similar to: 11kbps narrowband on a 24bit DSP

I've never tried Speex on a 24-bit DSP, but I would suggest actually leaving the code (nearly) as-is. The scaling factors actually should not change because I'm using integer multiplications, not fractional multiplications. So what should happen is that the top 8 bits or 24-bit values and the top 16-bit of 48-bit values will be unused (filled with sign bits). There may be a few cases where

Hi, I've attached a patch against SVN r14645 which adds GCC visibility information to all symbols exported from libspeex.so and libspeexdsp.so. It includes a configure.ac change to test that both the compiler flags and __attribute__((visibility)) works, and if so will #define EXPORT __attribute__((visibility("default"))) and if not #define EXPORT I've attached a diff output

Apologies in advance if this is in a FAQ somewhere, but I've looked & lurked for a while and not found anything... I'm using Samba 2.0.3 on a RedHat 5.2 box to serve a mixed MS network (Win9x, Windows NT) (but testing with my NT4-SP4 notebook). I have a share where "dos filetimes = True" (also tried with this false) and "dos filetime resolution = False". Let me

We are running samba 2.0.4b to provide corporate print services. Everything with regards to printing is working like a charm. However, twice in the past two weeks, some of our Samba servers have disappeared from the WINS servers. The WINS servers are NT servers running 4.0SP5. The strangest part was that in one occurrence, it was the lone samba server at one location, but in the other

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? Peter -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, I'm trying to use speex for implementing a VoIP demo application using linphone on an embedded system. At the moment I'm not really able to do real time encoding, and thinking about making an assembler port for speex to the AVR32 architecture. The AVR32 is a new hybrid MCU/DSP fixed point processor running at 120Mhz in my application. Does anyone have experiences/info about the

Samba is causing a couple huge problems for the NT admins here since we switched a bunch of machines to security=server and started running nmbd. We're running Samba 2.0.2 and 2.0.3 on a mix of Solaris, HP-UX, and OSF1 machines. One, selecting a Samba server in Server Manager, then selecting Computer/ Services causes Server Manager to crash ("An application error has occurred, blah blah,

At this bitrate the encoder likely decides that it's better to put all the bits in the normal packet than use FEC. When you enable FEC it steals a lot of bits from the non-FEC content. Also, the use of FEC depends on the reported percentage of packet loss. The more loss there is, the lower the threshold for enabling FEC. Overall, the encoder attempt to make the best decision on a

Hello, playing a little around with speexenc/speexdec, I discovered that if I pass the "-n" or "-w" command line option to speexenc (version 1.1.10), I get a segmentation fault. Looking closely at the code, I found that the line: fprintf (stderr, "Warning: Trying to encode in %s at %d Hz. I'll do it but I suggest you try ultra-wideband instead\n",

Hi all, When encoding narrowband with speexenc I notice the bitrate is the same for qualities 3 / 4, 5 / 6, and 7 / 8 (8000, 11000, and 15000 respectively). I didn't test this on prior versions of the encoder so I'm not sure if this is something new, but am curious if there is a difference between the above respective settings (does quality 4 yield better results on narrowband than

Hi, What is the MIPS count for the narrowband decoder for 24.6 kbps mode??? Also what is the expected MIPS count on say C55x after optimization??

Hello to all speex developers I have question regarding payload length of narrowband speex in RTP. I were watching tcpdump of the xlite softphone and have found that it uses constant payload length 75 Bytes. The packet size should be variable, right? Why I get constant packet size?

The resampler will convert raw audio from one sample rate to another. You are starting with Speex-encoded audio frames. So, what you need to do is: 1. Run the media frames through the Speex decoder (look at Speexdec or testenc_uwb). This will give you raw audio with a 32 KHz sample rate. 2. Use the resampler to convert the audio from 32 KHz to 8 KHz sample rate. 3. Run the 8KHz audio

I downloaded speex-1.2beta3-win32 binaries, and used the speexenc.exe and speexdec to process the file male.wav download from http://speex.org/samples I used both the narrowband and ultra-wideband mode: >speexenc -n --quality 3 male.wav n3.spx Encoding 8000 Hz audio using narrowband mode (mono) >speexdec n3.spx n3.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex

Is there any way to access only the narrowband portion of a wideband stream? I'd like to be able to encode the audio only once, but allow members in a conference to have some rough selection of bandwidth, and allow them to move to a lower-bitrate stream if there is a need to do so.

It looks like I'll need to go further into the guts of speex to do this. I do, however, see some lines in nb_celp.c/nb_decode() that look interesting. I guess I'll play with it. I doubt that it will be terribly clean, though. Jean-Marc: Take a look at line 1195 in nb_celp.c (CVS). It reads "speex_warning ("More than to wideband layers found: corrupted

Hi List, Now I will send to you more specific what I am trying to do. I have one Asterisk Channel where receives Midia Frames in the codecs format: Speex UltraWideBand and Speex NarrowBand. When I use Speex NarrowBand the Asterisk is able to convert this frame to G711. But when I use Speex UltraWideBand the Asterisk don't convert it. Then I need in my Asterisk Channel Source include the Speex
