There can be quite a lot of difference in the frequency response of different lavs, and placement is quite critical for the sound, so a "standard fix EQ" is not possible I'm afraid.
Good places to start are:
- low cut about 90-100Hz to get rid of useless cr@p;
- as Phil said, chest resonance can be responsible for a lot of problems. The frequencies will depend on placement of the mic, on whether the speaker is male or female, and on the size of the chest (no jokes please
). Generally, chest resonance will be somewhere between 300 and 650 Hz, depending on the above. Try playing with a gentle dip filter in that f range to see where you get the best result.
- if the lav is hidden under a thick layer of clothes: try a slight boost in the (mid)highs, around 2 kHz (for intelligibility) and up (for brilliance). This one very much depends on the frequency response pattern of the lav used - most already push these frequencies, so it's a question of trial and error.....
Not EQ, but I find the following very effective for making lav sound sound less "lavvy"
- Edit! Get rid of plops, pops, clothes rustle, rubbing the mic...
- Edit! get rid of heavy breathing (
) due to mouth being closer to mic, and of unwanted mouth sounds (editing or NR). This helps to "pull the sound away from the mic".
- always add room acoustics (and I usually do that in mono) - even perfectly eq-d lav sound sounds unnatural due to being so close and dry. Doesn't even have to be much, just put some life into it.
- add a bit of movement (Foley, or nicked from elsewhere in the recording) - imagine what a boom would have heard had it been there, and try to emulate that. Like with the reverb, don't go OTT.... ;o)
