Error on sliding time scale/pitch shift - SOLVED

[steve]

I quite understand why you prefer XP. It served me well for many years and seeing the end of XP in sight was what prompted me to switch to Linux. I still keep the old XP box for testing and have XP as a virtual machine on my Linux box (also useful for testing). At least you can still use the 2.0.0 version while we try to sort this out.

Are you aware that you can have multiple versions of Audacity on your machine at the same time?
In addition to your installed version, if you download and unzip a ZIP version to a suitable location, you can run that separately from (but not at the same time) as the installed version. To keep the versions completely separate, create a folder in the same location as the unzipped "audacity.exe" file and name that folder "Portable Settings". Any settings that you make in the ZIP (portable) version will then be written to the "Portable Settings" folder without affecting your normal installed version.

Steve:

Since I am the only one having this crash problem, then there really is nothing to sort out. Who knows where the culprit lies. what is clear is that something on my machine is somehow in intermittent conflict with sliding time scale/pitch shift in version 2.0.1. But that does not mean there is anything wrong whatsoever with 2.0.1. Maybe there is some quirk in my computer, although I have no other issues with the many software products I have installed on my computer. Again, I will purchase a new computer someday, but I am in no hurry since my current Dell is working just fine.

Unless some other Audacity users come forward with the same problem, I would just forget about it.

Again, thanks Steve and everyone else for you excellent support and a great product.

There is software available which does the same thing where I can alter the speed and/or pitch of WAV files without introducing distortion. Of course, it is not free but I will be looking into it.

You can try Best Practice to change speed or pitch without affecting the other. It is free and open source like Audacity. You can only work on and save a complete file, but you can try out the speed or pitch changes in real time.

We can easily give you a debug version of Audacity, but that would not give us the information we need without you installing Visual Studio and the SDK well.

There is very little information on the BestPractice webpage. While it allows reading directly from CD, does it allow saving to WAV? Saving to MP3 is unacceptable.

Yes it can open and save WAV files. I tried it with your example crash file.

Gale:

Thanks. I'll try BestPractice. But I will not pursue my audacity 2.0.1 intermittent crash problem any longer since I am the only one experiencing it.

EDIT: I tried BestPractice on some of the same tracks and the result was not as pleasing as that of audacity. Even the "paid" software that I was trying on a trial basis did not sound as good (there was some low-level distortion). So I will stick with audacity and if I get the glitch I'll just try again since it was intermittent.

I managed to reproduce the bug on windows vista by running the effect on infinite loop in audacity.
It is a bug with a destructor in my code - a rather convoluted one which I haven't figured out yet.
I should be able to submit a patch soon, though.
Thanks for the bug report, mdubin!

Thanks, Clayton. I started a bug for it http://bugzilla.audacityteam.org/show_bug.cgi?id=557 so please attach your patch there.

@mdubin, Clayton has posted a patch in the bug report http://bugzilla.audacityteam.org/show_bug.cgi?id=557, so would you be able to test using your usual Sliding Time Scale workflows?

To test, download http://www.gaclrecords.org.uk/bugs/audacity_bug_557.zip, unzip the enclosed "audacity_bug_557.exe", copy it, then paste it into the installation folder for either 2.0.0 or 2.0.1. Then exit any versions of Audacity you are running and launch "audacity_bug_557.exe" from the installation folder.

Gale:

Thanks very much to you and your staff for your excellent continued support.

This evening, I will follow the above instructions to paste the .exe into the 2.0.1 folder (since that is where to bug occurred) and do some extensive testing this weekend.

Will let all of you know what happens.
