How to minimize mic noise, new sound card ? Or do I get a preamp? or both?

post #1 of 8
Thread Starter 
Greetings,

I've recently been tasked with an audio project that requires some vocal recording.

I have a Asus Z68 chipset mobo
Using mic in on rear I/O plate
WIndows 7 x64
Ableton Live 8
Sennheiser wireless mic (G100 W3).


In Windows I've turned up the sensitivity of the Mic In to about 40 (out of 100). There is an audible hum or hissing sound.

Now I know this is probably due to the interference from the Motherboard's on board audio, as I've experienced this sound before long long time ago..

Do you sound guys think any of the following scenarios will help.. and how much it would help?

1. Buy a standard XLR wired mic and a pre-amp -> USB
2. Buy a new soundcard and move it away from the video card (continue using the sennheiser wireless mics)
3. Buy a new soundcard and move it away from the video card ( AND buy an XLR wired mic and pre-amp)
4. It's something else in the case, and none of these might work

I also utilized a macbook air for on the go.. and since it doesn't have a mic-in (it's built in mic is quite good so I've stopped using the windows machine, lower latency and no discernable hiss) .

Many thanks for any/all constructive suggestions.

That is a toughy, I would bet my money on voltage leakage/interference from Motherboard.

The only easy solution I know of is get a soundcard, preferably with it's own power source, and use all the other equipment. Least changing you have to deal with.

I don't know how Creative are these days, but in their past their drivers were atrocious. I think Azalea and Asus are pretty decent medium budget cards that would work.

Yea, there would be a lot to test, and I don't generally have the know how and time to isolate it all down to the exact source of the hiss..

You're talking about external soundcards then?

Would a DAC (Digital Analog Convertor) be the same thing essentially? Does converting the analog signal outside the box prevent this distortion?
Is a DAC different from a Pre-Amp ?

A DAC is a one-way converter from digital to analogue audio. You would need an audio interface, which has both inputs and outputs, and acts and both a DAC, ADC, and preamp.

What's the mic you're using now? Can you be a little more specific about the project and what kind of audio quality you need out of this, is it a voice over, interview, etc.

Thank you for the clarification on DAC vs PreAmp vs ADC

I'm recording a singer's vocals which will be then mixed with a music track.. I may also do voice overs in the future.

Well an example budget setup for studio vocal recording might be a Focusrite 2i2 ($100) and MXL V67G ($77), plus a mic stand and mount, XLR cable (monoprice makes good ones), and a pop filter. Probably $225-250 all in.

There are other things you need to try as well.

First, make sure your input devices are connected to the rear inputs and NOT a USB hub or front panel. Sometimes those can cause noise issues.

Second, make sure your interconnects such as audio input and USB cables have "Ferrite core" on them. What that does is helps eliminate any noise problems that may be introduced along the path. I know it cleared up my headset.

Third, try an actual "Ground Loop Isolator" for 3.5mm applications. You just plug in your audio cable to it and then it plugs into your motherboard.

All three of these makes good sense to use in order to have the best possible sound and help eliminate any noise problems or other possible concerns.

Hope that helps some.

As stated in my original post, I'm using the rear I/O port.

I'll see how much that isolator costs, and give it a try thank you.
