Split Audio Files Free Online — Two Files From One

Splitting an audio file is different from trimming it. Trimming keeps one section. Splitting produces two files — everything before a point and everything after. Fox Audio Trimmer handles this with two quick trim operations on the same source file. No software, no account, and each operation takes under 30 seconds.

What Makes Splitting Different From Trimming

When you trim an audio file, you keep one continuous section and discard the rest. When you split, the goal is to produce two (or more) separate files that together contain the full original audio.

Common split use cases:

• Dividing a long recording into Part 1 and Part 2 for upload limits
• Separating a full album into individual tracks
• Splitting a podcast episode into a free preview and a paid full version
• Dividing a DJ mix at the natural track boundaries
• Breaking a long lecture recording into shorter lesson segments

How to Split an Audio File in Two Using Fox Audio Trimmer

1. Decide your split point — the timestamp where File A ends and File B begins. Note this time before you start.
2. Open Fox Audio Trimmer in your browser and upload your audio file.
3. Create File A (the first half): Set start time to 0:00 and end time to your split point. Click Trim and download — this is your first file.
4. Upload the original file again — do not use the trimmed result.
5. Create File B (the second half): Set start time to your split point and end time to the full duration of the recording. Click Trim and download — this is your second file.

You now have two files that together cover the full original audio, split cleanly at your chosen timestamp.

How to Split an Audio File Into Three or More Sections

The same method extends to any number of splits. For three sections (A, B, C):

1. Trim 1: 0:00 to split point 1 → File A
2. Trim 2: split point 1 to split point 2 → File B
3. Trim 3: split point 2 to end → File C

Each trim uses the original source file as input — not the previous trimmed result. Keep the source file open in a separate browser tab so you can re-upload without searching for it each time.

For splitting a full album into many individual tracks, this approach is practical for up to 10-15 tracks. For larger collections, a desktop tool like Audacity (with its Export Multiple feature) or mp3DirectCut is more efficient.

Will the Split Files Sound Different From the Original?

Each split operation is a standard trim — the same quality rules apply. Downloading as WAV produces lossless output for each section. Downloading as MP3 involves a small re-encoding step per file, but at standard bitrates (128 kbps and above) the difference is inaudible.

If you are splitting a WAV source for professional use, download each section as WAV to preserve the lossless chain throughout the split workflow.

Frequently Asked Questions

What is the difference between splitting and trimming audio?

Trimming keeps one section and discards the rest. Splitting produces two or more complete files that together contain all the original audio. For splitting, run the trimmer twice on the same source file.

Can I split an MP3 into equal halves automatically?

Fox Audio Trimmer requires you to set the split point manually. To split exactly in half, find the total duration of the file, divide by two, and use that timestamp as the split point for both trims.

Can I split a podcast episode into two parts for upload?

Yes. Determine where you want Part 1 to end, run the first trim to get Part 1, then run the second trim starting at that point to get Part 2. Both files play as continuous audio.

Is there a free tool that splits audio automatically at silence points?

Audacity has a tool called Silence Finder and Export Multiple that can split a recording at silence gaps automatically. This is more efficient than manual splitting when you have many tracks to split, such as a full album with silent gaps between songs.
