Silent finder "Nyquist did not return audio"

[bigboss1927]

Hi,

I am in the process of recording my LPs to mp3 and all of a sudden the "silence finder" in Audacity beta 1.3.12 keeps giving me the error

"Nyquist did not return audio". Uninstalling and reinstalling Audacity did nothing. I tried to change the settings and it fails.....it was working before .....what can I do?

I want to separate the songs with labels without having to do it manually.

Thanks.

Try running it again but press the Debug button instead of the OK button. If there is any text in the debug window (that will pop up), copy and paste it into your reply.

One thought - you're not using a comma as a decimal separator are you? The decimal point needs to be a dot.

Here is the error from the debugger.

Thanks for the quick reply

error: unbound function - DB-TO-LINEAR

I'm not able to reproduce the problem.

Does this happen with all tracks or only certain ones?
Could you give a step-by-step description of what you are doing, including all settings that you are using. Show me how to reproduce the problem.

Ok Steve,

Here is what I am doing.

After the LP is successfully recorded. I do go to the ANALYZE menu, select silence finder.

The settings for the silence finder are:

Treat audio below this level as silence [ -db]: 26

Minimum duration of silence [seconds]: 1

Label placement [seconds before silence ends]: 0.30 .

That is basically what I have been doing and changing the settings does nothing. There does not seems to be a way to reset the settings to default as it originally worked fine before I changed something that I cannot remember


Please note that I even trashed the whole audacity and reinstalled it. Even rebooted the Macbook Pro.

Still no go.

Thanks again for your help Steve.

Those are the defaults.

Code: Select all

Treat audio below this level as silence [ -db]: 26
Minimum duration of silence [seconds]: 1
Label placement [seconds before silence ends]: 0.3

What happens if you just select a short section of the recorded track and apply Silence Finder? Does it still produce that error message?

Hi again,

I decided to give another try and to follow your advice. I did select a short portion of audio 7 seconds and it gives me the exact same error.

"error: unbound function - DB-TO-LINEAR" from the debug feature

Please also note that I even attempted to try the "sound finder" and it greets me with the exact same error even with the debugger.

Thanks again for the assistance.

Could you check the location of the file "nyquist.lsp"
It should be in the same directory as lots of other .lsp files including "dspprims.lsp"

[bigboss1927]

Hi Steve,

I did check the location of those files, they are all located in the folder "nyquist".
This is normal isn't it?

[steve]

Could you try this test:

• Open Audacity
• Import or generate a track
• Select the track
• "Effect menu > Nyquist Prompt"
• Copy and paste this code into the "Nyquist Prompt" box

  Code: Select all

  (format nil "~a ~a ~a"(db-to-linear -6)(linear-to-db 0.5)(get-duration 1))

• Click the Debug button.

If you get an error message in the Debug window, please copy and paste it into your reply.

Also, could you upload the "nyquist.lsp" file (use the "Upload Attachment" feature that is below the compose message box).
If the forum software says that .lsp files are not allowed, just change the file name to "nyquist.lsp.txt" and upload it.
