Sub-band filtering
hi, I have a small and quick question. When speex divide the UWB speech signal into High and low bands, JMV said to me in HA that : "For ultra-wideband (0-16 kHz, 32 kHz sampling), I first split the band into wideband (0-8 kHz) and "very high band" (8-16 kHz). Then, the wideband itself is split into low (0-4 kHz) and high (4-8 kHz) band. So there's a total of 3 bands

[PATCH] Link libspeexdsp with libfftw3 when needed
When built with --with-fft=gpl-fftw3, libspeexdsp is not linked with libfftw3, while it uses symbols from it. This means every object linked with libspeexdsp should also be linked with libfftw3, but it is not something reflected in the pkgconfig file. Instead, link libspeexdsp with libfftw3 when --with-fft=gpl-fftw3, and remove explicit link with libfftw3 in objects build by the speex Makefile.

Compile flags for sampleenc sampledec.
I suspect I am missing something basic but I do not seem to be able to get the sampleenc and sampledec programs to work together. I think I do not have a compile swtich of flag set correctly. Backgound information: 1) 1.0.4 tar package 'make' worked and installed on a mandrake 10.0 linux 2) speexenc and speexdec appear to work fine. 3) testenc and testenc_wb work fine, though I

Problems with sampleenc and sampledec

difference with NB and WB
Ronald, Although you can give Speex data at any sampling rate with any mode, it's a good idea to use the right mode for whatever rate you have. Speex is built for speech (not just any audio in general) and is sensitive to what kind of stuff is going on in certain frequency ranges. If you tell it your data is at one sampling rate and give it data with another sampling rate, its idea of

Framesize for UWB vs. WB encoding
Hi there. I am having a little trouble understanding the frame sizes chosen by the codec. testenc_uwb.c from the speex-1.0 source distribution has a framesize of 640 hardcoded and makes use of this value exclusively. However, a mode query on the actual codec returns 320 as a framesize for this mode. int tmp; speex_mode_query(&speex_uwb_mode, SPEEX_MODE_FRAME_SIZE, &tmp);

Please help in understanding Speex echo cancellation
I'm using Speex in Windows VoIP application and trying to implement echo cancellationI'm using waveInXXXX and waveOutXXXX API. I'm doing quite simple thing: After buffer is played (I get MM_WOM_DONE message) I'm just copying it's content to temporary playback buffer After buffer is recorded (I get MM_WIM_DONE message) I call speex_echo_cancellation(state, recorded_buf,

Decoding raw problem on OS X with 1.03
Hi all, I've built Speex 1.03 on Mac OS X. I encoded a raw PCM file successfully using: /usr/local/bin/speexenc raw_samples.raw --rate 44100 --be --16bit raw_enc.spx Warning: Speex is only optimized for 8, 16 and 32 kHz. It will still work at 44100 Hz but your mileage may vary Encoding 44100 Hz audio using ultra-wideband (sub-band CELP) mode (mono) If I decode to .wav, it works fine.

XScale realtime encoding possible?
Hi, I have replaced most (but not all) of the float operations by integer operations, but it seems like the remaining ones take a long long time when emulated in kernel space (hence high system time). The other problem is that I don't have access to an ARM-based device (anyone wants to send me one?), so I'm doing all this blind... If you'd like to help, it can also accelerate things.

Framesize for UWB vs. WB encoding
Oops... You've just found a bug. Seems like you're the first one to use that call. Anyway, it's now fixed in CVS (both trunk and 1.0.x branch). Thanks for the bug report.

Higher Bandwidth at lower quality settings
Hi Jean-Marc, I thought at quality 3 (wideband) - wb_submode1 that the 4-8k band was not using a codebook table. From the code I can see that some sort of "lsp" encoding is performed. What exactly does this encode? (I assume lsp means line-spectral pairs) The reason I am asking is I'm comparing the "effective" spectral bandwidth of Speex against the
