Merge multiple WAV audio files
Join several WAV files end to end, in the order you choose, into a single continuous file. All files must have the same sample rate, the same number of channels and the same sample depth.
How it works
Handy for joining several audio takes into one continuous file: combining interview segments recorded separately, stringing voice messages together, or rebuilding a meeting recording that was split into several pieces. Import your WAV files, reorder them with the up/down arrows if needed, then click "Merge" to get a single downloadable file, in the order shown.
Why do my files need to have the same characteristics?
A WAV file encodes its samples at a specific sample rate, number of channels and bit depth. Directly joining samples from files with different characteristics would produce an unusable result (incorrect playback speed, distortion): the tool therefore checks that all files match before merging them, and otherwise shows a clear error naming the offending file.
Can I change the order of the files before merging?
Yes. Each file you add appears in a list with "↑" and "↓" buttons that let you move it up or down; the order shown in the list is the one used for the final merge.
Privacy: the merge runs 100% locally in your browser via WebAssembly — your recordings never pass through a server.
