My secret audacity recipe for great audio compressors 50.
Change noise floor in audacity.
Adobe audition has its fantastic multiband compressor but did you know you can get fantastic audio compression from a free plugin to audacity.
Step 2 reduce the noise.
Then i selected the silent parts of an audio sample that i sent you guys that had a bad noise floor problem and that number is also 12.
Examining repeated blocks of the same noise will not change the statistics.
Artifacts can happen if the noise floor is higher than was estimated.
Noise floor 40db.
Try to keep it between 15 to 18 db.
The benefit of look ahead is that sudden peaks do not pass through the effect before the gain has had time to change.
Try these settings to play around with.
Use a limiter to keep your db range locked in.
Under the effect tab you will find noise reduction command under the drop menu.
Click get noise profile this audacity feature will determine the type of noise in your audio.
The further left you move the threshold bar the more background noise you hear.
I m missing something here.
Attack time 1 5 to 1 9 secs.
There s a window below that get noise profile button i selected a silent section of a published audio book and the noise reduction db is 12.
Release time 10 12 secs.
Threshold 15 db to 18db.
The level above which compression is applied to the audio.
It will eliminate the noise while at the same time maintaining the audio integrity.
Occasionally my noise floor will be perfect just below 60 and i will get a full pass on the test but i m recording in the exact same room with the exact same settings as my too low tests so i don t know why there is a discrepancy.
Click noise reduction tab.
Is there any way to increase the volume of my noise floor through audacity to exactly 60 db.
To optimise the performance of audacity s noise reduction it is best to use a noise sample near the beginning of the tape rather than the end.
