View Full Version : BBC DAB stream bitrate mismatch?

Have you tried it using DABBAR? I use the 1.4 Dev10 release which
displays all the scrolling data and it works flawlessly on the current
SlimServer release.

Incidentally, what external antenna do you use with the Wavefinder?

Regards,

Stuart.

Cry for help..

I have a Psion wavefinder (with external aerial) + WinDAB streaming to
my squeezebox. This works very well for all but the National BBC
multiplex stream. After starting the stream it plays for about ~10mins
at which point the buffer empties and there is a pause whilst it
refills. It's almost like the BBC stream is being played too fast. Most
annoying as we spend most of our time listening to the BBC radio
channels!

This has occured on all 5.X releases. Platform is Win2K which is a
dedicated to the media streaming and serves multiple squeezeboxes.

Does anyone have any ideas? Thanks in advance.

I've just noticed that some of the items I record from radio using
Audio Hijack Pro seem to have a frequency of 22050. These play fine
through an analogue connection. I haven't bothered with going digital
even though I have a DAC, as the quality seems good enough for me.

But I might want to change at some future date. I seem to remember
that many DACs can't manage this frequency. Am I right in this
recollection.

The reason for the low frequency is that the programs I am recording
are just speech, BBC Radio 4 using Real Player, and I had set Audio
Hijack Pro to low quality MP3, which is stated as MP3 CBR stereo
64kbps. I'm not sure if the frequency gets foverned by AHP or by the
BBC stream.

Hey Daniel.

22KHz is quite usual for BBC Radio streams. In fact... AlienBBC forces a
resample step under some circumstances just to get around that piece of
behaviour. Thankfully mplayer can do it for us on the way out.

I'm in the process of trying AlienBBC on Mac OS X. I tried before but
at that time mplayer wouldn't download. I've now got it, and will
have some questions shortly.

If I wanted to use a DAC are there other methods apart from AlienBBC.
As I understand AlienBBC (but I could easily be wrong) it will let
you listen to BBC programs, but I am working with programs that I
have recorded to my hard disk for laterlistening.
