I have a new phone that was supposed to be identical to the phone I had a couple of years ago. It isn’t. One difference: on my old phone, all I had to do was record from YouTube or similar sites, and could automatically use those tunes for ringtones.
This phone says QCP format not supported.
Not even knowing what that means, I read on a Wiki site that it could be converted with the Audacity .exe installer. Downloaded & installed it, but I have no idea what to do after that.
If you can transfer the file to your computer using the USB cable, then if you install FFmpeg, Audacity will be able to import the QCP file assuming it contains QCELP or EVRC format. Assuming your phone supports WAV, export from Audacity as WAV.
If you need to convert to MP3, install LAME which lets Audacity export as MP3.
