Are there plans to improve FM calibration? I have a transmitter with a hilly frequency response. My idea is an EQ where the curves for amplitude and phase could be drawn.
So it's even more extreme than what the current calibration offers???????? I originally made this when I had a 15 euro test transmitter, and I could make that flat with this calibration. I've used it once on a real station that had a very broken STL, but I've never seen any station that needed more than the standard RC correction since then.

In the audio input section I'd like to see options for speakers to be included without having the need to use virtual cables to route. I was thinking something similar to Rocket Broadcaster. There's input for mic and separate application source.
I have always thought that that was a Windows/sound card feature (some sound cards allow you to record the output that's sent to it). But I thought that that would just be offered as an extra input in the sound card list. If RocketBroadcaster can do it, there must be something else... I've put it on our todo list to look into it; if you happen to know more let us know.

Hello!
I have a valid license FM Professional+ Declipper whose license does not work as a plugin in vmix. As a standalone application, the license works ok without problems. When I install the plugin in vmix it says: vst plugin use whitout license.
What would be the problem, why doesn't it work?
Have you tried (re)entering the license in the plugin from within VMIX? The standalone registration doesn't register the plugin version.
I think that I have just fixed this, will be in the next beta (10.11 BETA011). I'm not 100% sure.

I found something
AGC(current) bands: Sliders shows (for example 30Hz first band), but graph shows way to high slope point, that starts to "fall" at 200Hz. Is it right, or something is wrong? I thought, it`s suppose to be the "point of slope starting" - i.e. 30Hz.
Why is this "offset", if i can call it that way?

Another example is : (if 4 bands is selected), last band slider is at 24000 Hz, but high slope starts at around 11000 Hz.
The frequencies are not crossover frequencies, but the center of each band. This is a thing on our todo list; we want to switch to crossovers, but that's not as simple as it seems (I spent a day or 2 on it some time ago and then gave up, for the time being).

Well, according to the thread I created, it seems I am not the only one who has a terrible FM Transmitter with tilt that cannot be fixed with current implementation. 2 companies selling similar overshoots. One of them with TERRIBLE support (which I had), one with better (but not always the greatest according to @Anthony96922).

Does that count as being scammed?

I'm not sure that I hear what you're describing. The other (HD) recording sounds more squeaky to me. Can you give me the exact time stamp in the ST recording where you hear it, to make sure I'm listening for the same thing that you are?
Fair... HD isn't a great example... since it already sounds squeaky. I got used to the high-pitched stereo squeakness. here is FM: https://youtu.be/T-5-SonLY3M

On Stereotool, it doesn't sound spacious & it sounds limited in stereo. It's like I put a hard brick in it. Is that a better explanation? It's like bland. I said it sounded squeaky because nothing sounds strong?

it is the same way throughout the whole song in my opinion
Ah! Now it makes more sense. Yes, I heard that too - I guess the compressor is configured to act very slowly. The HD signal especially sounds like heavy, fast moving compression is going on. Also, if you used the AGC in matrix mode before for stereo widening, that's now gone because the AGC is gone. So we do need a new stereo widener. And potentially a 2nd fast-acting compressor stage to add more density to _all_ material.
Yeah! I chose HD because the HD signal sounds heavy the most. I think it should be backward due to the codec...
Is Matrix mode not something you planning on adding to the new AGC?

Hi, for me the message after activating the web server still appears after starting the ST, I didn't find the option to disable the message, another thing I found interesting was when umpx sets it to 400 kbit/s the average bitrate shows 325 kbit/s.

I have just fixed the message; will be solved in the next beta. The average MicroMPX usage can be lower than what you set if the signal is very easy to encode (at some point there's nothing left to be encoded). For example pure tones, silence and mono audio can cause this, up to a point.

Well, if I can make my 15 euro transmitter that was just intended to send audio from an MP3 player to a car radio flat with the available settings, I would say yes.

Yes, but the whole idea is that you don't need an AGC anymore if you use the new compressor.

Hello,

If I start the 10.10 shared library Stereo Tool with Liquidsoap, liquidsoap stops with the following error message:
Code:
At streamtranscoder.liq, line 12, char 2-68:
s=track.audio.stereotool(%argsof(track.audio.stereotool[!id]),audio)let replaces s=source(id=id,{audio=(s:pcm),metadata=metadata,track_marks=track_marks})s

Error 14: Uncaught runtime error:
type: invalid,
message: "Invalid stereotool library",
stack: at streamtranscoder.liq, line 12, char 2-68,
at streamtranscoder.liq, line 12, char 2-68,
at streamtranscoder.liq, line 35, char 2-202
There is no such problem with the previous version.
The old one has libStereoTool_64.so, the new one has libStereoTool_intel64.so. I renamed this accordingly.

Will it be possible to upload a shared library beta with the next beta version?
Hi SysERR,

Can you help me to reproduce this issue? I have no experience with LiquidSoap and it doesn't look like I can just install it and click a few things...

To my knowledge we haven't changed anything inside this plugin since the beta's that did work, so this issue is pretty strange. I assume that you're testing with a 64 bit Intel/AMD Linux machine? I saw one other similar message recently, but that turned out to be a problem with the version of LiquidSoap, rarther than Stereo Tool (see the bottom of https://github.com/savonet/liquidsoap/d ... nt-6015827 ). So just to make sure: Did the previous (beta) version work in the same LiquidSoap installation?

I've used it once on a real station that had a very broken STL, but I've never seen any station that needed more than the standard RC correction since then.
After some more calibration with MPXTool I managed to get the transmitter to work a lot better than before. Other than the occasional 1-10Hz "wobble" the signal seen on MPXTool is nearly spot on. (I had the Composite Clipper enabled during adjustments and testing.)

I think a 10Hz band could be added to the calibration filter to eliminate the wobble completely.

I've been discussing this issue with Paul of Aareff for a while now to see if it can be even better.
