Microphone Noise Suppression with Studio Quality

post #1 of 5
Thread Starter 
Hello,

I've been wondering, Why can't I use Microphone Noise Suppression using an Onboard Realtek Sound Card (in my case) @ 192000 Hz, But once I reduce the quality to 48000 Hz the Option becomes Available.

Can I somehow use Noise Suppression @ 192000 Hz or do I have to use 48000 Hz in order to have that option available?

When using 192000 Hz - The sound is very clean and good, but it's somewhat weak - Then when I try using Microphone boost, it causes a rather strong static noise which forces me to disable it altogether. Then I'm back to the weak mic volume.

When using 48000 Hz - the Noise Suppression function disable the static noise when using Microphone Boost and the volume is good, But I suppose the quality is reduced.

Help? smile.gif

Thanks.

Likely the noise suppression plugin does not have the ability to accept signals at such a high sample rate - and converting down within/before the plugin would defeat the purpose of using 192khz. Realistically, you should not be recording at 192. The quality difference will be unnoticeable to essentially everyone. Most professionals can't tell the difference with thousands of dollars worth of listening equipment, trained listening, and dedicated tests. I would even go so far as to say that most professional studios (with hundreds of thousands of $ worth of equipment) generally record at 41. If you are recording music use 41, movies 48. Forget 192, it is not worth the larger file size in anything but the most ridiculous and extravagant situations. The quality of the A/D converters in your on-board sound card are limiting your sound FAR more than the difference between those particular sample rates. Don't even get me started about your mic.

What kind of noise are you looking to reduce? Maybe I can help you get rid of the noise rather than processing it - attack the problem at the source.

It's Alright, when I use Acoustic Echo Cancellation and Noise Suppression the sound is pretty clean. I was just wondering whether reducing the sample rate is worth the Microphone Boost & Suppression option. Now after reading your post I will just use a clean, high-volume 48 configuration rather than a weak/high-volumed but noisy, 192 configuration.

Thank you smile.gif +rep

What environment is the mic in? A sound dampened room would reduce noise.

Yeah, naturally.

My room is somewhat noisy because I like having my ceiling fan on at maximum speed and same about my computer fans. As a result, There's always this "Whoosh" sound of fans pushing alot of air in my room. Also, I like having my window open all the way and my street is pretty noisy too, so sometimes trucks and buses cause quite a disturbance.
As a result, I need to use Noise Suppression and Acoustic Echo Cancellation features, and I think I'm going to avoid the Microphone Boost for now as using this option increases the audibility of background noise noticeably - Which I'm trying to prevent smile.gif.

So yeah, Using the options stated above, I get a clean, clear sound and don't have to worry about people complaining about any noise, static or background, while the volume is high enough as it is.
