There are enough audio software developers with flagship EQs that you would be ill-advised to do an internet search for "software EQ", lest your browser give you side-eye. We sometimes forget that with all the third-party options, most DAW designers include audio processing essentials with their software - and more often than not, the in-box tools will serve you just as well as any other. Such is the case with EQ8 (which you have to at least have the standard version of Ableton Live to get - sorry, Intro users).
As you would expect, it is an eight band equalizer. Each band has a series of parametric filter options - 48 or 12dB low pass, low shelf, bell curve, notch, high shelf, and 48 or 12dB high pass. You can turn each band on or off (it's recommended to only turn on the ones you need to save CPU, but this device is generally not a CPU hog - admittedly, I have never used it in oversampling mode, though). Audio signals can be processed in stereo, left/right or mid/side modes, and the frequency spectrum of the channel's output is displayed in the background as you work (which, even though you have to learn to use your ears when mixing, is still helpful for swift low pass/high pass work).
Rather than go into more detail, I strongly advise you to look up tips and tricks on using EQ8 and find out more about all the capabilities of this device. And remember...you can configure default templates in Ableton, so why not create one with an EQ8 on every channel?
