Placed onµSD card and files
As you may have noticed, all songs have a number as name. This is done so that you can easily change numbers. Unfortunately, you can't just put a number on your SD card. You must first put them in 8bit, in 16000 Hz and in mono. You can easily do this via this site: https://audio.online-convert.com/convert-to-wav with the advanced options you also have to set the PCM format to 8 bit
