Developer News

21 January 2013
 * Audacity 2.0.3 was released on 21 January. This release introduces the fast, high quality libsoxr resampling library which is enabled instead of the previous libresample for all releases. Libsoxr is also the default when compiling Audacity. Significant improvements were also made to Time Tracks and we would welcome feedback on how well libsoxr's var-rate resampling works with Time Tracks.

24 August 2012 29 June 2012
 * Audacity 2.0.2 was released on 24 August. This is mostly a bug-fix and stability release, with a few improvements as well. Two features ("Audio cache" which used RAM for audio data and FFmpeg "On-Demand") have been removed for now so they can be improved. Modules can now be individually enabled and disabled in Preferences, as a step to making these more mainstream.
 * Audacity 2.0.1 was released on 29th June to supersede 2.0.0. There is a good balance of new features (including keyboard shortcuts for effects) and bug-fixes (in accordance with our quality requirement that each new release in the 2.0 series will be "never less good overall than the standard set by 2.0.0").

13 March 2012
 * Audacity 2.0.0 was released on 13th March as "no longer Beta" after extensive testing and some final bug fixing for WAV, AIFF and MP3 issues. Going forward, the developers plan single series of releases rather than simultaneous stable and Beta versions. Some headline issues remain to be addressed, notably handling of large projects and identifying rare moonphase data integrity problems.

11 December 2011
 * Audacity 1.3.14 Beta was released on 11th December. Much work has been done by Vaughan, Martyn and others on Bug 451 to prevent overlong block files being produced or deleted. It is hoped that some reports of Bug 137 were in fact bug 451, so these will now be fixed. Please report any issues found in 1.3.14 when reopening saved projects.

11 April 2011
 * Audacity 1.3.13 Beta was released on 11th April after a year of intensive bug tracking and fixing. Bug 137 remains a stumbling block requiring careful investigation. Help finding scenarios that make this bug reproduce will be most welcomed.

 07 July 2010
 * Marco Diego Aurélio Mesquita makes improvements to the noise removal effect, fixing a regression that affected attack/decay times, adding a sensitivity slider that helps with tracks with higher levels of noise and adding the option to isolate the noise rather than remove it.

04 July 2010
 * Vaughan makes important fixes to autorecovery, tested by Gale and Michael. Understandably this is functionality that it is mission-critical and if we have it at all needs to work reliably.

 14 May 2010
 * Martyn starts on some enhancements to EQ curves, making it possible to import/export predefined EQ curves.

02 April 2010
 * Audacity 1.3.12 Beta was finally released on 1st April. It was aborted in March due to insufficient time to resolve and test issues that arose in the Windows build. 1.3.12 does not have the redesigned linking code enabled yet. Even with linking off, labels in advance of a cut or delete can now shift if the label track is selected.

14 February 2010
 * Bug tracking moved to Bugzilla with effect from February 2010. The former Release Checklist would have needed a custom-developed solution to efficiently track large volumes of bugs.

10 February 2010
 * The details of how to do label linking are discussed taking account of both underlying functions and crucially user interface too. As a result a much cleaner approach to what we currently have is proposed, and the fact that labels themselves are a side issue here becomes clear.

25 January 2010
 * Switch over from CVS on sourceforge to SVN on google-code complete. E-mail archive of commit messages at google groups, also history of changes.  Significant speed improvement for downloads, more stable infrastructure and nice web-based code browser.  Cool.

 20 January 2010
 * Audacity 1.3.12 Beta release planned for 1st March with a double freeze from the 22nd Feb. This will not include new features, but should incorporate fixes to more bugs, small usability improvements and may benefit from some changes resulting from code reviews.

18 January 2010
 * Audacity 1.3.11 Beta released. Essentially a maintenance release to fix bugs reported since 1.3.10, notably a problem exporting partial selections.

11 December 2009
 * Some new ideas for GSoC 2010 have been posted. Planning for a possible GSoC 2010 begins.

10 December 2009
 * 'Marty' Goddard given temporary CVS write access for agreed check-in of new mod-script-pipe commands he has developed.

01 December 2009
 * Audacity 1.3.10 Beta released. This has numerous small improvements and fixes to bugs.  It's also the first version to have the new much improved html manual.

28 Nov 2009
 * Al Dimond given CVS write access after discussion in the technical council.

27 Nov 2009
 * Experimental bugzilla installation set up. We're considering moving the Release Checklist to this as a proper bug tracker, if we feel it will make our life easier.  Otherwise not.  Quite a lot of details still to be worked out.  In particular we want to be able to more easily produce release notes (P3 and higher issues) and the text for release notes is significantly different from what we use for issue titles.

01 September 2009
 * Our GSoC 2009 projects come to a successful conclusion with both students passing, and the bug fixes worked on by the students are released in a new 1.3.9 Beta version. As a result of GSoC, we now have a firmer base for the final push towards a stable 2.0 Release, plus:
 * the ability to once again build Help into the program
 * the basis of Perl Scripting support
 * an experimental pre-record level detection feature to be included in a future Audacity version.

26 April 2009
 * We have two GSoC projects and students for 2009. Both projects involve bugfixing which will help us to get to a stable release.  Both provide a 'big win' (read large return on effort invested) spin off by the mid term.  In one case that means we will have help, which was previously blocking a stable release.  In the other it means we will have scripting support from Perl.  As well as these changes both projects also have some enhancements which will be worked on mainly in the second half.

7 September 2008
 * Four of our GSoC 2008 students passed their evaluations and will now receive their final stipend from Google and a certificate of completion (not to mention that coveted GSoC T-Shirt...). Congratulations to all our students for the code they contributed to improve Audacity, and thanks to everyone who worked so hard on mentoring and administration. We hope all our student participants will continue their involvement with Audacity in future.
 * We're now getting to work consolidating and evaluating the new GSoC features for inclusion in the next 1.3.6 Beta. Depending on feedback from 1.3.6 and (crucially) on available resources, we can then identify any GSoC features that are safe and complete enough for the 1.3.7 Release Candidate for 1.4.0 Stable. GSoC features omitted in 1.4.0 will be available again in Beta 1.5.0 and further developed.
 * Don't forget, we're happy to try and help if you're trying to compile Audacity and having problems getting the instructions to work. Michael and Paul Livesey recently helped a couple of users with compiling on Mac. Meantime Martyn who normally develops on Windows was trying his hand compiling Audacity against wxWidgets 2.8.8 on an  Eee PC running Linux!
