BER detect in Stereo Decoder at 13.2 kbps DTX

Basic info

  • Encoder (float): ceb8871f
  • Decoder (float): ceb8871f
• Fixed point:

Bug description

Enabling debugging in float reference decoder results in BER detected error for bitstream encoded with BASOP encoder. The issue is present for multiple stereo items only in this specific combination:

BASOP encoder + Floating Point decoder debugging enabled.

Error message is:

Frames processed: 8454 Decoding error: BER detected in frame 8453 !!!!!

Floating point encoder (whether or not debugging is enabled) + floating point decoder (whether or not debugging is enabled) do not result in BER detection.
