white noise

Hi mo267,

The problem occuour when the source files are 32bit format.
Somehow you need to change from 32bit to 24 or 16bit before you create new MultiTrack song in uTool.
There’s a free audio editor application: https://audacityteam.org/
With this application you need to open your 32 bit wav files(s) then click on the File/Export tab and select wav (16 or 24bit) for output format from the drop down menu.
Use this file(s) to create new multitrack song in the uTool, then re-export your song(s) from the uTool to your USB storage.
