Hi
I have a video containing discussion between two people.
The sound is not that good, I used Audacity to remove most of the background noise.
The result is much better yet I have 2 issue I would like to improve.
1. Sometime the talking a bit tinny.
2. One of the persons volume is a less high, and I want to make it higher, if possible.
Can anyone tip me if and how I can improve these issues

1. Sometime the talking a bit tinny.
I'd try different filter settings.
2. One of the persons volume is a less high, and I want to make it higher, if possible.
If you could upload a maybe 30 second sound byte from the original recording, others here could probably suggest specific suggestions to improve the audio. Generally, less filtering is better, sometimes the best you can do.
But Audacity has lots of options and there may be
better ways to filter. -
If voices don't overlap, you could ride gain.
You may or may not be able to get better sound overall by partial reverse/compensating eq. If data is no longer there, you cannot really get it back even with subharm/superharm excitation synthesis.
Plus, this tinnyness may actually be due to comb filtering, making things much more complicated.
Can you post a source clip?

This is the first time I do it, so I am not familiar with most of what you suggested.Before posing I was trying to understand a bit more, but as you say, it is a complicated tool... So if it possible I need a bit more guiding regarding the "how"..
What I did after extracting the audio from the movie using Microsoft Movie Maker is
1. Open it using Audacity
2. Found a very short (maybe a second of silence) to get the noise profile (Effect -> Noise Removal -> Get Noise Profile)
3. Select all and Effect -> Repeat Noise Removal.
I tried it twice. First with default values. Second time reducing Noise reduction from 25(default) to 20db. I felt the result was better the first time.
So,
What are the filter setting, and what to (try) change?
There are not two channels, but I would assume and of course I might be wrong, it is possible somehow to "normalize" the overall volume of the video.
Meaning, to define some high-low volume ratio or level, and let the audacity do its processing, without really identify who speaks each second.
Maybe this what Scott target in his answer.
As for your answer scott..
Im so sorry but all the technical terms are currently inscrutable to me
I uploaded short audio track..Although I think in this fragment the woman relatively sound clearer comparing to other times along the track, yet with lower volume and less quality comparing the man. I still prefer to upload this one hoping it will be good enough sample -

If you're really using 20 as your noise removal setting, that number is way too high. Use a much lower number. As I mentioned, I use 3. And use it several times. I also use 3 for sensitivity and 3 for frequency smoothing bands. Even so, though, the noise level (especially after using Levalator on it) is just too high and I don't think you'll be able to successfully remove all of it.
I sometimes improve (but not get rid of) the tinny voices by running the Low Pass Filter set for 2281. I'm sure others have better ideas because I'm far from an expert at removing noise from audio.
