Thresh from MB2 controls MB1. Default max attack = 100 max is 50

Confirmed, also affects all build-in presets.

Looks like there is something wrong with the ITU Bass if you enable it on a band in the new Analog MB.

Multiple settings in Digital mode are broken. I've just compared against BETA016 (last version before I added Analog mode to the multiband compressor) and I see that Threshold, Knee and Band Mix values are all lost in the latest beta's.

Wow i love that sound. I am waiting for limiters and gates. Well done Hans and thank you very much (and please excuse me for my skepticism in the Telos post.) One wish though. If you put gates in the new MB (analog one) please put gate indicators in the MB meters.

Hi All,

I am running ST BETA 22 (standalone) on my test bench with FM TX unit via MPX.

CPU & Latency: Realtime, 4096, Quality 70%.

I have found that ST FM Output Buffers slowly drain away and overnight I have twice heard the buffer get down to low levels, resulting in strange audio sounds on-air. Eventually ST corrects the issue and restores the buffer.

The CPU Quality setting is at 70% and I would rather not reduce either that setting or the samples below 4096 as I am planning on putting the next stable release into a competitive FM market.

Rather than hearing 15 - 20 mins of songs that are affected by a lack of buffer, can we have a parameter which can be set to trigger a buffer reload / reset to overcome this ?

Also, I have had to revert my sound settings from 192KHz/24Bit back to 16Bit in order for the CPU (Dual Xeon Dual Core 5130 @ 2.0GHz) to keep up with buffering. I know there are some CPU changes yet to be made. Our production hardware is dual quad-core 2.66GHz so I am expecting that to work a lot better as it runs ST 7.60 now without any issues.

Any suggestions that could help with FM Output configuration are welcome

Thanks Hvs for a great product.

BETA 761-023

Windows 32 bit:
Windows stand alone: http://www.stereotool.com/download/ster ... 61-023.exe
Winamp DSP: http://www.stereotool.com/download/dsp_ ... 61-023.exe
VST 32bit: http://www.stereotool.com/download/vst_ ... 61-023.dll

CHANGES:
- Some settings from the 2nd MB overruled the 1st, causing all kinds of effects. That has been fixed now, and I verified that the audio of Digital mode in the 1st MB is (nearly) identical to that of BETA761-016 (nearly because in 016 the frequencies still were 10% off). New quickly put together preset (NICE2) attached.

Warning: ITU mode is broken in multicore mode.

OLD CHANGES:
Fix MB frequency band shift (10%, since 7.51 or 7.60) - Appears to be gone but I don't remember fixing it (!)
Fix RDS time issue! viewtopic.php?f=6&t=5941&p=28209#p28209
Added 2nd Multiband compressor! Example preset is attached below. To me, turning it off makes the sound boring/empty. I think this is exactly what some people were missing in Stereo Tool. And with 2 steps the audio is also more consistent than before. RMS/ITU based preset would probably be even better... To increase or decrease the effect, adjust the Density slider of the 2nd Multiband compressor!
- Optimized CPU load. CPU load now strongly depends on the settings, for the settings that I posted earlier it's now less than half that of Digital mode! On my system it went down (single core mode, CPU load on that core) from 12.3% to 2.5%! (Again, depending on settings). Digital uses 9.1%.
- Merged more parameters (Peak vs RMS setting) with old ("digital") compressor.
- Slower Release speed in Analog compared to Digital
- Removed Shape Enable settings.
- Fixed Knee in Analog mode
- Fixed Aggressiveness slider behavior for Analog (!), made it behave the same as Digital mode (acts only on release speeds).
- Merged more parameters (Attack Time, Release Time) with old ("digital") compressor. Adjusted numbers in Digital compressor to match the (correctly calculated) behavior in Analog mode.
- Merged parameters (threshold, knee, ratio, feedback, channel separation, band mix) with old ("digital") compressor, I noticed that I was switching back and forth all the time to copy settings, so this seems easier. Threshold is now also displayed in dB's.
Made Multiband version of the new compressor! Choose 'Analog' mode to switch to the new one. See attached preset for an example!
- Made new Traditional Peak mode which behaves more like normal Peak.
- Added Lookahead, removes huge spikes at start of attack for fast attack times and reduces IMD.
- Fixed Ratio behavior
- Fixed 'Density Drive' slider in Analog mode
- Fixed no audio with certain combinations of filters
- Fixed a filtering issue in the Digital compressor (!) when using Density Drive > 1.00
- Added lowpass filter to control signal to smooth out bad effects and remove distortion
- Added ITU-1770 mode to reduce pumping and improve level control
- Added Channel separation
- Rewrote all code
- Fixed Ratio
- Channels are not processed separately (wasn't the case before, and that was a bug)
- Fixed attenuation display
- Attack and Release times must be set to half the numbers of the previous beta's. Oil change speed must be doubled.
- Restored old Shape behavior from version 009
- Replaced 'Nonlinear Release' by 'Exponential Release', which works better and only needs 1 parameter. Use this to go up FASTER if you're down DEEPER.
- Added Ratio
- Added Feedback mode
- Fixed out-of-control behavior for certain extreme settings
- Fixed some more weird behavior things if the difference between Attack and Release is REALLY huge (behavior was bumpy and caused clicking sounds).
- Known issue: both Shape On settings must be enabled. I will probably remove them in the next build anyway so I'm not going to fix it.
Fixed a lot of bugs, will type the details here later. Oil Temperature is now in % and didn't work properly before. PLEASE LOAD THE DEFAULT SETTINGS for the new compressor or it will sound horrible.
Changed Attack Time, Release Time, Attack Speed Threshold, Release Speed Threshold to understandable values. Made 1.0 the 'standard' behavior for Shape.
- Added smoothing to oil temperature behavior for both attack and release.
Added Oil temperature behavior which was missing from my automatic (hydraulic) door model. Will explain below...
- Added another Peak mode slider in "New Singleband". The old one (from yesterday) works mainly on release, but in some cases the volume didn't go down fast enough on a loud sound. The new one works mainly on attack (higher value makes attack continue AFTER a peak.
- Changed Peak mode behavior in "New Singleband".
- New Singleband: Split Speed into Attack and Release Speed
- New Singleband: Made Attack and Release Speed Threshold relative to Speed - so you don't need to adjust it to change the shape.
- Added new Dequantizer filter to increase the bit depth of recordings.

TO DO COMPRESSOR:
- Fix MB ITU mode.
- Add Gate and Limiter
- Make Shape value small for high speeds
- Simplify interface (remove Oil Speed Adjustment sliders etc, move some things to Extreme Tweaker mode)
- Make SB compressors switchable as well, and support side chain.

TO DO:
Add RDS control via VST typedef VstIntPtr (VSTCALLBACK *AEffectDispatcherProc) (AEffect* effect, VstInt32 opcode, VstInt32 index, VstIntPtr value, void* ptr, float opt); for Bernd N
Clipper issues Leif / Wolf Stahl (probably the same thing)


Note: I made this preset in 5 minutes just to show what the new MB can do, it's not properly tuned!

If it's really the CPU load and it takes this long, then lowering Quality by 1% should be sufficient.

More likely, this could be a problem of a small sample rate difference between sound cards. So, are you using a different sound card for input and output?

Yup that's on my todo list!

Will do!

By the way, when you use both compressors, I don't really see a need for a limiter anymore... (but I'll add one anyway).
