Merging your audio files...
This tool joins multiple audio files together into a single file, one after another in the order you choose. Upload several clips, arrange them, and download the combined result as a single audio file.
Merging happens entirely in your browser using the Web Audio API — your files are never uploaded to a server.
If your files have different sample rates or numbers of channels (mono vs stereo), they're converted to match during merging so the result plays back correctly as a single continuous file. The output is produced as a WAV file, which preserves audio quality without additional compression — convert it to MP3 afterwards if you need a smaller file.
Once your files are uploaded, you can rearrange them into the order you want them to play — this determines the sequence in the final merged file. There's no limit to how many files can be combined, though more files and longer recordings increase processing time and memory use.
A common issue when merging audio from different sources — different recording sessions, different devices, or clips recorded at different times — is that each clip may have been recorded at a noticeably different volume. When merged, this can result in a final file that suddenly gets louder or quieter at each transition point, which is jarring for listeners. While this tool focuses on joining files together rather than adjusting levels, being aware of this in advance is useful: if possible, try to record all segments of a multi-part recording in similar conditions (same distance from the microphone, similar room) to minimise volume differences before merging.
For podcast-style content specifically, the order you arrange clips in matters beyond just "what comes first" — it shapes the listening experience. A common structure is: a short intro (often a brief jingle or introduction), the main content (which itself might be several segments if recorded across multiple sittings), and an outro (often with credits or a call to action). If your main content was recorded in several separate takes — for example, because you paused and resumed recording — merging those takes in the correct chronological order before adding the intro and outro at each end ensures the final episode flows logically from start to finish.
It's increasingly common for a single recording to be assembled from clips captured on different devices — a phone for one segment, a laptop microphone for another, a dedicated recorder for a third. Each device may produce files with different formats, sample rates, or channel configurations (mono vs stereo). This tool handles these differences automatically during merging, converting everything to a consistent format so the result plays back correctly as one continuous file — you don't need to manually convert each file to match before uploading.
If the merged file is larger than you need, use Audio Compressor to reduce its size, or Audio Converter to convert it to MP3. If you need to trim the combined result afterwards, Audio Trimmer can cut it down further.
There's no fixed limit, though more files and longer recordings increase processing time and memory use in your browser.
Yes, files in different formats (MP3, WAV, OGG, M4A) can be combined — they're decoded and converted to a consistent format during merging.
They're automatically converted to match during merging so the result plays back correctly.
The output is a WAV file. Convert it to MP3 afterwards using Audio Converter if you need a smaller file.
No, merging happens entirely within your browser.
