I finally had a bit of free time this afternoon so made a quick indoor mic test with the mics I have on hand...
I recorded this in an 8 story office tower on a Saturday so I would be the only person on the floor.
I purposely chose to use the Tascam DR-40 recorder to supply 48v phantom power to the mics and to record the audio, because I wanted an example of using low cost gear to record sound.
My voice is fairly monotone, so if a mic can make me sound ok, it can be used to record just about anybody.
The Tascam DR-40 recording level was set to 50, which is on the low side ( I was peaking around -20 dB ), but I wanted to avoid noise from the DR-40 pre-amps.
After I finished recording, I brought the WAV files into Sony Sound Forge for a little bit of audio processing...
1- I dropped the un-used track, converting the 48 kHz 24-bit stereo recordings to 48 kHz 24-bit mono.
2- I increased the audio volume by about 14 - 17 dB, to even out the levels of the different mics and to make the finished audio loud enough for effective playback. If I had used my Sound Devices mixer I would have done this while recording. ( I know the DR-40 recorder mic pre-amps are noisy when pushed, so I prefer to keep the level a bit low and adjust in post )
3- I used -12 dB paragraphic EQ at 800 Hz to improve the tone of my voice. ( I do this with most of my dialog audio, though I vary the frequency and the amount of EQ used )
4- The room I was recording in was fairly noisy from the buildings air-circulation fans and the street traffic below, so used one pass of the Sony Noise Reduction filter on the finished audio. This brought down the air-circulation hiss by about 8 dB. If this was an actual shoot, I would prepare the room by temporarily blocking the AC vents, and moving the set as far away from them as I could.
Here's a download link to the finished recording...
