I am sort of a “basshead” by definition lol. Although I very much enjoy sound quality too. I realize the purpose of using normalize and my system is balanced to -5db. I would like to use the normalize feature but it has a fatal problem for me. If I understand how it works exactly then it analyzes the entire frequency spectrum then normalizes the entire song based on the peak max frequency and changes the entire song accordingly. However I would only like it to analyze 15hz to 70hz then adjust the whole song based on that.
Also somewhat related but can I also make another normalize feature that would leave below 70hz alone then adjust everything above that?
I love audacity and I want to learn how to customize it better to my needs
The purpose of the Audacity Normalize effect is to amplify the audio to a specified peak level.
Most audio file formats have an absolute maximum signal level of 0 dB and sound cards have an absolute maximum signal level of 0 dB. Attempting to create a 16 or 24 bit file with a signal level above 0 dB will cut off any audio above 0 dB creating unpleasant distortion. Audacity is able to handle signals above 0 dB if you are using 32 bit float format for the audio track, but playing back anything above 0 dB will be clipped (distorted) by the sound card. The main purpose of the Normalize effect is for ensuring that the audio is at a reasonable level before you export. A “reasonable” level is usually close to 0 dB, but never above 0 dB. Typically I will Normalize to -1 dB for WAV files and -2 dB for MP3 files (MP3s require a bit of head room to prevent clipping).
If you want to adjust the amount of bass, use either the Equalization effect or the Bass Boost effect before Normalizing.
However a lot of songs have low frequency effects that are minimal close to -9db or much lower… My goal is to take the highest level of bass say maybe a 45hz frequency at -9db and amplify it to -5db…
using bass boost will only boost at a certain frequency with a rolloff on either side.
