Action

Browser-side processing exports PCM WAV. The size-reduction option converts to mono 22.05 kHz PCM, which can reduce WAV size but is not MP3 encoding. Large files may exceed browser memory.

HOW IT WORKS

Simple, transparent tools

Paste or upload

Check a link's format, extract audio from a video file you provide, or choose local audio files.

Process locally

Extraction and audio editing run in your browser. Your local files are not uploaded to this server.

Download real output

Download appears only after processing succeeds. Output type depends on the selected tool and browser support.

GUIDE

How to use the Audio Merger

Combine several audio files you own into one WAV file, in the order you selected them. Files with different sample rates or channel counts are resampled to the highest values among the inputs.

Steps

Choose two or more audio files you own or are authorised to use (30 MB each). The merge order is the order you selected them.
Make sure Merge files (WAV) is selected, then select Process audio.
Preview the combined result and check that its duration equals the sum of the inputs.
Download the merged WAV file.

Supported inputs and outputs

Inputs: multiple audio files your browser can decode (MP3, WAV, M4A, and similar).
Output: one PCM WAV whose duration is the sum of the input durations.
Mixed inputs are resampled to the highest sample rate and channel count found among the files.
Files are processed on your device and are not uploaded by this tool.

Troubleshooting

If one file fails to decode, the whole merge fails with a message. Check each file individually, then try again.
If the order is wrong, select the files again in the order you want — the merge follows selection order.
Very large selections may exceed browser memory. Merge fewer or smaller files at a time.

Frequently asked questions

Can I reorder files after selecting them?

Not in this tool. The merge order is your selection order, so select files in the order you want them joined.

What happens with mixed sample rates?

Everything is resampled to the highest sample rate and channel count among your files, so the result plays consistently.

Is the output MP3?

No. The merged output is PCM WAV.
