[1] [2] [3] MP3 Surround is backward compatible with standard MP3. [1] [4] The data overhead is 16 kbit/s, which allows for file sizes similar to standard stereo MP3 files. The file size is approximately 10% larger than that of a typical MP3 file. The current evaluation encoder is licensed for personal and non-commercial uses.

[citation needed] On earlier systems that only support the MPEG-1 Audio Layer III standard, MP3 files with a bit rate below 32 kbit/s might be played back sped-up and pitched-up.

Kemp deliberately placed the tag data (which is demarcated with the 3-byte string TAG ) at the end of the file as it would cause a short burst of static to be played by ...
