Dynamic versus Condenser Mics.

A microphone is a device that captures audio by converting sound waves into an electrical signal. This signal can be amplified as an analog signal or may be converted to a digital signal, which can be processed by a computer or other digital audio device. This forum is for discussing Dynamic, Condenser, USB, Ribbon and Stereo Mic Sets.

@River. I think the 57 and 58 suggest 57dbs of gain. If you are getting a -20db signal using just the H4, you are only 2dbs off of the sweet spot. If you can do a 20 to 30 second test clip for me, I can give you a very educated opinion on whether you should invest in the inline preamp. If you do decide to go that route, the cloud-lifter comes very highly recommended. It has very clean gain. I will send you a PM and give you my Dropbox upload link for the sample. It will send me an email when you upload it. Just record with 3 or 4 seconds of silence and then talk normally.

So word on the street is that the SM57 typically does need extra amp, esp. when using just the voice. I got the sE Dynamite since it promised to do exactly what I wanted: give lots of CLEAN gain. I preferred it over the Cloudlifter for its simplicity -- it attaches right into the end of the mic, so a second cable isn't needed -- and it was a lower price.

The Dynamite is dynamite.

Beforehand I had my Zoom's gain at 100%, getting a muffled signal and lots of room noise. Now the gain can be set to 50% and I get a sparkling clear signal. I could pick up some background traffic but it cleans out of the file nicely; alternatively I'd probably have success with even lower gain.

The sE is great. a boost of 28dbs is fantastic. Just keep in mind that regardless of what mic you use or the AI or pre-amp, you want your input level to hover around a -18dbs. This is equivalent to 0dbs using analog meters. I played both your files in Reaper. I noticed you recorded your last sample in stereo. The ACX prefers mono but they will except either one. The only time stereo will be a problem, is when it comes to file size restrictions.

I also noticed that when you started your second recording, you either bumped your desk or mic and you had a few lip smacks. The lip smacks are common and the more gain you apply, the more pronounced they will become. As always, YOU SOUNDED GREAT!

Yes, I forgot to render to Mono instead of Stereo when exporting that clip. It was also a test recording so I know what extra noise to anticipate next time.

Now that is interesting that you recommend -18. I have heard elsewhere that between -12 and -6 is optimal.

Everything in audio is math. From musical instruments to recording. I play around with the drums and bass when I have a spare min or two. Someone asked me one time, "how do you know what beat to keep"? My reply was "if I can play a 1/4 note that sounds good, then I can also play 2 1/8ths, or 4 1/16ths, or 8 1/32s". As far as the input levels, I simply contacted the tech support for Alesis and Tascam, and asked their advice concerning input levels. These are the companies that I support the two audio interfaces/pre-amps I use. Both told me that their gear is designed to have the lowest noise to signal ratio, with a input of a negative 18dbs. (-18dbs)

Your input levels is a critical factor in proper recording. Your first sample hovered around a -24dbs. Your second recording was dead on around a -18dbs. Now if you want to dig a little deeper into this -18db theory, check out this article written by Massive Mastering. He is very well respected in the Mastering Engineering World, concerning audio and he has a very "NO BS" personality.
