<BODY>
<P><FONT SIZE=2>I am positive, 4 bits per sample, 6000 Hz.</FONT>
</P>
<P><FONT SIZE=2>This is a default play/record setting for the older Dialogic R4 API and we need</FONT>
<BR><FONT SIZE=2>to play zillions (sic!) of files (messages) recorded this way.</FONT>
</P>
<P><FONT SIZE=2>Conversion issues:</FONT>
<BR> <FONT SIZE=2>- expensive</FONT>
<BR> <FONT SIZE=2>- resampling quality</FONT>
<BR> <FONT SIZE=2>- storage</FONT>
<BR> <FONT SIZE=2>- application changes</FONT>
<BR> <FONT SIZE=2>- etc.</FONT>
</P>
<P><FONT SIZE=2>Would be real nice and useful to have this codec.</FONT>
</P>
<P><FONT SIZE=2>Thank you.</FONT>

<P><FONT SIZE=2>> What I need is adpcm algorithm (4 bits per sample) with 6 KHz sampling rate</FONT>
<BR><FONT SIZE=2>> (6000 samples per second). This is 24kbps.</FONT>
</P>
<P><FONT SIZE=2>Are you sure you're not thinking of 3 bits per sample 8000 Hz ADPCM (also</FONT>
<BR><FONT SIZE=2>2400kbps)?</FONT>
