Re: Why mono for the Pan effect?

I have been wondering why the heck the "Pan.ny" and "PanRamp.Ny" plugins are designed to make the stereo input sound mono before panning left or right? I presume that you are talking about these effects: http://wiki.audacityteam.org/wiki/Nyquist_Effect_Plug-ins#Panning There's n...

Re: AFSK generator?

Currently, my output creation is floored since I use 'seqrep'. It seems to me that Nyquist has some memory leak there. I had a stack-overflow error once If I recall correctly, seqrep is recursive, so not suitable for a very large number of repeats (stack-overflow). I don't recall how big Nyquist's ...

Re: AFSK generator?

I've chosen a Gaussian FIR filter instead of an IIR. Yes, I'm cutting corners with the IIR filter (pun intended), but in terms of reducing sideband power it is pretty effective, and it's very simple code (because Nyquist has Butterworth filters built in http://www.cs.cmu.edu/~rbd/doc/nyquist/part8....

Re: Transposition of the harmonic series

Change Pitch works by addition I don't think you're really interested audacity novice, but for the benefit of other users, that's wrong. Transforming sound in a manner that changes frequencies by a specified amount (addition) is generally called "Frequency shifting". This is distinctly di...

Re: 4 GB 44100 wav file opens 6 minutes only - help needed

a 10+ hr session gave a 4,5 GB file which seemed to render flawlessly The WAV format is limited to files that are less than 4 GB, because of its use of a 32-bit unsigned integer to record the file size header https://en.wikipedia.org/wiki/WAV#Limitations To work around this limitation you need to u...

Re: Extract Audio From Video - Manipulating - Reapplying 2 V

Some background information first: * Audacity cannot import video and cannot do anything with video. Audacity is an "audio" application. * Audacity does not operate directly on files. When a file is "Imported" (including using the "File > Open" command), Audacity copies...

Re: Insert silence

However, everything in the "Generate menu" is grey .... In Audacity 2.1.2 and earlier, playback must be "stopped" (not just "paused"). To "stop" playback at the current cursor position, press Shift+A. In the next version of Audacity (2.1.3), you can do what y...

Re: Installing LAME recorder with students

LAME recorder I think you've got the name wrong. Either that or you are talking about a program that I've never heard of. "LAME" (the name is just one word) is an MP3 encoding library. It's not a "recorder". Most of them use MacBooks, and most of them have the latest OS X (Sierr...

Re: Insert silence

The longhand way: 1) Click on the waveform that you want to insert the silence, 2) Generate menu > Silence 3) Set the duration of silence required, and click "OK" 4) Repeat steps 1 to 3 for each silence. The shorthand way: Do this ONCE for the first silence: 1) Click on the waveform that y...
