===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.

FFmpeg is ''the'' standard open source library for audio file conversions. It can be used to greatly expand the range of proprietary formats handled by Audacity.

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.

=== 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 to meet its main objective, fixing bugs so as to reach a stable state for 2.0 release.

Being myself an Audacity user as a DJ and producer I propose to create a new simple and useful feature for pre-record automatic volume detection. 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.

  • 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.


Dan Horgan

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. This project was aimed at:

  • 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

This helps the project move faster towards the next release and beyond.

In the event, work on "Find Notes" was dropped in favour of more bug-fixing and scripting work, as per the mid-term evaluation noted below.

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.





Other Information about the Projects


13th July 2009: Both projects passed the mid term having achieved the mid term goals. This year with a smaller group of students we've not been doing semi-monthly alphas. The need to coordinate changes is less. We are now more focused on a stable release. As a result the project goals for Dan's project have changed with much more being added into the scripting part - to make it useful in testing and in automated screenshot capture - and the planned substantial changes to track painting code being dropped, partly because of concerns about stability risks as we approach a stable release. Andre's project goals have changed less. The aim is to keep the AV code simple rather than risk a more complex interface that might not be completed in the remaining time.

01 September 2009: Both projects passed final evaluation based on the coding done, excellent communication and a general willingness to contribute to our work during the Summer. Overall, GSoC 2009 moved Audacity significantly further towards its goal of a new Stable 2.0 Release towards the end of the year.
