want hear / extract clear voice from recording of lecture/discussion

[anandcoral]

I have a recording of lecture/discussion. It has some noise of the hall room.
Now the voice are not clear. I want to hear / extract clear voice.

Googling gave me links of removing the voice, but I want the reverse.
Also gave me paid software links which claim to do it.

Need Advise ?

Adobe Audition.  But it's an adobe product, so you pay for the privilege.

If you want free, there's Audacity.

Free means in this case a lot more work, and a lot worse (IMO) interface.

There are other options out there (Sound Forge Pro, and GoldWave for starters.), so not sure why you didn't find anything.

I use GoldWave myself, but more out of familiarity as I've been using it for over 10 years for a one-time payment of $45 - I think closer to 12 years.  It's good software.

UNVEIL from zynaptiq..it's a bit costly, but is one of the very best at doing what you want to do.

If the noise that you don't want is pretty constant, and if there is a short interval/length of soundtrack where the speaker is NOT speaking, then you may be able to use Audacity to remove the noise.
Simply sample that interval of noise and subtract/remove it from the whole file
It works very well, and can even remove things like tape hiss or hum from a cassette recording - which is something I have used quite a lot, when digitising audio cassette tapes.

Thanks all for the advise.

I will try them and revert my story

This sort of programmes are disgusting for me.
I usually record all during my work.
I use audacity.  And that is enough.
If you "really" need clean the audio see the movie "The conversation" (1974) with Gene Hackman.
If you try Adobe audition or anyone similar usually you will abandon. There is a lot of "Knowledge curve".

Retouching images exists some automated measures but in audio is not so easy. The same for video (there is a program from Sony)

I usually prefer hear with attention two or three times the audio....


That's my reality

Ejem.... One thing I would like to get is this :

Obtain a written report from a conversation with two or more voices....
