Bettter sound files?

The included gsm files sound rather rough through a good set.

I see there are sln16 files at but no sln files.
Asterisk does not recognize sln16 files.

(Tried copying sln16 to sln and get very slow playback)

How do I get the best playback?
What is the use for the sln16 files?


the gsm files have a problem because of a bug with the newer gcc versions
I have just downloaded the wav files from the ftp server and replaced the gsm files with the wav files and reloaded it works fine


I am surprised that only gsm are supplied with ABE (paid edition)

What format are SLN16? (they are bigger than wave)
