Resampler saturation
...l amplitude is 0.8 or 26214. After 2x upsampling, the peak level is about 30000 -> 114 % !!! (plus the output is kinda weird) Is this a bug ? Is it possible to fix it ? (I use version speex 1.2beta2, because newer versions just don't work on my platform) Best regards. -- St?phane LESAGE ATEIS International -------------- next part -------------- A non-text attachment was scrubbed...

Blackfin port on Visual DSP, Michael Shatz ?
...f you're reading this. Would you share your files ? Jean-Marc, I don't want to come back on the debate, but I think you should include the VDSP architecture. (there is also a problem with variables named "bank" which is a compiler keyword...) Best regards. -- St?phane Lesage ATEIS International

Patch for Analog Devices compiler & fixed-point AGC
...it, as it seems pretty easy: - I can live with a few emulated floating point operations for gain computation - extract gain mantissa and exponent - multiply fixed-point buffer by mantissa - offset spectrum exponent before IFFT reconstruction What do you think ?

VisualDSP++ with enabled BFIN_ASM
Hi I'm trying to integrate your speex codec on our custom Blackfin board and without uCLinux. I am using ADI-supplied VisualDSP++ IDE and corresponding toolchain. My question is: Is there anybody who ported speex with enabled BFIN_ASM to VisualDSP++ ? Best Regards, Stefan Voss -------------- next part -------------- An HTML attachment was scrubbed... URL:

VisualDSP++ with enabled BFIN_ASM
...'m using speex because of wide-band, and I'm pretty disapointed by performance considering it's slower than ADI's MP3 codec (10/20 MIPS for decoding/encoding of 44100 Hz @ 64 kbit/s). But maybe Jean-Marc would say the comparison is point-less ? Best regards. -- Stephane Lesage ATEIS International

Resampler saturation, blackfin performance
...) But you allocate them with speex_alloc instead of using the VARDECL/ALLOC macros. Converting the code to the stack_alloc mechanism could result in better performance with a scratch buffer in SRAM. I think I can do it for mdf.c, but I would need information for preprocess.c. -- St?phane LESAGE ATEIS International

Patch for Analog Devices compiler & fixed-point AGC
...option for me, because I need: - a small RTOS, where I can control hardware directly, and the VDK is just fine - an IDE with JTAG debugging, and VDSP is good enough. But maybe I'm wrong and we can debug using Eclipse without the gdbserver running on the linux target ??? -- Stephane Lesage ATEIS International

Resampler saturation, blackfin performance
...2, is it safe to enable "Round ps_size down to the nearest power of two" in the preproc ? can we do the same trick with the echo-canceller for window_size ? - are there buffers who could be placed in scratch memory ? (I don't see any speex_scratch_alloc inthere) -- St?phane LESAGE ATEIS International

Blackfin port on Visual DSP, Michael Shatz ?
...projects. Moreover you also have examples in this directory. Most users using IDEs are not familiar with make-files and don't know what files to include in their projects. (already seen this on the mailing-list) Maybe you should split it into: /libspeex /libspeexdsp /tests -- St?phane Lesage ATEIS International -------------- next part -------------- A non-text attachment was scrubbed...
