I’m in Northern Ireland so its unlikey you are able to listen. If you need help/advice, I’ll help all I can. Also the other guys including the author will give you all the help they can. This forum is brilliant!!
What kind of broadcaster are you? ILR, Community or Pirate, don’t be ashamed to say, were all friends here.
No question will go unanswered.Yorkie.
[quote author=”Andrew”]Hi all,
A little off topic, but are there any guys in the UK that actively use BBP on an analogue FM transmission?
Thanks

Yes, me!

I was playing around with it, and this gave me a chuckle.
Check out the silent part of this Bryan Adams clip; it’s a rather amusing demonstration of Eruption. (Use headphones)
First in regular Plutonium:

Now in Eruption:

I’ve listened to them on headphones, at various different levels.
I notice very quickly exaggerated background noise and analogue tape hiss, apart from this, was there something else?[quote author=”TDCat”]
My personal preference is that the AGC should always be ‘a slow hand on the pot’ for processing with the multiband offering fast release times.
[/quote]Same here, something I mentioned some time ago and also asked if it’s possible to have seperate AGC and MBL speed controls.. Any chance of this Leif? This is still a major disadvantage of BBP against other products in my opinion.
Glad you got it sorted, unfortunately tho, the Patchmix DSP program does have to be running at all times otherwise the card is shut down too. The new driver does however make the card act like a normal windows sound device which is what we needed. I think it is possible to have some control from windows volume control but not much.
Leif, I know what you mean about drivers, this is also the case for most Creative cards, I have found most of the Audigys will only work in 192Khz mode with web drivers (and all the FX turned off)..
If you have just installed the drivers from the disk, the soundcard is difficult to use as a device in windows, like a conventional soundcard. Download the 2 latest files from the Creative website, theres the driver file: "EmuPMX_PCDrv_L6_2_00_11.exe and the controll app file: "EmuPMX_PCApp_L6_2_10_00.exe", install both of these and the card will then appear as a normal sound device in sound manager. This will make it possible to use in most apps, especially as an input device.
Hope this helps.
I would use a gating mic processor in the studio or a compressor with a gate into the insert of your mic channel. This will gate the noise at source and leave nothing for the processor to handle. Also you want to have the mic gain set to the lowest you can while still hearing the announcer loud and clear, again removing the noise at source so that the gate has less background noise to cope with. Maybe the Mic has a -10dB pad?
Thanks leif, This will help me very much although there will be a lot of experimenting to do in the meantime but now I will also use MPXtool to help with my measurements and I’ll really be able to see how much deviation i’m pushing and if there are any overshoots.
Just need to find a tuner with MPX output…I can’t help thinking this will not be easy.Warren.
Hi,
I’m nearly there I think… correct me if i’m wrong…
What i’m trying to achieve is to use ONE BBP at the main TX site to process the audio and for the audio from the L/R to be streamed to another site (this would be captured digitally and streamed out from the same box). The audio from the second site should sound (as close as possible), identical to the main site with perceivably the same level and also be within spec (no overshoots).
Main site takes care of itself.
Second site receives incoming processed audio (de-emphasised as this will also most likely be used as source for webstream). I wont be able to use High BR MP2 so let’s assume i’m using AAC+ 80Kbps with SR and all it’s inherent audio errors and overshoots.
I would NOT bypass the BBP running at the second site, I would select the "Protection Clip 6db" preset (which if I understand correctly does not add any processing to the audio but just passes it to the final clippers which will re-adjust for any overshoots added by the streaming process) and then adjust the final drive to get similar looking display on the output clippers as the main site (I will be able to monitor the main site from the second site). This audio would then just pass thru the BBP encoder in the normal way (RDS injected as usual) and to the second TX.
Is this what you would describe as the optimal way to achieve my goal?
In essence, this corrects for errors in the audio (overshoots etc) from the stream, gives me near-identical sounding audio and gives back the peak control lost over the stream.
Hopefully I’ve got this nailed now..
Many Thanks,
Warren.
Hi leif,
Thanks for your reply…
So tell me if i’m right here, if I stream the L/R out from the main BBP box, it should be "encoder ready" at the other end. Would this be suitable for any coder or would it still need to go thru another BBP (in bypass mode)?
I also gather from other threads that this audio will not be encoder ready if I use an encoder such as AAC+ or MP3pro as these employ spectral replication and as such will not properly re-create the tightness in the HF frequencies? If I use MP3 or WMA though, should this still arrive intact?BTW… Not planning to use any pre-processing, I want to let BBP do all the hard work for me. I was just wanting to use one BBP to do all the work at one site, then pass the processed audio to a second site with all the hard work done and put it thru BBP the other end but just the encoder part. From what you have said tho, I assume this effect can be gained by using bypass mode, thus the audio coming in, will not be touched by BBP again, just encoded and passed out to the transmitter, or if what I think you’re saying is right, it could go into any coder.
Oh, one other thing, I like to be able to control the AGC and multiband ride speeds seperately, is this possible in BBP as the speed control seems to affect both. Maybe I’m wrong here?
Many thanks,
Warren.
