Hi,
I have made some tests on speech record from interviews. I am using a recorder + lav microphone. The recorder provides two audio levels (mic sensibilty).
a) I am not confident about setting the recorder to either low (1) or medium (2). With 1 I catch less noise/ambient sound than with level 2, but the volume is lower. I am thinking on recording in level 1 to avoid the noise (the interviews will happen in offices, then external voices and phone rings, even air conditioner or car noise from street would be minimized). Then I would normalize/increase the volume through post audio edition (some electronic hiss appeared after normalize but by using a filter I removed the hiss and the sound is clear). Does it make sense? (Attached there are the wave forms before and after treatment=>

b) On the other hand, the low level (1) of course provides a low wave form than level (2). Is it supposed that the level 1 provides less audio information than level 2? I mean, theoretically, should it be better to record the audio louder than record lower+normalize?
Thanks in advance,
Cadu
