why is the audio sound different between a recording and a voice narration. It makes it hard to correct sound.

I am trying to dub some narration in a recorded track but the sound of my voice in voice narration and the recorded video is different.

Happy New Year - Unless you use the same microphone in the same room on the same day it's going to sound different from the original recording you are trying to update.

I record scripted narration first as that sets the pace of the clip being constructed. Sometimes I make a mistake or the product information changes and then I have to figure out how best to update my audio. I use Sound Forge externally; if you're trying to do this kind of editing inside Camtasia, your options are pretty limited.

Consider how much narration needs to be changed; it may be only a word or two but it is far smoother to record the entire sentence or two, maybe a whole paragraph if need be. If the narration is improvised, you might consider a fresh pass at the whole thing if it's not lengthy. If you share some details I'm sure the folks on this forum can make suggestions.

EDIT: Apologies I didn't address the video portion of your question; when you click on RECORD you are asking Camtasia to record video and audio. Audio can be turned off to record a silent clip but I'm not aware of an option for audio only recording inside Camtasia. You can separate the audio from the video if you want to salvage that work.

NOTE: I asked years ago for an 'overdub option' that would allow audio only recording (that I used to have in Lotus ScreenCam 95 & 98)

I may be missing something, but Isn't this what the Voice Narration feature inside Camtasia is for?

Happy new year Rick! You’re not missing anything but I’m sure I am. I’ve never used it, have you? Let’s see if she can tell us more about her process.

And a happy new year to you as well!

I actually have used it. And unfortunately, like Millie C. is reporting, I've also noticed a difference. I'm not exactly sure why. But that was back in version 6 or 7 I think.

One thing I find myself doing is just re-recording using the Camtasia recorder but selecting a super small area because all I'm interested in is the voice part.

Cheers... Rick :)

Yes I just tried it with laptop mic (under desk) and it works as a simple process. Just not my workflow. I should amend the 'request' portion of my post; it was the desire to load existing audio and then pantomime the new video track. (some screens' appearance changed whereas the narration was the same for a few years)

Assuming you are using 2018, I'm wondering if you have experimented with the Auto Leveling function? Possibly it would help?

That would make the audio level more consistent throughout each recording through compression  or similar means. Might shape two recordings to be more similar IF other factors are not different between the two; mic, room, background noise that day, distance to the mic, etc. as they all contribute to the different sound. I use the same mic, pre-amp, input settings, distance every time to minimize this.  If I have any re-takes I always try hard to get them done while everything is still setup and other factors are the same. That way when I swap out portions it's almost impossible to tell. I listen like a three head tape recorder monitoring the track, I can usually tell when a part needs to be done then and there. Keep rolling, then trim & tighten it all up to a good take.

I have tried to use voice narration to correct a small portion of audio ... same mic ...same position on the desk ... same desk ... everything as alike as I can make it and the audio it ENTIRELY different and no amount of tweaking makes it fit in.  Easier to just select a small section and RECORD and insert the whole thing .. THEN the audio matches.

I've had some success in splicing in a word or two, but I typically have to record it multiple times, adjusting my tone and pacing until it's as close to the original as possible. My voice changes day-to-day and even hour-to- hour, so replaying the recording and trying to mimic it is my best option, whether for single words or whole audio clips.

As for volume levels, I always level the volume of my recordings using the a simple, free utility called The Levelator. If my tone and pacing are close, leveling makes it almost perfect.

Although I have yet to resort to it, the best method would be to re-record everything in one session. For me, it's too much work for too little gain. TechSmith's tutorials recommend recording the audio first, then recording the video, but that simply doesn't work for me, as I inevitably need to make changes to the narration after working on the video.

I just completed a test with a very short recording. The first part is using record and the second part is with voice narration a half minute or so later. I am using a headset with microphone and made no changes to ANYTHING between the recording and the narration.https://www.screencast.com/t/0HtjjAcaEnqg

Wow - big difference! It's as if the narration option takes a different path in terms of the audio recording. Is there also a laptop mic that might be selected? In recording panel you have options for microphone array (whatever is plugged into the mic jack), recording system audio (programs running, website sounds, possibly mic as well) or Audio off.

The 2nd portion is much brighter than the 1st half; sounds like different path or mic involved to me. It may take knowing if the mic input is involved or strictly USB only and what the audio setting is. Wild guess is the main portion is system audio + USB and the narration is routing through USB mic only?

FOUND IT! I looked at the settings on the Record tool bar and the audio input for record was using the internal microphone and not the headset. I adjusted and now it is fine. Thanks for all the suggestions though.

Okay good!
