11kbps narrowband on a 24bit DSP
Hi,
I am using speex 1.2beta2 on a 24bit DSP that has a severe program and
data space limitations. I am only interested in the speex decoder for
11kbps narrowband implementation.
I am using the following parameters and structures
160, /*frameSize*/
40, /*subframeSize*/
10, /*lpcSize*/
17, /*pitchStart*/
144, /*pitchEnd*/
/* 11 kbps medium bit-rate mode */
static const SpeexSubmode nb_submode4 = {

11kbps narrowband on a 24bit DSP
...d be
changed to 24-bit ones, but don't bother with that in the short term.

DSP C5xx decode to pcm 16bit
I am wont to decode a speex 11kbps 8kHz 16bit to a raw data 8kHz 16bit LSB on a c5509.
Trying to understand the "testenc-TI-C5x.c" exsample, but it looks to me wary complicated.
Is there more documentation for the exsample or a decoder exsample available?
Can somebody help?

Simple Example isnt working (ssh/bulk traffic)
Hi,
the script below should allow to get ssh connections running well while
downloading, but even the 100kbps (100kbyte/s?) doesnt work - can still
download with 500+kb/s. Whats wrong?
INTERFACE=eth0
#clear all on $INTERFACE
tc qdisc del dev $INTERFACE root
tc qdisc add dev $INTERFACE root handle 1:0 htb default 15
#root qdics, allows borrowing for its children
tc class add dev

new assembler port
....
Does anyone have experiences/info about the computational power
requirements, e.g.
what quality/bitrate and complexity of encoding seem to be realistic as
target operating
modes. I've run some tests with speexenc, encoding a 1minute 16bit PCM
8khz speech
file, which took 3m53s to encode at 11kbps CBR/complexity 3.
For finding a starting point for the assembler port I did some analysis
of the encoding with
valgrind-callgrind. Perhaps some of you have already done similar work
and could share
a bit of their experience?
To loose some words about myself, I'm a student of information

Accumulating latency in nsv stream
...any difference in the symptoms.
The configuration:
icecast 2.2.0 on Linux 2.4.27
nsvcap (nsvenc doesn't support the video driver properly) sourcing
on Win2kServerSp3/PIII-500/384M/Bt848-btwincap:
VP3 codec configured for est 15kbps/7kbps key, 1fps output,
1fps capture, 6 -> 11kbps actual bitrate, no audio;
nsvcap reports d=107 vinq=0 ainq=0 (0 dropped) after 10 hours.
I've seen mentioned that frame rates should be in multiples of two
with key frame rates evenly divisible, but I am after the lowest
possible rate which seems to be 1 fps even though the input frame
