Hi guys & gals... <rant mode> I've been toiling a bit at the radio station for the last couple weeks limping along with our Classical station audio after our 20+ year old Orban audio processor puked one day. I first tried to get buy with nothing, but just couldn't balance maintaining the maximum deviation limit (105%) and the noise floor. The sound was either clipped or you just couldn't hear it on the air during the quiet sections. Next up was to use the same Orban PC1100 PCI card I use for our Classical webstream. I got things dialed in OK, but it's still half-assed. Clean, but still needs more compression to get over the very low power we are allowed, so I'm not getting much boost from the processor. So, I recommended a new FM processor which is ordered. So, while I was lamenting why it's so damn difficult to compete on the dial with the big commercial FMs - telling the GM how/why these guys sound so LOUD and why that would destroy the Classical format if we copied them - I got an idea for an experiment that I conducted earlier tonight. I took the output of my tuner (a Boston Acoustics Receptor HD unit) and piped the input into my ProTools rig at home. I recorded 60 seconds of music on 20 FM stations on the dial - without adjusting any levels on the record side. Wowsers! The waveform views confirm what my ears have been telling me, but far worse. Nearly every one of the waveforms (except my three signals - NPR Talk, Classical, and a satellite Jazz service) are SQUARE WAVES. Crammed up against the limiter the entire time and running peak FM deviation., be it rock, oldies, christian, country, or urban formats. I have to do a bit of analysis, but I can pretty well guarantee that at least two stations are greatly exceeding the FCC maximum deviation. (I'm debating about borrowing a HP modulation analyzer from work to confirm this.) So, all you Mastering and Mix Engineers are just having your work ameliorated by this overcooked processing. Imagine seeing a waveform from a 60's tune coming out like a square wave. It doesn't matter what you do before it hits the air - you have ZERO control over how it sounds when it airs. ZERO. </rant mode> So, what I really want to know is - what do you guys want to see from this experiment? The waveforms? Spectragrams? RMS levels? It may take me a few days to get some graphics of this, but give me some ideas and I'll try to show you reality.
