Patent ID: 7894610

Claim:
Method for coding impulse responses of audio signals, wherein said impulse responses allow reproduction of sound signals corresponding to a certain room characteristic, comprising: using an MPEG-4 encoder to encode multiple successive MPEG-4 PROTO params fields of an MPEG-4 BIFS stream for transmission of one or more impulse responses associated with a coded audio signal as defined in the following steps: inserting into a first of said multiple successive MPEG-4 PROTO params fields information about the following MPEG-4 PROTO params fields by said MPEG-4 encoder, wherein said information comprises a number of the following MPEG-4 PROTO params fields to be used and a number of impulse responses to be transmitted; and inserting into said following MPEG-4 PROTO params fields for each of said impulse responses a length information of the impulse response and samples representing the impulse response.
