3delite: Little review about the topic

'''MP3 Stream Editor''' is an all in one tool mainly for MP3s. Main advantage over other MP3 editors (or any other audio editor) is that you edit (MP2 & MP3) files without decoding and thus quality loss, graphicaly on a 3D sample display easely with a mouse. You have the option to repair the corrupted files also. Encode, re-encode, convert to WAV, cut and join MP3s, Tag MP3s with a professional frame based ID3v2 Tag editor, or even directly Record MP3/WAV/WMA/Flac streams. Burn them as AudioCDs or MP3 CD/DVDs, etc.

3delite: /* Editing */ MP3 Stream Editor is the best MP2/MP3 editor, not just cuts joins, but has full editing capabilities

'''MP2''' (sometimes also called Musicam) is short for '''MPEG-1 Audio Layer II'''. [[MP2]] files usually have an extension of .mp2 but sometimes .mpa is used instead. [[MP2]] has largely been superseded by [[MP3]] (MPEG-1 Audio Layer III) for file sharing and CD ripping, but it remains a dominant standard for audio broadcasting in Europe as part of the [[DAB]] digital radio and [[DVB]] digital television standards.

==Why Use MP2?==

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.

==Playback==

===Software Playback===

The MPEG-1 specifications say that a [[MP3]] decoder must be able to decode Layer I & II too, so any [[MP3]] player should play [[MP2]] files. MP2 support is probably even wider then [[MP3]] support since it is the audio format used in .mpg files too.

===Hardware Playback===

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.

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.

===Tagging===

[[MP2]] files can be tagged like [[MP3]] files.

==Conversion to MP3==

Remember that converting from [[MP2]] to [[MP3]] (or any other [[lossy]] format) will always result in a (small) loss of quality, so it's best to only convert when you have a really good reason to do so.

* you can simply use the [[LAME]] exe with the following commands using the command-line: lame.exe --mp2input -V 2 --vbr-new file.mp2 file.mp3
** the '--resample 44.1' switch could be added to the above to allow you to resample from a 48khz mp2 file to a 44.1khz mp3 file for example.
* if you prefer to use a GUI then use the following guide:

===What You Need===

* To convert [[MP2]] files to [[MP3]], you'll need to use a [[LAME]] compile that correctly accepts [[MP2]] input for decoding. [[LAME]] version 3.97 now does as standard, so no special ''lame.exe fixed for decoding'' is required. See the [[LAME]] page for instructions on how to get the ''lame.exe''

===How Do I Configure ALL2LAME and LAME?===

* First extract the ''All2Lame.zip'' file: it actually doesn’t have an installer, you just run the file.
* Next, move your ''lame.exe'' into the ALL2LAME folder. Your folder should now look something like:

[[Image:All2lame-dir.jpg]]

As long as ''lame.exe'' is in the same folder, that’s it! You don’t need to configure ALL2LAME anymore than that. Easy!

===How Does It Work?===

* Run ''all2lame.exe'' to start the program and do the following:
** Drag-drop the [[MP2]] file you want to convert into the white 'Files' area.
** Copy & paste the following line into the 'Switches' box: -V 2 --vbr-new
*** You might like to add the following command before the above switch to resample a 48khz mp2 file to a 44.1khz mp3 file: --resample 44.1
** Tick the '+' icon at the end of the 'Switches' box: this will save the command so that you won’t need to type it in again.

It should now look like this:

* It's now ready. Click the 'Encode' button and a window will pop up that looks like this:

[[Image:All2lame-cmd.jpg]]

* Congratulations, that means it's working! An [[MP3]] will be created in the same folder as the [[MP2]] file. You can whack that on your ipod and jump around like they do in the adverts.

==Editing==

Both [[MP3]] and [[MP2]] files can be losslessly cut and trimmed using:
* [[MP3DirectCut]]
* [[MP3Splt]]
* [[Pcutmp3]]
* [[MP3 Stream Editor]] Complete visual editor
