Windows 10: It just hangs on the splash screen after installing with vslm_0_4_1_pkg.exe

Robert Leane — Fri, 15 Jan 2021 18:58:45 -0000

Tried on two Windows 10 PCs:
- I ran vslm_0_4_1_pkg.exe
- installed MCR
- I then run vslm.exe (from explorer, or DOS prompts having set PATH)

The splash screen quickly appears and then nothing happens:
- I have left it for literally hours
- Task Manager says it is using 30% CPU, but 0 disk or www access
- I have also tried running in Admin mode.

Any idea what is wrong? I have the identical problem on both a PC and a laptop. Running Win 10 64bit Pro

Any help much appreciated!

Can you please give me more information about what is not working?
What operating system are you running?
What errors are you getting?

I am not be able to install the download vslm_0_4_1_pkg.exe
Please advice

I'm sorry to say I don't know. The package is quite simple except for the matlab runtime library which is a second fle that needs installation. I am not enough of an admin to know what can and cannot be deployed by MSI. I would guess it can all be installed via command line and hence put into an MSI package but I cannot do it and cannot guarantee.

Sorry

Can this be deployed via MSI.

Thank you

Different Measurement values for different calibration sounds

Sebastian/Ralph,

I am trying to use vslm to generate dB levels from high quality wav files from my new Sony digital recorder. I could not find any info on how to get or generate a calib file. While I have been an electronics tech, I have no experience in sound theory. I have the program installed and it appears to accept files, but I can't work without a calib standard. How do I find or generate a calib file? Are there any online tutorials in this particular task that would be relevant?

My purpose is to analyze the LPCM 16bit files with vslm to get dB readings that would let me know if the sociopath who is allowed to beat on my ceiling while I'm trying to sleep is violating local ordinances. (police, strata & property manager just ignore my pleas) Without legit dB readings, I can't get any satisfaction. Please help me.

Thanks ahead,

Brian

Hi Ralph,

Thanks for your reply - and sorry, this indeed then seems to be our fault. We recorded the calibration files and then the sounds to be calibrated - and noted that from a certain volume they clip and so we recorded everything at a lower level. However, never checked if the calibration files clip (at least can't remember the marantz showing it) and never even had a look at them in audacity, just the to be calibrated ones. We're recording everything again this afternoon, will update you if we were successfull this time.

Thanks for your help!

Hi Ralp,

thanks for your quick reply. It's indeed strange - though prob just some stupid user error. Attached here are two of the calibration files. Both were recorded on a Marantz PMD661, connected to a Brüel & Kjær 4100 - Sound Quality Head and Torso Simulator recording a from a Brüel & Kjær Sound Calibrator Type 4231 (which produces a 1000hz 94db and a 1000hz 114db signal, with an adapter thats adding another 0.5 to both. We then placed headphones on the torso simulator and recorded our to be calibrated sounds on the Marantz as well.

Thanks for your help.

That is definitely strange behavior. Can you make the cal files available somehow I can take a look and try myself to see the behavior? Maybe you can reply to this email and add the files as attachments?

Thanks,

Ralph

Hi,

was looking for a tool to calibrate the sound level for one of our experiments - we'v recorded 2 sounds from a calibrated source, 94db and 114db, and then sounds played at different volumes in order to calibrate the playback level to be at 104db. If I use the 94db cal, and measure another 94db cal file i get 94db, and if I use the 114db cal file and measure a 114db file, I get 114db.
However - If I use the 94db calibration file to analyse one file, I get a different sound level to using the 114db cal file and measuring the same file.
Also - using the 94db cal file measuring the 114db cal file I get 96db, and using the 114db cal file and measuring the 94db file I get 96db as a result.
Any advice why this would happen (I take it there is some scaling done when converting the 16bit wav to matlab matrix - might this be the problem?) / which cal file measurement values I should trust for getting a reliable 104db reading?
Thanks for your help!
