MP3Encode
=========
Version 1.03 (22 Jan 1999)
Introduction
------------
This is an incredibly rudimentary frontend to the CMPA MP3 encoder. It allows
you to easily encode an MP3, in the background whilst you are working and
maintain some minor degree of control over it in an easier manner than using
the Taskwindow from your editor.
The reason for this is that I found that whilst encoding MP3's it was all too
easy to shut the machine down and ignore the message from the editor about
files not being saved because usually I had a number of taskwindows running,
most of which were idle and I'd forgotten about the MP3 encoding.
Usage
-----
Drag a PCM file (16 bit signed linear at 44.1kHz) to the iconbar icon. This
will start the encoding process. The menu gives you the controls you need to
pause and stop the encoding. The options window allows you to set the bitrate
to be used. I use 128 as that gives about 10:1 compression - you may find
different things.
You cannot quit MP3Encode while an encoding session is in progress. To quit,
stop the encoding process (you will NOT be warned) then quit the application.
Clicking on the iconbar icon opens the progress window. This shows you the
output from the encoder, and - in a little status pane below it - the count
of how far through the encoding is. Closing this window with adjust will
leave just the status window. You can move this by dragging it.
Clicking on the iconbar icon with adjust opens just the status window. If you
change the font/size of the text you will need to click 'Save' in the options
window to retain this setting.
How it works
------------
We use an incredibly simple taskwindow handler to manage the taskwindow which
is used by MP3Encode. The output handler is the generic display handler that
I use for most of my applications. As such, most of the operations you would
usually do with it are possible (clipboard, font/size selection).
Updates
-------
This program may (or may not) be updated periodically. By clicking on the
infobox window entries for Author and Version you can move directly to the
web pages for the Justin Fletcher and this application respectively.
Help and message files
----------------------
This application is fully !Help compliant and it is recommended that when
getting to grips with it the help should be used if only to give it some
purpose! It also supports the use of MessageTrans and therefore translation
to another language or changing the messages for the fun of it is much easier
than it might have been.
JFShared library
----------------
This application requires Justin Fletcher's JFShared library to function.
This can be obtained from Arcade and possibly other bulletin boards. A
version is currently being carried by Hensa, but for the latest version you
would be best off looking at Justin's web page (see below), or contacting him
by one of the other means below.
Acknowledgements
----------------
Many, many thanks to Dave Thomas for designing the icon for me!
Compatibility
-------------
This application has been tested on the author's RPC, but due to the lack
of friends with Acorns has not been tested on other systems. Therefore, it
ought to work on any RO3.6 machine. It is likely that it may work on RO3.1,
RO3.5, and RO3.7.

History
-------
Version 1.00 : 17 Jan 1999
First version written with variable bitrate, but no output
handling.
Version 1.01 : 18 Jan 1999
Added auto-filetyping of output.
Version 1.02 : 20 Jan 1999
Status display and progress window added.
Version 1.03 : 22 Jan 1999
Oops. I managed to get the shutdown check around the wrong way,
so it would only shut down if there was no encoding taking
place.
