>Hello list, >it seems that Asterisk is unable to convert a wav-file into an alaw-file : >[r...@asterisk testing]# asterisk -rx "file convert testExtended2.wav testExtended2.alaw" >Unable to open input file: testExtended2.wav >[r...@asterisk testing]# asterisk -rx "file convert testLong2.wav testLong2.alaw" >Unable to open input file: testLong2.wav >The wav-file is MONO, 8000Hz according to SoX and confirmed by the sox mailinglist >(http://sourceforge.net/mailarchive/message.php?msg_name=4C6A4661.9000209%4 0telenet.be) >[r...@asterisk testing]# soxi testLong2.wav >Input File : 'testLong2.wav' >Channels : 1 >Sample Rate : 8000 >Precision : 16-bit >Duration : 00:01:27.05 = 696427 samples ~ 6529 CDDA sectors >Sample Encoding: 16-bit Signed Integer PCM >Why then can I not use Asterisk to 'convert' to alaw ?! >Kind regards, >Jonas. As I interpret what I have read in this forum over the last several months, there is not really an "ALAW" format. If you do a sox (don't remember if you can do in native Asterisk) convert to RAW (headerless) format, Asterisk is happy to consider that as ALAW.
