Hi all, I've got a 400MHz XScale-PXA255 board, and I want to stream voice from it over a network connection at 28.8baud. This calls for a capable voice encoder which can encode at about 24kbps. I was damn happy when I found Speex and said goodbye to MP3 :) However, i'm still a long way from realtime encoding using speexenc, is...

...includes=/opt/arcom/arm-linux/include --with-ogg-lib=/opt/arcom/arm-linux/lib --enable-fixed-point I will of course try without ffast-math and funroll-loops, as they can decrease speed in some circumstances, but i'm open for further suggestions. The machine it's running on has an XScale-PXA255 processor at 400MHz, with a 200MHz bus.

I've been able to do real-time with about 20% CPU on an ARM 400 MHz. Here are the settings I used: - Compiled with FIXED_POINT (--enable-fixed-point) and ARM_ASM (--enable-arm-asm) - Compiled with gcc 3.3. (if you don't have gcc, you won't be able to use ARM_ASM) - Ru...

...some choices for the encoder based upon how quickly the pocket pc could convert files. I think that I chose flac -0 because of this and also I think that I may have increased the buffer already to 4608. However, I will do some additional testing. The cpu's used are in the ARM family. Xscale (PXA255) as found on the hp 5100/5500 series and 2200 series. The best performer right now is the Dell X50v 624mHz(PXA270), again same processor family. Because this is programmed I/O, media writes contribute largely to cpu utilization. FLAC helps, but it is a trade-off between lowering the amount of da...

...(much better than MP3 at 24 kbps anyway :) Last thing, can you try the code that's in CVS right now? I removed many float ops since 1.1.1, so it may already work better.

Hi, I just released unstable version 1.1.2 that contains more fixed-point work. Though it's still not 100% complete, enough have been done to make it run in real-time on ARM. In order to do that, compile with --enable-fixed-point --enable-arm-asm. All narrowband modes work in real-time with complexity 1 (some work with higher complexity) and some wideband modes also work (up to ~20 kbps) at
