Audio Codec Enhancement with Generative Adversarial Networks (2020, methodology): “For example, quantization noise in the quiet region prior to a transient event in a decoded audio signal can be perceived as pre-echoes [1],[2] at the attack portions of”
Introduction to Digital Speech Processing (2007, background): “These coders are widely deployed in MP3 and AAC players and for audio in digital television systems [120].”
Temporal Noise Shaping with Companding (2018, background): “There are two very successful control strategies for reducing pre-echo artifacts [1].”
Exploiting time-frequency patterns with LSTM-RNNs for low-bitrate audio restoration (2019, background): “This is commonly due to the fact that the amount of bits required to keep the amplitude of quantization noise below the masked threshold is insufﬁcient, leading to audible noise, so-called spectral holes, or due to signal bandwidth reduction [5, 56].”
