What is a music production tool-chain ? Songwriting Recording Mixing Mastering Distribution Promotion Statistics Backup

Why new tools?
We want:
Automated tasks
Deterministic and precise processes
Processing power handling high quality audio
Low costs on software
Integrated software with existing applications
=> Software constraints: Free, Simple, Precise, Automated, Extensible, Can be integrated easily

Why new tools?
Existing music software:
Very costly
Lacks precision and determinism
Big complex integrated frameworks
Automation and plug-ins use proprietary protocols
Rarely handles high quality audio
My specifications:
Free => Open Source
Simple => Several independent tools
Easy integration => Command line interface
Automated/Customizable => Configuration files

Why new tools?
Why Ruby?
Easy to implement and test quickly
Easy to interface with C for performance
No need for complex GUI
Quality libraries handling most of the work needed

Recording, Mixing, Mastering
Transform and analyze audio files (remove noise, strip silence, compress, DC offset, synch, mix, amplify, Fourier profile. ..) => Wave Swiss Knife
1 task = 1 plug-in
Simple command line parameters
C libraries for performance
Handles any type of Wave file
http://waveswissknife.sourceforge.net

Analyze recordings, organize and automate tasks during mixing and mastering, and deliver files with proper formats => Music Master
Handles all processes from recording to producing distribution ready audio files
Uses Wave Swiss Knife
Can be used to produce complete albums
Recording, Mixing, Mastering http://musicmaster.sourceforge.net

Distribution
Distribute on a dedicated website => Ruby on Rails
Handle user accounts
Provide shopping carts
Deliver multimedia content
Integrate external forums, blogs, chats, podcast
AJAX compliant
http://rubyonrails.org/

Statistics
Get statistics from many websites: web-scraping, consolidation in a database => Stats Collect
Display statistics => Ruby on Rails
http://statscollect.sourceforge.net
Easily extensible: 1 plug-in per web source
Handle batches of collections orders

Organize files to easily work and use tools to backup, clean up generated or temporary ones, and keep track of files dependencies => FSCMS conventions + toolbox
Conventions can be used without toolbox
Extensible using plug-ins for processes
Handles files generation mechanisms
Songwriting and backup http://fscms.sourceforge.net

What next ?
Contributors welcome! (testers, developers, writers...)
Write tests to get out of Beta status
Port WSK on many platforms
Finish FSCMS toolbox
Complete documentation
Create a generic Rails platform for users maintaining and tracking their social networks (synchronization, statistics...)
Create Rails gems for complete AJAX handling and external websites integration
