About this tool
An audio merger joins multiple sound files into a single continuous track. Add your files, drag them into the order you want, and export one seamless WAV or MP3 that plays each clip back to back.
Because the files may use different sample rates or channel counts, each one is decoded and resampled to a common format with your browser's OfflineAudioContext before being stitched together — so the join is glitch-free. All of this runs on your device; your audio never leaves your device and nothing is uploaded.
Use it to combine podcast segments, chain voice memos, assemble chapters of an audiobook, or build a single file from several exported clips.
Frequently asked questions
Which formats can I merge?
Any mix of browser-decodable files — MP3, WAV, M4A and more. They can have different sample rates and channel counts; each is resampled to a shared format automatically before joining.
What format is the merged file?
You choose WAV (lossless 16-bit PCM) or MP3 (lossy, at your bitrate). The output uses the highest sample rate and channel count found among your inputs so nothing is downgraded unnecessarily.
Can I control the order?
Yes. Files are joined from top to bottom, and the up/down arrows next to each file let you reorder them before merging.
Are my files uploaded?
No — every file is decoded, resampled, joined and encoded inside your browser, so your audio stays entirely on your device.
