Any buffering on server?
Hi, Thanks Mike. So is there any buffering done on the server, or is it all on the client? i.e. when a server first connects, does it get a "burst" of packets until it catches up to the current time?

Sensitivity to sounds with frequency
Hi, I've looked in various FAQs and web pages for this info, but just can't seem to find it. When two tones of two different frequencies sound equally loud, what's the (rough) relationship between their power? This is for percussive sounds in music, but I assume it's roughly the same for all sounds. The ear seems more sensitive at high frequencies. For example, when you

Writing a client
Hi, I need to write an Icecast client, it seems pretty straight forward: open up an HTTP connection, send the request, strip off the header and send the rest to the ogg vorbis decoder. My only question is: how does the server know or not know when a client is behind? Should my client only read from the socket when its buffer isn't full? Or is there some other mechanism? What would happen

Ploting a function of two arguments
Hi, I've written a function: myfun <- function(x, y) { // blah blah } and I want to graph it. My plan is to use persp(), and my question is: how do I create the array of values? One possibility is: x <- seq(0, 10, by=.1) y <- seq(0, 10, by=.1) inputs <- <somehow create an array of x,y pairs> outputs <- apply(A, c(1,2), myfun) The "inputs" array would

Converting a number of minutes to a difftime
Hi, I have a variable "m" that contains the number of minutes that something lasted, e.g. m <- 139 I'd like to convert it to a difftime, so I can add it to the POSIXct start time. But as.difftime seems to want a character string, with at most two characters for the minutes. All other conversion functions seem to take strings as well. What am I missing? Thanks, Martin

Adding "sum" to derivatives table
Hi, Trying this: deriv(expression(sum(x)), "x") Gives the error message: Function 'sum' is not in the derivatives table I'd like to add it, is this difficult? If not, where is the derivatives table? However, give how basic "sum" is, I suspect it would have been added if it were straightforward. Do functions in the derivatives table need to be

Statistical significance of a classifier
Hi, I have a bunch of data points x from two classes A & B, and I'm creating a classifier. So I have a function f(x) which estimates the probability that x is in class A. (I have an equal number of examples of each, so p(class) = 0.5.) One way of seeing how well this does is to compute the error rate on the test set, i.e. if f(x)>0.5 call it A, and see how many times I

ogg_stream_packetout() and stream mixing
Just to make sure, if I'm mixing 2 streams at the page level, and using ogg_stream_pagein() and ogg_stream_packetout() to extract them, I need two ogg_stream_states, one for each logical stream, and I need to ensure that each ogg_stream_state only sees pages of it's own type, is that right? - Martin --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

ogg_sync_state with interleaved logical streams
Hi all, I'm mixing logical streams at the page level. One stream has vorbis data, the other has my own data. Do I need two ogg_sync_states or just one?

Pages and Packets
Hey all, I've been going over the docs, can someone confirm my understanding? - According the the file format, it's possible to have many packets per page. - Packets don't have headers. The only "free" information for each packet is its length. Does beta 4 encode/decode multiple packets per page properly? Thanks, Martin --- >8 ---- List archives:

Encoder differences, beta4 -> 1.0rc1
Hi all, Were there encoder differences between beta4 and 1.0rc1? A precompiled oggenc for Windows identifies itself as beta4, and from a certain mono file produces 53.3 kb/s files, whereas one I've compiled myself, identifying itself as 1.0rc1, produces 55.9 kb/s. Is this a feature or a bug? Also, all the links to images at the top of: http://www.vorbis.com/download_win.psp are broken.

Determining stream type
Hi, I need to encode some extra information in my sound files, in a separate logical stream. Some day I'd like this to be streaming, so for each page, I need to know whether it's a vorbis page or one of my own extra-info pages. I've read the "Ogg logical bitstream framing" document, but at the Ogg level the only "structured" info is the page header, and that

OT: compiling oddcast DSP
Hi, There's a rather serious problem with the Oddcast DSP for Winamp, when you stream in vorbis format over icecast2, it drops ~ 1/2 sec of near the beginning of every song except the first. I tracked this down, it turns out oddcast drops the last vorbis page of every stream. (The DSP doesn't receive the new metadata until after the song has been playing for a second or two, which is

Am I missing something?
Hey all, If my understanding is right, there's a serious big in vorbisfile.c, in the routine _fetch_headers(), which will only show up when comment packet spans multiple pages. The code to read the first 3 Vorbis packets ogg_stream_pagein() once, then calls ogg_stream_packetout(). The problem is that ogg_stream_pagein() only adds a single page to the ogg stream state, whereas

Will Vorbis happily decode packets with random data?
Hi, For my application there's been some talk of people hiding viruses in Vorbis files. While the possibility's remote, I'm exploring ways to verify that a give file really is a Vorbis file, and doesn't even have long streaches of executable code in the middle of it. If a file has valid Ogg page structure, and a valid Vorbis header, but somewhere in the file a packet has been

Computing sums of the columns of an array
Hi, I have a 5x731 array A, and I want to compute the sums of the columns. Currently I do: apply(A, 2, sum) But it turns out, this is slow: 70% of my CPU time is spent here, even though there are many complicated steps in my computation. Is there a faster way? Thanks, Martin
