Stereo Tool

camclone still thinks he is the centre of the Universe.
LOL

@ camclone

Instead to decide that the project is finished, you should consider to send Hans some bottles (good !) Ouzo for his unbelievable quick response.
I guess you have enough money from the European Union financial help for Greece - so send something back of it in bottles to the Netherlands !

Compare Hans' quick response with the situation in the Breakaway forum and the reactions you get there from Jesse or (the invisible) Leif.
There it is even forbidden to ask when the new version will arrive ("Stop begging !").

Hans has created with his open minded Stereo Tool project a place like Paradise for (low cost broadcast) audio processing !
So it is a little bit odd that Bojcha complains that an (expensive) Omnia processor can something (clip) better than Stereo Tool.

Bojcha, do you want that Omnia goes do bankruptcy and all these people will lose their job, because Hans is such a genius (with your help !!!) ?

heh ...
Actually i did not mentioned "Omnia" for a good reason! I mentioned Orban and BBP.
Reason is that Omnia does not have this Clip system (atleast like bbp an orban)
it seems that you also think that this "Cliping" vs "Distortion Cancellation System" is Good (expensive) thing (?)

requests:
For example, You know that we (users of stereotool) request "multiband ratio" and/or "multiband expander" and many more things (me most), some of them are done, some of them done but not 100% functional, and again some things are not.

Finaly, it's on Hans it will make it or not.

- Is this ('metal tank') for bass sounds or for all sounds?
- Could you try to explain what you mean by it exactly? (I read 'suppressed reverberation in loud bass portion' in Phoenix's post, but I'm not really getting it yet).
- Is it new in the last few BETA's, or also present in older versions?
- If only for bass sounds: Does 'bass boost' make it worse? (or cause it at all if Loudness is not used?)

- I have focused on bass sounds only, let's say 0-350Hz.
- First word what cross my mind for bass was "metal-tank".
* Easy to hear, (at my AKG K26P) Last short bass-beat track i sent you, listen it in ST and bypass - can you tell me the difference?

- This is from always, but even more if you set "Clip lowes bass.." and/or "Then Rize to (static) Lower then 1.00
- I have a feeling, that, multiband, multiband-clippers, loudness, Final Limiter, Hard limit, all makes a bit and all together makes bass to sound like this. Multiband mostly! which indicates story from erlier "multiband is too much closed by this fixed ratio setting - bass"
Bass Boost actually works great! (when it's well tuned)

Clear, you're hearing distortion at too high frequencies. Based on the track you (Bojcha) mentioned, I've configured bass boost with settings: 0-120 Hz, 120-220 Hz.

However in Loudness much higher bass frequencies are boosted.

I went back a few versions and the sound is MUCH better than in version 4.xx (and insanely much better than in 3.xx), but - probably due to the improved AGC, slightly worse than in 5.00.

I might have an idea to fix it, but I'll have to check if it works and it will reduce the bass level (don't know how much).

This is it: Currently LARGE differences can occur between the amplification of different bass frequencies in Loudness. The solution would be to find frequencies that are (relatively) amplified more, and reduce them.
Edit: Actually I'm now thinking that this could also work for other frequencies...


Ow, and the filter that I created after version 4.xx to remove the pre-ringing for bass sounds does NOT work for Loudness... (Hm... Maybe I could fix that as well)

Now building a new version with improved bass processing. The output bass level is a bit lower (but there's a new 'Dirty bass' slider, if you set it high enough you'll get the same sound as before.)

IMPORTANT: Turn both "Improved loudness distortion protection" and "Very deep bass distortion protection" OFF!!! They still cause annoying bass effects - I think I'll have to remove them...

