Stereo Tool

The BIMP is just microphone processing what i saw

In my openium total not needed, voice can be sound good whith your preset, when you use also voice processing together whith multiband processing its sounds "muffeled "like the dutch commercial stations

I just discovered that my code that protects against NANs probably doesn't work on older CPU's (it might even cause crashes by itself, I don't know). Older = Pentium 4 and the early Core2Duo's and possibly Core2Quads. What CPU do you have?

I was using a feature that those CPU's don't have.

It is a very good idea this project of microphone processing.
Some people want a light sound in antenna processing, that's why it is necessary to process a minimum the voice. And, taking the example of many commercial radio in my country in France, even with a heavy antenna processing, voices are still processed with a micro processor.

Hello Hans,

What is the action of the command: Secondary tightness speedup so that I can translate it properly

Can you please give more info on Bimp ?
When Bimp is used, do we need to turn off all in processing tab ?
How to register license to Bimp and how much ?
Regards
Stef

Hi Hans
I test on a Intel Core i7-5960X CPU @ 3.00Ghz (8 core/16 logical processors) 64bit Windows 10 Pro with 32Gb RAM.

CHANGES:

• Test MicroMPX with Stokkemask - 0.5 dB -> Changing setting in Stereo Tool helps
  
• Show a warning if Quality it not set to 150% for Latency 128 and 256.
  
• Bass Clipper sounds horrible at 128, True Bass at 128 and 256 -> disabled.
  
• Update Dutch Moose
  
• Clipper: Bass section lowpass freqs should not be too close at latency 512, 256, 128. (Noticeable in Dutch Moose preset)
  
• Check that The BIMP works, maybe add parametric eq
  
• MicroMPX rate limiter
  
• 192 kHz input is broken! Output is mono, something is going wrong
  
• SST ID's
  
  OLD CHANGES:
  
• Crackle in 2nd PDF track -> Improved
  
• Allow lower latency (6 ms, 9 ms)
  
• Improve clipper sound 1-6 kHz area
  
• License The BIMP
  
• Updated Paul Thompson's and Bojcha's presets
  
• Updated Dutch Moose preset (more highs. less deep bass, less stereo widening, sounds much cleaner)
  
• Stok: Lower samplerates look less good (and that makes no sense test without LOWER) -> 44.1 is ok now (-0.01 dB), 40 kHz is clearly lower (-0.20 dB), still way better than before (it was more than -0.40 dB in 9.02).
  
• Add MicroMPX plugin licensing [22]
  
• Fix Pi build (Stokkemask NEON code)
  
• Update LogInOut code
  
• New Stokkemask mode now works well in all Strictness settings above 7 (below 7 it's not very strict)
  
• Stok: Post filter caused NANs
  
• Stok: Move start point to later stage? (TUESDAY)
  
• Cleanup code for VST3 David
  
• Turn BIMP *OFF*
  
• DrawWave draws outside of screen in FM analyzer (TUESDAY) - apparently ok
  
• Include MicroMPX - for real now [22]
  
• Hide Matrix Stereo for now
  
• Stok: Add post filter
  
• Stok: Legacy CPU load back to that of 9.02
  
• API: Audio signal VU meter, info about whether stream is good NOW.
  
• Started with matrix-based stereo widener; not happy yet.
  
• Stokkemask NAN and other exceptions solved. (from previous beta)
  
• Stokkemask threading issue solved. (from previous beta)
  
• Stok: Remove overlap shortcut for stricter result (increases CPU).
  
• Stok: Measure mask in every stage for stricter result (increases CPU).
  
• Stok: Apply measured results in every stage for stricter result (increases CPU).
  
• Stok: Replace L-R reduction in final stages by total volume reduction.
  
• Stok: Figure out how to adjust shape at different sample rates -> Found correct Gaussian window sigma value instead, applied for both processing and display (which were set differently before!)
  
• Stok: Replace "Looseness (sounds better)" by something that moves the mask up and down.
  
• Stok: 1e stage only inner
  
• Stok: More steps at end, needs to be both tighter and have less effect (is that last thing still needed???)
  
• Stok: Try reducing the audio level in the final stage - lowering highs has proven useless at that point. --> SEEMS TO WORK, but only do this as the last stage!
  
• MicroMPX SWEEP
  
• Fixed a crash in the "Limit instead" code (Advanced Clipper).
  
• Removed (moved to Extreme Tweaker for possible future testing) some Stokkemask settings that had a bad effect on compliance. Good settings are 50% / 30% / 40 dB (without the 40 dB it should be fne too, but there's a bigger chance at overshoots at the bottom of the mask. 100% for the first value increases overshoots!!!!! 39 and 38 should be safe as well - but I haven't had time to measure those separately anymore. Anyway in the older versions this value was set to 0....... Setting it higher may cause an audio quality reduction.
  
