Psychoacoustic-based quantisation of spatial audio cues

The derivation of spatial cues representing source localisation information is a typical component of multichannel spatial audio coders. Efficient compression of spatial cues based on psychoacoustic localisation features is investigated. Results show that the proposed quantisation approach for spati...

Zusammenfassung:The derivation of spatial cues representing source localisation information is a typical component of multichannel spatial audio coders. Efficient compression of spatial cues based on psychoacoustic localisation features is investigated. Results show that the proposed quantisation approach for spatial cue compression achieves bit-rates of less than 6 kbit/s while preserving critical source localisation information.
