These are the steps that I used to use for converting MP3's to ringtones for my Sprint PCS phone (free!). This was a really popular post on my surfing.textamerica.com site before TA shutdown. I no longer use Sprint (on AT&T waiting for my iPhone), but can probably help if you run into a problem with these steps.
A. Convert MP3 to WAV
1. I have been using JetAudio to convert (Other apps, like WinAmp work too):
http://www.download.com/3000-2167-10013740.html
2. Locate the MP3 in Windows Explorer
3. Single right click on the file and select "JetAudio | Convert with JetAudio"
4. From the "Output format" drop-down select: WAV
5. Click the "Config..." button
6. Click the "Select WAV Format..." button
7. Select "PCM" for the "Format" drop-down
8. Select "8,000 kHz, 16 Bit, Mono" for the "Attributes" drop-down
9. Click "OK"
10. Click "OK" again
11. Click the "Start" button
NOTE: By default the WAV file will be in the same folder as the source MP3 file.
B. Edit length to 30 seconds
NOTE: I'm using the Windows Sound Recorder to shorten the length
1. Click "Start" and select "Run..."
2. In the "Open" field type:
sndrec32
3. Click the "OK" button
4. From the main menu select "File" and click "Open..."
5. Double click on the WAV you created above
6. Cut out sections of song with "Edit| Delete Before/After Current Position"
NOTE: If the volume of the ringer is too low, the volume can be increased:
- From Sound Recorder's main menu, select 'Effects'
- Click on 'Increase Volume (by 25%)'
7. Save the shortened file with the "File | Save As..." option
8. Make sure the Format is: PCM 8,000 kHz, 16 Bit, Mono
NOTE: Use the "Change..." button if it's not correct
NOTE: Any other setting and the end result will sound like a chicken
C. Convert the WAV to smaller QCP format (Qualcomm PureVoice file)
1. Download, install and open the GCD Creator from:
http://www.sprintusers.com/downloads/gcdcreator/
2. Click the "WAV to QCP" button on the left
3. Click the ">" button
4. Browse to and double click on the altered WAV file created above
5. Click the "Convert WAV" button
NOTE: The QCP file is created in the same folder as the source WAV
D. Upload file to your Sprint PCS phone
1. Open your browser to: http://www.sprintusers.com/focus/
2. Click the browse button, navigate to your desktop
3. Double click on the .QCP file you created
4. Give it a title
5. Type in your Sprint PCS phone number
6. Click the "Send to Phone" button
E. Load on your Sprint PCS phone
1. You will get a "New Text" message
2. View the message
3. Click the "Go" button
4. It will say that this is "Not trusted content", select "Continue" radio button
NOTE: It downloads to phone
5. On the "Confirm" dialog select the "Use" radio button and click "OK"
From here it will exit the browser and you can play, set as or erase.
If the ringer volume is too low compared to your other ones, the volume can be adjusted in section B, number 6.
