Subject: [flac-dev] 1.21 vs 1.3 encoding speed<br><div dir="ltr"><div><div><div>Hello,<br><br></div>I'm on a Mac and I'm noticing that
encoding via the flac command line is significantly slower with version
1.3.0 than 1.2.1. I'm encoding a 24/96 file to flac, both from wav and
aiff and both formats are showing the same speed decrease when using
1.3.0.<br>
<br>To give an idea of the speed decrease, encoding at flac level 8:<br><br><div>24/96 wav file<br></div><div>1.21: 61.05 seconds. ratio=0.690<br></div><div>1.3: 222.48 seconds. ratio=0.690<br></div><div><br></div><div>smaller 16/44.1 wav file<br>
</div><div>1.21: 14.28 seconds. ratio=0.487<br></div>1.3: 51.21 seconds. ratio=0.487<br><br></div>Also, 1.2.1 will not encode an aiff-c file, but 1.3.0 will. Is this change documented anywhere?<br><br></div>Thanks,<br>Scott</div>

a) What CPU do you have? Intel or PowerPC?<br>
<br>
b) There are no official binaries for 1.3.0. How did you obtain<br>
your flac 1.3.0 encoder?<br>
<br>
<br>
<br>
(I suspect that your CPU was made by Intel and your encoder was built without NASM...)<br>
