What soundfile format, is the one that uses least transcoding
during playback?
As I can see, I can choose wav or gsm. What sucks least cpu power, during playback to example a Zap channel? I would guess wav, but is this correct?
When you get down to it, the asterisk native format is slinear. Fortunately, you're in luck as Kristian Kielhofner did the asterisk community a big favor and had Alison re-record all the asterisk sounds, and he put them in slinear format. You can find them on the astlinux website (there's other formats, too): http://www.astlinux.org/index.php?option=com_content&task=view&id=38&Itemid=43 - Noah On 10/25/06, Matthew Rubenstein <[EMAIL PROTECTED]> wrote:
What's the native soundfile format for SIP? Any idea which soundfile takes the least CPU for mixing together in conferences? How about whether the CPU load for conferencing native data is greater/less than the CPU load for transcoding non-native data that is "CPU lighter" in the conference mixing phase?
