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, and current libogg sources pulled down from subversion. Any help muc...

Compiling with either of these and -DARM_ASM seems to cause it to crash.

...et.   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 ?

Hello, Can somebody tell me something about the status of the fixed point code at this moment ? I did some tests today with the latest CVS version of speex, but enabling -DFIXED_POINT results in distorted sound in my test application. Is the fixed point code supposed to work properly at this moment ?

...rocessState_ member 'nb_adapt' is a signed integer. nb_adapt is only modified during 'speex_preprocess_run' when an unbounded increment is performed. When calculating 'beta' within 'speex_preprocess_run', I received a floating point exception even when compiled with -DFIXED_POINT. The reason is as follows: <original beta calculation within speex_preprocess_run> ... st->nb_adapt++; st->min_count++; beta = MAX16(QCONST16(.03,15),DIV32_16(Q15_ONE,st->nb_adapt)); beta_1 = Q15_ONE-beta; ... </> On my architecture(x86) at least the DIV32_16...

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

Dear expert: I would like to ask about the CPU resources need if implement the "opus codec" as the Bluetooth transmission devices?(music ) we do have DSP with SRAM..., how much-approximated memory space need for running the encode, decode algorithm? any minimum CPU power requirement ?? Thanks for idea. Regards sound analyst hogn kong -------------- next part -------------- An HTML

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
