This is the same microphone placement that makes professional wireless lapel microphones sound so good. By doing this I get the built in (omnidirectional) microphone very close to the audio source (person’s mouth) which greatly improves audio quality.
I use the voice recording function of this MP3 player to capture presentation audio by placing (actually cliping) the device on the shirt of the person doing the presenting.
#LEVELATOR FOR MP3 PLUS#
The SanDisk Sansa Clip Plus MP3 player has been very useful to me for capturing mobile audio and I’ve decided to write about it so others know about this useful little device. Once all the editing it done, the audio is then rendered (or produced) into MP3 format.īelow is a video I made of the production process using Audacity & the Levelator (the audio used was recorded using the Olympus LS-10 setup): Once I am done with the recording, I take the WAV file from either recorder, run the file through the Levelator, and edit them using Audacity (remove parts I don’t want). On the Marantz PMD661, each channel has it’s own gain and can be adjusted independently depending on the person’s speaking volume. One tip on using the devices, the Olympus LS-10 can be setup to use Auto-Gain or Fixed-Gain, the gain applies to BOTH left and right channels at the same time, there is no individual gain for each channel. With hand-held microphones, moving of the hand on the surface of the mic can cause audio noise to be picked up by the recorder. I prefer to use the lavalier/lapel microphones when I can because it allows me to place the microphone at a consistent distance from the mouth of the person talking and there is little chance for handling noise. One of the more important points about recording interviews is microphone placement. It’s made up of a Marantz PMD661 digital audio recorder and paired with a couple Shure Beta58A microphones (as pictured) or a couple Shure PGX wireless lavalier/lapel microphones (these require AC power nearby). The second setup is also for field recording that gives me more options to either plug into an existing audio mixer, or use higher quality phantom powered wired or wireless microphones. Click on the image to see a larger version. This comprises primarily of a Olympus LS-10 digital audio recorder, 2 lavalier/lapel wired microphones with 1/8 mono connectors, and a Y connector which connects each mono connector to the right or left stereo input on the LS-10.
#LEVELATOR FOR MP3 PORTABLE#
The first setup is for ultra-light portable field recording without any power nearby or audio mixer to plug into. When I record audio interviews, I usually choose between 2 hardware setups depending on the situation.
