Join audio files in order
Join several audio files into one in the order you choose, for example to combine voice notes or tracks, and save it as MP3, Opus or WAV.

- No upload
- Check before download
Files and content stay on this device. Aggregate action counts are sent only with your separate consent. MP3/Opus re-encoding loses original tags and may increase size. WAV is PCM. 32 MB/file, 120 seconds total, mono/stereo; 5 files for ordered concatenation. Speed changes pitch.
Join audio files in order
- Prepare the input
Choose up to five compatible mono or stereo files and arrange them in the order shown before you create the result. Check the total decoded duration, sample rate and channels. Joining puts the recordings one after another and doesn't mix them together.
- Try the worked example
A two-second clip followed by a three-second clip gives five seconds of joined PCM content, with the first clip before the second. Select WAV to check the sample timing directly. Lossy formats can add codec padding.
- Check and save
Listen at every join and check the final end before you save. The tool doesn't promise a crossfade or silence removal. Reordering or replacing inputs invalidates an old result, so keep the original files and download only the current output.
Questions
Does joining make the clips play simultaneously?
No. They are joined one after another in order. Mixing tracks, balancing levels and crossfading are separate operations that this job doesn't provide.
Why are individually valid files refused together?
The combined decoded duration must fit within 120 seconds, and the audio formats must be compatible. A mismatch in sample rate or channels, or the total limit, can reject a batch even when each file works on its own.
Will original MP3 tags and packets be preserved?
No. This workflow works with decoded PCM and encodes the output you choose. Tags are dropped, and a compatible duration doesn't mean the compressed audio is byte-for-byte identical. Keep your originals.
