UnverifiedMP3 encoding discards frequency components that are hard to perceive based on a psychoacoustic model, and decoding is only an algorithmic approximation, so the original sample values cannot be restored.72% similarUnverifiedMP3 audio encoding combines the Modified Discrete Cosine Transform (MDCT) with a psychoacoustic model to remove frequency bands that the human ear is insensitive to.71% similarUnverifiedMusicGen and Stable Audio use audio codecs to compress audio into discrete token sequences, then perform autoregressive generation in a manner similar to language models.69% similarUnverifiedEnd-to-end generation directly outputs audio files but creators cannot modify the internal structure, whereas symbolic-level generation outputs MIDI data, allowing creators to precisely control each note, velocity, and duration.67% similar
