Audacity 2.1.2 Alpha (I built it myself from source Oct. 26) has been running quite well on El Capitan 10.11.1. Yesterday in editing a recording of a sermon I ran across one spot where it appears as if the data was just not recorded. When listening to it, it sounds like 1/2 a syllable is missing. I don’t see how a person could have spoken like that. I’ll attach a screen shot of the location zoomed in as well as a recording. It was in a quiet room so almost zero background noise as you can see then the data starts halfway up the scale. I saw something like this a few weeks ago and thought I had messed up in editing. This time I still had the original unedited recording and it is there so it’s not anything I’ve done to it. Having it once in an hour long recording seems strange as nothing else was going on at the time and through much trying Audacity seems bullet proof on this system regardless of load of any sort. I suppose it could be some outside interference as I am recording with a wireless mic into a receiver with line-in into the MBP, but to have it so short seems unlikely to me. With it being so totally random it seems it may be impossible to track down unless someone has also seen a similar thing and figured it out.
I have app nap off, but I put the display asleep at the beginning of the recording. For a couple of months this has not been any problem. I can keep the display awake to eliminate that possible problem, but that’s the only thing I can think of and it seems unlikely to do a one shot thing like this.
So the problem is either side of 3 seconds in the unedited recording?
No, the problem is at 3.225 sec. into the “improved audio” which is at 54+ minutes into the full recording. I just copied the immediate area around the problem so you could hear the lead in to it. If you open the recording in Audacity and zoom in you will see the area that I showed in the screen shot, though the screen shot was taken after amplifying to 0 db. Maybe I’m being too picky, but it sounds to me like the initial sound of the “f” on the word focus is missing and it strangely starts with an explosive sound which is normally in the middle of the “f” sound. Looking at the wave form zoomed in shows a sharp jump, not a normal ramping up that normal speech usually has.
You know that preacher’s delivery better than I do, but to me, most of “your” before “focus” is missing. Why would he pause between those two words?
That pause is normal for him. He uses lots of pauses and it makes it time consuming to edit because in those pauses the mic often picks up audience noises that I have to take out. I listened to the context from further before and there are no missing words, but just the initial sound of the “f.”
