Save the edited file: Once you're satisfied with the edited ringtone, save it as an MP3 file. Most audio editing tools or ringtone maker apps provide an option to export or save the edited file in the desired format.
Transfer the ringtone to your phone: Connect your phone to your computer using a USB cable or use wireless transfer methods like Bluetooth or cloud storage. Copy the MP3 ringtone file from your computer to a specific folder on your phone where ringtones are stored (e.g., the "Ringtones" folder).
Set the ringtone: On your phone, go to the Sound settings or Ringtone settings. You should find the newly added MP3 ringtone in the list of available ringtones. Select it as your default ringtone or assign it to specific contacts, depending on your phone's settings.
Note: The specific steps may vary depending on the operating system and device you're using. If you're unsure about any step, consult your phone's user manual or search online for device-specific instructions.
