I'm having a problem with one of my feeds that I can't find a fix for (other than switching to linux).
The feed source is TX audio into the repeater > Windows 7 machine > Radio Feed (also tried Scannercast).
The audio input to my soundcard is at a proper level, and the "slider" on the soundcard line in is set at a point where maximum deviation on the receiver just almost redlines the sound card input.
But,
When Scannercast or Radio Feed encodes the mp3 bitstream, the encoded level is at least -10db in level, making the sound way too low compared to other feeds - especially my other feed. I can't raise the input level of my line in without clipping the A/D. My other feed is provided by a Raspberry Pi using Darkice and LAME, which allows me to tweak the parameters of LAME to optimize the bitstream in various ways. The Raspberry PI feed is at the proper level and sounds great. However, the feed I'm having trouble with (Windows 7/Radio Feed) does not seem to have provisions for optimizing the mp3 stream.
Can anybody help me with this low audio problem, or am I going to have to buy another Raspberry PI?
I know there has to be lots of working examples of Windows / Radio Feed that have the proper level, so what is wrong in this particular case?
Thanks,
Justin
