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

4.
Why new tools? <ul><li>We want: </li><ul><li>Automated tasks

5.
Deterministic and precise processes

6.
Processing power handling high quality audio

7.
Low costs on software

8.
Integrated software with existing applications </li></ul><li>=> Software constraints: Free, Simple, Precise, Automated, Extensible, Can be integrated easily </li></ul>

9.
Why new tools? <ul><li>Existing music software: </li><ul><li>Very costly

10.
Lacks precision and determinism

11.
Big complex integrated frameworks

12.
Automation and plug-ins use proprietary protocols

13.
Rarely handles high quality audio </li></ul><li>My specifications: </li><ul><li>Free => Open Source

14.
Simple => Several independent tools

15.
Easy integration => Command line interface

16.
Automated/Customizable => Configuration files </li></ul></ul>

17.
Why new tools? <ul><li>Why Ruby? </li><ul><li>Easy to implement and test quickly

18.
Easy to interface with C for performance

19.
No need for complex GUI

20.
Quality libraries handling most of the work needed </li></ul></ul>

21.
Recording, Mixing, Mastering <ul><li>Transform and analyze audio files (remove noise, strip silence, compress, DC offset, synch, mix, amplify, Fourier profile. ..) => Wave Swiss Knife </li></ul><ul><li>1 task = 1 plug-in

22.
Simple command line parameters

23.
C libraries for performance

24.
Handles any type of Wave file </li></ul>http://waveswissknife.sourceforge.net

25.
<ul><li>Analyze recordings, organize and automate tasks during mixing and mastering, and deliver files with proper formats => Music Master </li></ul><ul><li>Handles all processes from recording to producing distribution ready audio files

Statistics <ul><li>Get statistics from many websites: web-scraping, consolidation in a database => Stats Collect

34.
Display statistics => Ruby on Rails </li></ul>http://statscollect.sourceforge.net <ul><li>Easily extensible: 1 plug-in per web source

35.
Handle batches of collections orders </li></ul>

36.
<ul><li>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 </li></ul><ul><li>Conventions can be used without toolbox

37.
Extensible using plug-ins for processes

38.
Handles files generation mechanisms </li></ul>Songwriting and backup http://fscms.sourceforge.net
