是一个集声音编辑，播放，录制，和转换的音频工具，体积小巧，功能却不弱。可打开的音频文件相当多，包括WAV, OGG, VOC, IFF, AIF, AFC, AU, SND, MP3, MAT, DWD, SMP, VOX, SDS, AVI, MOV, APE等音频文件格式，你也可以从 CD 或 VCD 或 DVD 或其它视频文件中提取声音。内含丰富的音频处理特效，从一般特效如多普勒、回声、混响、降噪到高级的公式计算(利用公式在理论上可以产生任何你想要的声音)，效果多多。-Is a sound editing, playback, recording, and conversion of audio tools, small, functional but not weak. To open a significant number of audio files, including WAV, OGG, VOC, IFF, AIF, AFC, AU, SND, MP3, MAT, DWD, SMP, VOX, SDS, AVI, MOV, APE format audio files, etc., you can also from the CD or VCD or DVD or other video files to extract the sound. Contains a wealth of audio processing effects, from the general effects such as Doppler, echo, reverb, noise reduction to high-level formula (using the formula in theory can produce any sound you want), the effect of a lot.
