Hi OP friends
I have produced a number of simple audible warning messages (sample attached) to be played via an OP over temperature action.
The problem is that there seems to be a lot of background noise in the Pi audio output.
I have tried both HDMI and analogue outputs as well as a USB audio dongle but all give the same background noise.
Ive also eliminated PSU noise by running on a 12v battery.
Anyone got any tips for cleaning up the audio output ?
Thanks
Steve
