Audacity - Audio Editor - muffled voices

Our resident VAR-meister (weightlifter) mentioned Audacity audio editor in a thread on this forum.
I tried it, but I'm inexperienced & couldn't find a way to make muffled voices clearer.

If anyone here has used it; please do me a favour.
I've uploaded a short sound-file (to practice on) see:
<A href="http://www.painting-effects.co.uk/audacity/original.mp3">original.mp3</A> or <A href="http://www.painting-effects.co.uk/audacity/original.wav">original.wav</A>

Please explain how to un-muffle the voices and, if you have time, please show me what can be achieved by tweaking either of the above sound-files.

Thanks in advance

Re: Audacity - Audio Editor - muffled voices

When i did paranormal investigating we had limited success using audacity. The most effect thing was loud vplume, a dark room with eyes closed, and headphones listening over and over.

Try playing around with the high pass and low pass filters.

Have a look at this. How to Restore Audio Quality with Sound Forge – The Digital FAQ – Media Guides & Services

Re: Audacity - Audio Editor - muffled voices

Thanks guys.


awake1 I tried doing what you said, but I'm worried that I'm hearing what I want/expect to hear, rather than what's really there.
If you have time; please have a listen yourself & tell me what you hear.

BjornFree I've had a quick try (about 20 minutes) but I'm getting nowhere.
Should I switch to using Sound Forge? Would that do the trick do you think?

weightlifter Can you help?


Thanks again.

Can't hurt your chances, normalize the audio before trying out the filters Sound Forge has a lot of them, make a separate copy of the original. I would also seek out the help of a professional sound engineer.

The solution is never tell anyone what you think you hear. Let them listen and compare. If they match up chances are that's what you heard. If not, it might just be bad audio.

Re: Audacity - Audio Editor - muffled voices

One method i used.
1). Get clear sampleof voice and find its mhz
2). Equalize that frequency up

Ive deleloped an ear for it. I get about 2x what RDMU gets and he married her.

IF you wish i do VAR work with transcripts. You would be my 4th person. Only rdmu has partially released me from confidentiality. I dont publish the details. He simply released me to indicate i have the infamous house VAR.

If not. Its an offer not acommand. I have a special email i receive mp3 s on.

Of course it must be english.

Oh im at work atm on an itard. Typing is slow.

Re: Audacity - Audio Editor - muffled voices

Keep getting pulled away.

Understand. There are MANY different methods i se depending on what is going on.

Sometimes i boost elements. Sometimes i reduce elements.

Re: Audacity - Audio Editor - muffled voices

The most effective way i've gone about it is to up the treble on a bassy recording and listen over and over again to the same small section, moving a sentence at a time. Loop it till you have a good idea what it is, and then move on to the next.

If you listen to an entire clip over and over in large chunks you're wasting time.

And some audio clips are just too far gone to know what's going on.

Since you asked, I PMed you what I think is on that clip.

Re: Audacity - Audio Editor - muffled voices

I have used audacity but sometimes to catch what is being said it helps to slow the sound down this facility is available via windows media player. There are lots of other sound manipulating programs and apps out there but without a teacher it is a steep learning curve. A really good set of headphones is a huge plus to produce as sharp a clarity as possible.

Re: Audacity - Audio Editor - muffled voices

For this clip i used windows media player and droped the bass/upped the treble. I then repeated each sentence moving through the clip. Its REALLY poor quality though.

Re: Audacity - Audio Editor - muffled voices

ON A SONY ICDPX312 I can get whispers at 40 feet. 44k bit rate.

Others not as good. At least of those ive heard.

Bit rate drastically affects how much i can manipulate the source. Usually i will do two to five affects to a clip if its difficult.

Odd truth. Whispers are much clearer and less " muddy" as i call it.
