Zusammenfassung:	There are provided methods and apparatus for encoding/decoding audio signal information. The encoder may determine if a signal frame is useful for long term post filtering (LTPF) and/or packet lost concealment (PLC) and may encode information in accordance to the results of the determination. The decoder may apply the LTPF and/or PLC in accordance to the information obtained from the encoder.
