOP decoder, the decoder introduces serveral audible clicks. Some of them seem to be for the transition active -> inactive, some other seem to come from PLC.

BASOP Decoder: Bildschirmfoto_2025-09-10_um_22.32.55

The clicks are not there with the float decoder.
