Paul-L’s de-esser plugin is capable of that, (although it wasn’t designed for the purpose).
It’s a multi-band limiter: you could set a narrow band, say 250-350Hz , then lower the threshold till it just took out the loud ring , (assuming unwanted ring is only 290Hz : no harmonics ).
Are you thinking: “The ringing occurs when the drum is hit hard, so the solution is to cut the ringing frequency when the amplitude is high.”
If so, that probably won’t work.
The ringing may well occur as a consequence of hitting the drum hard, but when the amplitude is high, what you will hear is “BANG”. Any ringing will only be noticeable after the initial transient - when the level has dropped down. “BANGggggggg”
So why not apply EQ one type of EQ to loud songs, and a different EQ to quiet songs?
There are ways to apply EQ only to the “ringing” part of a drum hit, by using side-chained gating, but as Audacity does not currently support side-chain effect, it is complex and tricky to do that in Audacity. Briefly, the approach would be:
Duplicate the track (track 2)
Gate the duplicate track (track 2). The attack time of the gate is quite critical as you will need the gated and non-gated tracks to cross-fade
Duplicate the gated track (track 3)
Invert track 2
Mix tracks 1 and 2 (this gives the “tails” of the beats)
Eq the mixed track to reduce the ringing
Mix the two tracks (the “mixed” track with the track created in step 3)
Sort-of. Each snare hit lasts 190ms, from initial transient to the (meaningful) end of the snare rattle. It’s within that 190ms that the 290Hz ring can be heard… clear as a bell…
I’m also battling the spill from the bass drum (especially low frequencies) bleeding into the snare mic after that 190ms. There’s also high-hat spill there too, and stage noise but a gate set to open and close at threashold slighly louder than the bass drum will also get rid of the high-hats**. That’s 90% of the time and the last 10% is managable to manually edit out the occasional rack tom.
It would be nice if the ring was consistent in the loud songs, but within the same song, within the same verse or chorus, it’s hitting an acoustic threashold and ringing. There’s 90 minutes of music to go through, it’s a bridge too far to finesse the solution beat by beat.
The ring (usually) happens when the force has overcome the internal stiffness of the shell. It takes so much and then gives and rings like a bell. Careful tensioning of the skins can provide stiffness to overcome this (or change the note) but this recording has been made and there’s no going back.
Yes, 290Hz is the annoying frequency - close enough for a mid-D note. There are no noticiable harmonices (580Hz, etc) that can be heard above the rest of the drum noise (the much sought-after snare rattle that’s difficult to not truncate with gates).
** why get rid of the bass drum sound in the snare mic? What the snare mic picked up sounds disgusting and is detrimental when adding it to the now-tidy bass drum channel. I’ve also found the mic under the snare is unusable - it’s just all rattle, set off by the bass amp only a metre away - so all my snare sound will be from this mic and whatever was picked up by the overheads (also full of the stage noise, vocals, bass, guitar, crowd noise). At least I was able to clean up the tom mics with 98% only toms in those channels.
I know it’s too late, but what’s the microphone and can you hear the damage in real life?
Drums are killer hard to mic. You may be listening to the element inside the microphone overloading. The SM57 worked so well with drums because it’s almost completely impossible to overload it. Was this a condenser? I wonder if that’s what it sounds like when the diaphragm hits.
well, the overhead mics can hear the ring, although not anywhere near as obvious as the close mic’d Shure Beta 56A.
That’s why I’m trying to do as much as I can on indivudual channels - there’s spill all over the place that I’m trying wrest some control over. A bit of crap here in this channel, plus a bit more in another channel… and it ends up sounding like a big bucket of poo…
A sizable chunk of this thread seems to concentrate on possible prevention. Live recording of drums especially on a venue’s stage is fraught with compromises based as much on room/stage acoustics and time available to finesse the setup as equipment used… a conversation perhaps best had in recording forums.
This thread was started, however, to deal with post-production. Correcting or masking problems already captured in the recording.
As it’s turned out, the “under-snare” mic recording is unusable - it’s just all snare rattle, even when not being played (the bass amp was only a metre away) and the overheard drum mics sound awful - full of vocal foldback, guitar and electric bass. I’ve had som success gating the toms (and manually editing the 2% it couldn’t remove) but while the gated bass drum got rid of stage spill (foldback, guitar, bass as well as most drums) it sounds awfull and compression and EQ aren’t saving it.
Hindsight is always 20-20. I’m just trying to get rid of as much rough edges as possible to create something that’s listenable.
