What is the max length of mp3 file?

Question

I was wondering if mp3 file has a sound length limit.

If there is some limit, I would like to know what it is.

Answer 1

As far as I know, there is no limit. There is nothing in a pure MPEG stream indicating length, which is what I would imagine where the limit would come into play. MPEG frames are lined up one after the other, with nothing linking them (except for the bit reservoir, if used).

Certain container formats may have other limits, but if you're talking about a plain MP3 file I think you are only limited by the file system and practical limits built into the software you're using to record and playback the file with.

For what it's worth, I've made MP3 files that are several weeks in length without any difficulty.
