Hi All !<br>
<br>
My recent blog post about lossy encode clipping has had quiet a bit of attention:<br>
<br>
<a href="http://productionadvice.co.uk/spotify-upload-true-peak/" rel="noreferrer" target="_blank">http://productionadvice.co.uk/spotify-upload-true-peak/</a><br>
<br>
Including an email from Robert Bleidt @ Fraunhofer. He’s asking if I have specific examples of encodes that have “baked in” the clipping, because his position is that it shouldn’t happen, these days.<br>
<br>
I’d like to give him a helpful reply and I’ve experienced problems myself in the past with encoding from Logic and Audacity, for example, but the truth is I don’t have a collection of examples on hand to offer him.<br>
<br>
Do any of you have recent examples that I can point him at, or know for sure of current encoders that consistently have issues with extremely loud content ?<br>
<br>
Thanks for any suggestions,<br>
<br>
Ian<br>
