I think it doesn’t require a lot of work and it is very useful that the stream receiver contains a log with an overview of interruptions (with time and date). A little more complicated, but it is also not impossible to add auto e-mail sending option in the case of a problem with the stream, or other error (in/out, MPX overload, hig CPU ect.)
@MrKlorox no, I didn’t bring stereotool into the discussion. As the author of this topic announced either the purchase of hardware or the transition to “louder software”, I was convinced that we had finished further discussion, but apparently we have not.
@in2beats, I would recommend you to install, if you haven’t already, other demo applications for this purpose, and then check for possible phase deviation.There are at least three applications on the internet that can be downloaded and tried. That way you will be 100% sure that the cause is not hardwareAs i said, i haven’t noticed anything like that in the Breakaway one operation so far, and i also use a set of professional modulation measurement tools including a Pira analyzer. The only thing i removed from the chain in practice is the behringer card (HD series 202,204,404) that Leif uses in the demonstration video. Each of them has nasty interference above 40KHz, which primarily affects the RDS carrier.
I still claim that this is software for enthusiasts, which does not mean that it is not suitable for professional use. It just means that you need to sit down and spend a certain number of hours to get it right. And that’s acceptable in my opinion considering the price and what it offers.
Ask yourself how many stations have a qualified person who will do this job or who is ready to spend hours tuning the application in addition to their regular work.
That’s why, as a rule, in broadcast systems, you order hardware from a renowned manufacturer and possibly a custom preset, screw in the BNC and power supply, adjust the mpx level, and there’s no more need to poke around and worry if Windows or some of the PC hardware will scream. But of course it costs money.Just to add to this topic – in the broadcast chain, at this point, the regulator does not distinguish between software for licensed stations and software for hobbyists. It is important to him that you do not go over 75k, and in certain countries that you comply with ITU sm1268, and how you will do that is your concern.
Just a little more about the pilot. If the equipment has a good linear characteristic (no phase distortion/amplitude deviation within the baseband), there is no question of going over 75KHz with a nominal pilot value of 9%. If there are overshoots then the problem lies in the sound card, STL or TX, which can be partially corrected within the BAO software.
And yes, the pilot can be regulated without Leif’s intervention, you just need to think a little about how to do this inside the software.At the end, if your phase correlation with other applications is good, I don’t think that you will find solutions by writing here. Only direct correspondence with Leaf remains, no matter how slow it may be.
I can already see the 2nd chapter of the frustration on the stereo tool forum – Mr. van Zutphen, the phase is killing me, your product is crap, I will buy the Omnia 9 in the future :D.
Now seriously. As far as I understand, it worked ok on the old hardware, but it doesn’t work on the new one? Why don’t you first suspect that something is wrong with hardware?
About “bad” support, i see BAO as software for enthusiasts who don’t have money for expensive boxes. The author explained the basic setup with which the software becomes operational, and the rest is up to you. If you are in serious business, then you buy a piece of hardware that costs xxxx euro and you get xxxx pages of user instructions and online support.Speaking of the 13year old Breakaway broadcast soft, with decent sound card, it only required a test of phase distortion, amplitude response and emphasis setup. Later, you choose a preset according to your own taste, do the final touch in very modest settings and go on the air. I don’t know how you could spend hours on that?

Warning to anyone who thinks to use behringer umc hd card for MPX. For some reason (probably poor power filtering) the card has nasty interference from 57KHz up to 100KHz. It is similar with scarlett 3gen!I didn’t understand the issue with passtrough, but explanation about how to use it is on youtube
The process goes:
1.Pass-through (original unprocessed material)
2.encoding (FLAC if you have enough bandwidth)
3.ip transport
4.BAONE streamreciever (on RX site)
5. Processing BAO (RX site)
6. ON AIRI use BAO primarily to generate MPX, so I don’t have much experience with stream encoder capabilities. The MP3 codec that is an integral part of BAO sounds good, and related to PCM you have the option of using FLAC. It’s not the same as PCM but it sounds just as good!
Related to AAC + I used an external application intended for the stream (I will not advertise it but it is very popular). The internal aac + (came with app) at 64kbps as well as the aac at 128kpbs sounded worse than the BAO with enc_aacplus.exe.
I note once again that aac + at 128Kbps doesn’t make sense because given the limitations it sounds just as good / bad as at 64kbps. Regular AAC on BAO (instaled from the same package as enc_aacplus.exe) at 128Kbps sounds decent. Maybe there are better encoders but I haven’t had a chance to try them out.
