Tips for Best Results
- The last segment will be shorter if the audio duration is not evenly divisible by the segment length
- Segments are created using stream copy (no re-encoding) for faster processing
- All segments maintain the original audio format and quality
- Processing time depends on the number of segments and file size
- You can download individual segments or all segments as a ZIP file
