Audio Breakup with 1.3.8

[rj7500]

Hi Gale

First of all thank you for joining the discussion, certainly the more input we have here the more likely we are to solve this.

Let's start with this recording 'glitch' which I call a skip because it sounds to me like a vinyl record that's been scratched.

I can certainly hear the glitch.....seeing it is another thing. Even expanding that particular section of the project doesn't make it obvious.

I've determined that the more processes I close, the less likely the playback glitches occur so I think we've solved that part.

All USB ports are 2.0 and the computer input from the US 122 is direct and not from a hub.

I will try the Wiki Point 11 , how much increase in latency is necessary?

This is a desktop Dell Dimension E510 and I'm not sure if it's USB PCI Card capable.

I do shut down a lot of processes when starting an Audacity project, including Wmpnetwk.exe. Assuming it's part of Windows Media Player I would guess that there's no way to shut it permanently since I never share WMP files.

I'm waiting for the 'glitch' to happen again and I'll follow Ed's suggestions to the letter, zipping the actual project folder and data folder and posting it.

Question......if I open a saved project back into Audacity, does the initial log for that project follow it, or does Audacity generate a new log?

Thanks

The Log is lost when you exit Audacity. I am thinking about creating a build which will store the Log before exiting Audacity but that has some complications. For now, the only solution is to examine the Log each time before exiting Audacity and saving the Log if it has any Error statements (other than the first one " Error: Couldn't find symbol 'MainPanelFunc' in a dynamic library (error 127: the specified procedure could not be found.)" which is not really an error). You need to do this every time because problems might show in the Log but not on Play or Save until the Project is reopened. I know this a major hassle!

FYI
Attached is a log from a brand new, unrecorded Audacity desktop. Does the presence of errors indicate that there is an inherent problem with the program itself?

That first one "Error: Couldn't find symbol 'MainPanelFunc'...", is apparently an obsolete, erroneous debugging statement (it is probably also not really supposed to be a wxLogError statement but a wxLogDebug statement which would not display as "Error:..."--I think this is a bug in the code).

The rest have something to do with an improperly configured FFmpeg library, one, "Checking that '' is in PATH..." also looks like a bug in the Audacity code (the single quote mark is obviously not right) but it is not likely to have any impact on the program--it is just a formatting error in the Debug string.

The rest of the Errors are troubling and I think Gale can get you straightened out on them. Unfortunately, I do not think they have anything to do with the complaint of this post.

Do the recording glitches (that are in the same place) also become less frequent the more processes you close - I thought they did?

You need to experiment with what works for you. Note that setting also affects playback as well as recording.

I do shut down a lot of processes when starting an Audacity project, including Wmpnetwk.exe. Assuming it's part of Windows Media Player I would guess that there's no way to shut it permanently since I never share WMP files.

I would assume you are set to share if wmpnetwk.exe is running. You can check the instructions to turn sharing on and off at http://windows.microsoft.com/en-US/wind ... hare-media .

The log entries for FFmpeg look normal to me assuming you have not installed FFmpeg.

If read or write errors are part of your problem then it would be better if you obtained the 1.3.14 alpha nightly build if you have not already because 1.3.14 has more logging information. You still need to review the log for errors (underneath all the FFmpeg stuff) before quitting Audacity.

The 1.3.14 is just a zip file not an installer. Extract the files from the zip to a folder of your choice then double-click audacity.exe from insider the folder you extracted to to launch it (after quitting 1.3.13). It will not affect any installation of 1.3.13 that you have.

You need to experiment with what works for you. Note that setting also affects playback as well as recording. ........... I'll try that

I would assume you are set to share if wmpnetwk.exe is running. You can check the instructions to turn sharing on and off at http://windows.microsoft.com/en-US/wind ... hare-media ..........................I'm not sharing, nor do I intend to

I hate to ask but what they heck is ff mpeg?

If wmpnetwk.exe still runs even when you are set not to share, I would suggest running MSCONFIG. This will save you having to manually close processes when you want to record.

As the link stated, it's an Import/Export library. Add it if you want to import and export extra formats like WMA or AAC or to import audio from video files.

Msconfig indicates that WMPNSCFG is in the startup configuration but not WMPnetwk.

Hi
Attached is a log from a project that has a repeatable glitch in it I'm also including a compressed version of the actual project. Pay particular attention to the area that occurs between 2min 25 sec and
2:30. This is where the glitch occurs.

As always, thanks to all
