How to convert m4a to m4r on Windows 10?

Before you start converting M4A to M4R on Windows 10, there are a few things you need to know： 

1. First off, remember that M4R files are meant for ringtones, so they can’t be longer than 40 seconds. If you throw a full song in there without trimming it, you’re gonna run into problems. So, make sure to chop down that track before you convert M4A to M4R!
2. Don't just grab any random converter off the internet. Some programs are sketchy or full of ads. Stick with well-known options like iTunes (yep, it’s still useful!) or dedicated converters. They’ll save you the headaches down the line.
3. Make sure you pick the right settings. M4R is just a renamed M4A file, but some converters might try to give you something funky. Double-check that you’re actually set to output M4R.
4. After you convert M4A to M4R on Windows 10, give your new ringtone a quick listen. Sometimes the volume can be wonky, and you want to make sure you won’t miss calls because your ringtone is too quiet.
5. If you’re planning to send it to your iPhone, make sure you know how to sync it correctly with iTunes. It can be frustrating if you think you’ve done everything right but can’t find your ringtone on your phone.

In short, keep your tracks short, use trusted software, confirm your format, mind your metadata, check the volume, and sync like a pro. Avoid these pitfalls and you’ll be jamming with your custom ringtone in no time!
