I believe if you add the *decoder* lookahead time to the encoder lookahead time you are already referencing, you will get the numbers that you have calculated. --John On 4/11/2012 1:00 PM, speex-dev-request at xiph.org wrote: > Message: 1 > Date: 10 Apr 2012 22:07:20 +0200 > From: Thilo K?hler<koehlerthilo at gmx.de> > Subject: [Speex-dev] Speex Codec Delay Problem > To:

Hello R experts, I have two questions related to the nnls library (http://www.inside-r.org/packages/cran/nnls), and more broadly to linear regression with positive coefficients. Sample code is below the Qs. Q1: Regular regression (with lm) gives me the significance of each variable. How do I get variable significance with nnls? If there's no ready function, any easy way to manually derive

Can you, please, share exactly your setup - AIX version and well as how exactly you installed the compilers (=where from)? I can then try to replicate it. AFAICS there is no official binary for gfortran nor gcc 4.7 so it must be some 3rd party - which could also be a

Hello! I am encoding small snippets of audio (e.g. 100ms) that contain important audio from the first sample till the last one. (means they dont start/end silent). Doing so raised a couple of questions I couldnt solve by reading the docu/faq/internet search. 1. Does the "complexity" parameter influence only the speed of the encoder or also the speed of the decoder? (I need fast

hi there, I am new to mailing list so excuse me if I don't obey to the 'netiquette'. i am writing voice chat and speex is in the root of it. i write it in Java and use JNI to link with 'C'-based Speex 1.2beta. [I know of JSpeex but there are not implemented some features] recently i decided to use DTX feature of speex as well. the code follows. The problem is that no matter

>Neither C-- nor LLVM provide this.  Why do you need a GLR parser >specifically? http://www.cs.berkeley.edu/~smcpeak/elkhound/ Parsing with arbitrary context-free grammars has two key advantages: (1) unbounded lookahead, and (2) support for ambiguous grammars. Unbounded lookahead is achieved by allowing multiple potential parses to coexist for as long as necessary. Similarly, ambiguity

Hi Ralph, What speexenc does (Speex itself does not know about Ogg) is that it gives packet N the granulepos "N*frame_size - lookahead". In the case of narrowband, the first frame would have granulepos "1*160 - 80", so 80. I can't say about your example because Speex cannot encode a frame of one sample, which is a good thing becuse otherwise, the granulepos would be -79.

1. What to do with the last frame that is smaller then frame size? During encoding, the last frame is often smaller than the required frame size. In the sample code, proper number of zeros are padded at the end. So if I don't want those padded zero after decoding, I assume that it is up to me to keep track of the number of zeros. Is it right? 2. What does SPEEX_GET_LOOKAHEAD do? How to

Dear Jean-Marc and Peter: Thank you both very much for your time and advice. I did not realize that Lame MP3 code has a -r option (without reading its code). I have tried the suggested command lines verbatim with the added -r option, along with other combination of option settings. I could not figure out how to eliminate the distortion in the result, like voice turning either high or low

Dear all, in chapter 2 of http://jmvalin.ca/papers/aes135_opus_celt.pdf it is mentioned, that encoder and decoder has an algorithmic delay of 6.5 ms (lookahead and resampling delay). In Table 54 of https://tools.ietf.org/html/rfc6716 different delays for the resampler of the SILK encoder are given. However, I measure the same round trip delay for opus encoder->decoder regardless which

Hi, I was hoping to get some clarification on the meaning of algorithmic latency in Speex. For wideband signals, algorithmic delay is specified to be 34 ms (20 ms is the frame size and 14 ms is the lookahead). Does this number (34 ms) account for the double-buffering on the input? Assuming that the computation time and sound wave propagation time are negligible, should I expect compressed

Hi all, First of all, thanks to Speex developper for the all the job. I am trying to implement my own Speex DirectShow fitlers for VoIP following the documentation and sample code's. I am facing audio glitches when encoding - decoding PCM data. The encoder and decoder procedures are copied below. What about the lookahead size ? how shouw we apply it in encoding stage ? thanks in advance

Hey there I had implemented Speex encoding nicely in an application I was working on when I realized that I needed to change the API. I changed it, and the change somehow broke the speex encoding section of the code. The program writes SPX headers that other programs can read, but does not generate the rest of the file correctly. I have been through the guide "programming with
