===Support for the LV2 plugin architecture===
 
 
LV2 is a more advanced evolution of the {{external|[http://www.ladspa.org/ LADSPA]}} plug-in architecture and is of strategic importance to Audacity. As well as allowing plug-ins to be categorised, supporting LV2 in the way I propose will make several LV2 synths available as powerful new tone generators.

These GridSizers are an enabling step for a much cleaner design for the largest class in Audacity, the TrackPanel.  The monolithic nature of the existing class has acted as a log-jam to GUI development since at least 2003.  In addition work on wxAUI should facilitate an easier update to improved (modern) toolbars.

===On Demand/Level of Detail File Loading===
 
 
Will provide near-instant loading of PCM uncompressed files: the waveform image is built  while you play or edit, viewable anywhere on demand. An embedded progress bar gives user feedback, plus block-boundary information in debug builds. This facilitates a future move from batch mode to real-time processing which (as necessary for Audacity) can yet degrade gracefully to batch on low-powered machines.

=== Sticky Labels & Multiple Selection of Labels===
 
The limitation that labels do not stick to the audio track and move and edit with them is the most consistent criticism of Audacity Label Tracks.  This project will fix this.  In addition the provision of multiple label selection (with ability to apply an effect to all selected labels) will enable a smoother workflow when working with labels.

André Pinto

Bugfixing, help-generation script, auto-volume determination

This project is primarily a ‘BugFix Superstar’ application where I commit myself to help Audacity team to fulfill its main objective, reach a stable state for 1.4 release. Being myself an Audacity user as a DJ and producer I propose to create a new simple and useful feature for automatic volume detection during a record session. I will also work on User Interface improvements. To meet community needs I've included on my GSoC project the creation of a solution for problems in generation of the zipped manual.

Help-file extraction log overlaying a sample help page
  • Mentored by: Martyn Shaw
  • Idea: Adapted from idea on list.
  • Mid Term Spin Off: 3 ‘P1 or P2 issues’ fixed; 7 ‘P3 to P5 issues’ fixed. Script to generate help zip file client side so that release is no longer blocked on help.

Bugfixing, scripting and find-notes improvements

Audacity is currently focused on the next stable release, so bug-fixing and tools to aid release are priorities. I intend to:

  • Fix a selection of the problems from the release checklist
  • Further develop the currently experimental scripting support
  • Work towards completing the 'Find Notes' feature by improving the related code

These enhancements should help the project move faster towards the next release and beyond.

mod-script-pipe.dll running a perl script to drive Audacity
  • Mentored by: Michael Chinen
  • Idea: Adapted from idea on list.
  • Mid Term Spin Off: (at least) Windows dll that allows a perl script to control import and export of wav files and apply effects. Problems with dialogs crashing non-GUI thread solved. Several linux-specific bugs solved.
