Split Audio Files Online — Divide MP3, WAV, FLAC into Parts
Split any audio file into equal parts or by custom duration. Download each segment separately.
What Is Audio Splitting?
Audio splitting is the process of dividing a single long audio file into multiple shorter segments. Unlike audio trimming (which extracts one specific portion), splitting divides the entire file into pieces, giving you every part of the original. This is useful for distributing large files, creating chapter-based content, or preparing audio for platforms with duration limits.
Why Split Audio Files?
- Email and messaging limits — Most email services limit attachments to 25 MB. Splitting a long recording into parts makes it easy to share via email or messaging apps.
- Platform upload limits — Social media and podcast platforms often have maximum duration limits. Split long recordings to fit within these limits.
- Chapter-based content — Divide a long audiobook or lecture recording into individual chapters for easier navigation.
- Backup and archiving — Splitting large audio files into smaller chunks makes them easier to back up to cloud storage with file size restrictions.
- Easier editing — Working with shorter segments in a DAW is often more efficient than editing one very long file.
How Splitting Works
Upload your audio file and choose how many equal parts to split it into, or specify the duration of each segment. The tool calculates the split points and creates individual audio files for each segment. All segments maintain the original audio quality and format. The last segment may be slightly shorter than the others if the file does not divide evenly.
Splitting for Podcasts and Broadcasts
If you record a long interview or show and need to create multiple episode files, the Audio Splitter is perfect. Upload the full recording, set the number of parts, and download each episode segment. Combine this with the Audio Trimmer to fine-tune the exact split points after the initial division.
Output Quality
Splits are performed without re-encoding for WAV and FLAC files, preserving perfect audio quality. For MP3 files, boundary frames are handled cleanly with minimal impact on quality. All output files retain the same format and settings as the original.
How it works
- Upload your audio file (MP3, WAV, FLAC, OGG, AAC, or M4A).
- Enter the number of equal parts to split into, or specify segment duration.
- Click Split Audio to process the file.
- Download each individual segment as a separate file.
