similar to: bug fix for speex_resampler_reset_mem?

Hi, I've attached a patch against SVN r14645 which adds GCC visibility information to all symbols exported from libspeex.so and libspeexdsp.so. It includes a configure.ac change to test that both the compiler flags and __attribute__((visibility)) works, and if so will #define EXPORT __attribute__((visibility("default"))) and if not #define EXPORT I've attached a diff output

Hi, Here's the (hopefully) final version of the resampler, now always using st->mem as the buffer area. It only allocates buffers on the stack when it's necesarry to convert the output between int and float. -------------- next part -------------- Index: include/speex/speex_resampler.h =================================================================== ---

Look, how about you start from the testresample.c file? Oh, and you seem to be reading 320 samples at a time and processing 640, so that can't be good (and even beyond that your code is wrong for other reasons).

From: Jyri Sarha <jsarha at ti.com> Semantics of inner_product_single have also been changed to contain the final right shift and saturation so it can also be implemented in the optimal way for the used platform. This change affects fixed point calculations only. I also added a new fixed point macro SATURATE32PSHR(x, shift, a). It does pretty much the same thing as SATURATE32(PSHR32(x,

Hi all, I have a couple of questions about the speex resampler: 1. Can a resampler state be used to process frames belonging to several audio streams? I would guess that there is information about the audio streams stored in the state so the answer is no, but it would be good to have some confirmation. 2. What is the best way to reset a resampler state? speex_resampler_reset_mem appears

Hi, *"That's in general not very reliable. You can get PEAQ to say all sorts of silly things." Can you provide me links for any more effective tools other than PEAQ? Which is more reliable for Speex resampler? * *"strongly suspect that it's just not compensating for the delay introduced by the resampler. Because higher quality means higher delay, you'd find that PEAQ

Hi Everyone, Just wanted to let people know that we've uncovered some problems with the speex resamplers in PulseAudio The problem generally manifests itself when having the following setup. * Server Sample Rate: 44100 * Resampler: speex-* (both fixed and float) * Playing a 48000 stream The problem only really manifests itself in the first 500ms or so of the stream and then generally

Be aware that inlen is an in/out parameter. It tells you how many samples the resampler read. That number can be smaller than what you passed -- in which case it means you need to buffer them and give them to the resampler again in the next call.

Colin, If you're using stereo audio with the resampler, there is a bug that can occur under certain situations (and maybe that's what's been happening to you). Check out: http://lists.xiph.org/pipermail/speex-dev/2009-August/007406.html With that patch, I've used the resampler extensively in many situations without any problems.

________________________________ Hi David, Thank you very much for your reply. Since I need to resample the audio in the program itself, I decided to try out the resampling API in speex. But now, I have another problem. The resampled sound is very much distorted and clicks appear quite often. (I have attached the source code I used for testing it below). The test data I had was a file sampled

From: Jyri Sarha <jsarha at ti.com> I optimized Speex resampler for NEON capable ARM CPUs. The first patch should speed up resampling on any platform that can spare the increased memory usage. It would be nice to have these merged to the master branch. Please let me know if there is anything I can do to help the the merge. The patches have been rebased on top of master branch in

Hello, some misc. cleanup patches for speexdsp, nothing big I'm not sure about how to submit patches, so this is a test balloon :) ultimately, I'd like to fix the FIXED_POINT issue, see http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html currently, I think the only way to find out how speexdsp has been compiled is to resample some bytes and observe the output; which is

Hi, I just built a sample application with speex resampler in linux and I tried to resample 8K sine wave tone mono to 48k using speex_resample_process_int. I am using a tool called EAQUAL for audio quality. I find the quality of Speex resampler to be decreasing when I increase the quality q of the resampler init function. Can some one give me pointers regarding this?? As per the API, if the

Hi everyone, I recently began using libspeex 1.2 Beta 1 on Windows using MS Visual C++. I have gotten a decoder and an encoder to work fine from the excellent sample code posted at the website. But I face a problem. I am working on using Speex in a program to play and create audio books encoded using Speex (currently testing it only; for these tests, I do not use Ogg to save the encoded
