Frequently asked questions
How many files can I merge at once?
There is no fixed limit on the number of files. You can add many MP3, WAV, M4A, FLAC, or OGG tracks and join them into a single MP3. Each file can be up to 100 MB since processing happens in your browser.
What is crossfade for?
Crossfade is a smooth transition: the end of one track fades out while the next fades in, avoiding silence or abrupt cuts between tracks. You can set it from 0 to 3 seconds.
How do I reorder the tracks?
After adding files, use the ▲ ▼ buttons on each track to move it up or down. The order in the list is the play order of the merged file.
Are my files uploaded to a server?
No. TaoClip uses the Web Audio API + lamejs to decode and encode MP3 entirely in your browser. Your files never leave your device, and it is free with no watermark.
Which bitrate should I choose?
There are 5 levels from 96 to 320 kbps. 192 kbps is a good balance for most needs; 320 kbps gives the highest quality on good speakers.
How is this different from merging videos?
This tool only handles audio (MP3/WAV…). If you want to join multiple video clips, use TaoClip's Merge Video tool instead.
