# spectrogram editing tool in a browser
The sub-project is about have an editing tool in a browser
that will allow generating, editing, compacting .spec files
## the idea
We want a web page (html+javascript) capable of:
* loading a .wav file and showing the spectrogram (IDCT_SIZE=512)
* compacting this spectrogram if needed
* generating the .spec file
* allowing some editing on the spectrogram
* and most importantly: allowing the compression of this spectrogram using elementary bricks like bezier-curves (with a large stroke width /
brushes), rectangle, noise addition, etc.
These tools must be available in the web editor (in javascript) as well as
in c++ equivalent too.
The idea is the compress the .wav spectrogram using elementary bricks and
simple representation (as well as being dynamic) during the demo: we
generate the audio on the fly by 'drawing' the spectrograms and passing them
to the synth
## the work
Analyze the requirement for the HTML tool. It must remain simple and easy to
use. Don't over-engineer it.
Still, the tool must have a decent load/save offer, to:
* load the .wav
* save the .spec
* save/export the descriptive compressed version in vectorial form (like the SVG format, in fact)
* be able to load this vectorial form
Then we need a reader for the vectorial form in c++ to use in the demo.
We also need to elementary tools / bricks to: draw a line / bezier curve /
rectangle, ellipse, etc. in frequency domain, to generate the spectrogram on
the flight.
We also need controllable random noise generation to add some 'texture' to
the spectrogram.
## the files
the HTML/JS tool should be under tools/editor
the c++ code should be added to the library under src/audio/
