<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>To minimize/eliminate transcoding, I am using mod native
file, with a set of transcoded prompts with the appropriate set of file
extensions. <o:p></o:p></p>
<p class=MsoNormal>Everything works as advertised when using the traditional
codecs such as pcma, g729, gsm.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But speex support is a bit of a challenge. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Freeswitch supports: speex@8000h@20i,
speex@16000h@20i, speex@32000h@20i.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I setup calls using these various codec flavors, I can
see using info (and of course detect by ear) that indeed the call is running at
the different ‘rates’.<o:p></o:p></p>
<p class=MsoNormal>I see that regardless of which one I use, the
“variable_read_codec” and “variable_write_codec”
remains “SPEEX”, but depending on the flavor, a
“variable_read_rate” and “variable_write_rate” of either
8000,16000 or 32000.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But when I try play a file when in 16000 or 32000, I get:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>2009-03-15 16:31:13 [INFO] mod_native_file.c:81
native_file_file_open() Opening File
[/usr/local/freeswitch/sounds/en/us/callie/all/16000/SUCCESS.SPEEX] <b><span
style='color:red'>8000hz</span></b><o:p></o:p></p>
<p class=MsoNormal>2009-03-15 16:31:13 [WARNING] switch_core_file.c:119 switch_core_perform_file_open()
Sample rate doesn't match.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I created my SPEEX files using: speexenc -w
<infilename> <outfilename> (note the –w option for 16kHz
wideband)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, even though the call is setup using a wideband 16kHz
codec, it appears that mod native file is expecting a 8kHz file for all the
SPEEX flavors.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What am I missing here? Is this module limited to 8KHz
rates? I am on 1.0.trunk (12530M).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have not yet looked at these codecs:
G7221@16000h, G7221@32000h, CELT@32000h, CELT@48000h, but as these
also have multiple rates for the same codec – I expect same issue.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am using ${ variable_read_rate } in the filename path, so fs
looks at a set of files encoded with a matching sample rate.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But looks like it’s always looking for a 8KHz file.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If you have had any experience with this, please let me have
your advice.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
