Audacity Forum

Thanks for the responses. My computer is pretty stable overall. I have more crashes in Firefox than in anything else, but I usually have 20-30 tabs open at the same time, so that's not surprising! The problem with Audacity has persisted through several computer restarts. I do not (intentionally) use accented characters at all in file titles. Some have spaces (since I'm on a Mac, that's never been a problem since 1988!) but other than that I use only letters and numbers for files and folder names. I do use ƒ for folders -- could that be enough to cause Audacity not to be able to open files?

Please see this message: http://forum.audacityteam.org/viewtopic ... 94#p222494

Gale has posted a patched version of Audacity that apparently fixes the "crash-on-import" issue. If you have the time please download and test it with various files.

Thanks.

"Buzz Tone" is not one of the standard effects shipped with Audacity, Where did that come from?

"Buzz Tone" is not an effect; it's under the "Generate" menu, along with "Chirp", "Noise", "Tone", "Risset Drum", etc. It came with Audacity 2.0.4. It is (according to the description at the Audacity page) a tone made up of a fundamental and it's overtones, with a nasal tone, depending on how many harmonics are selected.

I can see no "Buzz Tone" under the Generate menu in a standard installation of 2.0.4.

The word "buzz" does not occur in the Audacity manual in reference to a Generator.

What "Audacity page" are you referring to? Where did you download Audacity from?

That sounds like the Buzz tone generator that is available as an optional plug-in from here: http://wiki.audacityteam.org/wiki/Nyqui ... _generator
I've just checked the Audacity source code (http://code.google.com/p/audacity/sourc ... 2Fplug-ins) and buzz.ny is not included in the official release version of Audacity.

Whoops! Steve's right, I did download a few "extras" and put them in my plug-ins folder, allong with the rest of the .ny files. Still, if it's designed to produce a tone, why would Nyquist return an error of "...no audio"?

I went back to my original (2.0.3) Audacity and tested the "Generate" menu. Everything worked except for these three, with corresponding error messages:

Click Track
Nyquist did not return audio.

Pluck
Nyquist returned the value: 0.000001

Risset Drum
Nyquist returned the value: 0.800000

Since I don't know anything about the "under the hood" working of Nyquist, I'm not sure what the significance of each of these it, or how to fix the problems. My appreciation to all of those of you out there who spend the time to help out!

I've just tested "Buzz tone generator" from http://wiki.audacityteam.org/wiki/Nyqui ... _generator
In Audacity 2.0.4, the default settings of "Buzz tone" generate 5 seconds of "buzz".
When using the debug button, the debug window is empty (as it should be).

That is what is very strange, just as this was:

djblanch wrote:...I got another message: "error: unbound function - GET-DURATION".

"unbound function" means that the command is not defined. In one case the command is "MULT" and in the other the command is "GET-DURATION", but these command are defined as a standard part of Nyquist. For some reason your installation of 2.0.4 has part of Nyquist missing, just as your installation of 2.0.3 had part of Nyquist missing. How can this be happening? Are you sure that you are installing Audacity according to the instructions (http://audacityteam.org/download/mac)

It's pretty hard to screw up the installation instructions on a Mac:

"Installation instructions (.dmg files):

Double-click the downloaded .dmg to mount it
Then to install Audacity, copy the "Audacity" folder from the newly mounted .dmg to /Applications or any other location of your choosing."

Yup, that's what I did!

But now, another problem has snuck in: Since I downloaded and ran the revised version 2.0.4, I can no longer import sounds when I run 2.0.3! (Yes, I quit 2.0.4 first.) It must have revised the prefs somehow, or removed something important, or ????????? I'm not knocking progress, but I'm not seeing it, either. :0(
