Test sequences for AMR Codec usage [2 Articles]
hazzyb4u - Jun 19 2006
Hi Everybody
I am working with the code Downloaded from 3GPP AMR Floating-point
Speech Codec (TS 26.104)..
i am looking at the Test sequences for AMR(3GPP TS 06.74 V7.3.0 )... 
Bit - exactness for the Fixed point iLBC code [2 Articles]
bells_8 - Jun 19 2006
Hi,
I would like to know what is the bit-exactness (up to how many bits the
output of the fixed point decoder output is matching with the floating
point decoder output) for th... Decoding two channel
"mas...@tin.it" - Jun 15 2006
The problem I met consist of two or more decode each one of them belong
to a different channel.

aysit - Jun 2 2006
Hi all,
There are two main roadblocks. It just seems like the only thing I can
verify to be working 100% error-free is the encoder portion of the
RESET SEQUENCE test vectors... decoding more than one channel with speex_encode_int() [2 Articles]

abhisheksgumadi - May 24 2006
Hi,
I am working on low bit rate speech coding.
I have efficiently quantized the lpc coefficients using vector
quantization methods. I am looking at an efficient way of quantizi... wiener filter implementation. [2 Articles]
yajn...@gmail.com - May 23 2006
Hi,
I am currently working on a speech enhancement project. I am implementing a noise cancellation system using Wiener filter.
> From what I read in the text books and from the n... Re: windowed sinc interpolation using FIR filter
wang...@163.com - Apr 25 2006
Hi,
It means that FIR filter is designed using truncated sinc function by hamming window. This FIR filter corresponds to a low-pass linear phase filter and is used to interpo... about wavelet decompostion of CWs?
wang...@163.com - Apr 25 2006
Dear all,
I want to use wavelet analysis to decompose and reconstruct CWs based on biorthogonal FIR linear phase filter banks , but I have found that the time delay of 3-leve... Speex command-line
devilal sharma - Apr 17 2006
Hi,
can somebody tell me where Speex computes residual
signal in the encoder. I mean the difference of
original and the reconstructed signal. I need to
output this residual sig...
