Sorry folks! Life was happening. Although, personally, I enjoy the croaking
Could still use some insight from anyone on making the file smaller. Unfortunately I'm not very tech savvy. I got the croaking by turning the resolution down to 8000 (instead of 48000). This was my attempt to reduce its size. Paul also recommended turning off the stereo. Don't know how to do that. There is an option to click on mono-track stereo, but when I do that, it doesn't seem to make the change. On my old computer, before the size issue occurred on my current computer, I remember using two track, and, I believe, 48000 Hz.