• Crash fixed
  
• Stokkemask: Try I/Q Clipper mode, highs are coming out slightly too loud, due to LPF? Might be good enough... -> Idea doesn't work
  
• Stokkemask: We don't care about CPU load, try adding more stages -> No effect
  
• Stokkemask: Default back to 50% for safety - that way we don't have to worry about breaking older versions. And we still get 90% of the improvement that way.
  
• More experimental stokkemask settings added.
  
• Stokkemask: Improved further (looks about equally strict, but I can squeeze over 1 dB more anti-phase content through than with 9.02). NOTE: SETTINGS ARE DEFAULTING TO 9.02 BEHAVIOR BECAUSE I DON'T KNOW YET IF THE SIGNAL IS EQUALLY STRICT, AND I DON'T WANT SOMEONE TO GET FINED FOR HAVING STOKKEMASK OVERSHOOTS. To get the new behavior, set "New looseness 1" higher (50% should definitely be safe, I'm not sure about 100%), "New looseness 2" to 30%, and "Side level" to 40.
  
• Improved Stokkemask - output is stricter (closer to the mask), so it has less impact on stereo separation. (*)
  
• Memory usage reduced by about 12 MB
  
  PLANNED:
  
• Add MicroMPX decoder abonneer-IP Done but might not work - wait for Mathijs
  -
• Full height mode seems broken
  -
• Fri: SST/uMPX interface BUSY
• Freakday
• Video
  -
• MicroMPX: highs idea BUSY -> Find beta testers TEST STOKKEMASK EFFECT TOMORROW
  -
• Coins
• Add Kantar support BUSY
• The BIMP on LQLL
• Lower latency quality warning
• 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.
• Optimize Stokkemask post filter
• RDS urgent issue
• Cntrct IN
  -
• Show warning when using MME with wrong sample rate
• Test preset that causes buffer to run empty - why? --> Settings issue, maybe add a popup for this situation (buffer is slowly filling up or running empty)...
• 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 64 bit sound card exception handling in ProppFrexx - that wasn't the problem... apparently
  -
• 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: Support for AF method B
• RDS: RT end at \n
• Brian, NAB
• MOBO
• uMPX encoder/plugin: Sound card speed message
• uMPX decoder: Add multicast subscribe
• Add MagicRDS AF method B support

New vs old Stokkemask measurement numbers, relative to 48 kHz no stokkemask, for audio with quite extreme stereo. Numbers are L-R loudness, L loudness

Freq     old/new          L-R    L
48   kHz no  Stokkemask:  0.00,  0.00 (reference)
48   kHz new Stokkemask: -0.62, -0.27 (0.46, 0.10 better than old!)
44.1 kHz new Stokkemask: -0.63, -0.22 (0.54, 0.11 better than old!)
40   kHz new Stokkemask: -0.82, -0.29 (0.65, 0.14 better than old!)
48   kHz old Stokkemask: -1.08, -0.37
44.1 kHz old Stokkemask: -1.17, -0.33
40   kHz old Stokkemask: -1.47, -0.43

Much much better this one, just reloaded our own stereo settings in it. Shakatak, easier sad than done, first "say" was blown away by bass in the original settings (difficult this one also, we have a lot of tests like this just by ear) , that's corrected now rest is really very good Hans. Tnxs to this preset we're - finally - close to implementing the auto equalizer.

First, The BIMP isn't completely finished yet. Most importantly, we need to add something to turn it on or off (right now it's off if you don't use the SCA input, but that means that as soon as you enable SCA input for RDS, backup or SCA channels, it's also pushed into The BIMP).
The BIMP is indeed a microphone processor (BIMP standard for Built-In Microphone Processor). There were several reasons for us to put it in:

• We've noticed that several smaller stations don't have a microphone processor at all, and without aggressive processing on everything, the dj's sound pretty 'weak'. Beside that, you really want to have things like a noise gate on the microphone input - which really shouldn't affect music.
• Stations that do have a separate microphone processor and then run their audio through a normal processor have another problem: Latency. The BIMP is quite revolutionary, because: It adds NO latency at all. Nothing. 0. Not even 0.1 milliseconds. It talks to the other filters later in the chain, and gives them a (pretty accurate) prediction of what's going to come, so they (AGC, compressors, ...) can take it into account and prepare for it. So, when you use The BIMP and select the lowest possible latency setting, then the TOTAL latency of microphone input to your FM tuner output connected to a headhpone can be below 6 ms! You probably shouldn't put it this low, but at least now there's no need anymore to sacrifice music processing latency to be able to add microphone processing, or vice versa.

For now, The BIMP is a pretty basic microphone processor (for example it doesn't have a "boss" microphone mode which mutes the other microphone(s) if the host of the program is talking, and you can only have 2 microphone inputs) but stuff like that will probably be added in the near future.


To answer your questions:
1. No need to turn the rest of the processing off - it's designed to work together with the normal chain!
2. Registering isn't possible yet, because it's not finished yet.

Hans,

for the final version 9.03 can you update the French translation in your program please
