Subject: Re: UEF

--=_NextPart_Lycos_0059271068457557_ID

MakeUEF, which is to be superceeded in the very near future, should be able
to read input straight from your 
soundcard (although on some operating systems it doesn't seem to be very
consistent in terms of line in or 
microphone in according to user feedback) or from a .wav, .voc, .au or, ummm,
whatever I believed the Apple 
Macintosh standard to be at the time.

If you're really feeling adventurous you might even grab the (ageing) beta
9 of my Electron emulator, ElectrEm, 
which is able to read tapes from the soundcard and simultaneously create
a UEF of them. If your program 
doesn't work on an Electron, then you could just do a *CAT or something -
the data written to the UEF is all the 
data recognised by the tape circuitry so that would be fine.

With respect to the supercession comment, MakeUEF is limited in that it uses
a quite simple data recognition 
algorithm which is only capable of recognising 'normal' tape data (the sort
the BBC/Electron operating system 
can save and load for you), and in producing output UEFs it rationalises
this information into what it considers 
to be the standard form, with default high tone lengths and baud rate.

Fraser Ross' upcoming MakeUEF replacement has a much more accurate data recognition
algorithm and doesn't 
do any internal rationalisation of data. However, it adds a few new chunks
and affects some older (but never 
used) ones, e.g. implementing a floating point measure of baud rate. Therefore
it pushes the minor version 
number up by one and some software may refuse to accept the new look files.
