Summary0008295: Zero crossing selection when resizing audio clip
DescriptionCurrently when an audio clip is resized, the user can select the granularity by choosing the snapping metric, ranging from a bar to 1/128th notes, etc, or free resizing. However, without a selection to a zero crossing, this clip can have audible artifacts. To stop this from happening, there should be a select to zero crossing function, or a very short ramp up/down envelope.

My bad, it seems like the process of selecting and moving clips, inadvertently there was a very short clip that was copied and was enough to cause a non zero crossing clipping sound. Be that as it may, having a select next zero crossing function would be great

I assume you'd like this feature to splice regions to create loops.

Despite what many assume, zero crossings is not a good way to splice regions. It can work in some special circumstances (usually when you apply a band-pass or high-pass) to track the phase of a signal.
For creating loop samples, you're much better off to add a short fade, reduce the energy of the signal instead of concatenate data using zero points as glue.

Ardour does add region-fades when you split a region. You may want to change the region-fade to be fast ( https://manual.ardour.org/editing-and-arranging/create-region-fades-and-crossfades/ )
Also Menu > Transport > Playhead > Move to prev/next transient (Ctrl + left/right) may come in handy.

PS. If I misunderstood your use-case please elaborate what you'd like to achieve with "move to next zero"

zero crossings are a bogus concept invented in the early days of digital audio.

they are not useful for editing, and DAWs or writers that claim otherwise are not being honest with you.

i will do a write up for the Ardour FAQ at some point (soon?) explaining why this is true. but trust me, it is true.

"Also Menu > Transport > Playhead > Move to prev/next transient (Ctrl + left/right) may come in handy."

This is probably the function i was looking for.

"zero crossings are a bogus concept invented in the early days of digital audio. "

I've heard about this as well. But a nice writeup would be fun to read.
