How do I get rid of recording noise?

Thread Starter 

My Gamma1 is dead silent. My Little Dot MKIII is silent with normal listening levels. But with some recording there is quite a hefty noise floor. I have a pair of HF-2's. 

Is it possible for my to get rid of the recording's noise floor? If I were to get higher impedance headphones would it disappear? What can I do?

You can do one of two things to remove a recordings noise...

 

1) EQ it out

 

or

 

2) Use a variety of noise removal software/hardware.

 

Which one to use depends on the nature of the noise and the results that can be obtained. It is usually better to try to EQ it out by using a notch filter but you usually have to surgically apply such a procedure. Noise removal software can easily be overdone and I generally would not recommend using it unless you have a very revealing and accurate system and a high grade noise removal system.

tube amps have more input circuit noise, with higher sensitivity, low Z cans it may be audible, listening at low volume settings is worse - use the lowest amp gain setting

 

if that's still so loud you have to turn the volume down then a output "hiss buster" attenuator resistor divider could help - although usually only needed with iem

 

some recordings also were just recorded with audible noise - its not readily removable

Sometimes it's as easy as attenuating the highest frequencies in a program, but other times the noise isn't just a real high frequency.  For that, you can use a noise remover that will sample the noise and attempt to remove it throughout the recording, but that's usually less than ideal, as you'll lose a lot of the fidelity in the song.
