I'm doing some work where narrowband speex audio capture is happening and being written to file in the ogg container format. Later retrieval for reading will occur too. I've been using liboggz to do the file reading and writing and have obviously come across some things I don't seem to follow or have just got wrong. I can happily generate an ogg file using liboggz with some test

I''m building an app that allows users to sample .wav files. What is the best way to have RoR play sounds? I was just going to do something like this, but am wondering if there is a better way. Thanks! <script> function EvalSound(soundobj) { var thissound=document.getElementById(soundobj); thissound.Play(); } </script> <embed src="alf.wav" autostart=false

I'm trying to adapt decoder_example to to support more of an event driven model. I'm building an RTSP client/server where the client will have a function called everytime a new packet comes in. So, I want to queue up these packets to be played. My current attack is as follows (note this isn't very robust and I realized that): For first and second packet i grab all the header stuff

Dear Developers, I am currently involved in the co-ordination of archiving a whole heap of tapes containing audio (4000+ sermons for www.newcreation.org.au) to digital format. At present, all the tapes have been converted into mp3 @ CBR 40kbs, 44100 Hz... And this appears to play in most portable players capable of playing mp3's. (ogg vorbis isn't that widely supported, and many portable

Ok here is something I couldn't see on the description page. We need to convert to 8 bit audio right? I'm assuming narrow band is 8 KHz 8 bit. Wide band is 16 KHz 8 bit. UW band is 32 KHz 8 bit 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

Hi there, I've just started to work with the great speex encoder on ARM9-based embedded platform.

On my personal web pages hosted by my ISP I have a collection of speex files with names ending, as usual, in '.spx'. My ISP does not provide for scripting or CGI but thanks to the "Home-Brew Streaming" idea of Dr Tak Auyeng, www.drtak.org/teaches/ARC/speex/, my friends with Windows XP can listen to such a recording without the need for a prior download of the whole file and

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

Hi , I want to use the read.table to the following example 'data.txt' format: a b c d e f SPX LSZ 100 C 0 34.4 SPX LSZ 100 P 0 1.3 SPX LSZ 105 C 0 30.3 SPX LSZ 105 P 0 1.85 SPX LSZ 110 C 0 26.4 and I want to have the columns a,b,d read as the 'character' data, a the remaining columns as 'numeric'. What I did was:

I've checked to web for the format of the .spx file, and have not found anything complete. I've attached what I have deciphered so far. There are a few question marks in my tables that I want to understand better. I've also attached the .spx file that I used in the example values. I'm trying to take Speex-encoded data from an embedded microprocessor and put it into the .spx

This is a really good point, and definitely a recurring theme on this mailing list. :) I wonder, what are some better options for handling this issue, other than to keep saying "just use 8/16/32kHz"? - Extend Speex to support other sample rates (seems unlikely..?) - Integrate a resampling algorithm into libspeex - Maintain a list of recommended resampling libraries that work well

You should really do a check to make sure nbBytes isn't larger than 200, otherwise you're going to read past the end of your char array. fread (&nbBytes, sizeof(int), 1, fo); _____ From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Mo Win Sent: Monday, October 17, 2005 7:31 PM To: speex-dev@xiph.org Subject: Re: [Speex-dev] Error

Hi! I'm looking for a documentation of the .spx file type? I want/need to know how such a .spx file is built up. I want to create a .wav to .spx converter. And additionally a .spx player. I already searched the net and the speex site but I couldn't find anything useful. Maybe I'm missing something? Thanks for your help! Best regards, Peter -- Neu: GMX FreeDSL Komplettanschluss mit

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at

Jean-Marc, Ok, I understand. It's floating point but I don't have a mechanism in place yet to capture the source data. I'll do that, reproduce the problem, and put together a minimal sample program that can reproduce it given a data file.

iam using speex for the first time...iam using it in real time.....in command line as:- speexenc /dev/dsp old.spx Encoding 8000 Hz audio using narrowband mode (mono) when i played this encoded file old.spx in command line:- aplay pld.spx Playing raw data 'old.spx' : Unsigned 8 bit, Rate 8000 Hz, Mono then i decoded this old.spx in command line:- speexdec old.spx new.wav Decoding 8000

Would it help if I scale the input wav data before encoding to spx? One interesting thing is if I encode the same wav file to spx(or decode the same spx file to wav ) on Windows platform, then there is no such big clicking noise, samething is true if I use floating_point speex library to encode/decode on WM2003. Problem happens only on WM2003 using FIXED_POINT library. Thanks Yanxin -----

this is not really a development question, but i didn't find another mailing list to ask it. any idea why size of wav file doubles when it is encoded to speex and back to wav: $ ls -ls testi.wav 40 -rw-r--r-- 1 foo foo 40674 May 4 14:38 testi.wav $ speexenc --denoise --agc --quality 10 testi.wav testi.spx Encoding 8000 Hz audio using narrowband mode (mono) $ ls -ls testi.spx 20
