New user here, with Win 10 system and Audacity 2.4.2. I reduced the volume of the song, exported it out of Audacity, then uploaded to phone system on cloud, and it is still deafening. How to same song at reduced level of volume? Thanks.
I reduced the volume of the song,
How did you do that? How much did you reduce it?
Use the Amplify effect and try Amplification of -10dB (or maybe -20dB for a more extreme effect). Technically, if you enter a negative number it’s actually attenuating, not amplifying.
then uploaded to phone system on cloud
I don’t know what that means but whatever phone system you’re using might be automatically re-adjusting the volume. For example, all of the popular streaming services do that so if you upload something to YouTube they try to match the volume to everything else.
