Hi,
I am really excited to hear about the ff7voice project. I heard a comment about clipping in the recording, which leads me to offer some advice from a semi-experienced garage band leader and multimedia guy.
For a good recording environment, an attic with exposed insulation is great! I did a recording (2 acoustic guitars--lead&rhythm, one vocal) on a minitape recorder and a powered Radio Shack lapel mic in my friends attic, with lots of books and exposed insulation, and it sounded like an off-the-shelf recording and remains the best unprocessed recording I've done. Of course, if you get desperate you can always pin up quilts on the walls and ceiling that are closest to you. Some more ideas are attaching quilts to the walls (at least closest ones) and ceiling, or getting a couple of those $15 Walmart foam mattress pads, may be nearly as effective as acoustic foam--I haven't tested these theories yet. If you try them, I would love for you to post your results.
As for the remark about clicks/pops in recording, this could be clipping, and is hard to repair unless you get a specific program with a feature or plugin to fix clipping. Ways to avoid this are: recording at lower volume and then normalizing, putting the mic off to the side (this can be bad especially in bad recording environments), or using a membrane mic.
If you want, you can make your own membrane mic. In my ventures in homebrew recording, this is most sure advice I have to offer. If you compare talking into the mic with a foam cover, holding the mic off to the side, talking into the mic directly, or talking into a membrane directly, you'll find that the membrane mic method gives you far superior results.
You'll need:
-Plastic bottle
-Plastic Wrap
-Scissors and possibly razor knife
-Mic: preferably a powered lapel mic--get one from Radio Shack, but only bother with the watch-battery powered one. Otherwise if you don't want to bother with batteries you can get a good stereo mic on eBay (the one pictured was from an eBay company that made homebrew mics--I can't seem to find them anymore).
Steps:
1. Cut bottle upper part off with scissors, then cut sides out only leaving two strips to hold loop to top (you can start the cut with a razor then continue with scissors for safety)
2. Attach plastic wrap with rubber band
3. Attach mic with twist tie or tape (twist tie avoids getting your mic gooey over time)
Tell me how your experiments go! I'd be glad to do audio editing and compression on the files too. Make sure you keep original unedited files in FLAC (lossless compression), and then you can export to ogg/mp3 or whatever you are using--but keep originals! You never know when you might need your originals. After all files are finished, I would glad to do the process of normalizing, equalization and compression so that all the audio throughout the game sounds uniform and volume varies only in situations where it should--sign me up if needed!
Well that's all the advice I have for right now, seeing as I'm pretty much just a self-made garage band guy.
