Stereo Tool

You are right, I will check it

Confirmed

Thanks!

beta 028 is the best st beta version

BETA751-029

Windows 32 bit:

CHANGES:
Added some more presets.

QUESTION: If there are presets here that should be removed, please let me know. Also if I should order them differently. I know people have asked for more info about presets, I cannot add that now but it's still on my todo list...

TO DO:
- Exception in: GUI Event Handler (Exception 0xc0000005 at address 0xf5f5b8, read/write=1, r/w location=0x0). Offset-info: 0xeb0c84. Reported by Fario and 2Sense. Unfortunately the crash occurs in a function called __intel_memset and I cannot see where it's called from. (Well, the GUI obviously...)
- Add presets, and remove a lot of older ones
- Improve web interface further. -> Postpone, can be done together with hardware GUI development. (very soon, among others preset selection)

OLDER:
Added separate FM and AM lowpass frequency setting; stream output uses a different frequency than FM/AM.
Added separate volume for 1st and 2nd MPX output.
Added Multiband Pre-Limiter. Protects clipper against volume effects (pumping) and distortion.
Added Bass Boost "Drive" slider for better control.
CPU load: Added faster processing paths for SSE3, SSE4.1/2, AXV and AVX2.
CPU load: Optimized Delossifier.
CPU load: Optimized Stokkemask (CPU load reduced by around 70%).
Delossifier: Disabled at low latencies and monitoring output (adds latency, makes no sense in lower latency modes).
Compressor/Limiters: Moved limiter before compressor. Slows down the attack speed when limiting, giving a more stable sound.
Limiters: Solved distortion when limiting bass sounds.
Limiters: Default "Limiter Distortion" values changed. Range increased downwards from 1.0% to 0.2%.
Advanced Clipper: Stokkemask: Redesigned to have less impact on the audio.
Advanced Clipper: Made highs clipping level configurable.
Advanced Clipper: FM Multipath protection: Improved the behavior, effect is much bigger now.
Web interface improved (scales to screen size, many widgets added).
GUI: Simplified tilt correction. Only one slider left.
GUI: Added CPU load display (as text) to the CPU load sliders.
GUI: FM: Add volume meters which show MPX and Left/Right above 100% modulation
GUI: Added warning that it's better to use ASIO and setting the sample rate correctly in Windows.
GUI: Changed band steepness minimum values for Multiband/Natural Dynamics from 6 to 3 dB/octave.
Code improvement: Assigned unique ID's to built-in presets, to make it easier to add, remove and shuffle presets.
Bug fix: Potential audio drop in FM output with Tilt correction enabled solved.
Bug fix: Single-channel file in plugin version caused crashes when using the composite clipper.
Bug fix: GUI: Tilt calibration was reset when loading a preset, removed.
Bug fix: RDS ClockTime summer time mode on 64 bit OS's fixed.
Bug fix: Stokkemask "Skip Smoothing" mode didn't work properly.
Bug fix: Bug that caused sliders and top menu to stop working fixed.
Bug fix: Calculation of FM MPX left/right peaks was wrong when using Composite Limiter.
Bug fix: MPX Power calculation was wrong after switching to a different sample rate.
Bug fix: Fixed broken GUI display in AM mode when in full-screen
Added new and removed old presets.

I can now confirm that the second edition of beta 28 resolved the performance problems in the DSP version, and it now appears to be exactly the same as previous versions in that respect.

WOW, when i press presets menu ... the load goes 2.5 times high ?!
Someone else to confirm that ?

DJ-DOGGY, yep, I can confirm there is a significant jump when opening the presets menu. It's not constantly "double", though. It's all over the map when the menu is open, but consistently higher. Sometimes double, but other times a bit less.

FM output disabled , FM transmitter is ON
Normal output is ON and whatever is selected (except "Input without processing") Pre-emphasis is affect the normal output ? Is this the right behavour ? I think the Preemphasis should NOT affect any of the Normal output (except the Option with "separately Preemphasised"). There is something that needs to be checked and fixed there.

And the Options for Normal output are "Grayed out" when FM output is disabled! See no reason for this .

Historically grown this way. Originally ST was a Winamp plugin, not a standalone program, and at the time I had to use Winamp to output FM audio, which would work if the sample rate was high enough. I should probably fix this behavior as part of the planned sound card handling redesign.

The only thing in Normal Output that I see disabled is the 'Signal selection'. Same reason here, the FM stuff happens in Normal Output if FM output is disabled.


CPU load with presets menu open is an old issue (has been there forever). Cause is that I need to redraw the preset menu on each screen update. (Yes that could be optimized.. but it's a low priority thread, which should normally not cause any problems). If you look at the CPU load graphs in ST only the GUI graph should go up when this happens.

yes only the GUI graph is up to 100% . This cause averall cpu load in windows to be like 2-2.5 times up in the Task manager.

I understand for the Normal output and yes i mean exactly the signal selection that is greyed out. This is for fixing, right ?

You want to say that when the Sound card redesign is happen , this issue with the preemphasis on normal output( when FM output is disabled) will be solved ?
