How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Audiodec: An Open-Source Streaming High-Fidelity Neural Audio Codec (2023, background): “Audio codec techniques have been applied to a variety of real-world applications such as secure communication [1, 2], low-cost mobile and internet communications [3, 4], and live videos and music streamings [5].”
Wavenet Based Low Rate Speech Coding (2017, background): “Speech coding found its ﬁrst major application in secure communications, e.g., [1], and later enabled low-cost mobile and internet communications, e.g., [2, 3, 4].”
Improving Opus Low Bit Rate Quality with Neural Speech Synthesis (2019, background): “Examples are linear predictive vocoders [1, 2] or sinusoidal coders [3, 4].”
Robust Low Rate Speech Coding Based on Cloned Networks and Wavenet (2020, background): “This resulted in vocoders that use linear-prediction based features for the spectral shaping of a source signal that is generated based on pitch and periodicity parameters, e.g., [6].”