In the future, I place my hopes in xHE-AAC. I’ve listened to samples at very low bitrates, and the results are promising.greeting!
Tilt is well explained in the instructions for the old BA broadcast soft. In short you need to be able to view the demodulated MPX on an oscilloscope to adjust this well. It is ideal to see a square on an oscilloscope. But due to the nonlinearity of the sound card and the transmitter modulator, this is often not the case. So the correction is done via Tilt Compensation until a square is indicated on the oscilloscope. Why does this matter? Because it affects the occurrence of overshoots in the modulation process. If you do not have adequate equipment, there is a possibility of improvisation. You turn on the square generator while looking at the deviation meter of the transmitter. You make a correction until you get the lowest deviation value. For a similar reason, eq correction is done. But for her, owning a spectrum analyzer or oscilloscope is mandatory.
this also applies to Processor-> Misc-> I/O ->MPX and Processor-> and Misc-> I/O -> L/R Output (next is stereo encoder..)
Processor-> Misc-> I/O -> L/R Output – “Sub Level”: injection l-r (more less l/R difference on final out)
Since the official version does not provide deeper tweaking on the settings of the agc, multiband and final clipper section, anyone with basic knowledge in the field of FM production should have no problems with setup. This application is not even intended for those who are new to the term broadcast processing. The installation instructions and the first setup were explained very well by the author through youtube clips.
Leif once stated that the application was made with the intention of not tweaking much on it, and to get a decent sound.
As there is no possibility to legally access attack / relase, ratio, band mix and similar settings, then there is nothing to explain. And if you want to have all the settings available then you buy the hardware, and with it you get the manual! Of course it costs 10x.Enter a term in the old forum “Audio_Encoder_Codecs_setup”. By installing you get aac +, aac, ogg, opus. Remember aac + (He-AAC) is only effective up to 64kbps. The sound quality at a higher bitrate will be equal to encoding at 64kbps. Personally, I think HE-AAC can satisfy listeners only on cheap multimedia devices. To get the basic HiFi experience the minimum is 192Kbps and a decent AAC encoder.
most likely pll loop filter problem. more or less can be fixed using the Corrective PEQ option in BAO. Example for start: gain -2 at 20Hz width: .5 Oct. Be sure to use Phase linear options!
Now turn on the sine test and the frequency at 20Hz. Adjust the Eq gain until you get 75K. After that 30Hz. If greater than 75K, increase the Width option until you see a change to 30Hz. Now 40, 50 …. 100Hz everything must be at 75K.
“I set the deviation to 75kHz with the Bessel Null calibration at 31187.6Hz”
bessel null is used to calibrate an MPX tool, transmitter deviation indicator or other monitor mode, not to set BAO.For this you need a spectrum analyzer or network analyzer (you have to visualize the RF carrier).
To set the BAO (if an MPX tool or other tool is calibrated) you first test the square response. Then you select 400Hz and adjust the MPX level until you read 75K on the MPX tool. If the transmitter’s amplitude and phase response is good (the same goes for the card) then it should not exceed 75K.
if BAO HD output produce stereo for streaming, as he said, then the input should be ok. Of course, assuming that the identical input for hd and mpx at bao setup is selected.
it is not so complicated..
1.BAONE go to -“Misc”- “MPX Output” 1or2 -“test generator” (set to Qsweep)
2.Soundcard output of PC1 connect to “line in” on 2nd PC
-Make sure that PC2 has 192KHz soundcard and it is set to 192KHz samplingrate (recording and playback). Otherwise the test makes no sense!
3.Install adobe audition on pc2
4.Start recording (new waveform set to 192000)
5.Press alt and Z for frequency analyzer
That is it!
galileo figarooo;) there may be a number of other reasons for mono but without a spectrum analyzer it all comes down to speculation. first, the simplest, try listening on another radio. If it is on the other “mamma mia” on both channels, there is a suspicion of a realteck chip that cannot push a flat response up to 57KHz or is up to a transmitter with a similar problem.
What you can try is the following: on another computer that has a 192khz sound card (assuming it’s ok), install cooledit / audition. On line in connect the BAO signal from the first computer. Enable quick sweep in BAO settings. On cooledit choose 192KHz recording. During recording, choose spectral analysis.
If everything is OK you should see an almost straight line up to 57KHz. If you see more attenuation on any part of the spectrum, a sound card is not ok for this purpose.
