AudioWorks (DEMO version)
=========================
This is a demo version of the AudioWorks Digital Sample editor package.
In the directory "DemoSample" are a few demonstration samples to play with.
They are mostly 8 bit, Logarithmic, 20833 samples/second. Some of the
samples are also stereo. A few of the samples also demonstrate repeat loops.
In the directory '$.ProfSample' you will find versions of these samples,
plus many more in 16-bit Linear Signed 44100 samples/second format.
This file includes information to help you familiarise yourself with the
program, as well as some important notes.
Features
========
Its features include:
* Editing and playback of mono and stereo samples of the following types
8, 12 and 16 bit Linear Signed
8, 12 and 16 bit Linear Unsigned
8 bit VIDC Logarithmic
8 bit µLaw Logarithmic
* Loading/Importing of samples in the following file formats
AudioWorks native format
DataVox
Armadeus
SoundSynth
Tracker samples
Unpacked Digital Symphony samples
Creative Voice File (.VOC)
Sun audio (.snd/.au)
NeXT audio (.snd/.au)
Microsoft WAVE (.WAV)
IFF 8SVX
Raw (headerless) data
Samples may also be extracted from
Acorn replay movies (Soundtrack extracted)
Tracker music files (Any instrument(s) may be extracted)
SoundTracker/ProTracker music files (Any instruments may be extracted)
Most formats are automatically recognised from the file content, so
are correctly loaded even if the file type is incorrectly set.
* Saving/Exporting data in a variety of formats including
AudioWorks native format
DataVox
Armadeus
Acorn Replay (audio-only) Movie
Microsoft WAVE
Raw data
NOTE that saving has been disabled in this demo version
Further exporters may be present in future release versions
* Recording of samples to memory or direct to hard disc, from any sampler
for which an AudioManager driver is available. Currently this includes
the Wild Vison Eagle and Lark cards - AudioWorks is included in both of
these products as standard.
* Editing of up to 48 samples concurrently.
* Fully multitasking operation - all effects operate in the background,
and effects may be applied to multiple samples at once.
Up to 8 samples may be played simultaneously
Each sample includes a play cursor to show what is playing.
* Works under RISC OS 2 and 3. Supports extra RISC OS 3 features.
* Multitasking Spectrum Analysis and Oscilloscope display windows.
* Interactive Scale View dialogue, and various display options.
* Keyboard for playing instrument samples at different pitches (by
clicking on the 'piano keyboard' display or typing on the computer
keyboard)
* Powerful cut/copy/paste operation (see "Overwrite Options" from the "Edit"
submenu) including mixing operations.
* Editing of stereo samples as either a single entity or as two separate
channels.
* Amplitude envelope, stereo effect envelope, and pitch bend facilities
* Buffered playback system minimises the amount of memory 'lost' to
module area fragmentation (a major disadvantage of most other sound
editing/playback software)
Modifications
=============
This demo version has been specially modified in the following ways:
* Some features have been disabled, most notably recording and file saving
* A splash screen is shown for 5 seconds on start up to remind users that
this is a demo version
* A separate utility is supplied with the release version for setting
sound system configuration, and for playing samples directly from disc.
The utility is not supplied with this demo.
Using the program
=================
The program works much like any other RISC OS application. Here are some
hints and tips to help you get to grips with it.
At the top of each sample window is a tool bar with icons similar to the
buttons on a tape recorder - stop, pause, play, record. These all work just
as you would expect them to work if they were on a tape recorder.
(You can open the Spectrum and Oscilloscope windows (from the icon bar menu)
to "see" the samples playing. Note that these windows can be full-sized (by
clicking on the icon in the top right corner of the window) to double the
display size, though this will slow down the update rate)
To the right of these icons is an auto-repeat button. Samples may include
a repeat loop, (which is shown as a grey background behind the sample
display). Normally, when you play the sample it is played once from start to
finish.
However, if you click the auto-repeat button on, the repeat loop (or the
selection, if there is one) will be included in playback (which will now not
cease until you click the stop button).
To the right of the auto-repeat button is a progress display (usually blank)
which will show
* Samples selected, during a selection drag operation
* Progress (percentage-completed) of any effect you are applying
The main portion of the window is the sample display. Click MENU here to
pop up the main menu, or you can select a portion of the sample by dragging
with select (or adjust). A single select click will deselect the selection and
place a selection cursor instead, while a shift-click will select the
entire sound sample.
Explore the menu. Points to note are:
* When pasting at the selection cursor, pasted data is inserted. If there
is a selection, then the selection will be overwritten by the clipboard
contents - note that overwrite-paste can be used to mix over rather than
obliterate the selection - see the "overwrite options" dialogue box
(available from the "Edit" submenu)
* Dragging a sample file into a sample window will have the same effect as
if you were pasting that file from the clipboard. The clipboard is wiped
by this operation.
* The clipboard (if any) can be shown and edited like any other
sample - On the "Edit" submenu there is a 'show clipboard' option.
The clipboard can also be wiped to save memory if you no longer need it.
* On the "Display" menu, Dots/Lines/Bars/Outline give different display
formats (try them and see!), While "Zoom In" will Scale the view so
that the selected region of the sample fills the window.
* The "Envelope.." effect supplies an envelope editor - you can edit these
by clicking/dragging select to place new points, and shift-clicking to
delete existing points. Once happy with the shape of the envelope, you
can apply it to alter amplitude, stereo position, or pitch in relation
to the envelope shape. Amplitude/stereo-position envelopes can also be
applied repeatedly at a given frequency, to generate vibrato effects, etc.
Some example envelopes, along with a text file describing them, are
included in the 'Envelopes' directory.
* The "Alter" window ("Alter" from the iconbar menu, or from the
"Utilities" submenu of the main menu) can be used to change the sample
format and playback rate (even DURING playback).
* Bring up the preferences, ("Preferences", from the icon-bar menu).
This shows a sequence of icons, each a preference category - click the
category of your choice to edit the preferences...
NOTE that you will need to copy !AudioDemo onto your own disc, and run it
from there if you wish to save the preference options (which is necessary
for the following case...)
Display
Choose "Outline font", click OK, and then save the preferences by
clicking "Save" in the main preference window. Now quit AudioWorks
and re-run it, and so long as the font "Trinity.Medium" is available,
your windows should all look much nicer. (Note that due to the way
in which the WIMP works, it is currently not feasible to have outline
fonts in window titlebars). Experts may also like to try editing
the file "!AudioDemo.!Run" to change the font names and size used.
NOTES
=====
* Some of the supplied samples in '$.ProfSample' are large, and will only
be loadable on machines with at least 4MB of memory. Even on 4MB
machines, it may be necessary for you to quit all other applications and
put all available memory into the Task Display's "Next" slot in order to
load the larger samples. Smaller versions optimised for standard systems
are available in the 'DemoSample' directory.
* Due to the way in which the RISC OS sound system works, it is not
advisable to use several sound-using applications together at once.
AudioWorks goes to considerable lengths to ensure that everything works
OK, but other programs can crash or behave strangely if any other
application tries to use the sound system in a non-standard manner.
