Hi, Michael & Ulisses:
ULISSES: If you haven't already, I suggest you look at the hexView
package including the R News article cited below and the readRaw
function in particular. I just used readRaw(filename, offset=4,
nbytes=8) to read bytes 5:12 in filename; in this case, filename was

Hi, Carl:
1. I've used Audacity and it seemed fine -- though I haven't
used it much.
2. What's FTW? (None of the Wikipedia disambiguation entries
seemed to fit.)
Thanks,
Spencer

Or if people want to do it the R way:
Use the tuneR package and its readWave function that supports reading
parts of Wave files if the whole file is not relevant. You can specify
it in many units, see its help page. tuneR has also the tools to cut,
merge etc. Wave files and analyse it with bas

Once again, I would myself be inclined to farm this out
(in Linux) to the tools which come with the system. In this
case the command "dd" is useful (though one may need to be
careful about setting the options.
For instance,
dd -bs=1 skip=54321 count=31415 if=infile of=outfile

A more general question: What tools are available in R for reading
parts of binary files? 'scan' allows you to 'skip' a certain number of
records and read the next 'nlines'. Unfortunately, scan only seems to
work for text files not binary, and I cannot find a comparable function
that would w
Also with Linux you can add more swap memory(which I'm pretty sure R spills
into if it hasn't reached it's internal limits on 32 bit installations).
Windows pagefile is kind of obnoxious.

Hi Ulisses!
Yes, "get more creative" -- or "get more memory"!
On the "creative" side, it may be worth thinking about
using an independent (non-R) audio file editor. I'm
writing from the standpoint of a Linux/Unixoid user
here -- I wouldn;t know how to set ebout this in WIndows.
You could use R to
If you are running Windows it may be as simple as using memory.limit() to
allow R more memory -- if you are on another OS, it may be possible to get
the needed memory by deleting various things in your workspace and running
gc()
Of course, if your computer's memory is <3GB, you are probably going
