I'll upload a new patch changing that part, but the other parts can still be reviewed... 372593 3 crogers 2011-03-23 18:20:46 -0700 I also need to conditionally compile AudioBus::createBySampleRateConverting for chromium-only, or provide an implementation for the mac-port as well. It's not actually needed for the mac port, so will probably conditionally compile. 372628 4 86727 kbr 2011-03-23 19:43:22 -0700 Comment on attachment 86727 Patch Looks fine to me. Why don't you upload the final version of the patch and I'll r+ that. 373085 5 86835 crogers 2011-03-24 14:13:14 -0700 Created attachment 86835 Patch 373088 6 crogers 2011-03-24 14:15:06 -0700 AudioBus::createBySampleRateConverting() is now not compiled in for the mac port, since it's not needed there. I added #if ENABLE(WEB_AUDIO) to SincResampler which was missing it before. For efficiency, the resampling now first mixes down to mono (if necessary) 373167 7 kbr 2011-03-24 16:15:34 -0700 Looks good. r=me 373172 8 86853 crogers 2011-03-24 16:19:08 -0700 Created attachment 86853 Patch 373173 9 crogers 2011-03-24 16:20:54 -0700 Sorry, Ken I just uploaded another patch with a very minor change to conditionally include: #if !PLATFORM(MAC) #include "SincResampler.h" #endif 373198 10 86853 kbr 2011-03-24 16:50:18 -0700 Comment on attachment 86853 Patch OK. 373268 11 86853 commit-queue 2011-03-24 19:13:52 -0700 Comment on attachment 86853 Patch Clearing flags on attachment: 86853 Committed r81931: <http://trac.webkit.org/changeset/81931> 373269 12 commit-queue 2011-03-24 19:13:57 -0700 All reviewed patches have been landed.
