Cyprus Radio Frequencies for cars imported from Japan

If you are having trouble with the radio of your car that was imported from Japan and you cannot tune in to your favorite radio stations you might have to do a little math!

On many cars that were imported from Japan it seems that to tune in to the station you like you need to subtract from the frequency 16Mhz. For example, if the station you are interested in is broadcasting at 97.2Mhz you will have to set your car radio to 81.2Mhz to listen to it.

A list of frequencies will follow soon.

A quick note on how to boost the audio stream in a video using the volume filter in ffmpeg

#;For newer versions of ffmpeg
ffmpeg -i input.mkv -filter:a "volume=4.0" output.mkv;
