Make volume louder (USB / DIY Modules)
On our sound modules, there no volume control on the module itself, or in the sound loader software. The only way to increase the volume is to amplify the sound file itself.
If your sound is too soft, you can use sound editing software to adjust
your sound file.
Many of our customers use “Audacity” which is free and can be downloaded at
http://audacity.sourceforge.net
You can also find resources on YouTube showing how to edit sound files.
