When selected, a frequency response graphic will appear in the center window.

Typically an impulse is taken with the source on the left side of the stage and the right side of the stage. Each channel L and R is processed with its own unique stereo impulse. So normal stereo reverb, where the input is summed to mono before being processed. No DAW can fix that.Generally, all info related to the reverb selected is displayed in the interface window of SPACES II. If that's not enough for getting good results, sell the microphone and get something better. And it has a 10dB pad switch which you likely want off if you are hearing noise over your voice, at least as long as you don't experience distortion. The microphone has a dedicated side for recording (where the logo is) which you should be singing in (don't just hold it like you feel a microphone should be held: from the description you need to sing into its marked side rather than its top like you'd usually do with a singer's microphone). I've taken a look at the "User manual" of the CAD 37 and they don't even bother supplying fantasy values of frequency range, sensitivity, equivalent noise levels or polar diagrams, instead just talking about "studio quality" and "professional". However, USB microphones are not intended for professional use and are predominantly useless for that, too (how are you going to synchronize several microphones when they all have their own A/D conversion without clock-in/out?). They still can be reasonable quality (and most hand-held recorders use them). Those cannot offer the same S/N ratio as true condenser microphones, particularly not large-diaphragm condensers. Now USB mics are usually electret-condenser capsules. Broadband noise, in contrast, is almost sure to originate from the analog circuitry of your microphone, and it cannot be "weak power" either since USB runs on fixed voltage. You can get various bits of noise from unstable power supply and inverters for step-up DC/DC converters and ground loops. If your characterization of "white noise" is somewhat accurate, you are out of luck.
