Stereo Tool

Exactly!! So, you know what i am talking about and i don't need to upload examples.

BETA069:
I didn't want my TODO list to grow, so:
- AGC: Separate 'Remove remaining peaks' settings for band 1 and 2
- Fixed saving of 'Advanced highs...' filter.

Winamp DSP plugin: http://www.stereotool.com/download/dsp_ ... 20-069.exe
Stand alone version: http://www.stereotool.com/download/ster ... 20-069.exe
VST version: http://www.stereotool.com/download/vst_ ... 20-069.dll
VST version (No SSE2): http://www.stereotool.com/download/vst_ ... 20-069.dll
Command line version: http://www.stereotool.com/download/ster ... 20-069.exe
Linux command line version: http://www.stereotool.com/download/ster ... ETA620-069 NOT AVAILABLE
Linux GUI version: http://www.stereotool.com/download/ster ... ETA620-069 NOT AVAILABLE

TODO:
- Fix loading changed multiband frequencies
- Add buffer and filter for SCA output (SCA1 ok, SCA2 ok)
- Finish AGC improvement - make mono value configurable (replace checkbox by slider) 1 hour --> NO, not needed - anything else needed? -> NO
- Fix Punch
- Check what to do with new filters (such as bass AGC) - keep them, remove them, change them? --> KEEP
- Save new BASS_AGC setting in VST mode
- Loudness: Annoying cracking sound in bass. Slightly present in 5.00, worse in 6.00, maybe even worse in 6.10. Only when bass is too loud. Much worse than in Final Limiter (at same input level!) - so this clearly indicates a bug. Most likely cause: The filter that was added to remove bass artifacts....... - No, it's the louder bass. But it can be fixed by changing some settings. Default settings updated, and behavior for 'not Very strict' improved. Also Deep bass boost and Very deep bass protection are enabled for latency 512 now.
- Fix crash at program close
- Fix VST plugin version (does not run)
- Dynamically drop 'Allow louder highs, even if it causes vibrations' to 0 when bass filter suspects noticeable voice vibrations.
- Reduce Loudness CPU load
- Check and remove static variables
- Finish new de-essing filter (check what to do with the settings, remove at least some!)
- Convert Multiband input to MONO, then use arrays [2][4096] --> should give speedup. - FAILED
- Natural Dynamics: Fix or remove transient boost
- Natural Dynamics: Add expected + strength slider per band
- Finish declipping filter (clipping level detection + level reduction in dB). 1. Figure out why removal of unwanted frequencies causes flat lines at high quality setting with small overlap. This causes distortion, with this fixed repairs are MUCH better. 2. Fix MP3 correction, automatically scale down when this deteriorates the sound. --> TOP part fails!
- Declipping filter: Fix low latency behavior
- Always oversample clipping (configurable)
- Declipping filter: Change detection at lower input levels.
- "Test Right Channel" in "FM Transmitter Calibration" does not work since v6.10 (standalone) (bojcha)
- Declipper window close function - check! - Seems ok
- Scopes black background?
- Add AGC start level
- Declipping filter: Add comparting of sample history to make sure loud bursts are still detected properly (now, with 16 blocks of history, 65 samples are removed even when ignoring just 0.1%). I should also check the current block (probably with a margin of a factor 2).
- Declipping filter: Use reliability of tilt detection to determine movement speed; slowly move to default tilt (configurable!)
- Declipping filter: Far too many samples are marked as 'maybe/probably' clipped. Histogram not used or not cleared?
- Declipping filter: Optimize tilt detection for performance. SSE2 for maximum. And keep separate smaller histograms to determine the maximum (should perform much better).
- Declipping filter: Cleaned histogram must be mirrorred. After cleanup, mirror center is place where SIGMA above == SIGMA below! Only use on the lower end. Then run cleanup again! The result should contain approximately the same amount of data above and below. If not, that indicates incorrect detection.
- Declipping filter: Add a long term histogram, and use maximum of short term and long term start clipping level detection.
- Declipping filter: Check if 'No declipping when tilt cannot be determined' can safely be turned on.
- Declipping filter: Add setting and saving of new sliders (history size, percentage of highest samples to drop, tilt detection range start, end and precision)
- Declipping filter: Check why higher Quality settings causes cracking sounds. Answer: Rounding error, and too low filtering values to remove it.
- Move pre-emphasis to end of processing
- AGC: Separate 'Remove remaining peaks' settings for band 1 and 2
- Channels L/R swap in stand alone version when changing filtering/quality (eldoradofm)
- Declipping filter: Optimize peak matching for performance: Move determination to extra preprocessing step; try to change if statements to min/max or something.
- Declipping filter: Change default values for Maximum distortion and Step size (see Bojcha's post) WAITING FOR FEEDBACK
- Finish blind interface WAITING FOR FEEDBACK TODO: TEST: Only display this window when needed.
- RDS issue reported here: viewtopic.php?f=15&t=3703&p=11524#p11524 partially solved
- Save all new settings, also through VST interface DONE except for Natural Dynamics
- Declipper: Fix loud bass with soft higher frequencies issue.
- Update presets? (BASS_AGC etc.) 1 day
- Natural Dynamics: Attempt to reduce number of bands by 2 (memory + cpu DIV 2), using bands with sloppy slopes (no interaction between bands -> memory usage DIV 2, out-of-cache reads gone, hopefull final filter gone too -> CPU DIV 2 again).
- Natural Dynamics: Voices, especially in chorus, still sound weird.
- Natural Dynamics: Smooth out different bands more to reduce low-bitrate-MP3-like sounds.
- Natural Dynamics: Optimize situation with no interaction between bands for performance.
- Change version number 1 hour
- Release 1 hour
- Add lowpass filter for stereo signal (will cause a lot of extra latency!) - it might be possible to avoid this latency using a Hilbert transform
- Add smarter clipping detection. Maybe something much simpler suffices: Current clipping detection with threshold + flat line detection
- Declipping filter: Automatically override the 3 clipping level sliders if the clipping level is detected very clearly (clear thin spike in sample value histogram). - NONSENSE, this is already done by the histogram function. But it can be made a BIT better - I think - by automatically LOWERING the 'always clipped' slider if a lot of data is present at the highest few bins (but care is needed for DBN - Jack is Back like tracks)
- Declipping filter: Create a new histogram after declipping, clean up and subtract from original.

thanx, but where is it ?

The BETA68 DSP link points to BETA67...

The latest betas are just perfect!

We all should make some paypal donations for a " thank you" i think.

it's time for money

I have a problem.... i have Gaps on sound by the Utilization...
if i lower the Quality, its ok...! Utilazition on ST is 47-51% without decliper.

Is that new in this BETA? Or also in previous beta's? And version 6.10?

I'll run some CPU usage comparisons (6.10 vs latest BETA) soon...

@Bojcha: I have yet another Britney Spears moment: Oops, I did it again. It's not available in the stand alone version (it is accessible via the .STS file, but not via the GUI).

ata latest betas Hasn... after 60... i tried 63 and 69 today and i have gaps..

Hi Hans. Constantly downloading and listening to the program. Good progress but it seems to me that you walk around ... I use the program's BETA620-037. Super OLL OK!!!!!. She showed normal results. In other versions there is damage to the sound. Especially the stereo effect. Circumcision is a left then a right. Duran Duran - Ordinary World Compressed bass.
