CHANGED:
- Exciter: Improve start of filter (less steep!)
- Fix crash in BETA036.
OLD CHANGES:
- Bug in 034 should be fixed again.
- Exciter: Make it possible to choose where in the chain to run it
- Hide Stereo Tool name and THIMEO in help window in specific versions.
- VST plugin level should be ok again
- Did some optimizations for the Raspberry Pi version, not sure yet how much effect they will have (so far only build on Windows).
- Exciter: Make 2 kHz block size configurable, or automatic, or combination. Might work best if it's constant?? --> This should fix the too bright sounds in some cases without introducing distortion in other cases. I hope...
- Exciter: Optimize for LPF setting
- Plugin -> Output level doesn't work in VST version
- MB2: Make Overview window for new Multiband! For main settings.
- Woops, wrong flag set for Exciter, dynamic Squeak mode didn't work. It does now.
- "Input without processing" doesn't work in stand alone version.
- Exciter: Add Volume slider
- Exciter: Add DIFF mode
- Exciter: Try to improve tone behavior (should also reduce whole area around a spike I think - maybe configurable?)
- Add another AM test tone, sawtooth with cut off bottom
- Add 'Forcibly remove' to AM settings? Or is this a problem with the transmitter that the tester on Radioforum uses? -> Regardless, I've added it now.
- Fixed AM sawtooth test tone, adjusted level of other test tones when using AM.
- Fixed bug in HARD LIMIT introduced in BETA027 (caused crashes).
- Added slider to Exciter to choose between a more natural spectrum which however sounds more distorted, vs a very clean sound but with shrill tones in it. Will try to get rid of this slider and automatically choose the correct setting soon!
- Polar stereo: K filter added, but output is not strictly clipped anymore. Waiting for feedback.
- Add AM test tone: Sawtooth with pause at 0, asymmetrical. LPF needed?
- Fixed crackle at startup caused by Ignore high frequencies (even if it was disabled!)
- Loading old preset from before Analog mode was added apparently loads in Analog mode! -> Works now, just no idea why??
- Exciter: Crash should be fixed.
- Exciter: Sometimes you see darker bars in the spectrum, changing the overlap back and forth removes those, so somehow some levels aren't always calculated when a setting is changed.
- Fixed crash when closing
- Exciter: Moved to separate page, for now called Absolute Highs.
- Exciter: Added GUI element to show Absolute Highs effect.
- Exciter: Broken at latency 512
- GUI: Fixed hangups caused by tooltips.
- GUI: Remove dots in changed settings for some buttons on top of the screen.
- Exciter: Made frequency range configurable!!! (Old default numbers were 8000-9000 Hz)
- Blog post pre-processing, MP3 and declipping
- GUI: Added tooltips!
- Added exciter (rest of list removed)
- Added (not yet fully ok) Polar Stereo support for OIRT FM stations.
- Error (crash) on some systems should be solved
- Show something in settings that have been changed (for example a dot next to the name of the setting).
- Add license check function: extern "C" bool stereoTool_IsLicenseValid(gStereoTool* st_instance);
- Make scope skinnable
- Bug: i found one malfunction in the BS412 Section: If your switch off the FM Option and leave the BS412 Limiter in On-Position the Advanced Clipper only works in a reduced way: You can´t change the Clipper drive even if you pull the handle. The BS412 Limiter is greyed out instead so maybe someone doesn´t find the failure. If You switch the BS412 to off everything works fine again! Just a small detail, but maybe someone will have problems… -> I think I have fixed it (but there are a lot of different combinations of settings that can impact the result, I hope I haven't missed any). The next version shouldn't have this problem anymore, also, when BS412 is used I have now disabled the Advanced Clipper Drive slider.
I've been busy hiding a lot more deprecated features (if they are set to their default value). This should make the GUI a bit simpler. Stuff that's now hidden (still there and still functional if you really want to use it):
- "Bass AGC (Old)" panel
- "Classic Multiband Compressor" panel
- "Classic Singleband" panel
- "Pre-limiter" panel (in Advanced Clipper)
- "Leif's clipper efficiency modification" checkbox
- "Composite clipping Strictness (CPU)" checkbox
- Phase rotation: ""At start of processing" checkbox
- AGC "Compatibility & behavior" header
- All Singleband and Multiband "Compressor type" (Analog/Digital) pull-downs
- Multiband and Natural Dynamics "Compatibility mode (bad)" for Flat Frequency Response checkbox
- "Bass protection (Deprecated)" header in Advanced Clipper -> Bass
- "Highs gap protection: *" in Advanced Clipper -> Highs
- "Smooth slope" in Advanced Clipper -> Distortion
- "Upsampled highs clipping (useless)" in Advanced Clipper -> Distortion
- Stokkemask: "Force Stokkemask even if not using Composite Clipping (bad for audio)"
- BS412: ""De-basser non-ITU.1770 compatibility mode (bad)"
- Right clicking now restores default again, mid or double right clicking restores last loaded preset (or startup) value.
Bug: If you use FM and Normal output, with separately processed audio for streaming for Normal output, and for FM output enable pre-emphasis but *not* pre-emphasize output, then Normal output is not processed separately!
- What is the pink line in the BS412 display? Maybe remove it. http://i.imgur.com/70mWvqp.png -> Ah no, it's the adjustment of the compressor thresholds. Needs to be added to Help page.
- BS412 has VERY narrow jump on de-basser from 240 to 250 Hz. (Jump of multiple dB's). -> No, brown line jumps but actual output is smooth, so no problem.
- BS412 bass filter doesn't use ITU1770 as it should but some weird other shape that goes up to about 250 Hz.
- Need to support 2 default values and a RESET TO LAST LOADED VALUE reset option.
- Hide not selected deprecated stuff - partially working!
- Move Copyright stuff etc. also to command line version (maybe just copy it?)
TODO:
- Voice protection in classic MB is broken. Check what changed. (Code should not have changed at all). - Hm, more has changed. Check in which version! -> Waiting for reply to question -> Compared again, and the distortion is caused by the singleband compressor that's used afterwards. Which does indeed get a slightly louder input because a (wrong!) filter has been fixed since that version.
- MB: Make Overview window for new Multiband! For main settings. Hide other windows when possible, and also make it for MB1
- Exciter: Try to reduce pre-ringing (maybe by doubling overlap? Or measure on bigger block size, then go back to smaller?)
- Exciter: Add auto-adjust HPF frequency
- Add Polar stereo viewtopic.php?f=16&t=6233&p=33031#p33031
- Put in Ben Liebrand settings for vinyl cleanup?
- Test "looper" optimization on Raspberry Pi 3
- Command line version doens't like long name (Antenne V. - see mail 2-3-2016 22:24).
- MP3?
LATER:
- Try adding phase delay compensation
- Also show tooltips for blocks of parameters.
- RDS encoder: Use Mathijs' method with interpolated 0's. Should give a nicer signal! Also I saw a weird jump bug in the raw (unfiltered) RDS output. Shouldn't matter (it gets filtered out) but still better to fix it.
- MB: Add voice volume protection, don't allow mid bands to drop below surrounding (to some extent), protectes voices and it might help to replicate the sound of certain other processors 
- Continue with finding parameters to hide
- O skin
