Increase intelligibility and performance of microphone input and stereo speaker output with patented noise reduction technology enhancing your digital audio applications.

Your microphone will perform only as good as the sound card or integrated audio system that it is attached to. Most laptops and PCs today have audio systems built in and it is often placed close to noisy components like the power supply or high frequency processors. In addition, PC’s may be used in high noise level environments which can affect the performance of applications, such as those that use speech input.

  1. Brian Stokes

    This is actually a two-fer: You get an effective piece of hardware (the USB portal) and some sophisticated software that lets you get some helpful microphone adjustments to cope with large rooms or a noisy setting.For example, you can adjust the mike boost and see the levels graphically outside of whatever is doing the recording.Highly recommend.

    I’m so thrilled to have this setup that allows me to have the Zoom meeting feed right into my court reporting software. It doesn’t pick up any ambient noise, they hear me perfectly AND it records me, too! Once Sound Professionals logged on and adjusted all my settings, it was perfect. Love it!

    OMG … I have been struggling with my audio for a LOOOONG time.  I ordered two new Andrea soundcards.  Still had a few things that I didn’t have configured quite right so I scheduled a service call.   Joe got on a service call with me and I am GOOD TO GO in 6 minutes.  He is AWESOME!   And not only did he fix what I was needing, as he configured what I had asked him to do, he peeked around and saw other things that he felt could be optimized.  He spent a few minutes spiffing stuff up, got it all shiny, and then saved screenshots for me and put them on my desktop for my later use.  It is SOOOOOOO REFRESHING to find a company who’s tech support REALLY knows their “schtuff” and isn’t just reading off a cue card!!!!  I reached out and I am 100% ready to go.  The customer service is unparalleled in responsiveness.

    THANK YOU, CHRIS and Sound Professionals, for always exceeding my expectations! Your company is amazing!

    Love this mike. It makes all the difference. You can attach more mikes to it for speaker specific audio. It has a boost feature which gives you crisp audio. I’ve ordered these specific high gain usb mikes as soon as they very available and nothing can change my mind. I never have a fading issue. This high gain mike delivers superior audio.

    Once you use this sound card with a good mic from SP, you will never use anything else. Great sound quality, and great customer support.

    I am so grateful for Sound Professionals, and the help I’ve received from Chris. I had already been using a USB mic from them, but made the leap to this sound card and wow – what a difference it makes. Chris is very prompt and knowledgeable, always willing to answer any questions I’ve had as I get used to my new setup. Thanks so much, Chris, and Sound Professionals!
