Three microphone tests for low-cost audio recording
Here are the three microphone tests I referred to in my earlier post. If you do not see the audio players below, you need up upgrade your Flash player.
The first is the $20 lavalier mic (54 sec.). It’s a bit LOUD, so turn down your volume. (See note at bottom.) I could have fixed this in the editing, but I wanted to show the raw differences in the three mics. Also, you’ll note how you can really hear the water sprinkler in this one. I sat close to the sprinkler just to see how much ambient noise each mic includes.
The one below is the $10 Nady mic (2 min. 14 sec.). This was recorded in the same spot as the lavalier, using the same recorder and the same settings.
The one below is the EV 635, a $100 mic (1 min. 8 sec.).
The WS-200S recorder saves files in the WMA format. I transferred the files to a Windows computer using the recorder’s built-in USB connector. I opened each one in Adobe Audition and cut out a bunch of extraneous mumbling and blather (me talking to myself). Then I exported each one using the same settings for a mono MP3 file at 22.05 kHz. I didn’t perform any adjustments or normalization on any of the files.
For all files, I sat in the same spot outdoors. The files were recorded one after the other, as three separate files.
Note: After digging around in the cryptic menus in the Olympus WS-200S recorder, I found a Mic setting that can be changed from “Hi” to “Low.” Changing it to Low gave me a 100-percent-better result with the cheap lavalier (32 sec.):
