Shorten the MP3 to Ring Tone Length

1.  Start Audacity and open the EDIT menu. 2.  Choose Preferences, and open the File Formats tab.
3.  Near the bottom of the dialog box, adjust the bit rate to what works for your phone.  Choose 128 if you are not sure.  Click OK. 4.  Click on the FILE menu and choose Open. 5.  Browse to the folder where your MP3 is saved.  Double click the file name, or highlight it and click Open.
6.  Audacity will import the mp3 and display the sound frequencies as above. 7.  Hit the PLAY button (green arrow) and decide how much of the song you want to use.  20 to 30 seconds is plenty.  Use the timeline above the graph as a guide. 8.  You'll need to establish a beginning and and end point by clicking with the mouse.  Make sure the cursor is in the  "select" mode (looks like I )  It should default to this , but click the button in the upper left corner of the toolbar if not. 9.  If your ring tone will start at the beginning of the song, that is already selected as the default "start" point.  Let the song play to where you want the ring tone to end, and hit the PAUSE button.
10.  Where you paused there should be a green arrow on the timeline pointing downward. 11.  Put the cursor inside the graph area, right underneath the center of that arrow, and double click.  A line should appear from top to bottom. 12.  Put the mouse cursor near that line and a hand should appear with a finger pointing to the left.   Left click and hold, and drag to the left to the ZERO point to select that part of the song.  It will turn a darker gray.  Hit the STOP button. (very Important  -- don't skip this step). 13.  At this point if you are unsure if you got the exact portion of the song you wanted, hit the STOP button, then hit REWIND, and PLAY again.  If you want to choose a section of the MP3 that does NOT start at the beginning of the song, continue on to step 14.  Otherwise, skip to step 19. 14.  If you want your ring tone to begin somewhere in the middle of the song, PLAY to where you want it to start and hit PAUSE.  Then double click inside the graph area to establish the "start" line. 15.  Choose PROJECT on the menu bar.  Then choose Add Label at Selection to mark that spot.   A red flag will appear in the label track at the bottom. 16.  Hit STOP, then PLAY to resume the song.  When it gets to your end spot, hit PAUSE. 17.  Once again double click inside the graph under the green arrow, to establish the end line. 18.  Hover the mouse over that end line until it changes to a finger pointing left.  Click and drag to the red flag to select your portion of the song.  Hit the STOP button.
19.   With your portion of the song selected (dark gray), Click on FILE, and choose Export Selection as MP3.   Name the file whatever you like and save to a folder of your choice. 20.  Play your ring tone to see how you did.
