Frequency and Phase Spectrograms
I know that there is a function, (spectro3D), that produces the Power Spectrogram. Are there R functions that produce the Frequency Spectrogram and the Phase Spectrogram? Thank you for your time. [[alternative HTML version deleted]]

PXE Booting linux on a Dell Poweredge SC1435
Hi, I'm trying to boot via TFTP using PXE, and it gets an IP, and "TFTP ." flashes before disappearing, and the machine hangs. This TFTP server and DHCP setup is known to work with many other machines. Can anyone help me debug this problem? What can I do to make the pxe output more verbose? -- Regards, Etienne Le Sueur Research Assistant - Gelato @ UNSW

Antw: Re: OPUS vs MP3
Hi guys, as MP3 and Opus have very similar objectives, I think the original poster's question was a valid one: Why does Opus have more artefacts in the lower frequency ranges than MP3 has? The spontaneous suspect that lower frequency artefacts may be more noticeably than higher frequency artefacts seems plausible, also. Is it a matter of energy (which is higher for higher frequencies)? When

Impossible two bugs in Opus
Hello. Me again. Have you tried to encode piano solo? Noticed high bitrate Opus gave? And there's also artefact at 15kHz which wasn't in the original audio. Visible with Spek program. Download FLAC and Opus both files, new link: http://www.filedropper.com/example_3 FLAC full: 1084 kbps; FLAC solo: 465 kbps. with --bitrate 160: Opus full: 158 kbps; Opus solo: 190 kbps.

question about tool collisions
Recently I got introduced to two packages: {seewave} and {audio} . Turns out they both have a tool to call a system audio tool, and in both cases the name of the tool is play(). Naturally these two tools do slightly different things with different arguments. So, what should a user do, and more to the point, what should R do? If I've learned the right things about environments, I

samples to dataframes
Hello all, I'll bet this is not complicated, but I really did hunt for information on it, and tried some ideas without success. Running Windows XP and R 2.3.1 I am using the Sound package to read in .wav files, and this works fine. The R object produced is of class "sample". I want to use some of the functions in the package Seewave to do further analysis, but this package

melting columns
Hello, I'm using R to run a acoustic analysis software called Seewave. I ask the code to extract a list of variables from my recording, and the program give ONE table for each of these. The tables consist of a two column data.frame with the time in column 1 and the frequency in column 2. However, for my purpose I need only one column with the time first and the frequency second. I tried

While significantly larger, Opus had produced significant ghost noise (much less than Vorbis did)... I experience the "same" low level noise even in a wav file, even on

library installation problem, invalid regular expression in help indices
Hi, I have a strange package installation problem after update to R 2.11.0 on Fedora Core 12. A colleague of mine with the very same Fedora and R versions doesn't have this problem, while logging on to his computer but installing from my settings and into my local library path also shows the problem, so it seems to be related to some of my environment settings. Installation of several

Can someone please have a look at this query on stackoverflow?
Dear Olivier, Many thanks for your reply. Very cool. You know what I thought ? I thought you had modified the A4 sheet size to compute the paperheight and paperwidth ? I wonder if that's another way of proceeding.

Hidden line algorithms and a different kind of waterfall
This is not the same as the recent thread on a waterfall graph. I'm thinking about the rolling FFT display used in acoustics and other spectrum analysis tasks. Here's an example of a very fancy 3-D waterfall display: http://www.ultimaserial.com/UltimaWaterfall.html I was just wondering if there are any simple hidden-line tools in R that I could use to draw simple waterfall displays.

And indeed again (I did not understand your previous question exactly at first), the 'hard-coded' definition of a landscape a4 sheet would therefore be: paperwidth=29.7cm, paperheight=21cm Olivier.

Scatterplot3d :: Rotating x tick labels by x degrees
Hi Alex, this should be related to the "las" argument of "par()" but actually it does not seem to be parametered in scatterplot3d. Searching the net for "scatterplot3d las" provides a link to: https://stackoverflow.com/questions/25458652/specifying-the-orientation-of-the-axes-labels-in-scatterplot3d You may try the solution that is provided in this link or consider

Dear Ashim, these are documented in the LaTeX 'geometry' package (see for example on CTAN: https://ctan.org/pkg/geometry). As I added in my response on Stackoverflow, several parts in the RMarkdown header actually concern information that are processed by LaTeX to actually generate the PDF, among which the 'geometry' line.
