Hybrid predictive and parametric stereo coding for voice and audio communications

Guillaume Fuchs, Emmanuel Ravelli, Franz Reutelhuber, Eleni Fotopoulou

ICASSP 2025accepted

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…

Coding of fine granular audio signals using High Resolution Envelope Processing (HREP)

Florin Ghido, Sascha Disch, Jürgen Herre, Franz Reutelhuber, Alexander Adami

ICASSP 2017accepted

High Resolution Envelope Processing (HREP) is a new tool for improved perceptual coding of audio signals that predominantly consist of many dense transient events, such as applause, rain drop sounds, etc. These signals have traditionally been very difficult to code for perceptual audio codecs, parti…
