    Here's an interesting one-

    I see lots of stuff on how to make a DI acoustic sound more real, but how would I make a mic'd acoustic sound like it was recorded through a DI?

    Live, or recorded?

    So I have a recording of an acoustic guitar, the recording was mic'd in a studio, and we're trying to make it sound like it was recorded on stage with a DI

    I'd start by sucking out a lot of the bottom end below about 160Hz, and give it a huge "piezo quack" boost about 4KHz.

    Exactly. What I was going to say. DI usually sounds bright and narrow, and articulate. Some well-placed compression might give you that "squashed" sound too. Plus maybe play with a noise gate to see if you can eliminate any reverb.

    Cut the low end, add lots of high end and high mids, crank it till it's in the red.

    You could get a di box and plug it in to that? ;)

    I was hoping to hear why anyone would want to do that.

    Fake "live" album?

    I just recorded some tracks with a Sony condenser clipped to the sound hole, a Neumann M149 at the 12 fret and a Fishman DI off the guitar. The DI track is very midrange focused with less sparkle and little bottom. Hope that helps.

    I’ve worked on some mixes of live recordings where we’ve attempted to match a sound in the studio to fix live fluffed notes etc.

    Sometimes we’d overdub more parts to improve overall impact, but particularly acoustic instruments which suffer the most in live setting.

    I hate to disagree with some suggestions.... but it's the low mids (the body of the tone) you want to cut, not the low end itself. This should be a gentle cut (about 3db) in the 400hz range with a 1.5 - 2 octave Q. The actual low end you can HPF as required to sit in the mix properly.

    Next add the piezo quack (4k)... a little goes a long way. Then compress it fairly aggressively. I'd set the ratio to 4:1 then lower the threshold until you can clearly "hear" the compression. There is nothing transparent about the compression of a piezo ;).

    I don't know any way to remove the percussive pick sound the mic would have caught.... Piezo's can't capture that tone so if it's there that is a dead giveaway it's a mic rather than a pickup.

    Exactly this! We recorded a song a while back and we're doing a "fake live mix" for fun for a little movie we're making.

    I like this. Maybe the cut below 400Hz will already take care of this, but there's also a "boxy" element that may need to be added, which could be a small med-Q boost around 400-600 or so. Then there's a "grainy" or "brittle" texture, which could probably be added just by slightly overdriving something in the chain. Wouldn't take much to do it.

    Perhaps we need to work our way backwards from he usual "How do I make my DI acoustic guitar sound more life-like."

    The first step for this in my live sound days was to compress the he!! out of the piezo output. There were usually two acoustic guitars, so I EQ'd them to where they had their own "space" in the frequency spectrum.

    So... Maybe use an expander and EQ to get that tinny ice-picky sound back. Maybe add some humm and some high end sizzle while you are at it?

    Less work to just grab a guitar with a piezo and record another track. It's not like you need to treat the room or anything. Just sayin'.

    The key to life is to let laziness work for you.

    I would totally just record a new guitar track through a piezo, but I'm currently stuck without an acoustic guitar, just a mic, bass, and my laptop right now, so I'm remixing old stuff for fun until I have access to all my toys/gear again.

    Just another thought, if you can lay down some DI guitar on another track you have something to easily A/B while you fiddle.

    When messing with EQ to target the right range, according to the musical register remember, dial out the +\- all the way, and sweep through the frequency until you find the right spot. If you have a ‘bell’ adjustment you can control the range of the effect and then change +\- to the right level.

    This works well for lower frequency but for mid/highs you might want to be more conservative with the gain as they are the frequencies that make you deaf! :confused:

    Fingers rather than a pick?
