Hi, I'm porting speex as a DSP task to run using the DSP gateway project. I have some results, but I still need some improments, because I'm still getting some error messages in the mail box system... If someone wants to help... it would be useful. 2006/1/16, Ralph Giles <giles@xiph.org>: > On Mon, Jan 16, 2006 at 04:43:56PM +0100, Christophe Augier wrote: > > > i'm not an expert in dsp but i'...

Hi, i'm not an expert in dsp but i've seen there is some code to run speex on omap C5X dsp so i was wondering what is the status of this code. Actually my goal is to run a voip application which uses gstreamer on an OMAP 5912 board. As there is already a speex codec for gstreamer, i was wondering if this plugin can already use the dsp power or if there is the need for a new plugin. thank

Hello, This patch introduces ARM NEON Intrinsics to optimize kf_bfly4 routine in celt part of libopus. Using NEON optimized kf_bfly4(_neon) routine helped improve performance of opus_fft_impl function by about 21.4%. The end use case was decoding a music opus ogg file. The end use case saw performance improvement of about 4.47%. This patch has 2 components i. Actual neon code to improve
