Speex bitrate
I'm using speex to encode wav files. How does the --bitrate n option (use bit-rate n or lower) afects the quality and time of the encoding?
If I don't use that option how speex determines the bitrate to use in encoding?
Thanks in advance

bitrate for slow modems
Depending on what you are broadcasting, for 28.8 I would go 16kbps and be
really safe...

Best and easiest soft phone for my Dad..
Hi,
Here is the situation.. My Dad is working on contract in overseas.. He
has internet access in his hotel.. He wants to be able to talk to my Mum
but the calls are expensive..
I have an asterisk box setup for my business and it has a public IP
etc.. My Mum has access to a working phone extension on this box..
I got my Dad to install X-Lite but for some reason it won't register and

Bitrate Question
Hello developers,
I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set.
A few more details about my configuration:
I am using SPEEX encoder version 1.1.12
I am encoding a narrowband

Bitrate in encoder
Hi,
I'm using the latest version of libspeex (checked out today) and have
some problems with checking the target bitrate in the encoder. Calling:
peex_encoder_ctl(globals->enc_state,SPEEX_GET_BITRATE, &bitrate);
Seems to set bitrate to 24600 no matter what the qualitysetting is.. The
functions used previous to this call is:
peex_bits_init(&globals->bits);

That clears it up - thanks. Is this in the manual?

Bitrate problem
But that's what a jitter buffer will do, eventually -
drop a packet. And it's better to drop a silence packet.
Cheers,

Bitrate problem
This is a common problem. Sound cards run at different
clock speeds (but your difference seems kinda high).
What I'd suggest is dropping silence packets once in a
while.

RTP routing..
Here is a question for all you routing guru's out there..
I am using an ADSL line (512/256Kbps) to connect from the internet to my
Asterisk server.. At a point I will run out of bandwidth so the cheapest
option would be to add a second ADSL line..
The problem is how will the routing work?
If I put 2 IP's on one NIC will the return traffice be routed back via
the gatway of the IP that

Quality and bitrate parameters ?
Hie,
I just don't understand one point in the speex's man page about the quality
and bitrate settings.
Are these settings's behavior same as Vorbis settings ?
Quality option set variable bitrate in order to maintain constant quality
during file and bitrate option set a defined bitrate , isn't ?
I'm not sure, so I'm pleased if you could say that I'm right.
A good idea is

HW-Speex: Fileformat and encoding process
Hi
I have just written a small c programm which reads in speex files and outputs
them as asci text numbers. This is necessary as for writing a hw testbench
for decoding tests, since thy only read ascii files :-(.I can't read the
bitrate properly from the header file. It's allways -1. Please see example
below and attached c programm. I wan't to check for a fixed bitrate (8000).

Speex configuration
Hi,
I'm trying to cover all Speex configuration options to set
quality/mode/bitrate
in my application and I was wondering if the following all makes sense:
- abr_bitrate
- use average bitrate and set it using bitrate parameter
- SPEEX_SET_ABR
- cbr_bitrate
- use constant bitrate and set it using bitrate parameter
- SPEEX_SET_BITRATE
- cbr_mode
- use constant bitrate and

PESQ calculated MoS-Values for Speex
Hello,
I just signed up to this mailing-list (note: my first mailing list at all),
because I'm having some problems related to speex.
Let me just introduce you to what I'm doing.
I am writing a short (really short) paper about VoIP techniques, especially
audio codecs for speech.

Wideband bitrate documentation
Hi,
On
http://www.speex.org/docs/manual/speex-manual/node11.html#SECTION001140000000000000000
the bitrate for Speex Wideband mode 9 and 10 is
9 34,400
10 42,400
On
http://tools.ietf.org/html/draft-ietf-avt-rtp-speex-03
the bitrate for Speex Wideband mode 9 and 10 is
9 34.2 kbit/s
10 42.2 kbit/s
I believe the draft contains the right values:
E.g. mode 10

problems decoding speex... please help
Hi all. I'm trying to decode speex using version 1.1.10's libspeex with

revisions. While running the program, encountered this warning:
"Packet is larger than allocated buffer : 38"

Multi-bitrate codecs
Anyone knows if there's a way to select the bitrate of those codecs
supporting multiple bitrates (eg. g.726)? I've tried searching and
googling a lot, but without useful results...

Speex codec for 8Kbps setting ?
Hi,
I am looking how to setup speex codec in codecs.conf for 8 Kbps and 6 Kbps.
In config file are many parameters for setting.
I don't know what is need to change for narrowbad like 8 Kbps and 6 kbps.
Any suggestion?

what I'd like to do
ok... topology.
486 with 10BaseT card hooking into 10/100 hub hooking into 10/100 switch hooking into cisco router combining two 128KbpsISDN lines into a consolidated 256kbps line.
listening on my desktop machine is fine, also 10baseT into the same hub as the server.
the bitrate on the mp3's is 128 (great for listening off the HD)
whats a good bitrate to encode for streaming audio?

15kbps mode. It does significantly better with a different
speaker (the male does better than the female), as well.
I'm considering purchasing a commercial PESQ license and wrap
the PESQ software in a server application. I could then allow
other folks to run PESQ
