介绍A律13折线的原理，很好很强大,非均匀量化参考好资料-A law introduced the principle of 13 line, nice and strong, non-uniform quantization good reference information

在GUI界面上，实现语音读取，描绘时域波形和频域波形，并进行采样和冲采样，最后进行非均匀量化（13折线）！-GUI interface, voice read, depicting the time-domain waveform and frequency domain waveforms, and sampling and washed samples, the final non-uniform quantization broken line (13)
