For simplicity, try this code on a mono track. It adds a label each time a sample is exactly zero. Works only when silent before the songs starts. Doesn't show zeros in song selections. The odds of a visual zero are a LOT higher because Audacity (and your video monitor) doesn't have as much pixel r...

https://forum.audacityteam.org/download/file.php?id=30195 That image shows the waveform in both tracks "crossing zero". That is what a "zero crossing point" is. So the crossing is anywhere between two nearest dots? Or just where the split line placed? If second than it's hard to guess it manually, ...

Does it do what you want it to do?

Looks like no.
What it does What I need

Try this version. I've also added some comments to the code that explain some of the less obvious parts: (a "comment" is text that is ignored by Nyquist and is for the benefit of anyone reading the code. Comments begin with a semicolon ";") Ok, thank you again. This code is ready to be converted, r...

Instead of "(return-from find-zero count)" when a zero crossing is found, it needs to set a "result" variable to the current "count". The loop will then process all samples in the selection (which will be slower because it can't terminate early). When all samples have been processed, return "result...

This code, when run in the Nyquist Prompt (https://manual.audacityteam.org/man/nyquist_prompt.html) will create a label at the first zero crossing within the selected audio. Thank you, but since an attack part of a sound is more short and visible than a release part, I always split waveforms just b...

Hi Need a plugin to highlight where are both stereo waveforms at very zero right at the same time. It's possible to find manually even in small selections but too long. Select > Region > Ends to Zero Crossings function is inaccurate for me as it just suggests points with least clicks. I don't want t...
