Note that sounds 25–28 cannot be restored to factory defaults with the "YD:RESET" command. You will
need to re-upload original sounds again. Device firmware archive contains "SOUND" subfolder where
copies of original sounds audio files are present. The last two digits in file name are the factory start delay
and replay delay settings.
Device can accept audio files only in specific format — mono 16-bit PCM WAV files with sample rate of
22050 Hz, and length from 0.1 to 13 seconds (from 4 to 688 kBytes). Yes, the slot size is limited and you will
not able to upload your favourite MP3 track. But 13 seconds is enough for a long phrase.
We recommend free Audacity software to make audio files ( https://www.audacityteam.org/ works on
Windows, macOS and Linux). It allows clipping of files, adjusting the volume (Effect > Amplify...) and
saving in various formats. Make sure to set the "Project Rate" to 22050 Hz and save the file of type "WAV
Microsoft signed 16-but PCM".
