I am successfully generating a file with this command:

Code: Select all

swift -n Diane -o /var/lib/asterisk/sounds/tmp/Test_123.wav -p cst/f0_shift=.8,speech/rate=190,audio/deadair=2,audio/channels=1,audio/sampling-rate=8000 ' Test 123 '

But then from Asterisk v1.4 I get the following:

Code: Select all

[Feb  3 21:04:18] WARNING[1233]: format_wav_gsm.c:142 check_header: Unexpected header size 16
[Feb  3 21:04:18] WARNING[1233]: file.c:311 fn_wrapper: Unable to open format wav49

[Feb  3 21:04:18] WARNING[1233]: file.c:311 fn_wrapper: Unable to open format wav49

I have had this working in previous versions. Ideas?

I have asterisk running on my mac and swift generating audio files:

Code: Select all

swift -o /tmp/$agi_uniqueid.wav -p audio/channels=1,audio/sampling-rate=8000,audio/encoding=pcm8

as soon as I ask asterisk to

Code: Select all

stream file /tmp/$agi_uniqueid #

back comes...

Code: Select all

[Feb 27 10:56:24] WARNING[187]: file.c:316 fn_wrapper: Unable to open format wav49

Help! Anyone ever get an answer on this?

Thank you...
