ComplexDec: A Domain-robust High-fidelity Neural Audio Codec with Complex Spectrum Modeling
Yi-Chiao Wu, Dejan Marković, Steven Krenn +2
Neural audio codecs have been widely adopted in audio-generative tasks because their compact and discrete representations are suitable for both large-language-model-style and regre…

ScoreDec: A Phase-preserving High-Fidelity Audio Codec with A Generalized Score-based Diffusion Post-filter
Yi-Chiao Wu, Dejan Marković, Steven Krenn +2
Although recent mainstream waveform-domain end-to-end (E2E) neural audio codecs achieve impressive coded audio quality with a very low bitrate, the quality gap between the coded an…
