I’m struggling to get my FM broadcast to match the volume of local FM stations. My sound quality is great minus the volume being somewhat low. I’d like to prevent people from getting blasted when they switch back to a regular station. Am I wasting my time - trying to achieve something that’s not feasible? I’ve read that FM broadcasters use dynamic compression to allow loudness. I’ve played with that on my audio files in Audacity with limited success - still never achieving the volume I'm looking for.
Here’s my hardware setup:
Pi 3 B v1.2
FPP v5.2
Soundblaster Play! 3
Signstek ST-05B set to L
Homemade dipole antenna
I’ve followed the Jason Rasmussen videos on optimizing sound. FPP volume is set to 70. My Signstek volume is set to about 11 o’clock +/-.
As I mentioned, my sound quality is great at these levels. If I push the FPP volume or the Signstek volume, I get bits of distortion on certain songs. I’ve been using The Beach Boys - Little Saint Nick as a test. At about the 9-10 second mark, the words “this time”, the “s”, “t” sounds distort if I push the volume higher than my current setup.
I’ve tried the following:
- turning up the Signstek volume
- turning up FPP volume
- stock Signstek antenna vs. mine
- removing the SoundBlaster and using the Pi’s built in sound
- setting the Signstek to H power (I knew that would have no impact but tried it anyway).
Any thoughts? I’m struggling to remember if other shows in my area had similar volume to mine…
Thanks.
