re ad.table
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:

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

How to get podcasters to adopt Speex?
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

serving speex without a server
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

How to get podcasters to adopt Speex?
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

speexenc/speexdec doubles file size
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

.spx documentation
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

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.

speex 1.2beta1 encoding/decoding clicking noise on WM2003
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 -----

Speex .spx bitstream format
Dear experts, I am trying to understand the structure of the Speex .spx file, so I can packetize each frame in one packet for example, and in the receiving end, I can decode a file that has all the received frames (some of them may lost). I tried to figure out what is the delimiter used to separate the frames but I could not so far. I also tried to deleted some data from the .spx file or change

Error Executing sampledec in VC++
hey guys, I just compiled an application similar to sampledec.c (for speex 1.1.10) and it was fine but when I executed it, the app exited without doing anything. I'm using MS VC 6.0 and this was all I got - First-chance exception in sampledec.exe : 0xC0000005: Access Violation. Has anyone encountered this / does anyone know how to deal with it? by the way, sampleenc executed perfectly... When

File format information for .spx
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

Hi, I have been using R for over a year now. I am a very happy user. Thank you for making this happen. This is my first question to this list. I trying to add some functions to quantmod that would enable me to draw arbitrary lines and text and make sure they are redrawn. I have created following function: require(quantmod) # Add horizontal line to graph produced by quantmod::chart_Series()

Hi Steve, thanks for the advice. I placed the appropriate functions outside the while statement but I still get this error at the while loop: First-chance exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c.

I have (finally) posted my Speex wrapper classes. They are at: http://www.grandgent.com/spx/tgAudioCodec.zip I followed your recommendations and they worked fine with 1.1.0. However, I'm still having the same problem with 1.1.7 that I had the last time I tried to upgrade. I'm using the same code with both versions, except for calling speex_encode_int instead of speex_encode, and

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 1.2beta1 encoding/decoding clicking noise on WM2003
I am running speex 1.2beta1 on WM2003 using FIXED_POINT option, I got big clicking noise during encoding or decoding randomly, I got more noise if I spoke louder or made the MIC sensitivity higher, for example, when I encode the wav file to spx file, the original saved wav file does not have such noise, the noise is added only after it's converted to spx format.
