## Usage

* Lecjoa plays the audio file generate with draws
* Lecjoh plays the audio file abadie.joh (4 bytes wavefront High Definition Audio)
* Lecjo plays the audio file abadie.jo
* multidirectional talk : generate a Html document, producing a video that can be controlled in speed in two worlds.
This document is fully generate with imagination. No picture, and no sound of musical instrument or sound recorded.

## concept to realization

* Lecjoa : We create a conversion table for reading data provided by the user. We create conversion tables to draw the wave fronts to avoid calculations. We place the generated audio file in the audio player.
* Lecjo : We create a conversion table for reading data provided by the user. We create conversion tables to draw the wave fronts to avoid calculations. We place the generated audio file in the audio player.
* Lecjoh : We create a conversion table for reading data provided by the user. We generate by calculating the wave fronts. We place the generated audio file in the audio player.
* multidirectional talk : We create a blank html page in multidirectional talk with the pre tags. 
We place dynamic div tags within the document between pre tags. We create buttons to perform the dynamic tags.

## detail construction lecjoa 

* html page called function lecjoa() of js, that retrieves data.
* function lecjoa() call function lecjo() that reads data one by one and calls actiontotale().
* la fonction actiontotale() appelle la fonction fonction lecjo() qui transforme les données en format brut compatible avec les formats audio du moment.

## Construction Example 

* The soundtrack of the example is built using eight identical audio FILES, except for one difference.
Each sound is coming directly from the instrument mark unimaginative just using a spreadsheet.
The idea is to play with two dimensions. The constant and varying the other to each file.
So we vary the length of the wave of falling edge of 25 to 250 per file and we keep the same values in all the columns of the spreadsheet. Only the last column changes. For the last sound, 8 then:
220 100 219 100 218 100 40 200

130 220 129 220 129 220 127 220
For the first sound, just replace the value 200 in the last column by 25., second sound by 50 ...
The construction of acoustic forms is like that of the French language, several dimensions with differents laws in balance. In such as the location of a point or comma, the meaning of the sentence changes, here we change the length of the wave of falling edge, and keep all the rest the same. No algebra, no algorithm, no geometry, no frequency, it is only a resumption of the century concepts of European enlightenment.
