Subject:Is snap to zero-crossings working in 9.0e?

I've tried all the option switches for this on the menu and in the preferences and I can't seem to get it working.

In SF8 I would just select an area above -inf in a waveform and the selection would snap to the nearest zero crossings on both sides of my selection. I just can't get this working in SF9.

What am I missing?

While I'm here, I'd like to mention that it would be a useful function to optionally be able to have the zero-crossing find the closest zero-crossing common to both channels (ore even multiple channels) of a wave file.

Thanks!

UPDATE: It seems that the "Disable auto-snapping below 1:4 zoom ratios" option in "Preferences > Editing" doesn't work.

If I select at a higher zoom ratio the selection does snap to 0. It snaps down to 1:4 but not below. Unless there's something else involved, it would seem to be a bug.

There is a workaround: I can right click the selection and then and select "Selection >Snap to Zero". Faster the old way, though.

I vaguely remember something to the effect that is does snap- just doesn't display properly (?) . But I could be wrong.

No, the zero-selection done by mouse selection no longer works in any zoom scale. Only Z and Shift-Z work to select a zero crossing now.

Sony, please improve your QA process on Sound Forge; previously working features are being broken and not fixed.

Thanks.

It is a soft-snap in 9.0 that occurs as you drag, like snapping to markers or time.

If you are zoomed out, make a selection, then zoom in and you will see that you are on zero-crossings. If you are zoomed in, you will see the cursor/selection "snap" to the nearest zero-crossing as you approach them.

But you aren't the first to be confused by this change. We are considering adding a "Quantize" to zero-crossing feature in the next version, which is a more apt description of the old behavior.

Alternatively, if you prefer, hold down Ctrl+Shift while selecting Options->Preferences, switch to the Internal tab, and find the entry labeled "Zero Cross Snap Width (pixels)" and change it to something like 500 (less if you work at very high zoom), which will behave a bit more like a "Quantize".

Hi there- thanks for the Preferences tip. I tried out your suggestion, and it's not working yet, but I'll keep fooling around with the settings. But yes, the old 'Quantize' feature is what I'm thinking of. BTW, does the Z and Shift-Z zero-crossing select use a Quantize setting? Because that does work for me.
Best-
Zak

Z and Shift+Z are not drag operations so, yes, they are essentially "post-quantizing" the existing selection to zero-crossings.

Again, the big difference here is that now we are doing something during drag, rather than after the fact, so you can see the snap occuring as you go. The idea was that if you were zoomed out, you could be confident that you were on zero-crossings, and if you were zoomed in, you had more manual control of which zero-crossing you wanted to snap to. Clearly, that got lost in translation somewhere, hence the probable need for either exposing the snap range or making a "quantize" option.
