Join audio clips locally in your chosen order. Add optional crossfades, preview the merged recording and download WAV or MP3 without uploading your files.
A crossfade overlaps time instead of adding silence between clips.
The second clip starts one second before the first ends: 5 + 5 − 1 = 9 seconds. Frame rounding can introduce a very small difference.
Use zero crossfade when preserving end-to-end timing is more important than a blended transition.
Combine audio clips into one continuous recording. Add at least two files, move them into the intended order and choose WAV or MP3 output. The browser decodes supported inputs and joins their sample data locally; input codec support depends on the browser.
A crossfade blends the end of a clip with the start of the next. The overlap is bounded by half the length of each neighboring clip so short clips are not completely consumed. Because the clips overlap, the merged duration is shorter than their summed source durations. Zero crossfade places them directly end to end.
The joining workflow uses a forty-four-point-one-kilohertz sample rate and at most two output channels. Mono is duplicated when combined with stereo; multichannel inputs use their first two channels. Compressed inputs are limited separately from decoded audio, because a small compressed file can expand substantially in memory. Listen across every transition and retain the originals.
Choose at least two supported audio files. You can add more files before starting the export.
Use the move-up and move-down buttons or remove clips that should not be included.
Set a crossfade between zero and five seconds. Choose uncompressed WAV or MP3 at 192 kilobits per second.
Press Join audio, listen to the completed recording and download it when the sequence is correct.
Shows numbered source files with keyboard-accessible reorder controls.
Overlaps adjacent clips using a bounded linear blend.
Offers an uncompressed file or a smaller lossy MP3 encoding.
Arrange short recordings into a single file for listening or transcription.
Join separate spoken sections and check the transitions before further editing.
Combine authorized audio clips with gentle crossfades when desired.
Add the MP3 files, arrange them and press Join audio. Choose MP3 output to download one merged recording.
Yes, when the browser can decode them. The decoded audio is resampled to a shared rate before joining.
Crossfades overlap neighboring clips. Disable the crossfade for a direct end-to-end sequence.
No. Sources are decoded and the result is encoded again. MP3 output uses lossy compression.
Compressed sound expands into samples during decoding. The tool limits decoded audio to 128 MB to bound memory use.
No. The tool supports at most two output channels and uses only the first two channels from a multichannel source.

Up to 20 clips, 50 MB each and 250 MB compressed total; decoded audio is limited to 128 MB. Files decode at 44.1 kHz. Mono is duplicated when mixed with stereo; multichannel inputs use their first two channels. Crossfades overlap adjacent clips and shorten the total duration. Supported input codecs depend on your browser.
