I emailed Jean-Marc the arch.h about one week ago, not quite sure whether he actually received that email. Anyway, here I have an improved version of arch.h that I believe that it would be better, to use __int64 only if compiling on eMbedded Visual C++ compiler, so for any other compiler, keep it the same (use long long) ---------------------------------- Chan Kei Yuen (Kenji)

- Use MAC16_16 macros instead of (sum += a*b) and unroll a loop by 2. It increase performance when using optimized macros (ex: ARMv5E).

Hello, I'm trying to package some source files that link R to a broker using a Java API and the rJava package. I am successful doing the connection and operate on it using my R code. I would like to package the files and release the package. I created some S4 classes to hold several Java objects. I use WinXP and R 2.7.1. I've searched RSeek and the Wiki for help, but could not find a

Hi Jean-Marc, Hi Jim, I have also seen some problems with the 1.1.8 release on the C55x. So far I have boiled down the issues to the following: 1) We need our own "fixed_xx.h" header file. I don't know why, and haven't had time to investigate, but there is a definite improvement when I use the attached fixed_c55x.h file which has turned all the maths into inline functions.

Hi all I have spent the last three days evaluating CELT on our supported platforms. I found a bug in quant_bands.c, that due to processor/compilation differences did not cause an issue on x86 platforms, but is a problem on the MIPS processor embedded devices. When decoding on the MIPS devices, there was a lot of noise added during the decoding, the noise is mainly in the 15 khz to 21 khz range.

Please ignore my previous mail and patch, there is a new version :). Patch changes are: - Use MAC16_16 macros instead of (sum += a*b) and unroll a loop by 2. It increase performance when using optimized macros (ex: ARMv5E). A possible side effect of loop unroll is that i don't check for odd length here. - Add NEON version of FIR filter and autocorr - Add a section in autoconf in order to

Hi Jean-Marc, Based on the wonderful Speex project, I've created SpeexOutLoud, essentially a Speex codec port for Windows Mobile 2003 devices. I've included a sample project intended to show the usage of SpeexOutLoud codec in a Pocket PC application based on .NET Compact Framework. I'd request you to please go through the attached build, and include it as a contribution to the

is there documentation of what the various fixed point macros do, so I can work on converting more of the code to fixed point? Is there only one fixed point type, or are more than one used? --- >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

There is a problem in speex_preprocess_ctl. Both speech_prob_start and speech_prob_continue are set to 327.67 for all input values except 0 which results in 0. This is in floating point mode. I think the included patch fixes the problem. Mikael -------------- next part -------------- Index: libspeex/preprocess.c =================================================================== ---

Did you check it against the trunk in SVN? If it's not applied, and you can hook Jean-Marc up with an email address like yours, I'm sure he will get right on it. :) Tom Mihai Balea <mihai@hates.ms> wrote: > > Hi all, > > Did anything happen to this patch? > It seems to me that it fixes a valid issue, but I'm not an expert. > Anyways, I didn't see

I checked it against the latest code in the git repository and it wasn't there. Mihai PS: if JM wants a @hates.ms address, I could prolly hook him up. Especially if he throws in some VAD code that's not "a hack" :) On Nov 5, 2007, at 2:08 PM, Tom Grandgent wrote: > Did you check it against the trunk in SVN? > > If it's not applied, and you can hook Jean-Marc up

Firstly, running for more channels will not break my hack. All that's needed is to call RECOPLAY_MARK with different identifiers (say nb, wb or uwb) before doing the appropriate initialization. Secondly, my attempts to do the Gaussian in fixed point went like this : Define a new constant lag_factor_gauss that is manually set equal to exp(sqr(2*M_PI*lag_factor)/-2) by whoever changes the

Hi, It is better to replace this line in function filterbank_new: max_mel = toBARK(EXTRACT16(MULT16_16_Q15(QCONST16(.5f,15),sampling))); to max_mel = toBARK(EXTRACT16(sampling/2)); It gives the same but it seems to be faster and avoids overflow on 44100 kHz that prevents denoiser to process 44100 streams. (Yes I know that Speex should not pack 44100 streams but it does now and I use it). Best

is it safe to compile libspeex with -O3?

greetings, for those of you in the know, may i have some assistance in helping to make better decisions in purchasing more used server toys to install CentOS on please? :-) in the Compaq Proliant Rackmount DL380 line, the one that looks like the older 1850R is called a G1 meaning Generation 1 right? and then the DL380 G2 is a redesign that is gray and just has 6 drive bays up front correct?
