Threshold Noise Floor Compressor

This is mainly useful when compressing speech to prevent the gain increasing during pauses and so over amplifying the background noise.

Threshold noise floor compressor. In short noise floor is generally the background noise you detect in a recording file. When it comes to noise floor keep always this in mind the lower your noise floor the better. The noise floor feature behaves as an expander below the noise floor s threshold. Although post construction sound treatment is possible it is also expensive.

Something around 50db is sufficient but may vary depending on how loud the recording environment was. Relative amount of compression compared to the threshold. The level above which compression is applied to the audio. The ratio of the expansion is equal to the compression ratio employed.

The compressor adjusts the gain on audio below this background level so as to prevent it being unduly amplified in processing. Some best practices if followed during design and installation. In the image above this range is indicated by the dashed purple lines. Sounds under the noise floor limit are considered background and are not amplified.

The range of the expansion is equal to the amount of make up gain employed. Unfortunately sound levels are often neglected during the procurement process. Set the threshold to this db. It is amplified by the reflective surfaces in the facility.

That noise is usually best detected when there is no other audio signal going along with it. What is noise floor. Draw a graph in your head.
