[asterisk-users] file command with alaw file
hi all, I install Asterisk 1.6 on Centos 5.2 (kernel 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux) and do record audio clip with mixmonitor() as alaw file (softphone is also configured with alaw active only). Using file command i can get the following information 983006584-20100517-125002.alaw: RIFF (little-endian) data, WAVE audio, ITU G.711 A-law, mono 8000 Hz But when i install the same system on Centos 5.5 (kernel 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux) i could get the same information with file command. File command recognized alaw file as JPEG image: 983006584-20100517-123825.alaw: JPEG image data I guess i may miss something when i setup the new on on Centos 5.5, but u dont know what it is. Anyone have idea about this? please help. Thanks in advance. Quyps -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] file command with alaw file
This may be totally irrelevant and it may send you down the wrong track, but I thought I would mention it: There is a bug which can prevent recent versions of asterisk from creating proper headers in WAV files. The bug shows up on Solaris systems but Linux is theoretically not immune to it. If you are creating raw ulaw or alaw files you should probably not expect any headers when things are working normally. But if you are creating wav files (which can contain alaw or ulaw data) and you find a bunch of null characters (0x0) in the header, then you may have hit the bug.

Re: [asterisk-users] file command with alaw file
Quyps-- I've noticed in general that the ulaw, alaw, gsm, slin files used and generated by asterisk do not have headers (the RIFF stuff), and asterisk is not expecting them. in general they will louse up Asterisk's ability to play the sound. They are just raw data and the extension on the file name (.gsm, or .ulaw, etc) is the only clue to the file format/contents. In general, if you need a sound file of your own making in a certain format, you can convert to most of the formats using sox in linux, but really, the best thing to do is record the source sound file in cd-quality sound WAV format, in 44 khz sampling rate, or higher, and then use sox to convert to 8khz format. Asterisk can do some of this via the file convert CLI command, ( on the asterisk cli, type "help file convert"). You'd have to judge for yourself if "file convert tt-weasels.gsm tt-weasels.ulaw" which would convert the 8khz gsm format to 8 khz ulaw, or "sox -v 0.7 tt-weasels.44khz.wav -r 8000 -c 1 -t sw tt-weasels.raw;" "sox -r 8000 -c 1 -t sw tt-weasels.raw -t ul tt-weasels.ulaw" which is the way the Asterisk sounds are produced from the the cd-quality sounds. They would seem a bit equivalent. I wonder if just "sox -v 0.7 tt-weasels.44khz.wav -r 8000 -c 1 -t ul tt-weasels.ulaw" would sound any better... you audio engineers out there may have an opinion. I've personally noted that not all linux distributions provide the same version of sox; some distribute sox with an absolute minimum of sound formats built-in. You may have to go out and find all the libraries and roll your own sox. murf On Wed, May 19, 2010 at 10:34 PM, Pham Quy wrote: > On Mon, 2010-05-17 at 17:49 +0700, Pham Quy wrote: > > On Mon, 2010-05-17 at 13:06 +0700, Pham Quy wrote: > > > hi all, > > > > > > I install Asterisk 1.6 on Centos 5.2 (kernel 2.6.18-92.el5 #1 SMP Tue > > > Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux) and do record > > > audio clip with mixmonitor() as alaw file (softphone is also configured > > > with alaw active only).

Re: [asterisk-users] file command with alaw file
Hi, How can I convert FROM ALAW file, which generated by asterisk apps (monitor, or record app), to format (wav or mp3) that is playable by music player?? Can Sox do this? I have an asterisk 1.6.2.6 on my CentOS 5.2. I record audio clip by mixmonitor app and use file command to check the alaw output, and here is output: - 983006584-20100517-125002.alaw: RIFF (little-endian) data, WAVE audio, ITU G.711 A-law, mono 8000 Hz - How could file command recognize the format as there is no header in the output file? Or Did I probably miss something making asterisk yield incorrect alaw files?

Re: [asterisk-users] file command with alaw file
Sox v14.1.0 doesn't play with alaw, but AFAIK, Asterisk has this function (this is from 1.4.30, think 1.6X has same functionality) CLI> help file convert Usage: file convert Convert from file_in to file_out.

Re: [asterisk-users] file command with alaw file
From alaw to wav, you can use Asterisk's CLI f" file convert /var/lib/asterisk/sounds/soundfile.alaw /var/lib/asterisk/sounds/soundfile.wav I want to have my record alaw automically be converted to mp3 (or wav) right after finishing recording. How can I do it in dialplan? We are going to connect our asterisk to E1-Euro ISDN. AFASIK, it uses G711 A-law for audio codec. Is it possible for me to save my recorded audio file directly as wav files without calling CLI's file command (it will be converted to mp3 later)?

Re: [asterisk-users] file command with alaw file
Might not be the answer you seek, but you could put a Q&D AGI in-line to do the CLI command for you. Something like this: Exten => s,1,answer Exten => s,n,record(file.alaw) Exten => s,n,AGI(alaw2mp3.agi,file.alaw, file.mp3) Exten => s,n,hangup Alternatively, you could replace the AGI with a System command. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Pham Quy Sent: Friday, May 21, 2010 5:04 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] file command with alaw file From alaw to wav, you can use Asterisk's CLI f" file convert /var/lib/asterisk/sounds/soundfile.alaw /var/lib/asterisk/sounds/soundfile.wav I want to have my record alaw automically be converted to mp3 (or wav) right after finishing recording.
