About this tool
Combine voice notes, podcast segments or songs into a single file. Add 2 to 20 clips in any mix of MP3, WAV, M4A, AAC, OGG and FLAC, arrange them, choose an optional gap of silence, and our server joins them with FFmpeg. Clips with different sample rates or channel counts are converted to 44.1 kHz stereo so they play back seamlessly.

Frequently asked questions
Can I mix formats?
Yes. MP3, WAV, M4A, AAC, OGG and FLAC clips can be combined in one merge.
Is there a size limit?
All clips together must fit within the audio upload limit shown on the upload area.
Is Audio Merger private?
Your file is uploaded over an encrypted connection and processed in a private temporary folder on our server. The uploaded file and the result are deleted from the server as soon as processing finishes — whether it succeeds or fails — and the result is sent straight to your browser. If an upload is interrupted part-way, its temporary data is removed automatically within about 30 minutes. We do not keep copies.
