Airfoil has nothing whatever to do with FM radio as I think I've told this list 
about 90 thousand times already if you care to look at the archives you could 
probably do a count <smile>.

I mentioned Airfoil and associated products and software due to the original 
discussion of FM transmitters, I used to use them but I went away from that 
route because I wanted clearer reception, I wanted the sound to sound as it 
should sound directly from a pair of speakers connected to an amp or whatever 
and this is why I'm using Airfoil.  Now I'm sorry if I'm going to bore the 
pants off the majority of you by repeating myself again so I'll try and make it 
brief so you won't have to suffer too much misery.

Firstly Airfoil has nothing whatever to do with bluetooth speakers as some list 
members seem to think for whatever reason.  Airfoil is a tool which hijacks an 
application on your computer or an audio source on your computer - say Winamp 
as an application or the line in of a sound card being a physical sound source 
- and transmits that source over a home network so any device or computer 
capable of receiving that transmission or stream can decode it so you can hear 
it.

The easiest way to receive  anything from Airfoil is to use another computer 
and run the Airfoil Speakers software which will receive the transmission from 
Airfoil, if your computer has a digital out then you can connect this to a 
digital processor or surround-sound receiver and get that to decode the signal 
for you, very nice way of doing things because you get good quality sound and 
even surround-soud if your source has it.

If you don't want to use a computer then you can use Airfoil Speakers on your 
Iphone or Ipod touch or you can purchase an Airport Express.  Without going 
into too much detail yet again this little 3/3 inch box is in fact a network 
base station but it has an audio out jack which is both analogue and digital so 
you can of course put an Airport Express in another room and conceal it should 
you want to, you can then connect the Airport Express up to a radio with line 
in, again up to the digital input of a surround-sound receiver or digital 
processor and so on.

I'm not having a go at FM transmitters but really, they have their limitations 
and problems and they just will not give good sound reproduction, well I have 
seen those that do but for the money you pay to get them? You'd be better doing 
a job properly and streaming your audio so you can listen to a good quality 
sound and Airfoil is one way of doing that.
