Puzzle over setting audio effect

terrypin wrote on 8/29/2015, 1:05 PM

I've digressed again from my current project to experiment with a topic I'm relatively unfamiliar with: adding audio effects to my microphone narratives. I have the original recording in my main tab. (It has a little mains hum I want to remove, but that may be the subject of a later post.)

To experiment with different effects (and also settings made via Audio Cleaning > Equalizer > Presets) I copied the original several times in the tracks below and used S and M (not S&M) to try the various results. All that worked fine, but soon became messy:

So I copied the original to my WORK tab (having emptied it first) and made copies alongside But I'm mystified that applying any effect to these with Load Audio effects has no result! The audio is unchanged. The waveform and the text remain unaltered.

Is there something very basic I've missed here please? Is there perhaps a rule that edits to added audio objects can only be made in one place?

Hi Terry,

I'll get back to you on this. I have to get back to the plumbing.

Did you try the external editor (Music Editor 3). There are some tricks involved, but you have more control over the outcome. It's normally used at the end when everything is mixed properly.

Hi John,

No rush, it's just a puzzle, not a practical problem.

Also, further tests tend to confirm that conjecture I made about the underlying cause. Here's a simple demo that works consistently for me:

1. Place any audio clip in Movie #1.

2. If you haven't yet done so, create Movie #2.

3. Copy/paste the clip to Movie #2

4. Apply an extreme effect, say Helium to it in Movie #2. It doesn't work.

5. Select the original clip in Movie #1 (to which no effect was applied). The effect can now be heard.

So it seems that the clip is associated with the movie in which it was first imported (created?). Any changes will then only be heard in that movie.

Hi Terry,

Congratulations, you found a bug! It is the same in 2015 and VPX7!

Worse, loading effects in a second movie does not seem to work. Selecting the effect from the presets works, but not loading. Thus, any saved sound correction effects would also not work in movie 2. I tried creating a reverb in Movie 1, saved the effect (Cathedral actually) and then loaded it onto a different clip in movie 2. Nothing. Tried my own reverb effect on clip in movie 1, saved, loaded it onto different clip in movie 2, nothing.

However, I tried a different clip in movie 3 and loaded the effect ok. I went back to movies 1 and 2 and did more testing. It seems that if the clip showed up in movie 1 and then 2, it would not take on the effects in anything other than movie 1, even if the clip was deleted from movie 1.

Convoluted nuances, but a bug nevertheless. Needs more testing and careful documentation to accurately describe the problem.

Morning John,

Thanks for the testing and thorough feedback.

I'm not yet 100% sure it's a bug, or some weird design rule, but I've reported it to Support.

Appreciate your taking the time and trust the plumbing issues have been resolved!
