similar to: something wrong with narrowband and ultra-wideband?

Hello...i want to find the empirical rate for type 1 error using fixed trimmed mean. To make it easy, i'm referring to journal given by this website http://www.academicjournals.org/ajmcsr/PDF/pdf2011/Yusof%20et%20al.pdf. I already run the programme and there is no error in it but i got zero for the empirical rate of type 1 error. The empirical rate for the type 1 error given in the journal

Hi there, I've just started to work with the great speex encoder on ARM9-based embedded platform. This is my configuration: CPU: Cirrus Logic EP9315 @ 200 MHz (ARM920T) o.s.: Linux 2.6.9-rc2-ep93xx GCC: gcc version 3.3.3 (DENX ELDK 3.1 3.3.3-10) without MaverickCrunch support ogg library: 1.0 speex command line configuration: ./configure --enable-fixed-point --enable-arm4-asm The code is

Hello, I haven't found errors in your code. I implemented the test in the paper (the first, fixed symetric mean) and it also gives me zero Type I errors, when alpha = 0.05. Try to see the value of min(pv) or to plot the histogram of 'pv', hist(pv) and you'll see that there are no significant p-values, at that level. Anyway I'll continue to look at it, but my first

Hello Jean-Marc and all, I recently had a talk with somebody about CELP. He said, there is this federal standard 1016 (4.8kbps) with a reference implementation of the Department of Defense (only on Sun, unfortunately, if I got this right). This one is noticed in the manual already. He also said, since there is this implementation of the DoD, nobody would voluntarily re-implement CELP. If I read

Is there a bugzilla or similar for speex? I'm getting core-dumps on AMD64 speex (ubuntu) > speexenc -v speexenc (Speex encoder) version 1.1.11.1 (compiled Dec 9 2005) Copyright (C) 2002-2005 Jean-Marc Valin > speexenc /tmp/d04t05.wav d04t05.spx Encoding 16000 Hz audio using wideband (sub-band CELP) mode (mono) Segmentation fault > aplay /tmp/d04t05.wav Playing WAVE

hi, i am using AVTransmit3.java for transmitting audio, how can i implement JSpeex or speex for compression and encoding. please give me some idea about this. shankar.s speex-dev-request@xiph.org wrote: Send Speex-dev mailing list submissions to speex-dev@xiph.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.xiph.org/mailman/listinfo/speex-dev or, via email, send a

Hi all, I've built Speex 1.03 on Mac OS X. I encoded a raw PCM file successfully using: /usr/local/bin/speexenc raw_samples.raw --rate 44100 --be --16bit raw_enc.spx Warning: Speex is only optimized for 8, 16 and 32 kHz. It will still work at 44100 Hz but your mileage may vary Encoding 44100 Hz audio using ultra-wideband (sub-band CELP) mode (mono) If I decode to .wav, it works fine.

Hello, I would like to run a script over a speex file which determines, how long the speech contained in the speex file is. So I run through the ogg file, skip the first two ogg _pages_ (speex header and comment header, both contain IMHO only 1 ogg _packet_), and then count in any ogg page the number of the ogg _frames_ (which, unless I used -nframes while encoding, which I did not), and multiply

Take a look at this: peexenc --vbr -V --quality 4 audiodump.wav a.spx Encoding 32000 Hz audio using ultra-wideband (sub-band CELP) mode (stereo) Bitrate is use: 22400 bps (average -1268444817 bps) I'll take a look at what the problem is later today or tomorrow, but if anyone beats me to the bug, let me know before I spend too much cscope time playing with it.

I am transcoding mp3 to wave using ffmpeg I am then piping it to speexenc for speex encoding but the speex file size is 496 bytes after the command ends https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212927.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212949.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212954.html what am I doing wrong? bellow is

Hmmm, define working and stable :) <braindump topic="speexcat"> It began as a merge between speexdec and speexenc from 1.0beta3, with the encoding/decoding removed, and simply piped in and out from ogg

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, We'd like to announce the first draft for the Speex RTP profile. It was written essentially by Greg Herlein, with some help from Simon Morlat and I. We'd like to get some feedback on it before it is sent to the IETF. Basically this will allow all SIP based VoIP applications using Speex to inter-operate. For those interested, there's already Simon's LinPhone (www.linphone.org)

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, I've tried the same configure options on my system and it doesn't crash. I have the same glibc and gcc 3.3.2 (can you see if a newer gcc works?). Also, could you explore a bit with different options so we can narrow it down a bit. For example, does it work with the default CFLAGS or without --vbr or --dtx. Last thing, maybe it's the file. If so, please send me the smallest sample

System: Linux 2.4.25, glibc-2.3.2, gcc-3.2.3 (weird palindrome there), on a Williamette core Pentium 4 (1.6Ghz) system. I've tried both speex 1.1.5 release, and the current CVS (which self-IDs as 1.1.4), and the result is the same. I suspect some funk in the use of the SSE intrinsics macros.
