Code going into 2.1.1

This is a notes page to help us in preparing the announcement for 2.1.1. It might also help with highlighting areas needing more test focus.


Headline Features

  • Much much faster with larger projects, thanks to a faster method for storing the autorecovery file. [Leland]
  • Scrubbing (link to the manual for details), including backwards play. [Paul]
  • Quick-Play from timeline enhancements Timeline, particularly for looping. [Steve]
  • More VI usability enhancements, track focus & navigation [David Bailes]
  • Built in effects now support presets.
  • Can now add/remove effects from Generate and Effects menus [James Crook].
  • Upgraded to Nyquist 3.0.9 (Bugfixes) + Many Nyquist enhancements.
  • Updated LV2 libs (Bugfixes, GUIs on Linux). Support for LV2 factory Presets.
  • Updated FLAC lib (Bugfixes)
  • Crash report integration

The list above has the bug numbers input by hand. This query by Gale bugs fixed for 2.1.1 automatically gives fixes done since 29th March. Bugzilla reports in wiki can probably do this too, but I've some more experiments to do to find out how.


These are some bug fixes that never made it into bug numbers:

  • ---: Parameters that weren't configurable in chains now fixed.
  • ---: Meter refresh flicker fixed
  • ---: Meter refresh rate update fixed
  • ---: memory leaks and orphans
  • ---: memory leak in noise reduction
  • ---: hyphenated bit rates in Export dialogs

(Probably) Not reported on

Below the Fold

Notes that are relevant to next release.
WIBN= "Wouldn't It Be Nice".

Developer WIBN lists are list of things they are actively looking at. QA/Support WIBN lists are lists of things they are lobbying for. These are aspirational changes. The closer we get to June the less likely the ones still listed in this section are to be in.

James' WIBN List

  • 276 [P2] Repeatedly start/stopping Pulse Audio. A fix by keeping the audio card open. Also means monitoring persists.
  • 673 [P2] Installer language does not carry through to executable. Even if done for 2.1.1 we will not have inno in all Audacity languages for 2.1.1.
  • Diags - Glitch detection (counting) of overruns and underruns.
  • Diags - Command line options, and run very simple test, e.g. generate DTMF from Travis build to get us started on automated test.
  • Diags - mod-diag as built-in module. Also to help get built-in modules working for other reasons.
  • Diags - mod-diag actually with a GUI window so we can see diags and reset them live.
  • Diags - Automatically generate screenshot for each effects dialog.

James' Notes

  • We will not be supporting wx3 with 2.1.1 and that needs to be clear in the announcement.
  • The shift to binary in autorecovery is potentially a little dangerous. We need to review whether there are integrity (part written) file issues, which would affect us if there are large histories. Possibly needs a checksum on the end to guard against that? Possibly useful test is with a deliberately corrupted auto recovery file, and see what happens.
  • The shift to built-in effects using the new RT code is potentially dangerous. Possible issues include these effects offering (broken) RT preview, parameters from Chirp appearing in ToneGen (they share the same code). EQ and Noise Reduction possibly the most likely to have problems, as they have non-standard parameters.

General News/Activity

  • Google code going read-only in August.
  • Debian Jessie on 25th April, with wx3.
  • Alexandre Prokoudine Interview on future of Audacity, 17th April.
  • Viktor working on (LADSPA?) percussion/harmonic separation effect.
  • Trademark etc discussions with Dominic.
  • Discussions with Sourceforge and FossHub.

Enabled / Disabled

This is current status/plan:

  • Scientific Filter out (could be OK as part of a module)
  • WDM-KS out (considering a module, but not for 2.1.1. needs work on test support)
  • Spectral Selection in (OFF by default)
  • Module prefs in (It needs work for this to be OK)
  • MIDI_OUT out.
  • Scrubbing in (Needs more work to be OK).
  • Crash Report in.
  • wx3 out. Warning dialog if compiled with it.


P1/P2 Bugs Outstanding right now (live table)

no bugzilla tickets were found


Steve's WIBN List

  • 683: Excessive amplification causes NaNs.

Buanzo WIBN List

  • Bugzilla_report, Maths and SoundManager2Button Extensions to wiki.

Vaughan WIBN List

  • Updated Logo/Text (via Chris F).

Paul/Leland WIBN List

  • Enhanced NumericTextControl + Slider combination in ShuttleGUI.

Paul WIBN List

  • Color tweaks on spectral selection.
  • Small speed ups on spectrogram enabling a new 'spectral refinement' feature that gives crisper spectrograms. This option is particularly suitable for voice work.

Luciano#s WIBN List

  • Customisable spectral colours.

Peter's WIBN list

2.1.2

These are things identified in 2.1.1 that might be in 2.1.2.

  • Configurable Mouse Prefs.
  • Far fewer binding prefs set up by default. The most common high value ones only. Instead use import for a fully populated list, if desired. Power users (the people who use all the shortcuts) will typically set up their own.
  • MultiButtons

Demos/Experiments

  • Leland's analyze effects whilst recording.
