<div dir="ltr">Pro tip:
<div><br></div>
<div>If the file path is /var/sounds/example.wav</div>
<div><br></div>
<div>you can create </div>
<div><br></div>
<div>/var/sounds/8000/example.wav<br></div>
<div>
<div>/var/sounds/16000/example.wav<br></div>

</div>
<div>
<div>/var/sounds/48000/example.wav<br></div>
</div>

<div>And it will auto-select the correct one that matches the

<div>The best practice is to transcode your wave files to the
diferent rates your clients use</div>
<div>If your clients are only on pstn side, 8khz should be
enough</div>
<div>If your clients is on sip side, better to generate 8, 16,32,

<div>Converting rate is a cpu intencive task and its part of

Hi, I am streaming a wav file who’s sampling rate is 44100 and
FreeSWITCH says sample rate 44100 doesn't match requested rate
8000. So I think it’s doing the conversion here. If so, is there
any CPU performance penalty while doing the conversion? What’s the
best practice here should I change the sampling rate of the file or
just leave it like that? </div>
