Way to measure bitrate transmitted.

[bossmsx]

One of the nifty things my Perstel DR101 had when I got it in Toronto was that it told you the bitrate the station was running, among other things...CHUM's DAB component ran 192kbps, Mix 99.9's ran 224, CFTR was at 128, etc...Of course, we're talking about a different format (Eureka-147), but does anyone know if there is any way to measure bitrate, either by a radio that exists that shows this on the display up front, or any setting on the Boston Recepter (or actually taking audio of an HD station and putting it through some editing program on a PC)?

That would be interesting knowing on ANY STATION (Analog also)

Lately i have noticed that WJR has sounded VERY GOOD @ NIGHT (They must have the BITRATE way up on the analog side)

Listening to Dr. laura i find i have to TURN THE BASS DOWN on my radio its so good ;D (Listening in za car)

The Sangean HDT-1X shows data rate.

Hey DUDE:
WJR is only running analog RF at night, no digital HD-AM at night.

The Sangean HDT-1X shows data rate.

I cannot seem to find this option on mine. Perhaps my firmware is too old?

Bit Error Rate is not Bitrate

Bit Error Rate is not Bitrate

Sorry for misunderstanding your question. There's a max of 96 K bit rate for FM and 32 Kbps for AM. The best you'll get on any FM today is 96 Kbps. I don't believe there's any indication on current radios as to what bit rate a specific channel is being transmitted at.

Try listening with your ears! Bitrate is NOT a reliable indicator of sound quality anyway, particularly when comparing one system (Eureka) with another (HD Radio). The Eureka system used in Canada is older than the American system, and uses MPEG-2 as the codec...which requires a much higher bitrate to equal the sound quality at lower bitrates on newer, more efficient codecs such as aac+, and it's "kissin' cousin" the HDC codec used on HD Radio. 96kbps with HDC is certainly as transparent as 192 or higher on older codecs. And 48kbps sounds better to many than older codecs at 128kbps. So relax, and LISTEN. HD radio isn't an mp3 file. You can't expect the rates at which you get good sound on, say your mp3 player (or Eureka radio) to bear any relationship to bitrates on HD radio's HDC codec.

So again, LISTEN WITH YOUR EARS. They're NOT laboratory instruments, are far from linear, and don't hear the same way measurement instruments do anyway...which is why lossy codecs work in the first place. It sounds good. It doesn't sound good. That's all listeners really need to know.

(Seek out some internet radio streamed in aac+...even 32kbps stereo stations sound quite passable, 48kbps is damn good, and 64kbps or higher are good enough that most people would be satisfied even for critical listening. These bitrates would have sounded awful a decade ago, with the codecs we used then. Bobby was right, the "Times, they are a changin'"

Oh ok,no wonder they have the bitrate higher then (I thought it was disabled)

Well, you're right about that! Maybe Sangean needs to change their website. It clearly says the radio will display "data rate."
