Changing EQ over time[SOLVED]

Audacity 2.0.3, Win 7 Pro 32-bit

Is there any way to change the EQ over time? In other words, say at 1:00 the EQ is neutral (0 DB); you then want to roll the bass gradually down to -6DB by 1:30, then at 2:00 roll it back up to neutral by 2:30. The reson - to avoid abrupt changes in EQ in sections where the recorded file bass level fluctuates (I don’t want the bass to suddenly cut then suddenly come back). This would be a very handy thing to do! I have never seen an audio editor that can do that, but I certainly haven’t seen them all. Can Audacity do that? If not, does anyone know an audio editor (free or pay) that can do that?


Yes you can do that in Audacity, but it’s a bit fiddly to do.
Give me an idea of how much detail I need to type - how familiar are you with Audacity/audio software/computers?

I’m just starting with audacity, but am very familiar with digital audio editing and production - I have used Sound Forge 6.0 for years (and a few others, but Sound Forge is by far my major experience), as well as programming digital synthesizer sounds and effects. And I am very computer literate. I just didn’t want to spend a lot of time trying to do the impossible. :slight_smile:

It’s late here and I have to be up early tomorrow, so if I don’t give enough detail. please ask.

Basically what you need to do is to make a duplicate track (Select the track then Ctrl+D).
Apply the EQ that you want to the duplicate track (Effect memu > Equalization)
To go from the original track to the EQ’d track smoothly; fade out the original track and fade in the EQ’d track. (Effect > Fade In / Fade Out).
Can you work it out from that?

Hmm, yes, it is a bit “fiddly” as you put it, and for multiple transitions it means putting in some time, but it’s an interesting concept and worth a shot. Yes, I can figure it out from there. Thanks!
