Your Q8 has a MicroSD memory card reader. If your personal computer can also read that card type (Most laptops are so-equipped), you should be able to save a music file
The Q8 is a smartphone. Most smartphones will let you save any song found online by tapping and holding your finger on it, then selecting 'save.' Once a music file is saved to your media library, tap-and-hold it and select 'assign' from the drop-down menu.
The LG Q8 is an Android phone and there are plenty of free ringtone apps such as MP3 Cutter, RingDroid (open source) and more.
The Q8 is compatible with the 'USB Mass Storage' norm. Get a USB cable (There might be one in your LG Q8 package) and, linking your LG Q8 to your computer should make it appear as a memory key. Open it and just drag songs or other sound files straight to your phone, as if it was a folder in your computer. For the remaining steps, please refer to your LG Q8 manual. The ringtone section should explain how to assign an uploaded file as a ringtone.
