Adpcm, 6KHz codec
Is there a way to play adpcm, 6KHz in asterisk? If yes, where can we get
this codec?
Thank you.

ADPCM 4-bit, 6 kHz
I found some posts regarding this issue dating of September 2003, but no
real answer.
The ADPCM format supported by Asterisk (the .vox files) is 4-bit, 8 kHz. I
need 4-bit, 6 kHz, which is also a widespread Dialogic format, to help
migration.
Is there an existing format/codec for this? If not, can I make myself a
shared object in /usr/lib/asterisk/modules? Is this easy??? :-(
Thanks,
Yves...

ADPCM support with RECORD FILE
I want to record audio in ADPCM format. According to the "show codecs"
output of Asterisk, it looks like it supports adpcm. But I do not know what
to tell the "RECORD FILE" directive in my AGI script.
The RECORD FILE command usually has this form:

IAXy and ADPCM codec problem
Hi everyone,
I'm using the IAXy boxes and i'm having some trouble when I use it with
the ADPCM codec.
When I use the ADPCM codec only one person (out of the two of the
conversation) is able to hear the other, but when I switch to ULAW codec
everybody can hear the other.
The ULAW codec is too heavy for my bandwidth (64Kbits/s) and its sounds
choppy, the ADPCM codec sounds good but only in o...

ADPCM - vs - G.726
I have been looking at the medium-rate codecs in Asterisk - ADPCM and
G.726. Both of these are adaptive PCM codecs - the G.726 one is a little
more expensive in processing power, however both are 32k bit-rate.
I am experiencing problems using G.726 where the audio level is high. It
produces loud clicks as if clipping. For quiet audio however, it seems
fine.

ADPCM codec and IAXy device
Hi All;
I need to buy one IAXy device, but I discovered that
it supports only g711 and ADPCM codec, so I was wonder
that it does not support g729 or GSM?!
Anyway, what is that ADPCM and how much it consumes
bandwitdh? Also, asterisk support such codec? What its
name in the configuration?
Any advise?
Regards
Bilal

ogg player on a clie
...well.
If you visit the AeroPlayer FAQ, they claim that the Sony Clie DSP API
is unreleased, and thus not supported. But it looks like Sony *did*
recently release a library and API. I downloaded it this afternoon,
and was pretty disappointed. It only allows your application to play
a proprietary ADPCM block of data:
<p> The Pa1Lib library can play MIDI and ADPCM data.
* MIDI: SMF 0
* ADPCM: Yamaha ADPCM
o should not contain a RIFF header
o 4 KHz or 8 KHz sampling rate
o single channel (mono)
The Yamaha ADPCM format is not compatible with IMA...

It's possible to do a codecs translation during a call in Asterisk?
Hi everyone,
We are using the IAXy boxes and Asterisk over the internet and I was
wondering if Asterisk can do a codec translation during a call in order
to lower the bandwidth that the comunications consumes?
I mean, the IAXy boxes only support the ADPCM and uLAW codecs, but for a
certain number of calls our bandwidth runs out, then I think if Asterisk
can convert the signal that comes in ADPCM format (the lighter codec out
of these two) to another codec that use less bandwidth to interconect to
another Asterisk Server via IAX2 protocol.
We are tr...

RTP/RTSP streaming of GSM or ADPCM audio
Greetings:
It would be nice if Icecast supported RTSP; however I would
appreciate any suggestions for a small RTSP/RTP solution to
encode 8kHz mono audio in GSM or ADPCM and service multiple
unicast client connections. The ideal would be a black-box
hardware solution with an audio input and ethernet interface
similar to broadcast studio IP audio links or the network
audio capabilities of certain X-terminals. An acceptable
solution would be *nix or Win32 software...

Adpcm quality
...,1
exten => 99,2,Record,/tmp/pcmfile:pcm
exten => 99,3,Wait,1
exten => 99,4,Playback,/tmp/pcmfile
exten => 99,5,Wait,1
exten => 99,6,Record,/tmp/voxfile:vox
exten => 99,7,Wait,1
exten => 99,8,Playback,/tmp/voxfile
(put your own extension).
Pcm recording is OK, playback is OK.
Adpcm recording is noticeably worse. Adpcm playback is very bad/unusable.
Is it just us (all our servers with T400P and TE410P), or it's a common
adpcm codec problem?
Thank you.

I thought the author has two models, A-law and AMI ADPCM, which
both he extends. AMI ADPCM starts with 16-bit samples, but I'm not
sure if A-law is involved in that process.

Signaling tones in Speex
In case a system is incapable of fax relay or if it is disabled, one of the
easiest and safest options is to go for 40 kbps ADPCM compression (for fax
upto 14.4 kbps)..even am new to this problem and the fair bit of seraching
which i've done seems to suggest that the standard sloutions are to simply
'bypass' it else compress using ADPCM (40 k for fax upto 14.4 k, 32 k for
fax upto 9.6 k and so on), both of which e...
