I bought a ADSP-BF533-EZkit-LITE V2.1 to develop a speech codec application using SPEEX. I have tested SpeexEcho project from both BlackfinSDK-Rel201 and BlackfinSDK-Rel310. When disabling SPEEX processing, i.e. using PASS-THROUGH mode, the output voice is ok, which is exactly as the input voice. However, when e...

...(fixed poin dspt) but need to use a more powerful dsp processor for our application. With the C5502 it takes 4.5ms to encode 2 (mono) channels with a 5ms frame @80kbits per channel. I need to reduce the computing time to reduce latency and leave some time for the DSP to perform some other tasks.The ADSP-21489 with it's floating point architecture seems like a good fit. It also runs faster @ 450Mhz instead of 300Mhz for the C5502. My question is : can I expect faster computing when opus is compiled in float mode rather than in fixed mode ? Thanks for your input.

The SOF ADSP vhost driver consists of two parts: a sound and a vhost part. This patch implements the vhost part of the driver. It handles QEMU communication with the vhost misc device and virtual queues to any VirtIO RPMsg guests. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski at linux.intel.co...

Anyone have any idea if the any of the Sharc or TigerSHARC DSPs are powerful enough to do realtime Speex? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

RPMsg over virtio has several problems. One is that it's not specced at all. Before we add more stuff, I'd like so see at least an attempt at descri...

Hi all, I am developing a VoIP application and have used SPEEX for that purpose; I successfully managed to port the codec in fixed-point to an ADSP-21364 processor, and the codec works fine in narrowband, wideband and ultra-wideband mode. Currently, I have chosen, in accordance with the speex manual, a 20 ms frame size in each of these modes: in other words, the input buffer for speex was set to respectively 160 - 320 - 640 samples. Now, I was...

Hi It pretty works for 16 bits samples but not for 24 bits samples. In fact, I am going to implement opus on ADSP-21489 (DSP processor from Analog Devices), I compiled "celt directory" from opus 1.1 and used "opus_custom_demo.c". It hasn't any problem with 16 bits samples but when I use 24 bits samples , there is no output audio. opus_decoder will still generate 16 bits samples and th...
