Thanks for the comments, Steve. The file was lossless m4a, so that shouldn't be the cause of any problems. I haven't come across a gravelly voice before, and I've recorded quite a few narrators. So it's in the voice, you think; that the raspiness here and there -- the gravelly sound -- is inherent. That those little valleys near the peaks are supposed to be there. I record two or three takes of narration, and I came across one instance where for exactly the same word in the same sentence, only minutes apart, one was gravelly and the other was smooth. That threw me. But, thinking about it, the gravelly sounds seems to occur when the recording is at a higher level, even though the narrator is standing in the same spot. Maybe when he pushes his voice, it 'cracks'. Very interesting. I had been suspect about my equipment and situation, especially in cases where a narrator has a boomy voice. I thought: room acoustics. For one old fellow I recently recorded, aged 89, I had to remove a bloom in the frequency response at around 400 Hz. I blamed room acoustics, but maybe he has a 400 Hz bloom in his voice, whereas the "Pelion" fellow sometimes has a gravelly sound, but no 400 Hz bloom. I'm beginning to appreciate that what's on my recordings is actually in the voice, and that we normally don't notice these artifacts in real life. Maybe the problem is: I'm doing the equivalent of pixel-peeping. Yes, very interesting. Ques: why might speaking across a microphone, instead of at it, reduce the gravelly sound?
