you cannot remove DISTORTION from clipping, so the process above might "get rid of red" but it will not eliminate the sounds created from the track being clipped in the first place

also its pointless to be boosting at 42hz just because its your cars peak when a song might not even have 42hz note in it, find songs with notes around there, then boost them if they arent already clipping

This is what I mean when I said I was boosting around 42hz. I would slow the song down to that frequency, then deamplify it to get rid of the red. After getting rid of the red, I would boost the specific frequency as much as possible while avoiding the red stuff. if it went over 0db, i would deamplify it and call it good. My main purpose was to get the peak note without any red.

Now I'm realizing that I think i'm doing it wrong..

The song could be clipping even though it's not hitting the 0db mark, right? I think I might have just slightly reduced the clipping in the song when I "boosted" it.

Decaf. So do you go through a song and select every single beat one by one or could you take a whole track, highlight it, and boost x frequency? Or do you have to boost every single bass line by itself

o hell no, that would take forever to pick each beat. What I do is find the highest peak of bassline 60hz and under and boost there because every frequency below the chosen boost frequency will get boosted. Not many notice this at all. You can create some havoc real quick though because not all the bass in the song is equal in loudness and bass boost can make that inequality greater. Its a touchy process with a lot of applying effects and undoing until its correct. Every song is different and I never do the same thing to each song, there is no magical step by step process like some people think there is

De-amplify simply lowers the amplitude of the waveform, its still distorted and misshapen, slowing the song will elongate the duration of some unwanted basslines. You should never go past 0dB unless its minute fractions of a second of mids/highs... and you should not be crossing 0dB then de-amplifying. You will create distortion that way.

How I do it:

Open Audacity.

Open The song twice in Audacity.

"Normalize" both of them.

First song: High Pass Filter (whatever frequency: 50 hz, whatever), then EQ and cut everything below whatever (say 50)

Second song: Low Pass Filter (say, 50-60 hz... whatever), EQ and cut everything above whatever (50, 60 ex..)

(you can HP/LP them, EQ them, whatever as many times as you want... you can do it on multiples- Like a Treble track, Mid Track, Bass, Sub-Bass track, etc...)

"Normalize" both of them again.

Then, boost your Bass track or Tracks.

Then play them and make sure you don't have clippage... if you do, lower your levels.

This way though, you can independently adjust your highs/mids/bass. It is tricky to do with some songs and still get the vocals you want. Best way to start though is with a track that is clean to begin with. Once there is clipping- it can't be unclipped. Have fun messing around.

...that's how I waste my time with Audacity anyway.... :D

before i got my hands on decafs songs i did almost the same thing but with three tracks so that i had high mid and low

so how does one locate the peak bass frequency in Audacity, i have been trying to do it but regardless of the song (even if i know for a fact it peaks at 50hz or something) i always end up with 86hz which i know cant possibly be correct.
