Abstract
Deep-learning based methods have shown their advantages inaudio coding over traditional ones but limited attention hasbeen paid on real-time communications (RTC). This paperproposes the TFNet, an end-to-end neural audio codec withlow latency for RTC. It takes an encoder-temporal filtering-decoder paradigm that seldom being investigated in audiocoding. An interleaved structure is proposed for temporalfiltering to capture both short-term and long-term temporaldependencies. Furthermore, with end-to-end optimization,the TFNet is jointly optimized with speech enhancement andpacket loss concealment, yielding a one-for-all network forthree tasks. Both subjective and objective results demonstratethe efficiency of the proposed TFNet.
