Abstract
An apparatus comprising at least one processor and at least one memory including computer program code the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: determining from an audio signal at least a first part and a second part; encoding the first part of the audio signal with a first encoder for generating a first encoded audio signal; encoding the second part of the audio signal with a second encoder configured to generate a second encoded audio signal comprising for a first section of the second part an indicator to at least part of the first part of the audio signal; and determining the first section of the second part of the audio signal such that the first encoded audio signal and second encoded audio signal is within a defined encoding efficiency parameter.

41. A method comprising:
-
determining from an audio signal at least a first part and a second part by filtering the audio signal into a first part representing a lower frequency region and a second part representing a higher frequency region; encoding the first part of the audio signal with a first encoder for generating a first encoded audio signal; encoding the second part of the audio signal with a second encoder configured to generate a second encoded audio signal comprising for a first section of the second part an indicator to at least part of the first part of the audio signal; and determining the first section of the second part of the audio signal such that the first encoded audio signal and second encoded audio signal is within a defined encoding efficiency parameter. - View Dependent Claims (42, 43, 44, 45, 46, 47)

55. A method comprising:
-
decoding from a first part of an encoded audio signal a first audio signal; decoding from a second part of the encoded audio signal at least one indicator referencing at least a part of the first audio signal for generating a second audio signal; generating at least one further indicator dependent on at least one indicator, the at least one further indicator referencing at least a part of the first audio signal for generating a third audio signal; and combining the first, second and third audio signals to generate a decoded audio signal. - View Dependent Claims (56, 57, 58, 59, 60)
