Re: View all Effect changes in a project

No there isn't. The closest to that is "View menu > History" (http://manual.audacityteam.org/man/view ... ml#history) but that does not give detailed settings and there is no "export".

Re: Sample Data Export/Import is “bit-perfect”/lossless?

“.100g” means 100 digits will be printed after the dot, right? Not quite. It means, use the shortest representation: %e or %f, with up to 100 digits, including digits on both sides of the dot., where %f is floating point notation, and %e is scientific notation (mantissa/exponent). 32-bit floating p...

Re: Silence Marker Plus (a Silence Finder modification)

Another bug (which also exists in the original code): ;Create a function to make the sum the two channels if they are stereo (defun mono-s (s-in) (if (arrayp s-in) (snd-add (aref s-in 0) (aref s-in 1)) s-in)) Why would we want the sum of the two channels? Wouldn't we want the absolute maximum (ignor...

Re: Silence Marker Plus (a Silence Finder modification)

I can't even edit my own messages. Generally it's better not to edit messages after they have been replied to, otherwise the topic threads rapidly become impossible to follow. If you need to correct something, better to make a new post with the correction. By the way, there has just been a glitch o...

Re: Silence Marker Plus (a Silence Finder modification)

The "SND-AVG" function performs a kind of resampling (http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index692) The selected audio is resampled to a fairly low sample rate before being analyzed, so that there are less samples to analyze (the actual analysis loops through one sample at a ...

Re: Best quality audio format/rate for websites

The only thing that sample rate affects, is the available frequency bandwidth. 44100 was chosen as the standard for audio CD because it was "just enough" to capture the full audio frequency range. For the filter technology that was available at the time, 44100 Hz was arguably a little on t...

Re: Sample Data Export/Import is “bit-perfect”/lossless?

I wasn't sure if Nyquist supported this notation, but it appears that it does:

Code: Select all

(setf *float-format* "%.100g")
I think this should ensure that enough digits are printed in all cases.

Quite possibly, but my job here is to keep the forum running as a safe and useful resource for Audacity users, so I'm not going to ignore 30+ virus checkers. I suggest that we put that behind us and move on.

Re: Silence Marker Plus (a Silence Finder modification)

Silence Marker Plus Marks silence in more ways than default Silence Finder I'm sure that some Audacity users will find these additional options useful. Perhaps you could provide a little documentation to explain what the new options are and how to use them? (the wiki has examples of concise plug-in...
