I haven't tested method B via UECP yet so that's very well possible.

But, what's wrong with normal AF method B?
Hans, I got too many duplicated frequencies in pira's RDS spy.
Will have to check it out once more.
Hm, I checked it with that. So.... can you show a screenshot or something like that? Thanks...
I will try to emulate Method B with Airomate and ST. Will post here in few days.

Stereo Tool 9.12 BETA004

Windows 32 bit:
Windows stand alone: https://www.stereotool.com/download/ste ... 12-004.exe
Winamp DSP: https://www.stereotool.com/download/dsp ... 12-004.exe
VST: http://www.stereotool.com/download/vst_ ... 12-004.dll

Windows 64 bit:
Windows stand alone: https://www.stereotool.com/download/ste ... 12-004.exe
VST: https://www.stereotool.com/download/vst ... 12-004.dll


CHANGES:
  • Volume display FM output seems wrong when streaming output is enabled with separate processing. Almost certainly only GUI issue.
  • Noise gate windows audible
  • Auto-select 192 kHz FM output sound card as default
  • No PIN EWS
  • Look at text alignment
  • Split RDS features in standard and advanced RDS (EON, AF method B, ECC, EWS, ODA - TMC etc)


    OLD CHANGES:
  • RDS AF method B
  • RDS AF method B via UECP Probably done but can't test it now.
  • White screen in generic plugin - was caused by wrong #ifdef
  • I/O and BIMP missing in web interface.


    TODO:
  • Nicer input sound card open error handling (softer beeps, retrying and restarting added).
  • RDS: Add PIN to interface
  • MicroMPX: Add manual (how to setup)
  • VST3 plugin BUSY
  • AAX plugin
  • Glitch when turning Bypass off
  • Linux MicroMPX version
  • Right-click tray icon bypass is bad
  • Dutch Moose schelle vrouwenstemmen
  • Linux-version MicroMPX integration in ST.
  • Pi 64 bit builds on the site
  • Support for more than 32 ASIO channels
  • Automate generating MicroMPX licenses
  • Automate generating The BIMP licenses
  • Backup audio doesn't go to LQLL
  • Finish Kantar tests and integration
  • Brian, NAB
  • VST for DJB
  • MicroMPX: highs idea BUSY -> Find beta testers TEST STOKKEMASK EFFECT TOMORROW
  • Test sound card
  • Linux multiple instances
  • Matrix stereo widener BUSY, problem with suddenly loud stereo (goes down in level, makes everything pump - badly). Try running L+R with a slower attack speed, if that doesn't sound good, remove it.
  • Fake stereo idea
  • Optimize Stokkemask post filter
  • Cntrct IN
  • Show warning when using MME with wrong sample rate
  • Add a popup for buffer overrun/underrun (also for suspicion)
  • Bug report: Linux version uses 100% CPU on one thread, even in bypass mode (must be sound card thread?) -> Not here. Not sure what's going on.....
  • Test ProppFrexx Windows 2012 server issue-
  • Declipper: Put startup in system tray back in Declipper (at least in the Winamp plugin version).
  • RDS: EON: Support for other type of AF frequencies?
  • RDS: RT end at \n
  • uMPX encoder/plugin: Sound card speed message
  • Add MagicRDS AF method B support
  • Noise in declipper issue

Hi hans,

it's possible in the next build to have the quick sweep (I/O - FM OUTPUT - TEST TONE)as in BAO, and relative PEQ?

There is a sweep that goes up and down. It's not exactly the same thing but it will quickly show you if there's any frequency issue.
What do you mean by relative PEQ?

thanks for the answer, yes, naturally I already tried with the sweep in ST, but being slow does not allow you to have instantaneously the frequency response from 20 to 60,000, while with the quick sweep see in real time the frequency response if it is flat (roll-off) or if it needs to be modified via a parametric eq (PEQ).

in this video, leif explains it much better than me.

P.s. SMSL Sanskrit it is an excellent alternative to the classic sound cards, naturally in some particular uses, eg. VAC input (100 euro)

I forgot, PEQ, parametric eq

Ah, there IS something like this in Stereo Tool but I made it many years ago and it's not a parametric eq. But, it can be used to make even completely nonlinear transmitters flat (I tried with a $15 battery powered transmitter). You can find it under the FM sound card settings in a subpage below that. But, there's no way to get it perfect with only a sweep, you basically need to play each frequency separately and measure and tweak not only the amplitude, but also the phase. (Having said that, you shouldn't need it if you have a somewhat decent sound card and transmitter - tilt correction + high frrequency correction is normally sufficient).

But.. peq is better and quick sweep is easier to see.

sure hans, tilt and calibration were the first things I did.
I agree with bojcha.
