Angie:
I suspect it is the 8KHz sample rate that is the problem. The encoder we =
are using has some problems with this sample rate, and I have seen it =
crash in this situation. If you can, try at least 11.25KHz next time.
Actually, I can't think of a good reason to use an 8K sample rate with a =
bit rate of 48 KBPS. The typical sample rate for a 48 KBPS MP3 file is 32 =
KHz, though you will find that NLS requires 22.05 KHz, which forces Level =
2 and sounds pretty good.
I guess what I am saying is that a file with a bit rate of 48 KBPS and a =
sample rate of 8 KHz is not any smaller than a file using the same bit =
rate and a much higher sample rate.

Hi Rob,
The sample rate is 8k Hz. the bit rate is 48 kb/s. I don't know what
was displayed just before the program closed because it happened so
fast. But I believe it might have been in the markup phase. I can try
again.
I was only using time compression.
The file is about 8.5 mb, and I can send it to you privately if you
wish.
Thanks,
Angie
