Topic: StandAlone source rebuilt.

[ncpilot]

I notice that the transfer rate is consistently higher, actually achieving 16kbs, whereas before it was hovering around 13-14kbs.

But the peak meter bars are now less responsive, i.e., they don't move as rapidly as before...

I intentionally slowed down the meters.

Previously they were being updated every 40 milliseconds.

I think thay they are at 200 ms now.

Did you get the new bass.dll before trying this hacked version of stand alone?

Thanks.

[wuhu_software]

Running your "hacked" program, with the new bass.dll, I get 3-5% cpu...

But, I'm also picking up a weather station in California now... ??

     just kidding...

Given the way today is going, I would not be surprised!!

[ncpilot]

I tried the new bass.dll first, didn't notice any change in cpu.

Then, keeping the new bass.dll, tried your program version, much lower cpu.

Right now I'm averaging 0-3% utilization...

Well, I have just finished a couple more tweaks if you want to check it out.

I do not think I can squeeze any more performance out of it (given the source).

Let me know if it works for you.

If it does work, I am going to call that project complete.

Thanks!

Well... just tried your latest custom version of Oddcast, WITHOUT changing the bass.dll.  Much improved CPU usage!  I'm averaging about 7-8% CPU.  Also, this time the Oddcast software started on its own after a reboot without intervention on my part.

Only beef I have is that I did like the faster meter bars, although 40ms might be faster than we need.

I have made an installer that will install the custom version of OddcastV3 stand alone in to your existing OddcastV3 program folder. To install, download the .zip file and running the installer (install.exe) contained within.

Here are the differences from the original Oddsock installer:

1) The OddcastV3 folder will be added to your Programs listing (Start/Programs). It will also build a proper un-installer.

2) A shortcut to Oddcast will be added to your startup folder. If you created a batch file to start oddcast you will want to either remove your batch file or remove the new shortcut.

3) Installs the lastest bass.dll that drastically reduces CPU utilization.

Feedback appreciated.

New installer.

If you ran the new installer yesterday, it has been updated this morning.

http://home.comcast.net/~wuhu_software/files/OddcastV3StandaloneCustom.zip

This version may have less interaction with other Internet applications.

Let me know if you see an improvement.

Thanks.

Made a few more tweaks.

On three different computers the utilization is now < 3%.

Let me know if you have problems.

Thanks.

Very nice.

Does seem to work better than the other oddcast.

Now just add a hum-n-hiss filter.

Hey, that is not a bad idea.

I wonder if there is any open source to do that?

Audacity has the ability to clean up audio...

Maybe there is something for live streams... hmm....

[ncpilot]

Yeah, a software notch filter...

I'm still happy with your modified version a couple of times removed (prior ones)... along with the new bass.dll, I average 0 cpu...

[wuhu_software]

I have made a new version of the oddcast stand alone custom that includes a 1 pole and 2 pole filter. This is my first attempt at adding a VST filter. Free ones are hard to come by. If you know of any free VST plugins that could be helpful, let me know.

About Filter plugin:

Author homepage: http://karmafx.net/index.html

KarmaFX Filter
~~~~~~~~~~~~~~

A simple filter plugin featuring:

* One Two Pole Multimode Filter (-12dB/oct).
* Adjustable frequency, resonance (Q) and saturation drive.
* Selection of Lowpass, Highpass, Bandpass or Bandstop output.
* Two One Pole filters (LP, HP, -6dB/oct) with adjustable frequency.
* Filter series: In -> Two pole -> One pole -> One pole -> Out.
* Filters can be turned on or off (bypassed).

There is a new button on the oddcast main screen "Filter/EQ". Click it to access the filter settings.

Note that the two pole filter is enabled by default, the single pole filter is disabled by default. Since I do not understand how the dual pole filter works, on my system I have enabled only the single pole filter then set the low and high clipping.

I do not current have a way to store the filter settings so you would need to set them up after a reboot. I will look in to adding that feature if these plug-ins prove to be useful.

Umm... I'm having trouble keeping all these custom versions straight.

For the benefit of those who might be reading this thread later and clicking on the links as they go, maybe we could differentiate between them somehow.  

Also, I'm not finding the modified Oddcast file.  

Still running the previous build (March 10, 2007), with CPU usage averaging roughly 5%, and no stability issues either with my system or with the stream itself.

I have run out of space on my website, otherwise I would be labeling them with different versions. Will work on obtaining new webspace.

What do you mean you are not finding the modified oddcast file?

Did you download the .zip file?

Thanks.

Cool. I wish I knew what did what... any thoughts for a general "hiss" filtering?

I think if you limit the frequencies between 70hz and say 3600hz, that should get rid of hiss and hum.

Let me know if it works.

Ok, I was just guessing and messing around...

I turned on one pole, turned off two pole.

Low pass to 61
High pass to 38

Seemed to make a noticable difference in quality.

I was using the single pole only with the above limits (70hz and say 3600hz).

Let me know if you figure out how to use the double pole filter.

Thanks.

[NoQuitters]

I've got more than enough room and would be happy to host the modified versions for you. Just let me know.

Sounds good.

Thanks.

Single and double pole is just another way to talk about the steepness of the cutoff-- 6dB and 12 dB respectively...

For audio applications, there are opinions about what sounds best, what maintains phase, etc... probably not as critical for weather streaming...

I'll try to find some good links later today or tonight, with pictures! But you can Google for the terms and find some good stuff...

That would be great if you could find more information. I would like to understand how these filters work internally.

I do not understand why only the single pole filter has a cut-off for high and low frequencies while the two pole does not.

The two pole seems to require one of the four modes (high pass, low pass, band pass, and band stop).

Am I missing something here or can the two pole only process one end of the frequency spectrum?

Thanks.

[ncpilot]

I'll try to post something tonight or Sat...

I went to the website for the filter you've incorporated, but there wasn't much in the way of help files, or other info. Was anything included in the "package"? (from the site?)

I find the interface to be confusing, given my understanding of filters, the controls don't make sense to me... the difference between one and two pole is basically the attenuation of the frequency spectrum surrounding a particularly chosen one, e.g., if you pick a low pass filter, and a cutoff of 5kHz, a single pole will drop off the output at that frequency by 6dB per octave, a two pole at a rate of 12dB per octave. The attenuation starts at a frequency lower than 5kHz, and by the time the signal hits 5kHz, it has been reduced by 6dB.

I've got to find some pictures...


The placement of the dials under the different pole options is confusing to me...

I'll probably go back to a really old source for speaker building and crossover design from Vance Dickason...

But if anyone else wants to get a jump on me, just do a general search for crossover design...

You can go to that site and download the .zip file, other than what I posted, there is no other useful info in the Readme.

I suspect there is probably a better VST plug for this, but the free ones are hard to find.

I did find a nice 8-Band EQ, but I am not sure that would have the same effect as a good filter.

Let me know what you find.

Thanks.
