- Audio takes up a lot of space when it is digitized. It is necessary to solve the compression problem of audio signal. Compression has no negative effect on sound quality. A: 正确 B: 错误
- MPEG audio compression takes advantage of__________ constructing a large multi-dimensional lookup table to transmit masked frequency components using fewer bits.
- Which of the following are functions that are often provided by an ITSP but are not typically provided by the PSTN？（） A: QoS B: call setup and teardown C: call routing D: call supervision E: audio signal compression
- The premise of data compression is that there is more or less redundant information in the data, and for multimedia information such as video and audio, humans can use their own perceived redundancy (distortion) characteristics to achieve a higher compression ratio. ( )
