Analyser V 2.1:

Bugs: V 2.0
===========
-Sorry Folks! There was a big bug in version 2.0 who led to
an bus error when started with some ".CFA" files. The same error 
prevented the use of the program for people who don't have
the Analyser module. All this should function now!

New Features: V 2.1
===================
-Michael Wieck asked me if Analyser could use TT-Memory to speed
up on 68040 machines.
So V 2.1 tries to use TT-Memory for some tasks. Because i didn't have
a chance to test this feature tell me if it works.

-There where other minor changes mainly in the handling of the
Equaliser.


Analyser V 2.0:

*****************************************************************
+A Signal Generator is now a Part of the Program. Three kinds of
Signal-forms can be generated. 
1. Sine-waves
2. white Noise
3. Sine-wave-Sweeps

To activate the generator select the "Signal Generator" menu item
in the "Mode" Menu. To terminate the generator select the menu item
again or press the "Off" Button in "Setting Window".
If the Generator is activated two Sliders and a couple Buttons
are drawn in the "Setting Window".

With the buttons: "Sine-wave", "white Noise", "Sine-Sweep" the mode
of operation is set.

If sine-waves are generated the frequency can be controlled with
the left slider. Dragging or clicking this slider or the frequency
text at the bottom will set a new value.

To produce sine-wave-sweeps press the button. With the right
slider the duration of the sweeps is set. Duration means how long
it will take to cross the whole frequency range.

After pressing the "white Noise" Button white noise will
be generated.


The Attenuation of the generated signals can be set by clicking
on text field at the bottom of the slider field. Clicking with the
left and right mouse button will increase or decrease the value.
If the "shift-key" is held down greater steps are made.

**************************************************************
+For those of you who own the "Equaliser" an additionally menu title
was generated ("Equaliser"). It is now possible to use the 
Equaliser without leaving the program.

By selecting the "on" menu item in "Equaliser" menu the equaliser
will be started.
Two new windows will be opened and all Analyser Windows except the
"Setting Window" will be closed (Exiting with the menu item "off"
will reopen them).
The "Setting Window" will hold two sliders to control the
gain of the two channels separately and a few buttons.
The most important button is the "Bypass" button. After selecting
this Button with the mouse (or typing the shortcut "^B") the Equaliser
is completely bypassed.

The first of the new Windows shows the actual transfer function.
The transfer function is a graphic figure
that shows for every frequency an attenuation value. Additionally
the cutoff and center frequencies of the Filters are drawn as
coloured squares.
The frequency and attenuation of each filter can be set with
the left mouse button. The right mouse Button displays a
dialog box for numeric input. Moving the mouse over the
window will automatically select the nearest filter and highlight
the cut-off mark and the setting slot of the filter.

The second window shows the numeric parameter settings (setting slots)
of the six realized Filters.
All filtering is done on both channels simultaneously.
To set the numeric values of a filter click on one of
the six available slots. Each slot holds the parameter setting
of one Filter.
After clicking a dialog Box is drawn in which filter-type,
cutoff-frequency, gain, and Q-factor is shown.
When selecting a filter-type and input the parameters
the new transfer function is calculated after pressing the
"OK" button. 
 

The menu item "Low Frequency Mode" will start
an special Equaliser which is designed for manipulating low frequencies.
Therefore it has a four times higher frequency resolution.

Du to the complexity of this task a few restrictions are made 
("Low Frequency Mode" only!):

-Only low frequency can be manipulated. (a red Border in the transfer function
shows the maximum frequency-range).

-In this mode there is now way to record directly!

-There may be problems with overrun Errors while "play and record"-stereo
on falcons with only 4M RAM or  slow Hard-disks.

-There is no automatic feed through of an input from A/D,SPDIF/ADAT 
through the Equaliser to D/A,SPDIF-output.

There is the new button "Monitor" (in "Low Frequency Mode" only!).
A few Seconds after selecting the "Monitor" button the input is fed
through the Equaliser and directed to the output.
This works quite well. But there maybe some overruns when
you stuck in menus or dialog boxes (be aware of this fact!).


-As I've mentioned earlier Don't apply higher frequencies to
the graphic sub system than the original falcon does !
In such cases there is especially in "Low Frequency Mode" a
high risk of Hard-disk damage!!
