<div>There is a difference between rate of the modulator and sample rate. So we dont record at higher sample rate. The modultor runs at much faster rate, producing intermediate results and one needs a decimator to have to audio signal.</div><div>However I agree that in most cases a converter designed for say 192khz will offer 2 more decimation stages to 96 and 48khz. One can do it externernaly.</div><div>Your point is well taken. Why make the files so large? Downloading a 192khz file takes 4 times of 48khz. I am all for keeping enough band width, but not more than needed.</div><div><br></div><div>Regards</div><div>Dan Lavry</div><div><br></div><div><br></div><div><br></div><div id="composer_signature"><div style="font-size:88%;color:#364f67" dir="auto">Sent from my Verizon, Samsung Galaxy smartphone</div></div><br><br>-------- Original message --------<br>From: Bob Olhsson via ProAudio <proaudio@bach.pgm.com> <br>Date: 2/15/20 4:56 PM (GMT-08:00) <br>To: proaudio@bach.pgm.com <br>Subject: Re: [ProAudio] The High-Resolution Challenge <br><br><div class="WordSection1"><p class="MsoNormal">By the same token, the reason to down-sample is to save space.

For production, many of us feel down-sampling to no less than 96k yields better sounding signal processing in a final 48 or 44.1k product than a chain of up and down-sampled processes. It’s all about easier filtering.</p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Bob Olhsson 615-562-4346</p><p class="MsoNormal"><o:p> </o:p></p><div style="mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal" style="border:none;padding:0in"><b>From: </b><a href="mailto:proaudio@bach.pgm.com">Dan Lavry via ProAudio</a>:The reason to up sample is to enable easier filtering. <o:p></o:p></p></div><p class="MsoNormal"><o:p> </o:p></p></div></body></html>
