[asterisk-users] Better audio in than just 8k

Jerry, What if you specify a higher bitrate to mpg123?

You are limiting it to 8k with the 'r' option.

I convert my source audio files with sox to 16khz signed linear for
wideband hold music.

sox -c1 hold.wav -r 16000 -c 1 -e signed-integer -r 16k hold.raw

Then I rename the .raw file to a .sln16 and place it in the moh directory.

A human being should be able to change a diaper, plan an invasion, butcher
a hog, conn a ship, design a building, write a sonnet, balance accounts,
build a wall, set a bone, comfort the dying, take orders, give orders,
cooperate, act alone, solve equations, analyze a new problem, pitch manure,
program a computer, cook a tasty meal, fight efficiently, die gallantly.
Specialization is for insects.
