Stereo Tool

I finaly updated from beta4 to beta7.

Finaly we have bypass for FM Nice.
New IMD bass killer is nice (quick test) less bass drop anyway. Shape is better, no more 30Hz pop-up abd 160Hz area way less reduced. Nice. I kinda found 77% nice start settings.

Currently i only don't know how to set highs/rest slider. Thing is that all tests says around 400% is best. However with more clipper it sounds 'empty', and around 250% it sound much better, fuller..

Ok, it reproduced here and I've fixed it. If you make the screen bigger (but that's hard when it crashes) it won't crash anymore. But the next build will be ok again.

Hi Hans,

after debugging on another mac also with Catalina, it seams that Stereotool never asks for permission to use audio input/microphone.
That ends in a kAudio_ParamError with no reference number.

(The Console utility gives a deeper access to whats going on and are better to read than the massive scrolling "log show" command in Terminal.)

Take care and stay healthy,

For some reason i found that bass reduces highs. Something in clipper. it's something that steep reduces highs form 4-5kHz and up. Also bass does not reduce almost nothing from 1 to 4kHz.

edit:
omg, i found huge bug in clipper, atleast i thing it's bug. 2nd bass clipper adjusted to default settings. When i set always clip bellow and dyn clip below to +6 Still all same, but when i set freqs to 0 everything works fine even sound is better and there is no reducing highs because bass. Those freq sliders should do nothing if "always clip bass below" and one under it is to 0 or +6. But they are doing something they should not do.

I'm not sure what you mean. I don't see it here. Tried this:
- RESET ALL, FM on (with RDS/Stereo), Advanced+Composite Clipper on, drive +12 dB
- Test file: Tone at 100 Hz, 1000 Hz, plus hiss above 4 kHz

With that, I see no difference in output between setting both bass thresholds to +6, and keeping them at +6 and setting the frequencies from 80/220 to 0/0.

If I set the levels to -18 dB, more highs and mids get through, and a lot less bass @ 100 Hz, but that makes sense.

Was testing with pink noise.
So all default in clipper, 'always clip deep bass below" to 0 or +6, 'Dynamically reduce' also to 0 or +6. clipper around +10dB

And then when i set both freqs to 0 sound is cleaner and no distortions from noise.

Stereo Tool should ask for microphone permission, and has done that for at least a year or so (I haven't looked back further). Did you get a popup like in this page, the first time you ran it?

https://developer.apple.com/documentati ... e_on_macos

No popups. On my main mac; the last one to ask for anything was 9.63 but that one didnt pass audio.
Last to ask for persmission and also pass audio was 9.62.
So I tried a clean install on another mac, same OS version, and no popup there either.

Both running macOS 10.15.7.

Did a reboot into an image of Sierra (10.12.6) and it plays perfectly there, so its in Catalina the problem is.

Ehh, bypass should ignore Post Amplifier for HD.