And here it is (see previous post, improved bass):

Winamp DSP plugin: http://www.stereotool.com/download/dsp_ ... 510-45.exe
Stand alone version: http://www.stereotool.com/download/ster ... 510-45.exe
VST version: http://www.stereotool.com/download/vst_ ... 510-45.dll
VST version (No SSE2): http://www.stereotool.com/download/vst_ ... 510-45.dll
Command line version: http://www.stereotool.com/download/ster ... 510-45.exe
Linux command line version: http://www.stereotool.com/download/ster ... BETA510-45 (not built)
Linux GUI version: http://www.stereotool.com/download/ster ... BETA510-45 (not built)

Basically I take the loudest bass frequency in the dynamic part of the voice vibrations filter, then I clip and measure how much softer it got. I then lower the whole dynamic part that much. (Or less if you allow some 'dirty bass'). NOTE: ALL the % values on the right should be multiplied by 100! So for example 'dirty bass 0.20' means 20%! (which also means that the bass level might be upto 20% higher!) - say I measure that I should lower the bass by 50% then a 'dirty bass' of 20% means that I actually lower the bass to 60% (50% * 1.20).

'Account for highs': set this to 0 to ignore highs completely, or 1 to drop the bass further if the highs cause a bass drop (this results in cleaner bass sounds, but also in more annoying volume effects when high freqs are present, high freqs = as defined in the voice vibrations filter, so usually above 400-800 Hz).


Edit: I think 'Account for highs' must be set lower than the current default value of 50%, I'm getting bass drops on loud 'S' sounds. 0% should work fine. Also I think 'Max highs burst strength' must be set higher for FM presets (I have it at 200% here now).

I am about to recommend ST to an internet radio station having 10 DJs an none of them have heard of about ST or even speak English.

I gave them a demo and they were totally amazed. Unfortunately, none of them are English-speaking and need the documentation in German for them to benefit fully. ST certainly doesn't require a "monkey see, monkey do" type of learning process with respect to ST.

It is critical for you to start and concentrate on the documentation and in particular with examples explaining the default settings.

It is pointless IMHO to mention ST when there is no documentation. It is even worse that when (a) one goes to the web site and finds documentation that at the moment has no relevance (b) the same is with when ST is open.

I like many other have in almost cases it was trial n error that got the setting as we wish/want to have BUT that is inadequate for what I believe as an invaluable product either FM or SAMBC. Giving the tool to the average user without documentation is totally fruitless. Not everyone is technically savvy some more than others but in the general case they require in part the assistance of the documentation in the first instance.

If you recall that 2½ yrs ago i did offer to help with the documentation and with the translations. The offer still stands as now I can make an "online flip-book" for you that you just have to place on your web site. All I need is the PDF for the documentation, once on the web site it can be viewed by the visitor and for those who are registered users be made available for d/l then when changes are forthcoming it is a simple matter of their addition.

Here are some recommendation that I would like to make to you for you to consider. I was happy that you had accepted my previous recommendation that I had made 2½ yes ago for this forum.

(1) create a separate section upon which there are two subcategories
a. for just the beta release versions their change-logs etc. and other relevant/significant changes/developments
b. discussions for for beta releases
(the current section having a page listing size is 54 and IMHO too large)
(2) consider the possible of also having a site license for an internet radio station that has several DJs who all are able to
use ST for their broadcast, in this case I am referring to SAMBC users. The site registration will have not only the radio
station's name but also their URI; this will prevent a DJ who ventures to another or creates their own internet radio
station to use the ST. In addition, it could also be registered to the audio stream's IP address.
(3) I am sure that someone like Botcha ( I truly admire his knowledge) could even help/assist in the documentation by
making videos that is to say tutorial videos for the various sections of ST IF either is in flv or mp4 format then I can
implant then into the 'flip-book' as well.

Granted, the in the initial sense it will take more time to establish or create the associated documentation BUT when all done then further or future additions will become that much easier or even second-nature.

Food for thought, Hans

Here is a screenshot of the beta being used.

Of course the setting will and do vary with other systems.

These are the ones that I am currently using

This is definitely no go.

- Again not so strict limit of lows
- Now even clearer i can hear some *pre-sound" before High Bass punch. Like i use some low quality processing.

To clear about Bass clip:
- "Then Rize to static" 30-40% - Bass should not clip like that. Sinusoide must never not be like this (negative - that's word i guess) - center of peek to be down:

But like this:


I would have installed the BBP and looked at how it works and sounds.

- Good and i think better is Highs and Loud "S" sounds - more steadily (at least with my current preset at transmitter)
- Clip Lowest bass is not reacting on bass sounds if only bass sounds are present - good too.
