Track Height

[davegee]

Arising out of a post in "Suggestions".

This is valid for Mouse Users but (apparently) not for "Wacom" users.

The Height of a Track in the Timeline View is adjustable using Ctrl+Shift+Scroll Wheel. It can be used to quickly and temporarily adjust the Height between 75% and 400% to make accurate settings of Audio Volume easier to accomplish.

Thank you Dave, this shortcut will be very usefull for me, even if it is not sufficient to solve the (minor) problem I raised in my last video.

 

I just tried using your shortcut but I'm stil unable to find again exactly the same value.

Possibly because you are using dB and I am using %?

As I said previously, I can repeatedly achieve a "resolution" of 1% with no difficulty whatsoever and the value does not "jump" when you release the Mouse Button.

I forgot to mention that Ctrl+Scroll Wheel controls the Horizontal (Width) Zooming.

Same thing for me;, as you can see on the video.

I'll try in % mode.

Done.

If I use the % mode and zoom to 400% I am able to adjust the volume with a resolution of 1%.

But ...

I spent 50 years adjusting volume in dB, and for me % is not an appropriate unit to adjust sound volume...

[davegee]

Not sure what the relationship is between dB and % in this case but PTE (generally speaking) does EVERYTHING behind the scenes in Percentage Mode.

So dB would be converted to %.

dB=20*log(Volume/100)

It's the value (Integer 16 bits I think) which is registered not %

[davegee]

Does it really matter?

If you set a level in Decibels and then change to % you will always get a figure which is a whole number.

Example: -17.879dB = 13%

You cannot get a dB figure which is between the equivalent of 13% and 14% in decibels so it sort of proves that the underlying "resolution" is in percentage.

You can get 100 steps between zero dB and -inf dB so regardless of what the dB readout is you are working in Percentage mode.

DG

P.S. Can you find a value in dB which is a whole number?

[denisb]

It doesn't matter, but look at the figure: the same points Volume of 10% is equivalent to -20 dB

 

So may be the whole numbers for "volume percentage" are only round numbers of fraction

I "think" that if the track height zoom % is altered between adding two points of the same % value you will get a slightly different Decibel Value.

Could be a Bug or a Logic problem.

For consistent results, always use the same Track Zoom Percentage.
