MP3 is a digital audio encoding format, in which audio files are compressed to reduce the amount of data (i.e. shrink the file size), without losing sound quality in the ears of most listeners. The standard procedure of editing an MP3 file involves several steps: decompression of the file, editing, and re-encoding to MP3. The decompression and re-encoding process typically results in a significant loss of quality. mp3DirectCut is a freeware audio editor and recorder that can work with compressed MP3 files. It allows you to cut, copy, and paste audio bits or change the volume without decompressing the audio file. In other words, you can edit your MP3 files without a loss of quality. Moreover, you can record MP3s and auto-detect pauses to cut and ID3 tag a file. The Interface mp3DirectCut has a clear interface, which provides easy access to all key features. Editing and playback buttons sit at the bottom of the window, navigation in the middle, topped by the MPEG audio data waveform
