Demos still go out as MP3 because MP3 never fails: every phone, browser, car and venue laptop of the last two decades plays it without a plugin. From an uncompressed AIFF, the encoder here produces a 320 kbps MP3, the format's ceiling, at about a tenth of the source size. Musicians care where session audio travels, and here it travels nowhere: the encode is done by your browser, on your computer, with trim if you need it.
Questions
Why MP3 rather than M4A for a demo?
Reach. M4A sounds slightly better per bit, but MP3 is the one format you never have to think about. For a demo going to unknown players, that certainty wins.
What bitrate should a demo use?
320 kbps unless the mail system objects to the size; 192 kbps stays clean for most material and is a third smaller.
Can I cut the count-in before converting?
Yes. Start and end trim points are under More options, in seconds.
Does any audio get uploaded?
No. The conversion is entirely local; verify it in your browser's network tab if you like.
