[Paper 리뷰] ScoreDec: A Phase-Preserving High-Fidelity Audio Codec with a Generalized Score-based Diffusion Post-Filter
ScoreDec: A Phase-Preserving High-Fidelity Audio Codec with a Generalized Score-based Diffusion Post-FilterWaveform-domain end-to-end neural codec은 low-bitrate의 coding이 가능하지만 여전히 natural audio와의 품질 차이가 존재함해당 neural codec의 성능을 향상하기 위해서는 GAN training이 필요하지만, original phase information preserving을 방해한다는 문제가 있음ScoreDecGAN training에서 original phase preserving을 위해, complex spectral domain에서 score-base..
