Audio joiner FAQ
Something not covered here? Email hello@snipaudio.com.
Are my files uploaded to combine them?
No. This audio merger decodes, joins and encodes the files inside your browser. From this site, your browser downloads only this page, its two scripts and the small site icon. The page also loads Google Analytics, which counts visits and never receives your audio.
Can I use it as an MP3 joiner?
Yes. Add MP3 files, put them in order and export the combined audio as one MP3 at 128, 192, 256 or 320 kbps, or as WAV. You can also mix MP3 and WAV clips in one join.
What does the exported file sound like?
It is written at 44.1 kHz. If any clip is stereo, the result is stereo and mono clips play in both channels; if every clip is mono, the result is mono. With WAV and no fades or crossfade, the clips follow each other sample for sample. MP3 encoding adds a short stretch of silence at the very start of the file.
Is there a limit on files or length?
This page sets none. All decoded clips are kept in memory while you work, so many or long files need more memory and the practical limit depends on your device.
