Wait, are you telling me that a good DRM-signal in 10 Khz sounds (e.g.
in stereo) sounds worse then the same signal in AM?
Yeah, I'm telling you that DRM in 10 KHz the sound quality sucks.
Do you have audio-samples to support this claim?
Yes, on the DRM web site. They have example of strong and weak signal
DRM reception and compare it to analog. I've written this for the third
and last time. Here is another thing I'm writing for the last time and
that's low bit rate audio sound sucks whether the source is a DRM
broadcast, streamed from the Internet or a recording.
I listened to the samples on the sites and all of the "High Quality" DRM
samples sounded better to my ears than the corresponding analog signal.
The "Robust Quality" sample had a lot of digitizing artifacts, but that
used a very low bit rate. However, it may be preferable to the analog
equivalent. That would be a personal judgement, some will prefer the
analog, some the digital.
From what I hear in the samples, any of the 64 QAM/"High Quality"
signals is better than the analog equivalent. To me, DRM has good potential.
