<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">it is mentioned, that encoder and decoder has an algorithmic delay of 6.5 ms (lookahead and resampling delay).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">In Table 54 of<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">https://tools.ietf.org/html/rfc6716
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">different delays for the resampler of the SILK encoder are given.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">However, I measure the same round trip delay for opus encoder->decoder regardless which maxplaybackrate I use.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">The round trip delay corresponds to the 6.5 ms.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">Therefore my question:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">How is this 6.5 ms algorithmic delay distributed between encoder and decoder?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE">May it be, that the reference implementation uses 5.75 ms at encoder side and 0.75 ms at decoder side (using equal resampling delay for encoder and decoder)?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:DE"><o:p> </o:p></span></p>
