"pop" sound at start of audio after import

Hello,

I'm a long time user of Articulate and I run across a problem a few times a year. I thought I'd ask about it because it happened again today.

After importing audio (.wav or .mp3), a "pop" sound that is not in the original audio file appears for every slide after I publish it. I go into the audio editor and I see a sharp spike at the beginning of all my the slides. I go one-by-one, select the spike, and silence it. Then it's gone and does not reappear after subsequent publishings.

This has happened on multiple computers and multiple versions of the Articulate over the years. It first started happening when I began importing audio back in the previous version of Articulate in about 2009. It happens both when I did the audio myself and when I send the audio out to professionals. Again, it doesn't happen every time, but enough to annoy me.

Has anyone every heard of this before?

Thanks!

Hi Gordon,

No, I only think about it when it happens so I didn't follow up because I've been using strictly SL lately.

But I wanted you to know that I just go into the Articulate editor and edit it out or silence it for now. I've never had to re-record (or re-sync animations). That would be maddening because it could happen again since we don't know what causes it.

Hi Hadiya and Gordon,

I wanted to point you both to this blog post about tips for recording the best audio as a starting point, as I've heard of similar sounds appearing that run the gamut from being the mouse click as you're navigating through to the laptop fan being louder when the computer is plugged into a power source. I'd generally recommend starting with the easiest one to solve... But, as Leslie mentioned above, if you want to share you're files with us we're happy to see if there is something else going on.

Just for the record, I'm not having any opening pops with imported audio.

I am, however, having other problems with slide length (play time) based on audio clip length. Slide with no audio sprints through in about 1-2 seconds, then advances without completing all the animations. Put in some longer audio and it plays it all. Delete the audio and the slide sits there for the amount of time it took to play the previously removed audio.

Hi Russ,

If you insert audio into your slide that is longer than the original length of the timeline, it will automatically adjust. If you delete the audio, the timeline length will stay at the length of the previous audio and you'll need to drag the end of the timeline back to the left to match up with the last object on the timeline.  For the slides where the timeline is going through in about 2 seconds, are you able to change the timeline length by dragging it to the right (or left)?

Hi, Ashley. We're talking Presenter here, not SL. So is there some timeline that I'm not aware of? (Presenter uses PP's animation pane which isn't adjustable in total, just in terms of individual animations. SL has the conventional timeline across the bottom, akin to those in audio/video editing packages.)

I'm with you on the part about inserting audio that is longer than the "timeline" (of animations). That's what I would expect. The problem is audio clips that are shorter than the timeline. Unless I'm doing something wrong, the timeline ends (and the remaining animations stop) when the audio stops. It didn't do this in Presenter '09 and is a significant problem (unless I'm doing something wrong which is very likely).

More info on this pop anomaly. It has been introduced into one of my projects. Everything was fine until I started using Presenter's audio editor. Since a slide's length is now defined by the link of it's audio, I'm having to go back and insert 2, 3, and 4 seconds of silence on most slides so that all of the animations can complete. I've been doing this for about three hours on my current project and just noticed that the pops have magically appeared.

Looking at the timeline in the audio editor, I can see that it has made some tiny, but erroneous, shifts so that the audio of one slide has encroached into the next slide. The pop is the last partial second of sound from the previous slide.
