hey there guys, sorry to bother you all but i just got my blue spark digital usb mic today. I noticed im getting this hum sound and when i touch it, it goes away which is kind of annoying but if i keep messing around with its position it stops, but most of all is there a way i can fix this background hiss thats there even when the mic is muted? i know i can do noise removal but it doesn’t remove it fully and lowers the quality a bit. iv been googling for hours and i cant find out what to do 
iv attached a sample of the hiss which is the same wither the mic is muted or not
No, we need an example of the hiss as compared with your voice. I get a -60 or so noise which is OK, but not if your voice is very low.
The hum thing can be a problem with the USB connections to your computer. Do you have more than one USB connection and does it do it with all of them? Sometimes you can locate the source of the hum, like turning your desk lamp off or moving away from your monitor. Can you plug your computer in to the wall backwards? Try that. My Mac can do that and it can help with noisy connections.
You can also put Audacity into monitor mode (right-click on the red recording meters > Start Monitoring) while listening with headphones. Move the microphone around and see if it gets worse as you do.
My microphone gets really hummy when it put it next to the external backup hard drives. I have a USB headset that will always hum if I don’t touch the computer at the same time.

the hum seems to be fine now, i disconnected everything but the hiss was the same, think you ment about the humming but i checked it anyways, heres me talking with the hiss etc 
tysm for reading btw koz
Microphones don’t hiss. Electret and condenser microphones are capacitors and rock band microphones like SM57 and SM58 are inductors. Reactive components (inductors and capacitors) we are told in our electronics courses do not create noise. However, all of those microphones produce stupid-small sound signals, so they have to be boosted to be useful.
Boosters or Amplifiers do have noise. When you mute a microphone, you can’t just interrupt the digital bitstream. That will drive the rest of the digital system crazy — that’s an error condition. So you should do it while the show is still in analog-land, before the analog to digital converter in the USB microphone.
One way to do that is interrupt the sound even before the microphone preamplifier, the MicPre. If you do that, the show will drop dead, but not the MicPre noise. ffffffffff.
An advantage of USB microphones is their convenience. Everything is built into the microphone. Plug and go. The problem is everything is built into the microphone including the MicPre. With a rock band microphone, the MicPre is in the mixer and if you have a noisy one, you can change it without buying a new microphone.
Thanks for your revised sound clip. You’re too low (attached). We tell people that perfect levels are when your peaks bump up to about -6 on the soundmeters, 0.5 on the timeline.

Yours are smaller than that which means the difference between your voice and the natural microphone noise is too small.
The sound clip has your voice popping like you’re too close, so the microphone sensitivity is too low. I didn’t see a volume control knob like some microphones have. Some microphones can be tuned or adjusted with a software package or driver, usually from the manufacturer. You should search for that.

Focus mode lets you switch to an upfront sound with added presence that adds intelligibility to vocals
OK, so this thing has “Modes” which probably means there’s software somewhere.

Plug in backwards? What is this craziness?
Many Mac power supplies do not have polarized wall plugs. They will plug in either direction and sometimes that can help when you have a microphone or other sound problem. Some PCs work that way, too.
Koz
Attached. There is no big prong and little prong or grounding prong. Some of the larger power supplies work that way, too.
Koz
Ah, got it, thanks. My PC power supply is like that too. Never thought about the way I plug it in having any impact at all on anything. Learn something new every day.
The power coming out of the wall is not symmetrical. There’s a hot side and a cold or return side. If there is any unbalance at all in the power supply, it may very gently suggest that the protective shields on your microphone are electrically “hot.” It doesn’t take much unbalance. Microphone signals are .0003 volts and they have all the massive crushing power of butterfly wings.
This gives you oddball effects like touching the computer or the microphone body causing hum level changes.
This is master class stuff. Solving one of these got me my first LGS* award.
