Stereo Tool

I also have some little suggestion
If someone use or make his own skin , let the ST to search a folder named "SKIN" in the ST install dir, not in the main one.
I make this suggestion because if we put whole 190 files in the main install folder , it will be "ugly", so many files ...


Edit : And some other bug . When you use "Lowpass" in the FM transmitter panel together with "Ignore freqs" (main Bandpass is OFF and must be OFF, so this can be reproduced), there is a spike like before , but this time it`s not exactly on the "end frequency" of "Ignore freqs" option but arround 500Khz above it. It`s moving again when i move the slider of "Ignore". And again it`s getting weak with increase of frequency. Picture is made with slider of 16200.

Spike presented both in 44.1 and 48 Khz sample rates.

In Wavelab 6 also occurs.

I've have another problem with the VST plugin...

There are randomic clicks using declipper + dequantizer + natural dynamics in Foobar with its output buffer lenght set to 50ms.

It seem related to somewhat like latency peaks, in fact it mitigates or disappear increasing Foobar's buffer or reducing Stereotool CPU load.

Version 7.60 does not have such problem, worked and sounded great with 50ms buffer and same Stereotool settings, both 7.70 and 7.72 have it.

Hm, I would expect the opposite - 7.72 has a much lower CPU load. Latency peaks might be an issue though; Stereo Tool operates in bursts so if your CPU isn't very fast it will - for every 42 ms of audio (at default settings) - take a while. Does lowering the Latency in ST help as well?

The CPU is a Intel Core i5-3330 at 3GHz and with version 7.60, which have a much higher CPU utilization, the problem it's not present.

The sound card is an ESI Juli@.

Clicks seems randomic, not periodic.

I would guess it's related to the CPU load at the moment a new burst ends/starts.
Yes but it's different for 7.70 and 7.72.

In 7.70, lowering to 1024 mitigates the problem and even better at 512 samples the problem it's rare but still present.

It's really weird at 2048 samples, in the right channel sound is completely distorted...

In 7.72 things goes better even using 1024 samples but 2048 still result in distorted sound on the right channel.

I've also noted another thing... clicks are present randomly at left or right channel.

I experienced something similar like that except I never monkeyed with the CPU load (max.) and kept the sample size at the highest amount allowed and my CPU is very weak one in comparison to what you have. I don't use very much compression (even though my CPU can happily handle a lot more) and like to stay away from very aggressive forms (can also handle that) of it to the max a transmission medium allows. The only thing that takes too much CPU where it stutters is using the composite clipper. Still the load is about 75-98%. The newer version saw a drop to 40-80%.

In 7.70, never occurred.
In 7.72, occurred but unable to reproduce it until now.

EDIT: Well no wonder why I wasn't able to reproduce it. I probably caused the resampler plug-in to reset it's settings back 44,100 Hz and once I set it back 192,000 Hz it came back and didn't realize I might of accidently did this. I just thought of checking everything over just now, now that somebody else mentioned something similar. Very embarrassing.

Hi,

I'm seeing the same things in Foobar (both window size and clicks). CPU is i5 2500K (4 cores, 3.3 mhz).

To all that see clicks :

Try to disable some options and filters and see if clicks disappear. Also disable some other plugins in foobar (if you have such).

I just try with 7.71 VST and see NO clicks . Will try with 7.72 to see.
Edit : With 7.72 i still don`t see something to worry about.

Ok I'm trying to make sense out of this so I'm browsing back to previous posts to get the details.

@ClaveFremen: You're reporting completely distorted sound at latency 2048 in version 7.70. Version 7.70 has been available for months and you're the first to report this, so whatever you're seeing doesn't seem to happen to a lot of people. You are also saying that the problem disappears if you increase the buffer size in Foobar, which would seem to indicate that it's a buffering problem - but if the right channel is completely distorted it doesn't seem to match that (depending on what you mean by distorted - is it too loud, or a complete mess of different chunks of audio, or noise, or something else?). Can you try if that also disappears if you increase the buffer size? If not, can you make a recording of the distortion?

@Chibisteven: This is still with that very long chain of filters, right?

All of you: Are you both using Foobar with a VST wrapper? @ClaveFremen, Chibisteven only sees a problem with 192 kHz sample rate, what sample rate are you using?

I've just installed Foobar + VST Adapter, and running the latest ST shows no problems, except indeed when I set the latency to 50 ms. Then anything I do on the system causes brief drops.

192 kHz sample rate does it all the time, but that's because the CPU load on my laptop (on battery) is getting close to the maximum.

Just to check: If you are talking about CPU load, are you checking the meter inside Stereo Tool or another tool? Only the value inside ST is useful to determine if there's a problem. It's under Configuration -> CPU & Latency.

I'm not hearing any distortion on any channel, and no clicks (except small drops when the CPU load meter in Stereo Tool exceeds 90%).


Edit: I see that Foobar crashes when I open and close the VST GUI and then close Foobar. It appears to be an internal Foobar error though - it's definitely not something that's coming out of Stereo Tool... (It complains that some object already exists, a bug coming from ST would look very different, and when it happens ST has already been unloaded). Despite that, can you try if you also hear clicks if you never open the GUI?
