Code

For IETF draft

  • Multi-channel signalling (done, needs more testing)
  • Make opus-compare fail for single seriously trashed frames?

SILK issues

  • CLANG ARITHMETIC UNDEFINED at <silk/decode_core.c, (108:40)> : Op: *, Reason : Signed Multiplication Overflow, BINARY OPERATION: left (int32): 916258817 right (int32): -3
  • CLANG ARITHMETIC UNDEFINED at <silk/decode_core.c, (108:40)> : Op: +, Reason : Signed Addition Overflow, BINARY OPERATION: left (int32): -418535217 right (int32): -1832517634
