Hi,
I want to write a quick-and-dirty application to help me learn songs.
I don't want to spend 10 years writing the app and not learning the
songs, so I am hoping one of you knowledgeable folks can point me in
the right direction.
The sales pitch description of the application is this:
Loads QT content and allows you to set in/out points and loop over the
selection. Also slows it down without changing pitch. Other than
filesystem navigation etc., all important commands are done by
keyboard OR MIDI FOOTPEDAL.
A more detailed outline of what I think I might need to do to make it
so is:
Here is an initial swag at some software requirements:
Basic
open and play quicktime content from disk, youtube, random urls,
playlist
client/server controllers for
transport control (play, pause, stop, ff, rw, etc.)
media control (volume, eq, contrast/brightness, etc.)
make/read/update location markers in media
loop (auto-loop when outpoint is set)
slow down it
Better
midi controller mapping/editor
subloops?
extend endpoint of loop
name/save sections
video: zoom in, enhance image (contrast/bright?)
audio waveform
Awesome
auto-section based on content analysis
Would anyone here be able to help me wade through the huge amorphous
mass of Apple docs and examples to decide what I need to look at/learn/
copy?
I'm thinking that I can get most of "Basic" done using QTKit, while I
might have to wrap CoreAudio in Objective-C++ to get AUTimePitch into
the situation? (and how to keep audio/video in sync when slowing and
slowed?)
I eagerly await the flood of your knowledge! :-)
Seriously - thanks really really much for any direction you can give
me. Even if it's "download App <x>, it already does all that".
Regards,
Chris
