[R] Use of ICA for sound

Hi, I'm looking at the "cocktail party" classic problem. I can see how to use ICA to separate the components. But, How do I then create new wav files of the separated sounds so that they can be played? Thanks -- Noah Silverman UCLA Department of Statistics 8208 Math Sciences Building Los Ange

Try the tuneR package. It will read in wav files and has other functions for manipulating sound data. On Oct 15, 2011 9:32 PM, "Noah Silverman" wrote: > Hi, > > I'm interested in doing some sound analysis with R. > > Does anyone have any experience/methods for reading in a wav file? > > -- > Noa

Hi Daniel, Thanks for the reply, that was the one missing piece! I had been trying to use the tapply() function, but was getting an error message about unequal length until now. I wrote: VAL_mean_xpart <- tapply(X[ ,2], PARTF, mean) and got the column 2 means by factors just as I had hoped. O

You could use the rgl package and plot a sprite at each of your points with the color based on the concentration: plume$col <- cut(plume$conc, c(-1,0.01,0.02,0.3,0.7,1), labels=c('blue','green','yellow','orange','red')) plume2 <- plume theta <- atan2(plume2$y-mean(plume2$y), plume2$x-m

Re: [R] Turning Data Frame Columns into Vectors

You access columns of a data.frame by column indices as in: X[ ,1], X[ ,2], etc. The index before the comma would stand for the row if you wanted to restrict those. The index after the comma captures the column. That said, you typically would not "extract" rows from the data frame but draw directl
