Its shows when frequency cross-section of the codec leads to the loss of high-frequency part of the sound. Then codec with the biggest frequency range is the codec that provides the nearest reproduction value of the full frequency spectrum in comparison to non- compressed WAV with the range of approximately 22 kHz."

2023年4月3日 · Opus is the best generic lossy audio codec. It's arguable when AV1 will/has overtake H.265 as the "best" generic lossy video codec.
