Hi Michi!
The files started out as .wav, and then I encoded as .mp3, yielding filename.wav.mp3. If you look in Explorer, which hides extensions by default (BROKEN!), it will say Filename.wav. This is an age-old problem, and I cannot take responsibility — Microsoft has pulled this crap since Windows 95. If I had removed the .wav filename ending (before the extension), it would have shown up in explorer as no extension at all.
I used Breakaway Broadcast Processor. So, the files were processed for FM, at 75us (north america / asia). Bandwidth is limited to 16.0 kHz for pilot protection. This is absolutely applied out of the box — in fact there is no way to turn it off in BBP. Noise reduction was on — this is switchable.
If you say there is lost definition, I can’t argue — there’s always compromises to be made when processing aggressively, but I wonder, what processor are you comparing to? Or, are you comparing to the original? Because, the original cannot be put on the airwaves unless you make it exceptionally quiet. If you want it the output of BBP to sound more like the original, I recommend Reference Settings, and feel free to turn Final Drive down a bit!
In fact, for the most transparent sound of all, you could even use the Bypass button, because pre-emphasis, low-pass filtering and distortion-cancelled clipping are still active even in bypass. The reason for this is that de-emphasis is always on in receivers, thus pre-emphasis must be on at the transmitter, and the maximum +/- 75 kHz peak deviation is not a recommendation. So, bypass is basically the same as the Protection Clip preset except you get no final drive control in bypass. 🙂
