[FFmpeg-user] aevalsrc question

Hey list,

Some time ago I posted a question about sweeping from one frequency to
another using aevalsrc and the t parameter of the expression. My
command line was something like:

ffmpeg -f lavfi -i aevalsrc=sin(262*2^^(t/10)*2*PI*t):d=10 test.ogg

and I'm still hearing higher frequencies than the desired output. I'm
also trying lots of other variations in the formula, and I'm trying to
do it without loading and storing commands.

What am I doing wrong and how an I fix this?
