<div class="moz-cite-prefix">I'll confess that I'm not a codec
expert but I'm referring to bitrate. A sample rate of 48kHz is
more than adequate, but a low bitrate makes a high sample rate
meaningless. CDs have a sample rate of 44.1 kHz with a bit dept of
16 bits and a bitrate of 1.35Mbit/sec. Most video streams have a
sample rate of 48 kHz. <br>
<br>
In MP3 (compressed audio) parlance, you can compress from 8 kb/sec
to 320 kb/sec bitrate while the sampling rate can be from 8 kHz to
48 kHz. Obviously, 128K bitrate MP3 audio sampled at 48 kHz sounds
much better than 32K bitrate MP3 audio sampled at 48 kHz. The
ultra-wideband audio deteriorates from low bitrate, not low sample
rate.<br>
<br>
I have done testing with the Opus codec at 48 kHz sampling rate
with another SIP client, </div></div></blockquote><div><br></div><div><div>That is because even if OPUS codec can use internally 48KHz sample rate that covers most human audible spectrum, the softphone you have used employs a smaller sampling rate like 8 or 16kHz, which renders the OPUS codec advantages useless, so you cannot hear any difference compared with let's say G722. Unless the whole audio processing chain works at the codec speed speed, the codec performance will not be visible.</div><div><br></div></div><blockquote type="cite"><div bgcolor="#FFFFFF" text="#000000"><div class="moz-cite-prefix">and the audio does not compare favorably

include Opus without including a bandwidth limit. Let
the limit be the codec's limit.<br>
