mp3DirectCut is a lightweight, free audio editor designed for fast and lossless editing of MP3 and AAC files. Developed by Martin Pesch, it enables users to cut, crop, split, and join audio tracks without the need for re-encoding, thus preserving the original audio quality. (Audacity Forum, mpesch3.de)
🔧 Key Features
- Lossless Editing: Perform non-destructive edits like cut, copy, paste, and volume adjustments directly on MP3 and AAC files without decompressing them. (FOSSHUB)
- Volume and Fading Controls: Adjust volume levels, apply fades, and normalize audio using the global gain field of MPEG audio frames. (Audacity Forum)
- Direct MP3 Recording: Record audio directly to MP3 format using ACM or LAME encoders, capturing input from your sound card. (Wikipedia)
- Cue Sheet and Pause Detection: Automatically detect pauses to split long recordings and support cue sheets for track division. (Wikipedia)
- Batch Processing: Edit multiple files simultaneously, streamlining repetitive tasks.
- Visualization Tools: Utilize fast MPEG visualization, VU meters, and bitrate displays for precise editing. (FOSSHUB)
- Tag Editing: Edit ID3v1 tags to manage metadata like track titles and artist information. (Wikipedia)
💡 Limitations
- Frame-Based Editing: Edits can only be made at the start of MP3 frames, limiting precision to approximately 1/38 of a second. (Wikipedia)
- Volume Adjustment Steps: Volume changes are limited to 1.5 dB increments due to the manipulation of the global gain field. (Wikipedia)
- ID3v2 Tag Support: The application does not support ID3v2 tags; it only handles ID3v1 tags. (Wikipedia)
- AAC Editing Requirements: Editing AAC files requires additional libraries, such as
libfaad2.dll, and does not support AAC within MP4 containers without prior extraction. (Wikipedia)
🖥️ System Compatibility
- Operating Systems: Compatible with Windows 95 through Windows 10. (Wikipedia)
- Linux Support: Can be run on Linux systems using Wine.
- Portable Version: Offers a portable mode that doesn’t require installation or modify the Windows Registry. (Wikipedia)
