Real-Time Packet Loss Concealment With Mixed Generative and Predictive Model
Jean-Marc Valin, Ahmed Mustafa, Christopher Montgomery +4
As deep speech enhancement algorithms have recently demonstrated capabilities greatly surpassing their traditional counterparts for suppressing noise, reverberation and echo, atten…
Perceptually-Driven Video Coding with the Daala Video Codec
Yushin Cho, Thomas J. Daede, Nathan E. Egge +5
The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video…
Daala: Building A Next-Generation Video Codec From Unconventional Technology
Jean-Marc Valin, Timothy B. Terriberry, Nathan E. Egge +4
Daala is a new royalty-free video codec that attempts to compete with state-of-the-art royalty-bearing codecs. To do so, it must achieve good compression while avoiding all of thei…
Daala: A Perceptually-Driven Still Picture Codec
Jean-Marc Valin, Nathan E. Egge, Thomas Daede +2
Daala is a new royalty-free video codec based on perceptually-driven coding techniques. We explore using its keyframe format for still picture coding and show how it has improved o…
Improved Noise Weighting in CELP Coding of Speech - Applying the Vorbis Psychoacoustic Model To Speex
Jean-Marc Valin, Christopher Montgomery
One key aspect of the CELP algorithm is that it shapes the coding noise using a simple, yet effective, weighting filter. In this paper, we improve the noise shaping of CELP using a…
Low-Complexity Iterative Sinusoidal Parameter Estimation
Jean-Marc Valin, Daniel V. Smith, Christopher Montgomery +1
Sinusoidal parameter estimation is a computationally-intensive task, which can pose problems for real-time implementations. In this paper, we propose a low-complexity iterative met…
