I ve got newwwwwwwwwwws 🙁
i just tested breakaway trial on 2 more FM radiostations broadcasting in my area with much much different configurations and very very expensive exciters and stl systems. ( Harris , ELENOS, SIEL )
no tilts. no interference.
ALL 2 stations ( and my station also ) have THE SAME LOW FREQUENCY EFFECT on the frequency stability ( mesured with 2nd IF status )
Leif, PLEASE PLEASE PLEASE, make an optional low frequencies filter for the mono signal only.
I AM 1000000000000000 % sure that this happens to any radiostations FM EXCITER who doesnt have DC block filter for the MPX
ONLY BREAKAWAY CAUSES THIS EXTREME frequent effect .
i tried also the presets "as is " without extra bass , and the same problem again, but less frequent , BUT it exists.
Stereotool didnt cause this becuse it uses a low frequency filter at the final stage before the mpx clipper .
ORBAN didnt cause this also with factory presets
OMNIA didnt caus this also with factory presets.i love breakaway’s sound , and i wanna use breakaway for my fm station . please!
100% clean.
!!!!
i compared with the original non-breakaway-processed songs and ..
i was amazed 🙂nice work!
😳Wow ! Very interesting presentation!
I think that 2010 was the year where " broadcast sound processors " became " sound artificial intelligence " .
something like a sound proccess robot 🙂
( latest versions of omnia, vorsis, breakaway, stereotool e.t.c. )
They are not just an…attack …release like the old old days.. 🙂
Things are changing,
not only attack release but… Psychoacoustic proccess 🙂)
Ok,
my " remotely controlled 170 kwatt room " runs this :PER.558268 INTEL CORE 2 QUAD CORE Q8300 2.5 GHZ LGA 129.58 1 129.58
PER.650478 THERMALTAKE CL-P0220 GOLDEN ORB 2 18.26 1 18.26
PER.553904 KINGSTON KVR1333D3N9/2G DDR3 2GB PC10666 47.71 1 47.71
PER.522663 ASUS P5Q-EM 113.00 1 113
PER.305109 INTEL X25-M SSDSA2MH080G2R5 2.5” SSD 80 195.98 1 195.98very very stable with esi juli sound output
( analogue…again..becuse FM digital direct synthesis …. is OFF )i have no problem broadcasting with this for MONTHS.
no audible problems, BUT my CPU …after 3 or 4 ot 5 days of reboot …goes to 50 or 60% ,windows 7 32 bit
windows 7 64 bit
clean installs with only microsoft security essentials loaded and ultra vnc .
latest breakaway ASIO version with high latecy enabled and no DSP plugins ,
nothing else.anyway, it’s not a problem for my quad core.
Jessie,
i made some more tests and yes , that happens to me only on high latecy mode ( in ASIO version using high latecy mode , tested 100 % now )
I have not tested the BBP versionI ALSO HAVE THIS …( but it’s not a problem for my quad core)
THIS HAPPENS ONLY WHEN USING THE LINEAR HIGH LATECY MODE .
After a reboot CPU is at 10, 12 % .
After one week or more CPU usage goes to 50 or 60% !Only when in high latecy mode ( i am not 100& sure)
Yeap! this tecnique reduced my " low frequency effect " in one of the 2 FM exciters i use for broadcasting.
BUT the competitive radiostations here use more bass than me without any problem ..using the SAME FM EXCITER using the same STL systems with another software processor and also orban 8400 with latest firmware,
( no tilt, no interference, )
anyway, it’s only 2 or 3 % of radio recievers that have that problem in auto search of a radiostation ( at the time that my MPX signal has that f@@cking 10 hz or 1 hz low frequencies inside )trouble ticket …closed 🙂
i wish LEIF makes an optional low frequency filter after the left right clipper with a " warning " for the small overshoots that may happen, , if a radiostation wants it enabled .
thank u everyone
i dont use extreme bass settings!!
nope, no dsp pluginsi ll record my MPX SIGNAL to a flac file on a few hours.
you will see it how it looks like[quote author=”sigmacom”]Please, let me explain from scratch what I call as "the very low frequency effect".
Will take some time, sorry for that:Imagine that you have an FM modulator at 100MHz, which deviates +/-75kHz when audio is +/-1V (2Vpp).
If you give 20 Hz 2Vpp square wave audio, a perfect linear modulator will force the carrier to be at 100,075kHz for 25mS and at 99,925kHz for another 25mS.
If you try to measure the output frequency, you will find it mostly at 100 MHz, but sometimes you may see a slightly drifted frequency.
This depends on how fast your frequency meter is. The faster the meter is -> larger drifting is shown.Now imagine a very low frequency (1Hz) square wave audio 2Vpp, which results in 500mS at 100,075kHz and another 500mS at 99,925kHz.
