Dies Irae, Live at the Ranger, 3/24/07
3 Songs, 192 kbps, 21 MB
As I mentioned before, we didn't have our usual trusty supply of gear that night, but we came up with enough gear to record a minimalist setup. We ended up with 7 inputs separately tracked to our DAW, recorded with a flat EQ and no real-time processing so we could tweak the tracks during mixdown. As for our microphones, we were forced to go with what we could find or borrow in true guerrilla fashion. For the drum mics we acquired from a local band the surviving pieces of a CAD Pro-7 Mic Kit: a kick & snare mic and two tiny overhead condensers. For the guitar we found an Audix I-5 dynamic mic, and the bass was recorded through a DI box because the bass cabinet had a rattle and we were short a decent bass mic. The vocalist had his own SM58 which topped out our minimalist track list at number 7.
We weren't expecting spectacular results from this borrowed equipment, and well, the raw tracks at the end of the night confirmed our expectations.
First off, lest anyone be misled by the model name of the drum mics, rest assured there's nothing "pro" about those CAD microphones. Tracking drums for Dies Irae should have been a cakewalk-- the drum set was beautifully tuned and the drummer's a solid player, but these microphones couldn't keep up. The CAD kick and snare mics had no usable definition regardless of placement. There was so much excessive bleed between the CAD mics that EQing each to sound reasonable was a real chore, because for example, boosting the snare mic to get that "crack" meant that some other part of the drums would emerge with unnatural emphasis and mess everything up. No amount of EQ to the kick mic could make the "thwack" come out (although the bleeding snare became more apparent and even more awful sounding). Judging from the raw tracks, I'd suspect that both microphones have a frequency response similar to string & can telephone acoustics.To make matters worse, the CAD CM217 overhead microphones proved completely worthless and crumbled under the decibels the drummer delivered that night. Even though the pad switch on the mic was engaged and the mic preamps were purring with plenty of headroom, the CAD overheads delivered audio that sounded like a truck dragging sheet metal down a gravel road. Check it out:
The final word is that this line of CAD mics officially suck and should be avoided for all recording purposes, unless you're absolutely desperate for drum coverage and flat broke (in which case check garage sales and pawn shop dumpsters). If you're at all interested in fidelity in your recording, you won't find it with these cheapie drum mics. (Studio gear elitists can emit a big "duh" here-- hey, we're just clarifyin') There are better alternatives for mic'ing drums on a budget, and these ain't it.
For the guitar, we ended up using an Audix I-5 dynamic microphone, even though we had access to a trusty SM57. At this point, the whole recording was turning out to be a microphone experiment any way, so we decided to check out the Audix mic first-hand. The I-5 has a reputation for having a brighter sound than a 57, and sure enough, the guitar tracks we got were lightbulb bright, and Brillo-Pad harsh. To be fair to the Audix, the guitarist was using a Mesa Boogey dual 12" combo with its settings unchanged from a recent jazz gig, so the rig was already a bit bright, but the I-5 seemed unable to translate any of the beefy end regardless of mic placement, even though the I-5 also has a reputation for a warmer low end. While this microphone might be suitable for other guitar tones, amp/speaker characteristics, or genres of music, using the I-5 on this occasion left our guitar without any warmth in the low-mid end of the spectrum. We wanted Dimebag, and all we got was a nickel.Recording the bass was about a simple as it could get. The bass patched directly into a DI Box and fed parallel signals to his amplifier and our mixing board. Even though the bass was thick and full for the live audience, the signal we received was nothing more than what the instrument pickups delivered. Without the amp and speakers to shape the instrument's sound, the bass was expectedly naked and thin. We knew going into the live recording that in order to get a good bass sound we would either have to re-amp the bass track afterwards, or emulate a bass cabinet with an appropriate emulation plugin.
Here's a snippet of all the raw audio; first the bass, then guitar, drums and vocals:
After inspecting the raw audio, it would be totally forgivable for an audio purist to write off any hope for salvaging this experimental recording; after all, the overheads are massively clipping and the instruments don't sound as good as they did live.
Still, since guerrilla recording is all about doing the best with what you have, CHiTT set out to show that the darkest hour is just before post-processing. In the world of digital audio, nothing is completely lost, and with enough knowledge, the right tools, and a little hocus pocus, you can clean up anything. Here's the same audio snippet after a couple of hours of tweaking in the studio (with all tracks up at once):
In our final installment in this series, we'll cover exactly what we did to fix the tracks to the best of our ability and arrive at a fan-worthy bootleg despite using cheapo microphones.
