FAQ
Can I overlay two audio files online?
Yes — upload two files, choose when the second one starts and set each track's volume, then Vaxeho mixes them into one MP3.
Can I delay when the second track starts?
Yes — set an offset in seconds so Audio 2 starts partway through Audio 1 instead of at the same time.
Can I control the volume of each track separately?
Yes — Audio 1 and Audio 2 each have their own volume setting from 0% to 200%.
Which audio formats are supported?
You can upload MP3, WAV, M4A or OGG files. The mixed result is delivered as MP3.
Do I need to install software?
No — mixing happens on the server. You only need a browser.
