Adjustable audio recording levels?

Hello... and thanks in advance for any help anyone can offer

Is it possible to adjust the audio level of a voice narration or audio recording?  I'm not referring to volume but to the bass, treble, etc of an audio recording.  I have to go through and edit audio.  Which at times means I have to re-record sections I'm not satisfied with.  Unfortunately the voice narration I'm inserting doesn't sound very consistent with the original voice recording.  It doesn't have the same level of bass, treble, etc that the original audio had, and it's noticeably different.   I already applied volume leveling and noise removal but they didn't help at all.

Hello, it's sometimes difficult matching up different audio sections, especially when an edit is recorded and dropped in at a different time. It's a few factors that cause the new take to sound different. To minimize this I script and record the narration ahead of time. I listen as I record myself and if it seems off in terms of annunciation or simply the wrong words, I pause and re-speak those lines. That way everything sounds "the same" and I just trim out the errors.

I've been in instances where I have to record something over again and the decision is how much of it to re-do. I have instances where the clip is the same but I need two versions each with only a product name difference. I record these in the same take and that makes splicing it pretty undetectable. I can say you're better off recording entire sentences and even paragraphs  because then any differences are less noticeable.

But back to your original question;  what can you do to adjust your new recording to get a better match? There may not be anything that can be done. You can try to apply EQ (equalization) all day long, but the factors I've seen that influence the overall resulting sound should be considered:

 Is it the exact same microphone? Are you recording into the same PC with same input? What is the distance of the mic relative to your face? If that differs, the mic reacts to that and "colors" the  recording a different way. What mood were you in? ;) All these things add up. To combat this problem, I use the identical setup every time; the desktop mic stand sits in exactly the same spot and I use the same levels and distance from me to the mic. I close the door to lower the noise floor. This usually works.

You can spend all day trying to fix a particular clip and still not get a good match. My recommendation would be to record a new take matching all the contributing factors to the original as closely as possible.  Or do the narration completely over (whatever is the best use of time). Good luck!

If you don’t have the option of re-recording, you could export the audio edit the EQ in Audacity and then bring it back in.

Is there a free (or cheap) external program that can adjust the audio level and tone of a clip without separating the video portion of the clip? This would be important for a talking head video so audio and video still are in sync.
It is a shame that Camtasia does not have basic audio adjustments, such as a simple equalizer and an audio meter that indicates decibel levels. Even a clear clipping line would be helpful. (I think they took this out of an earlier version). I would vote for all of these features.

use free Audacity; export the audio only [Share menu], tweak in Audacity [it works great], then bring that new audio clip back in Camtasia, replacing/silencing the original audio

GoldWave is another great inexpensive audio program. Either tool means a workflow split though.
