AI Technical Summary
Technical Problem
Existing audio data compression and decompression technologies are prone to introducing bit errors during transmission, leading to a decrease in the quality of reproduced audio signals. Furthermore, new technologies are difficult to interoperate with existing equipment, increasing latency and inapplicability.
Method used
Watermarks are generated by using specialized rounding operations to force the parity values of spectral line groups during audio data compression, and parity checks and multiple transmissions are used to detect or correct bit errors during decompression to maintain compatibility with existing standards.
Benefits of technology
It effectively reduces bit errors, improves audio signal quality, and interoperates with existing devices while reducing latency.

Abstract
描述了用于压缩音频数据的方法、设备、非暂时性计算机可读介质和系统。该技术涉及获得音频信号的数字化样本序列；使用数字化样本序列执行变换，以生成多条谱线；从多条谱线中获得一组谱线；以及量化该组谱线以生成一组量化值。量化该组谱线以生成该组量化值可以包括：对从该组谱线中选择的谱线执行专门的舍入操作；以及使用该专门的舍入操作将针对该组量化值计算出的组奇偶性值强制为预定奇偶性值。可以输出基于该组量化值的一个或多个数据帧。