Any frequency meter instrument is obviously faster than that, and for sure you will see very large frequency drifting.
Remember, it is not an error, this is what your modulator is supposed to do with that kind of audio!At that time, if someone is auto-scanning the FM band with his radio, there is a chance for a very strict receiver to skip you, because at the time it tuned at 100,00 MHz, your carrier was at 100,075 MHz (or 99,925 MHz). It may stop at 100,05 MHz, or it may skip you at all – especially if your RF signal is poor.
We are talking for VERY implausible conditions! What are the odds for someone to have *that* kind of receiver, auto-scanning at *your* frequency at the *exact* time where you carrier isn’t exactly there for a long time?!!! WOW!
Well, it seems camclone has achieved all of them. His settings to produce tremendous amount of bass on air, produce constantly very strong low frequency components that cause his exciter to be for a long time away from it’s specified center frequency. This is readable with a frequency meter as "frequency drift", and he found some receivers that don’t stop at his station while scanning the band.With analog audio path, the series capacitors block or attenuate such LF components. Also, the PLL functionality will try to correct such errors, so the effect is minimal.
With digital audio path, there are no capacitors to help. With DDS there is no PLL to help. In this configuration, the "very low frequency effect" is fully revealed – unless you put an HPF at 2Hz.That’s why camclone is complaining about digital HPF at me (for DDS) and Leif (for BBP).
Even with the best audio card in the universe, as long as he creates that kind of audio and there is no HPF to stop it, the "very low frequency effect" will not go.P.S.
Sorry for the long post, I hope you understood exactly what’s happening.[/quote]even with default Breakaway Broadcast presets the …low frequency effect is present but less often.
i dont use any " alien spacy settings.. " ,
-50 shape + 50 level ?!?!?!!? mouhahahahaahaha!
are u kidding! ?
my basss is at +19 and the shape is at +14
( the low frequency effect happens to 1 / 20 of : auto search" cases to the 3 % of radio recievers. ( estimated )
a very small ammount of radio recievers models BUT FOR ME …. IT COUNTS!i want to be 100% compatible.
lol
check :
mms://1045fm.live24.gr/1045fm/this stream is with "dirty" treble becuse of the bad encoder ( simplecast wma sucks)
stop shooting me!!!!!!!!!!!!!!!! 🙄 🙄 🙄 🙄 🙄
that fu@@@cking ESI JULI soundcard.//.
good hardware but shitty drivers!!change the imput to 192 khz as output and it will work..
So , finnaly,
Leif is not going to put a second final high pass filter 1 level after the left right clipper ( with small overshoots) for those who want to be 100% sure that listeners who use auto-search of a radiostation tune in
🙁yeap!
it worked!
sorry for taking your time reading all this big story.
i wish leif makes a 2nd hpf before the final left right clipper.
or , finding another way for resolving this issue.
[quote author=”camclone”]I ve got news :!)
i made this test to be sure :
Radio automation PC —- > breakaway pipeline 1 ( or vac )—>
—–> mpx by breakaway ASIO or BBP (latest ver)—- > FM exciter ( elenos, rvr, sigmacom dds )
both 3 exciters have instabilities with their 2nd IF frequemcy, from 325 khz – + 2 khz up and down!!CHECK THIS OUT :
when i make this : ( tricky way for HPF 30 hz to the …output… with some small overshoots..?)
Radio automation PC —- > breakaway pipeline 1 ( or vac ) — >
—–> left-right output using brekaway Broadcast ( my 1st licence ) — > SPDIF outpput-SPDIF imput to Breakaway ASIO mpx output !! ( my 2nd licence ) the ASIO VERSION is BYPASSED MODE with 30 hz HPF — > fm exciters = Booooooooooooooooom!!! it works!!!!!!!!!!!!!!!!!!! no 2nd IF frequemcy roll !!!!
fm exciters went from – + 2 khz it went to normal + – 0.1 khz up and down!
( i made a 5 khz deviation …overshoots , but who caaaaaaaares?!?!!?!? now my station locks to all the radio recievers!in simple words : adding some 5 khz overshoots by using with my tricky way …the HPF 30 hz filter …also to the output of the left right signal ….i made my radiostation compatible with all fm car stereo recievers!
( i always play at 75 khz max deviation , before and after ) ,, ( rds and stereo signals to normal levels )so ?!
it works!but , …i use 2 breakaways. :! )
i proved that in my case this solved my problem but added 5, 6 khz more deviation…who cares?!?!?!
please add an 2nd optional 30 hz high pass filter at ONE STAGE BEFORE THE LEFT RIGHT CLIPPER so, it will controll better the signals below 30 hz..
( i think that omnia, orban, stereotool can do double HPF , 1 on imput and 1 at output before the clippers ( mpx , or left right )
i can send you my 3 fm exciters ! 🙂[/quote]
