Condenser Mic Recording Issues On Win 10 With Audacity


I bought a new Condenser Mic a few days back. Tried to record a voice-over using Audacity on Windows 10 but the sound quality is extremely poor. Someone suggested me that I should order a phantom power supply. I did that too but the audio quality was still not that great. I hear hissing sounds in the recordings.

I tried to switch OS. Tried to record on my Mac and some other PC with Windows 7. Results were far better. I think it has something to do with Windows 10 only.

Am I the only one facing this issue?

Which condenser mic and how is it connected? A condenser microphone without phantom power (or batteries) doesn’t get noisy. It stops working. One problem with condenser microphones can be you’re recording your voice on the laptop built-in microphone by accident. That will sound funny and be low volume and noisy.


It’s from an Indian brand called “Wright Sense”. Mic is connected through USB sound card. I’ve already disabled laptop’s internal mic to avoid confusions.

Without details on the microphone and the USB Soundcard, there’s not a whole lot we can do.

There are condenser microphones rated to run from the +5 volts on a USB soundcard, but the makers insist in the instructions that you only get full quality with a “real” phantom power (+48 volt) supply. Further, if the microphone has a three-pin XLR connection…

…then something somewhere has to receive that connection and convert it to digital.

A straight USB soundcard isn’t going to do it.

It is possible to force the microphone to work without any of those tricks, but it will sound like you are forcing it to work. It will record with high distortion, low volume and likely to overload and damage the blue waves at any time.


Is this it?

If so, then it is probably a re-badged BM-800, which get very mixed reviews.

There’s another point of comparison.

Technically, the microphone on the side of your laptop is a “Condenser Microphone.” It’s an electret condenser type which usually produces reasonable sound way out of proportion to its size, but nobody would call it “professional studio.”


Noise is the biggest problem for everybody… And, once you get the electrical noise under control acoustic noise usually becomes an issue (if you’re trying to make professional-quality recordings). The biggest advantage pro studios have is soundproofing.

Does the hiss remain when you un-plug the mic?

“Pure hiss” (white noise) usually comes from the preamp in the soundcard/interface. All preamps generate some noise, but a better one will be quieter.

Condenser mics also have a “head amp” inside, and it generates noise. So again, better mics will be better. Dynamic mics (like the famous Shure SM57/58) don’t have any electronics so they don’t require power and they don’t generate electronic noise. (That doesn’t mean dynamic mics are “better”… Most pro studio recording is done with condenser mics.)

If the sound seems to have a high-pitchpitch, or multiple frequencies/pitches, (Koz calls it “flying mosquito noise”), that noise is usually getting into the analog electronics through the computer’s power supply. It’s a common problem with USB mics and USB-powered audio interfaces. Some computers may be better than others and some interfaces/soundcards are more immune than others. Or, an interface with it’s own plug-in power supply should be better.

There is always some noise, but you can get a better signal-to-noise ratio by getting a good strong signal into the mic. i.e. Speaking/singing with a strong voice, close to the mic.

Most “studio condenser” mics are directional side-address mics. Check your owner’s manual or specs and if that’s what you have, make sure you are speaking/singing into the front side, not the back side or the end.

It’s from an Indian brand called “Wright Sense”.

I don’t know anything about that mic, but most of the “cheap condenser mics” are actually electret condensers modified to work with 48V phantom power and a balanced XLR connection. Sometimes they will work with 5V from a soundcard.

Mic is connected through USB sound card.

Stage & studio mics use a balanced low-impedance XLR connection and are not compatible with a regular soundcard. (And as you know, studio condensers require phantom power.) Sometimes you can get a pro stage/studio mic to work with a regular consume soundcard but it’s the wrong interface and you usually don’t get good results.

And, regular soundcards often have noisy preamps.
