Port to uClinux
Hi, I'm trying a quick port of this terrific codec to uClinux, a Linux-derivate for mmu-less systems. I'm particulary interested in the alloc()'s the library does, and it's stack usage. In nb_celp.c I found two lines of code doing memory allocation : nb_celp.c: st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(float)); nb_celp.c: st =

Sample rate inaccuracy
Hi all, I'm having some problems with inaccurate sampling rates between sending and receiving party. (Using a simple raw UDP protocol sending packets from speex to speex) Both PC's have their soundcard set to 8 khz, but the samplerate seems to differ slightly between machines. The problem I have is that the sending machine sometimes samples with a slightly lower rate than the player

ARM w/ assembly & fixed point crash
I've targeted Speex to run under eCos with Thumb interworking using arm-elf-gcc 3.3.3 I'd written a small test case to verifiy the operation: #include <speex/speex.h> void speex_test(void) { SpeexBits bits; unsigned int frame_size; void *enc_state; float *speex_frame; cyg_uint64 t1, t2; int i; speex_frame = (float *)0x00030000; /* Address of Speex data

Fixed-point update
Hi, Now that Speex is getting pretty stable, I have decided to make a fixed-point/integer port the #1 priority. At this point, I'm looking for help from people with prior fixed-point experience and/or a good signal processing background. Anyone would like to volunteer? I have already started the port by converting to int some of the most used functions. While this should only have a small

Possible fixed point overflow/div 0 preprocess.c
Hi, I'll try to keep this as brief, yet descriptive enough to save everyone some time. If I'm off with this one please forgive me, but it has fixed my issues. I am not sure whether it is just my compiler (gcc 3.3.5) doing the wrong thing with the cast.

Port to uClinux
OK, what happens is that I try to allocate one big chunk of memory, so that no other allocation is needed in run-time. The biggest part of that memory is used for a custom stack I use everywhere because C doesn't allow variable-length stack arrays. The sizes I used will work for all configurations (any mode/bit-rate/complexity), but if you're only interested in a subset, you can probably

white noise problem when using -DFIXED_POINT
Hi there. We're trying to build a speex decoder for Palm OS (i.e. ARM7). No major problems porting thus far, but when compiling the speex modules with -DFIXED_POINT all the silent parts of the output are replaced with what sounds like high-power white noise. The spoken parts sound great, but all the silent parts in between speaking just sounds like white noise. We're using speex 1.1.6,

Fixed-point update
Just one thing I forgot to say: you need to add -DFIXED_POINT to the compile options.

favicon
im trying to figure out how to serve a favicon.ico for my app, does anyone have a line for Mongrel::Configurator? all i can see is that everyone seems to use the 404 handler...how boring.. uri "/favico", :handler => Mongrel::DirHandler.new(File.dirname(__FILE__)+"/favicon.ico") is sort of close, but it says The image ?http://m/favicon.ico? cannot be displayed, because it

Global stack on Cortex-M4
Hi all ! I just learned about the Opus codec and would like to try it out on my NRF52 (Cortex-M4) target.   I've been struggling a bit with the "trival_example.c" setup but repeatedly run into "hard fault" crashes when stepping through the code. Firstly; for a "bare bone" configuration, does the following compiler directives make sense ? UDEFS =

What? - 500 unless class Cart included
I have been struggling with a problem for a while, and now have a workaround, but I want to understand if something is borked in my config or if this is a bug. Setup: Mac OS X 10.4.3; Ruby 1.8.2; Rails 0.14.3 Problem: When I create a brand new project, I get an HTTP 500 status. If I add a Cart model, the 500 goes away: $ rails test create create app/controllers [etc]

Custom mode
Hi all ! If someone could give me a hint on how to proceed with the following i'd be very happy: I have a test setup on an nrf52832 (Cortex M4) in which I receive audio from a PDM microphone (64 sample frame) and pass it directly to an I2S device i.e. from ISR to ISR. With uncompressed audio this works just fine. Now I try to insert OPUS1.3 in the path but cannot make it work. The

white noise problem when using -DFIXED_POINT
It seems that with the file I posted, the decode noise persists all the way back to 1.1.1, when using --enable-fixed-point. When we configure with --enable-fixed-point-debug, the decode seems to be correct, even on 1.1.6. Hope this helps, and thanks for your time!

favicon.ico and robots.txt
Hello, I'm running an apache 2.2 webserver on centos 5.3. I'm seeing frequent requests for robots.txt and favicon.ico from the logs those files should be in the document root area. What are these files, is this something the rpm installs, or do i have to retrieve or generate them? Thanks. Dave.
