说明：  1.0支持系统的录音多种格式,有一定的延时,没有过滤杂音功能. 2.0已取消支持系统的录音多种格式,使用PCM采集数据G711A压缩格式 (8000HZ单声道16位格式录音每秒以8K完成数据,16000HZ单声道 16位格式录音每秒以11K完成数据,音质相当好),延时降低到最小 100-500MS以内,不会随时间增加而增加延时(如果是说话测试一直保持 200MS的延时,如果是用播放歌曲来测试,有自动校正延时功能,恢 复成200MS的延时,恢复过程中不会中断歌曲的播放,只是小小加快唱 歌的速度,听觉不会觉察出来),加入了过滤杂音功能.
(1.0 Support System for recording a variety of formats, has a certain degree of delay, there is no noise filtering feature has been canceled .2.0 support system recordings in multiple formats, the use of PCM data collection G711A compression formats (8000HZ mono audio format 16-per-second to 8K complete data, 16000HZ mono 16-bit format to 11K per second, recording the completion of data, sound quality quite good), delay to minimize 100-500MS within, will not increase with time delay (if it is to speak the test has remained 200MS the delay, if it is used to play songs to test, have automatic delay correction function, the restoration of 200MS into the delay, the recovery process will not be interrupted play songs, but little to accelerate the pace of singing, hearing is not perceived by ), joined the noise filtering function.)
