The objective is to lower the noise floor during recording. To achieve this, we aim to record in a quiet environment, minimizing ambient noise. Additionally, it is crucial to properly configure our recording system to prevent any noise from being introduced into the setup.
# Ambient Noise
Ambient noise could refer to the background sounds present in an environment, such as the humming of an air conditioner.

# Pre-Amp Noise
Pre-amplifiers tend to add noise, particularly when you turn the gain potentiometers up to the top 10 percent of their range. It is usually wise to avoid cranking the pre-amp gain that high. Instead, you can use a cloud lifter to add clean gain to the circuit, which helps prevent the introduction of undesirable pre-amp noise.
# Microphone Self Noise
All microphones generate some level of noise. This inherent noise is referred to as self-noise, and details about it can typically be found on the microphone's specification sheet. Here are the self-noise specifications for the Neumann U87.

# Digital System Noise
Bit depth determines the digital noise floor. A 16-bit system has a noise floor of 96 dB, while a 24-bit system achieves a noise floor of 144 dB.
