That was a bit misleading! You will get even bigger files.
In fact, while it is capturing the audio stream, vsound creates a ".au" file vsoundXXXX.au (XXXX is four random digits) which builds up at a rate of just over 10MB/minute, so a 30-minute program will give rise to over 300MB. When the program exits at the end, this is then converted to a ".wav" file which is much smaller (about 1/20).
For example, a trial I just made gave
vsound9324.au 327641624 bytes output.wav 13475840 bytes
However, both were present at the end so in total about 340MB of disk space was used up! It's only the final ".wav" file which is about 0.5MB/minute.
So you'll need to watch your disk space.
For those who don't already know, the URL given in ".ram" files (which points to a ".ra" file on the website) can have "start" and "end" times appended to it (and in some cases already does).
So, for instance, in the case of the "Yesterday in Parliament" RAM file "yip.ram", this contained
rtsp://rmv8.bbc.net.uk/radio4/news/yip_thu.ra
which is the URL for RealPlayer to get the stream using RTSP protocol.
If you only wanted the chunk between say 10 min 30 sec and 14 min 21 sec, you could append to this as follows:
rtsp://rmv8.bbc.net.uk/radio4/news/yip_thu.ra?start=10:30.0&end=14:21.0
which would reduce the download to the part you wanted (you can determine the bit you want by watching the time counter on 'realplay' while it is playing it out loud in a preliminary run).
Best wishes to all, Ted.
