Mark, there are three prob


Mark, there are three problems with the test audio.

1) The room is not quiet. So you can hear ‘other’ environmental sounds leaking into the recording, whether they are coming from outside, other rooms, a computer, whatever. Because you’re not recording in a studio the mic inevitably picks up these things which the human ear would not normally detect (but does detect in a recording, when it’s been amplified by a mic). Seal the room off from the outside world, or use a booth.

2) The room is echoing (as all normal rooms do). Pad it out with heavy blankets, furniture, foam, carpet. Cover hard surfaces and experiment and you’ll be amazed how it improves.

3) As Shasta and Josh said, the sound source (your mouth!) is too far away from the mic. Therefore, you have to turn the gain up more, and you therefore record more of the ‘other’ environmental & echo sounds (because they are louder in comparison to your voice, than they would be if you were closer to the mic).

Once recorded, you cannot effectively remove echo from a recording. There are a) some very time-consuming work-arounds, and b) some automated software-based algorithms to improve it a little, but (subject to this being a professional project), it would still not be acceptable.

I haven’t used the Canon DM-100, but lots of reviews are good, so if you follow some of the advice others have given above, you should be able to achieve a very good result.
