Abstract:
A system for producing an encoded digital audio recording has an audio encoder that encodes a digital audio recording having a number of audio channels or audio objects. An equalization (EQ) value generator produces a sequence of EQ values which define EQ filtering that is to be applied when decoding the encoded digital audio recording, wherein the EQ filtering is to be applied to a group of one or more of the audio channels or audio objects of the recording independent of any downmix. A bitstream multiplexer combines the encoded digital audio recording with the sequence of EQ values, the latter as metadata associated with the encoded digital audio recording. Other embodiments are also described including a system for decoding the encoded audio recording.

Claim (Index 1):
A system for producing an encoded digital audio recording having a plurality of audio channels or audio objects, comprising:\n an encoder to encode a digital audio recording having an original plurality of audio channels or audio objects, to produce an encoded digital audio recording; an equalization (EQ) value generator to produce a sequence of EQ values which define EQ filtering that is to be applied to a specified EQ group of one or more of the original audio channels or audio objects, independent of downmix and upon decoding the encoded digital audio recording; and a bitstream multiplexer to combine a) the encoded digital audio recording with b) the sequence of EQ values including an indication of said EQ group, the latter as metadata associated with the encoded digital audio recording.
