Comparisons
I recorded a friend last Saturday. He plays
acoustic guitar and sings. I'd never recorded
acoustic guitar before, so I figured I'd take a shotgun approach to trying to getting it right and save time.
I used a Tascam 2516 console, which was routed to a Tascam MSR-16 (with DBX), a 22-2 (no NR), and into my computer through a Delta 44. In summary: 4 tracks on the MSR-16, 4 on the Delta 44, and 2 mixed "live" to the 22-2. On the MSR-16 I used a special formulation of Emtec LPR 35, and on the 22-2 I used Quantegy 407, both machines at 15 ips. I recorded the Delta 44 at 24-bit, 96.6k. I used two condensers on the guitar, one at the sound hole, the other up above the guitarist's shoulder, angled in such a way to avoid phase cancelation (I checked everything in mono, no phase problems that I could hear). Aimed at the singer's mouth, but a couple feet back, I used a ribbon mic to capture the room and vocals. The last track was direct in from a pickup on his guitar that added a little more bass, but at the same time some more attack. He sang and played at the same time, live to both tape machines and computer. I recorded in this way because I try to be open-minded about how I record, and figured the thing that digital would be able to do best would be record pristinely clean, acoustic instruments. And, like I said, since I'd never recorded this type of music before, I was interested in seeing where it would go.
How anyone feels about the mic placement I used, the mics (which were cheap - Nady and Oktava), and my pre's is irrelevant: each recorder got the same treatment and the exact same take. The signal going into each recorder was strong, with the digital signal centered around -4. I kept the peaks on the tape machines as close to 0 as possible, and they barely went over at all. So, I used a strong, but typical signal into all of the recorders, for the best possible signal to noise on that particular medium.
The Tascam 22-2 had a great sound. A little bassier, but much fuller than all of the other mediums. The only downside, of course, was I have no real control over it unless I master it to another format, where I could fool with EQ, channel mixing, etc. There was barely any audible hiss, but I don't have any noise reduction for this recorder anyway.
The MSR-16 sounded really good, no hiss at all, very full sound. I wish I could have used a recorder more suited for this kind of music, like a TSR-8 or even a 22-4, but no big deal.
The Delta 44 sound OK, but, weak and tinny in comparison to the tape machines. But no hiss, right? He he he.
When I listened back to all of these, they were all "unmixed," with the same settings playing back as they went in. Now, of course I could mix the MSR-16 and Delta 44 tracks and make either of them sound "better," but I haven't yet. I'm open-minded, maybe I could make the Delta 44 end-mix sound better than the MSR-16 mix once I mix it down to computer, but I don't think I could, as I find it much easier to mix with analog. However, I don't doubt that a true engineering professional could take these digital tracks and make his or her end result sound a helluva lot better than the analog mix I could make, even using my cheap equipment. But, by the same token, I feel an analog professional could obtain an even better result than the digital.
I also let the perfomer hear the different takes (or rather, the same take done on different machines) and he agreed that the digital one was the worst. It wasn't that it was bad, it just couldn't hold up to the fullness of the analog versions. There was also not a huge difference between the MSR-16 and 22-2, but I personally liked the 22-2 sound best, probably for the more "raw" sound.
Now, of course my opinion is all well and good for whoever has reached this far down to the end of this post, but there's no way anyone could possibly hear these major differences unless they came to my basement... err, studio... But, I am a believer in the fact that analog tape can soften the blow to digital, and add pleasing effects like watching a film on DVD instead of VHS, rather than dumping right to digital. So, if anyone wanted me to convert these three mediums to MP3 for them to try and compare, I could for you. There might be somewhat of a difference, but the MP3 strips so much out of the life of the recording, that I'm not sure which will sound coming out on top.
If I have a request or two to do this I will, and would follow the same procedure on each take. I would not mix any of them, other than putting it to stereo from 4 tracks, but this would be without changing how the signal went in, just playing back at unity. After having a stereo mix of each, at as strong a digital signal I could put it to, I would normalize each to the same value (probably 95% to try to avoid further MP3 artifacts), then put them all to MP3. Then you all can decide, he he.
