How to use the mp3 joiner
- Choose your filesPress "Choose files to join" and pick two or more files. They appear in a list.

- Join and savePress Join files. The joined track opens in the editor; press Export to save one MP3.
You can also drop several files on the editor at once.
Join MP3 files in the order you want
Echoly joins two or more audio files into one: chapters of a story, parts of a recording that stopped in between, or songs for a function. Choose the files, arrange them in a list with the up and down arrows, and press Join. They become one track that you can still edit before saving.
Different formats? No problem
You can mix MP3, M4A, WAV, OGG and FLAC in one list, and even the sound of an MP4 video. Files with different sample rates are converted automatically, and if any file is stereo the joined track is stereo too.
Gaps and smooth joins
Add a short silence between files (half a second to two seconds) so songs do not run into each other, or leave no gap for a continuous recording. "Smooth joins" adds a tiny fade at every join so you never hear a click.
After joining
The joined track opens in the editor. Each join is easy to find on the waveform; you can cut extra silence, add a fade, raise the volume of a quiet part, and finally export as one MP3, WAV, FLAC or OGG file.

Questions about the mp3 joiner
How many files can I join?
There is no fixed limit. Ten or twenty songs work fine on a computer; on a phone, very long results (over an hour) may be slow because everything happens on the device.
Can I change the order after choosing the files?
Yes. Use the ▲ and ▼ buttons in the list, or ✕ to remove a file, before pressing Join.
Will the joined MP3 lose quality?
Each file is decoded and saved once. Export at 192 or 320 kbps MP3, or as FLAC for no loss at all.
Can I add a file in the middle of my audio?
Yes. Place the cursor where it should go and choose File → Insert a file at the cursor.
