I use for my voice over in my video montages a podcast from Rode, in shockmound and ofcourse audacity for register the voice. When I play that again the sound is “hollow” like I speek in a metal pipe. The room where i work is small.
Is there a filter or other system in audacity to make my voice over bether ?
If you conform to the modern idea that all your surfaces need to be polished oak and you subscribe to the clean, spare look, then recording voice is going to be an adventure. We’re currently struggling with a friend on the US east coast who volunteered to do promotional announcements in one of those rooms. It was pretty, but it sounded awful. We’re fitting her with a proper microphone, but it’s still only going to help a bit. The problem is not going to vanish.
This clip will always sound echoey. There is no filter for room echoes.
The left-brain analysis tells us that room echoes are your own voice arriving at the microphone later and later than the original speech by bouncing from the walls. So basically, you’re asking the software to filter you out of yourself. Rough to do.
Can you take the equipment outside? Just for a test if you have a quiet neighborhood, test the system exactly as you have it, but without the room. Most of the presentation sounds OK, but you have that constricting echo sound and I think that’s what’s killing you.
I’ve been known to build a studio out of furniture moving blankets to get away from this effect.
There is a tool in audacity that allows one to see the reverberation. In the Analyze menu pick plot spectrum. Use the autocorrelation function. The peaks occur at the reverberation frequencies of which there are several sets probably corresponding to the walls and ceiling in the room as reflectors. Trebor’s procedure can be seen to greatly reduce the reverb as the ear also agrees with.
The second recording does not show as great a reduction in reverb as the original poster’s recording does with Trebor’s settings. The room for this recording may not have parallel walls or for some other reason show such well defined peaks as the original poster’s room. It may also be that much of the spectral content of the woman speaker’s voice is so much higher than the reverberation frequency that the reverberation is less pronounced in the autocorrelation.
