未失真的 meaning in English

undistorted

After about two years " insisting and hard working , this goal set at the beginning has become true . the developed c54x general assembly program for g . 729 speech signal compressing algorithm has passed the tracking with more than 3 , 000 unitary standard measuring vectors . g . 729 speech signal compressing compiler using c54x general assembly program has been accomplished real - timely , and undistorted rebuilt speech signals have been obtained
因此本课题选用c54x的通用汇编语言编程实现g . 729语音压缩编码算法，调试并通过了统一标准测试矢量三千多帧，最终在5402开发实验板上实时实现了g . 729语音压缩编码器，获得未失真的重建语音信号。
