You cannot. MP3s are already very small compared to the size they are on a CD. The only way you can make it smaller is by re-encoding it for a lesser bitrate. To do this, I suggest downloading http://www.dll-files.com/dllindex/pop.php?lame_enc\nand http://audacity.sourceforge.net/download/

you can do it in iTunes.  when you have the song in your library, just right click on it and choose like song info or something.  then just look through the menu, and there should be a start and end time.  it you only want half, put in how long you want the song to play for until it stops.  say if its a 3 minute song, put 1:30  and it will end halfway.

1. Select Insert > Movies and Sounds > Sounds from File.\n2. Browse to the folder where your song is. Select it and click OK.\n3. A message will come up asking if you want to play the sound automatically. Click yes (unless you don't want it to start until you click it or do something else, in which case, click no).\n4. Right click on the sound (it looks like a blue speaker) and select Custom Animation.\n5. In the Task Pane, you'll see your song listed (and any other objects you have animated). Click the drop-down arrow for your song and select Effect Options.\n6. Under Stop Playing, select After ___ slides.

There are two ways:\n1. Use any audio editing software, such as iTunes or Cool Edit Pro. In iTunes it's called 'Sound Check'. It's right on the: Edit - Preferences - Playback, and click on the 'Sound Check' icon. This will adjust the volume ABOUT the same level.\nOn Cool Edit Pro it's located in: Edit - Group waveform normalize, then you can follow the instruction inside.\nThis will also adjust your music at ABOUT the same level.\nThe key word was ABOUT the same level. This method is only practical, but sometimes some songs is still louder than the other, in this case you should go with option...\n\n2. Trust your ears.\nAdjust every track in your CD manually using the most sophisticated sound check ever, your ears!\nThis method will take some time, but it is worth it. You must be patient. Cool Edit Pro is my weapon of choise when it comes to sound editing.\nGo to: Effects - Amplitude - Amplify - Constant Amplification; Then adjust the volume track by track, using your ears as a measuring tools.\n\nGood luck!

I don't think there is a good way. You'd need to write code to filter the tone out of the microphone data, figure out the frequency, and give feedback to the user. It can be done, but it would be way more trouble than it's worth in any language I can think of. IMO you should just put up the $20 for a pocket tuner.

you can do a search on programs you can download.  Usually they give you a free trial period or you can convert a certain number of songs.

Try Audacity, http://audacity.sourceforge.net/ and you will also need the LAME MP3 encoder, it's listed on the same site.

when you rip cds to mp3, some of the software has the option to "Normalise it". what it does is basicly try to put all song at the same sound level, so when you play them, no song sounds too low or too high.

You have to do it manually with a sound editting tool It would take hours and the sound quality will be crap afterwards.
