In real-time teleconferences over mobile networks, cross-talk can significantly impact the performance of parametric stereo codecs, particularly at low bitrates. When multiple speakers overlap, stereo quality can be improved by independently encoding the left and right channels, especially when inte…
Stereo and multi-channel audio coding for mobile communication applications is challenging due to bitrate, latency and computational complexity constraints. To address these constraints, a novel MDCT-based stereo coding scheme is introduced. A key feature of this scheme is the broadband inter-channe…
The transmission of stereo audio in voice calls helps to improve immersion and user experience. However stereo coding has primarily been studied for broadcast or streaming applications. To extend the capabilities of 3GPP EVS, a hybrid stereo coding scheme combining predictive and parametric coding i…
