Spike caused by BASOP encoder in OMASA LTV input

Basic info

• Float reference:
  • Encoder (float): db364042
  • Decoder (float): db364042
• Fixed point:
  • Encoder (fixed): f1458362
  • Decoder (fixed): f1458362

Bug description

There seems to be a clipping or similar saturation spike in OMASA caused by BASOP encoder. See the figure below. This is with BASOP encoder to float decoder but same spike is there for full BASOP path.
