- !Landing
-
- (c) January 1992, Dirk-Willem van Gulik
- {!index Introduction}
- This silly thing will play a {ësound sample}
- recorded during the landing of the space
- shuttle. It was recorded on an Apple
- Macintosh. Just {ëDoubleClick} with {ëselect}
- on the {ëapplication}. It will terminate
- after playing the {ësample}.
-
- The programme sets up he voices, tuning
- and timing needed, and starts the sound.
-
- After that it will take about 15 seconds
- to play the sample during which you can
- preform any other (boot) activities.
-
- Finally {ëpoll-idlle} will promt the
- programme to quit and release the memory
- used. As the voice module is quite large
- this is a neccessity rather than luxery.
-
- {!index The Reasons Why..} The GRAND reason why...
-
- I've created the thing to liven up my
- boot- <Yuk, this sounds like and {ëMSDom}
- sequence>, hence the {ëPollIdlle}.....
-
- {!index The (c) claim...} Feel free to copy. modify, or rape this
- programme as long as the original !Help
- file, the (c) claims and the original
- !Help-message data are supplied along.
-
- {!index Important, read this} The author loves to receive feedback,
- {ëapplepies} and {ëchrismascards}.

- {<sound sample}{<sample}
- {!index - Samples}* Sound Samples...
-
- Soundsamples generally come in various tastes,
- however the can be described as a long list
- of values, representing a certain 'volume'
- which is send to the sound system.
-
- This is done very quickly, several thousands
- of values a second. As these values tend to
- change quickly, so does the 'volume' of your
- speaker. i.e. the speaker starts vibrating.
-
- The trick is of course to control this 'vi-
- bration'. This is very similar to what is done
- on a record. The tiny grooves contain small
- vibrations which are send, grossly enlarged,
- to the speaker.
-
- A regular vibration, a 'sine wave' shaped
- variation for example send to the speaker
- at sufficient speed, will be heard as a
- tone. The shape often inherits a lot from
- the machine which made the sound. A piano
- snare will give lovely shaped flowing
- waves, like small or large waves in a quiet
- pond. A 'sreek', for example a piese of chalk
- on the blackbord making that well known terible
- noice has a mush more violent charactar, sharp
- peaks quickly rising up, disturbing the
- lovely shape.
-
- Suppose a groove on a record, like this one,
- imagine it to be a continious curve :
-
- __ ____ __--__
- -_-- --_-_--- -- ----
-
- This can be translated into numerical data,
- quatisized.. like this,
-
- 3 __ ____ __--__
- 2 -_-- --_-_--- -- ----
- 1
- 212233221212223333223344332222
-
- This is often, althoug not exactly correctly,
- called 'digitalizing' a analoque signal.
-
- In a computer the 2122...22 sequece is often
- called a sample. It is stored digitally along
- with some other data telling the player-
- programme about the speed, time, and
- quatisizing method.
-
- The player programme simply sends the values to
- a digital to analoque converter. Each number
- is translated to a voltage. This rapidly varing
- voltage is the audio signal.
-
- In this {ëapplication} the 'module' contains
- both the sample data, the long strings of
- values send to the speaker and the player
- programme which knows how to send the string
- of values, and at what speed.

- * Mouse oparations.
-
- Really. I've to refer you to the welcome
- quide for all this, and I do not understand
- how you've got here in the first place..
-
- However, just to be on the safe side..
-
- The mouse has three buttons, called, from
- left to right, SELECT, MENU, and ADJUST.
-
- Pressing a button is called Clicking, pressing
- it twice, very quicly, whilst not moving the
- mouse, a major feat!, is called double clicking.

- {<application}{!index - About applications}
- * Applications.....
-
- An application is a programme.
-
- It appears in the 'filer' window as a little
- picture, a landing shuttle this time, with
- a name, preceeded by a pling underneath.
-
- You can run an application by {ëDoubleClick}-
- ing with {ëselect} on it.
-
- You can ask help by pressing {ëMenu} over it,
- and moving to the second leaf menu, from the
- top, with the 'Help' item appearing at the
- bottom of the list.
-
- The application lives in a directory along
- with its frieds, special files with well-
- defined names. You can open the directory
- by {ëDoubleClick}ing with {ëselect} on it
- whilst holding the SHIFT key.

- * {<poll-idlle}{êPollIdlle}{!index - Poll_Idlle}
-
- This is a technical term, see page 1148 of
- the advanced reference manual.
-
- All it means is that the application asks
- as little processor time as possible during
- its live.

-
- Do not you love them !!
-
- Here is what you need.
- - a spare afternoon
- - NO computer
- - 2 apples, grannies will do.
- - 300 gram of flour.
- - 200 gram of butter, margerine.
- - 100 gram of brown sugar.
- This is for a SMALLish pie, multiply the last
- four items, but not the first two by any
- 'real' number you like.
-
- Mix the last three ingredients well. Add a
- wee but of salt and perhaps a bit of
- lemon(scrapings). Put a fifth of this smooth
- paste apart and spread the big lump thinly
- in a pie-tin, (or any other shape...)
-
- Slice the apples into tiny bits, thins slices
- look best. Add plenty of raizins, a bit of
- sugar, lemonjuice, and canel. Mix well. Make
- sure it is not toooo wet.
-
- Throw this in the pie tin. Use the remainder
- of the paste to make a nice netting, or any
- other covering, and spread this over the
- apple/raizin mix.
-
- Put all this into the oven, 4-6 , wait for
- about 45 minutes. Heat up some apricot jam,
- when it starts melting, pour it out over the
- cake. Add a bit of fresh clotted cream with
- lots of sugar, just before serving....
