mp3DirectCut is a lossless editor for MP3 (and to a degree, MP2) audio files, able to provide cuts and crops, copy and paste, gain and fades to audio files without having to decode or re-encode the audio. By modifying the global gain field of each frame of MPEG audio, the volume of that frame can be modified without altering the audio data itself. This allows for rapid, lossless MP3 audio editing that does not degrade the data from re-encoding.
mp3DirectCut provides audio normalisation and pause (silence) detection, and can split long recordings into separate files based on cue points in the audio, such as those provided by pause detection. mp3DirectCut can also record audio directly to MP3 from the computer's sound card input.
All audio operations are performed using frame manipulation so, as such, mp3DirectCut is not a waveform editor. Audio clean-up such as click, hiss and noise removal is not possible.
