Filter ringtone frequencies as some reputedly blow fragile phone speakers!
Also, remove stereo tracks as most phones are mono (or combine stereo
tracks).
To create your own free ringtones:
IMPORT MP3:
1. Locate the desired MP3 song on your Windows computer hard drive
2. Start Audacity 1.2.6 freeware (
http://audacity.sourceforge.net)
3. Import the desired MP3 using "Project > Import Audio"
CHOOSE MP3 SNIPPET:
1. Using left click, play, & stop, roughly choose the desired snippet
2. With nothing playing, left click near the middle of your selection
3. "View > Zoom to Selection" to get rough start & end points
Note: You want only about 25 to 30 seconds showing in your window
DELETE THE REST:
1. With nothing playing, left click near the beginning of your selection
2. Press "Edit > Select > Start to Cursor" & then "Edit > Delete"
3. With nothing playing, left click to set the cursor at the snippet end
4. Press "Edit > Select > Cursor to End" & then "Edit > Delete"
Note: Aim for a ringtone of about 20 seconds (25 seconds maximum)
REMOVE STEREO:
1. Set "Edit > Preferences > File Formats > Bit Rate: 32 kbps" > OK
2. Locate the arrowed pulldown on left to the select "Split Stereo Track"
Note: This pulldown is hard to find; it's not on the pulldown menus;
it's on the left; there is an X to the left, then the song title,
then the downarrow has the pulldown for "Split Stereo Track".
3. Hit the "X" for one of the now-split tracks to delete that one track
4. Select the one track (ctrl+A) & press "Project > Quick Mix"
Note: That creates an empty second track; I'm not sure why it's needed.
FADE & FILTER:
1. Set the "Project rate:" at the bottom left to 22050 Hz (22.05 kHz)
3. Sweep-select the last two seconds & hit "Effect > Fade Out"
4. Ctrl+A, choose "Effect > High Pass Filter > 150 Hz"
Note: This is EXTREMELY IMPORTANT to protect your phone speaker!
5. Amplify by selecting ("ctrl + A) & pressing "Effect > Amplify"
Note: Turn "Allow Clipping" off and only amplify enough not to clip;
do not allow the "New Peak Amplitude" to rise above 3 dB.
EXPORT:
1. File > Export selection as MP3 & give it a name.
2. The filename (not counting the .mp3) cannot exceed 32 characters.
3. The file size should be less than 100 KB (average around 80 K
.
This creates a good loud 20 second mono ringtone at the right bitrate and
with the right frequencies so as not to destroy your telephone speaker.
How you then get this ringtone from your computer into your telephone is by
one of the following methods (in decreasing order of desireability):
1. Save directly onto a microSD (or whatever memory card fits in the phone)
2. Transfer from the PC to the phone via a tethered USB data cable
3. Transfer from the PC to the phone over the air (10 meters) via bluetooth
4. Email it to your phone (if you have an unlimited data plan)
5. Email SMS it to your phone (if you have an unlimited texting plan)
6. Upload it to a website (generally a ripoff) which will message it back
to your phone (not recommended).
