 ==Why Use MP2?==
-[[MP2]] is the low-complexity older brother to [[MP3]] and is usually not as efficient as [[MP3]] in keeping sound info in any music file so that for lower bitrates [[MP3]] should be superior to MP2. However, it has its advantages. For example, bitrates at 224kbps and higher should sound better with [[MP2]] because of its low complexity in comparison to [[MP3]]. It is also the more robust format in noisy environments and that is the reason why [[MP2]] is used as the audio format in [[DAB]] and [[DVB]] (all digital broadcasts by satellite, digital cable, etc.) all over the world.
+MP3 should provide superior sound quality to [[MP2]] at the same bitrate so there is no reason to use it for CD ripping or encoding from analogue sources. However since [[MP2]] is the audio format used in DAB and DVB all over the world, the best way to record from these is to use some method to capture the [[MP2]] audio stream straight to disk (e.g. using PCI DVB card). An [[MP2]] created like this will provide a ''perfect'' copy of the original broadcast.

 If your hardware player only plays [[MP2]] files with an .mp3 extension it might be worth asking the manufacturer if this could be fixed with a firmware update. Try to remember to rename it back to .mp2 before sharing it again, as there are some technical differences between [[MP2]] and [[MP3]] that mean things like [[Replaygain]] only work with real [[MP3]] files. Using a double extension like (e.g. radio_mix.mp2.mp3) might help you remember.

 In theory all hardware [[MP3]] players should be able to play [[MP2]], but in practice this does not always seem to be the case. Some have no problems playing [[MP2]] files (even if this isn't mentioned anywhere in the players specifications), some will only play them if you give it an .mp3 extension, and others won't play them at all.
