 Re: [Brp-pacu-info] Pink noise generator (accuracy) From: Brian Phelps - 2012-11-12 02:41:09 Attachments: Message as HTML ```It does appear that the pink noise is attenuated by some type of additive LPF action of the filtered sequence. If you read this link you'll see that the filter is not perfect but is supposed to be really close down to 9.5 Hz about +/- 0.05 dB.

A couple dB down at 60 Hz on the low end would make very little difference in TF or impulse response measurement due to the way the transfer function works. I typically use an external PN generator and I have never heard a difference between the internal PN gen in BRP_PACU and my Neutrik Minirator. The real question here is why is this claimed as +/- 0.05 dB/octave but turns out to have a rolloff below 120 Hz? Did we do something wrong in the implementation? Someone could inspect this further in Matlab and see whats going on here if they wanted to. There are other ways of generating pink noise. If someone submits a patch I'll take it ;) It could even be based on how they do it in Jabra. Otherwise I think I'll just put a disclaimer on the PN generator in the docs. The PN accuracy is really is not crucial to the intended use of the application. Other applications using a single FFT rely heavily on this though and someone could get themselves into trouble if they expect the PN to be exactly -3dB/octave 20-20kHz. So patches anyone or should I just update the docs to reflect this? ---- Sent using Manchester encoded voltage pulses over a link to form packets which contain other higher level packets along with this message and signature which also contains the IP address to the destination and passing through many router links which may queue the packets at different amounts and possibly arrive out of order only to be reordered by the TCP/IP stack in the kernel of the recipient's server and displayed by a program running in userspace on the device you are currently looking at.

 Re: [Brp-pacu-info] Microphone Calibration File From: Brian Phelps - 2012-05-14 11:01:27 Attachments: Message as HTML ```I use an Earthworks M30. There currently is no way to incorporate a calibration file without modifying source code, probably 2-3 days worth of work.

 [Brp-pacu-info] Added documentation. From: Nikolai Beier - 2011-10-25 10:48:13 ```Hello If you have tried to download BRP-PACU from git or just tried to find all the dependencies to make it compile on Linux, then the README is now much more complete, and helpful I hope. (If not, ask here by email). See it at http://tinyurl.com/65mpecr The instructions "works for me", which means on Ubuntu 10.10 at least, and probably on all Debian-based systems. RPM-based systems might have other (slightly different) package names than the ones suggested. (note the separate file for OS X.) Furthermore, I have been writing on an introduction, which might make it into a html help file. There are still some loose ends, like "What does the average buffer do?" https://docs.google.com/document/d/1oJ5NbiHjNZDFLXpfRcxqpdq6Kp2XGZUpqaljSNG3sfk/edit?hl=da Comments are appreciated. -- Nikolai Beier ```

I'm having a number of issues with gdk-pixbuf. 1st is libx11. the configure script isnt finding it. To even get that far I had to flag it --without-libtiff/--without-libjpeg. is that ok? what do i do about libx11? I'm an audio guy.

 [Brp-pacu-info] BRP-PACU From: Brian Phelps - 2009-11-09 14:21:23 Attachments: Message as HTML ```> After ./configure, I get the following response: > checking for JACK... no > configure: error: please install the jack development version. > But, to be honest, I don't know what to install. > Regards > Mathias On the web site http://sourceforge.net/projects/brp-pacu/ there is a mailing list for support, but I'll help you by email here and cc the list. What OS or version of linux are you using? Ubuntu/Debian, Redhat/Fedora, etc? With debian based distros like Ubuntu do the following: > user@...\$ sudo aptitude install libjack-dev > Sourceforge killed the wiki page, sorry! I'll find out what happened. Hosting a project on sourceforge is a PITA because they change things every month and I have a day job and I can't keep up with their perpetual changes. ```
 Re: [Brp-pacu-info] help with brp-pacu software From: Brian Phelps - 2009-10-29 14:25:56 Attachments: Message as HTML ```Hi Dany, brp-pacu uses the Jack API which can handle audio data from the network. The data is then captured (usually as a transfer function of output/input) to a "BRP" file. Or, If you are talking about capturing the trace sample data, that is stored as hex data in an array of gfloats with a header. The part that does this is in gui.c and is called "save_file". "open_file" does the inverse of save file and loads the captured trace arrays from a file. The only "commands to the speakers" is the pink noise generator. That is handled through writing to a buffer that is connected to the output buffer in the Jack audio thread callback. The function that fills that output buffer (and the captured input buffers) is called "Fill_Buffer", the buffer "pink_noise" is copied to the output buffer in this function.

 [Brp-pacu-info] help with brp-pacu software From: dany kaizada - 2009-10-29 13:24:58 Attachments: Message as HTML ```Hi, My name is Dany Kiazada and I'm a student for Communication Science Engineering at Ben Gurion Uni. in Israel. I'm doing a project about Sound Calibration, where I build a Sensor Network that comunicate with a main computer. I would like to use your software to analyze the data feed from the network, then adjust and improve the sound system (speakers). Do you think of a way to get the feed from the network, directly to the software (not throught the gui)? I will appricate a link to the part in the code that converts the input provided by the user, to the actual commands to the speakers. Is there a way to manipulate a HexaDecimal number from the network, and convert it into a value we can feed the speakers? thank you, D.K. ```
 [Brp-pacu-info] Jack stability Update, capture file saving From: Brian Phelps - 2009-04-08 14:33:24 ```Use git for the latest source git clone git://brp-pacu.git.sourceforge.net/gitroot/brp-pacu/ Version 2.0.8 04/06/2009 Added Pink Noise Menu Item and CTRL-P accel Version 2.0.7 04/01/2009 Buffer Management *Added capability to automatically save the capture buffers and load them from \$HOME/.BRP_PACU/buff_store at startup if it exists *Added Open, Save, and Save-As dialogs, functionality to store buffers for later usage/reference *Added functionality for opening data files by double-clicking or dragging into the application icon (Mac only) HCI *Put more user friendly name onto Transfer Function Button (formerly H(z) *Changed Buffer names to not start at 0, but 1, updated accelerators accordingly *Removed menu pictures because they hid the accelerator shortcut help in the menus for some reason Keyboard Accelerators *Thanks to Andreas for fixing the Mac key accelerators and suggesting the use of Control keys instead of Alt keys Minor Memory Leaks *Destroy widgets on exit only if left open Premature Memory Deallocation errors * Made colors global variables in gui.c * Made several widgets global variables Fix Jack callback stability by improving threadlock handling *Removed threadlocking around gui_idle_func (Gui Idle function) which keeps jack audio thread from updating buffers *This improves jack performance (XRuns) by preventing Jack audio buffer callback from being locked out for long periods during a gui callback *This is done by only copying critical memory areas during the thread lockout, rather than trying to update the whole gui and not make a copy, which was easier to do but not clean ```
