No. Our software product was designed to edit mp3 tags. During ID3 editing there are no any of these useful actions. If you need to cut large mp3 file, for example downloaded DJ mix, for Audio CD burning, highly recommended to open this mp3 file with wave form editor (SoundForge, CoolEdit, WaveLab, Nero Wave Edit, etc) and save each track as an individual *.wav file. Then add all these files to the burning project and burn Audio CD. Talking about mp3 mixing there are exist two answer: you need to mix mp3 in a real-time mode as a DJ - try TPlayer: or you need to get the mix as a mp3 file, and you will need to open in waveform editor, mix files or time fragments, and then again save as mp3 file with decreased quality. To cut, trim or join mp3 files simply find the appropriate mp3 file editor. The main requirement of these editors is the similarity of both joining mp3 files, such as the similar bitrate.
