Audacity for Windows 1.3.11 Beta


#3

Audacity 1.3.13 (Beta)

Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
Generating inside a clip could modify the clip length or create spurious clips.
Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a “1” appended to the track name.
Edit > Region Save did not save the cursor position.
(Windows) Projects crashed when clicking rapidly inside the interface or when applying repeated effects towards the end of audio tracks.
(Windows) Some Unicode characters could not be typed into labels,or caused a freeze using some input methods.
(OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.
Imports and Exports:
Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
Variable bit rate MP3s exported using “MP3 Files” were larger than necessary because using the bit reservoir was disabled.
(OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error “reference to invalid character number” will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).
Other bug fixes:
Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
(Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
(OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.
(Linux) Recordings made with the pulse device crashed or stalled when using overdub and/or software playthrough.
(Linux) Play-at-Speed crashed at 0.08 speed or lower if Audacity was configured with libsamplerate.
Changes and improvements:
Control Toolbar renamed to Transport Toolbar.
Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
New “Sync-Lock Tracks” feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
Equalization: New “Manage Curves” dialog for importing and exporting curves.
Noise Removal: New “Sensitivity” slider to adjust the noise threshold, and new option to isolate noise.
New “Extended Import” Preferences for specifying different importers to open specific file extensions.
Improved Automatic Crash Recovery with all project changes autosaved.
MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
(Windows and Linux) The window Close button and other system close or shutdown commands now quit on closing the last window. File > Close now always clears to a new, empty project.
(OS X) Simpler installer with top-level “Audacity” folder.


#6

Changes in Audacity 1.3.14

Bug fixes for:
Interface:
Excessive delay occurred when typing into labels in long projects.
Last digit of TimeText controls could not be manipulated in some formats.
(Windows, OS X) Play and Record shortcuts did not work after clicking in Device Toolbar.
(OS X, Linux) Crash occurred if Toolbars were reset during playback or recording.
Imports and Exports:
MP2 files were not importable without FFmpeg library or an import rule.
Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.
Effects and Analysis:
An empty command could be added to a Chain which then displayed a Nyquist error message when run.
Plot Spectrum didn’t preserve signal level if multiple tracks were analyzed.
Other bug fixes:
Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but “orphaned”, so will appear as silence.
Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
Fixed some crashes and incorrect movement of audio when dragging tracks.
(Windows) Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.
(Linux) Restore building if USE_PORTMIXER is not defined.
Changes and Improvements:
Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process stereo channels independently.
Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
Mix and Render now preserves clip length by not rendering white space between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
Grouped some Edit Menu items into “Remove Audio” and “Clip Boundaries”.
CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).
(OS X) Added support for AudioUnit MusicEffects (but no MIDI support).
(Linux) Set the per-user files directory per the program name set in configure.
(Linux) Changed the default location of the Audacity temporary directory to be in /var/tmp not /tmp, so preserving the directory between reboots.

Please be aware of Known Issues at Release (also viewable in the included README.txt).


#7

[B]Audacity 2.0 released
[/B]
Bug fixes
Interface

Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
(Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another. 

Imports and Exports

Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
(Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x. 

Effects and Analysis

Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
Fixed Plot Spectrum background could be transparent on some machines.
Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
Chirp, Tone and Silence generators now remember their settings. 

Other miscellaneous bug fixes
Changes and Improvements

New Interface preference to show the track name in the display (this is off by default).
Longer default Playback preference for effects preview and preview before cut.
Restored use of Page Up and Page Down to scroll horizontally.

[B]Interface [/B]

[ul]
[li] Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
[/li][li] Finding zero crossings could cause the selection to expand into white space at either side of the clip.
[/li][li] Clips did not drag to another track if mouse was over a selection.
[/li][li] Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
[/li][/ul]
[B]Imports, Exports and Files[/B]

[ul]
[li] Exporting to WAV or AIFF led to a “Libsndfile says” error or corrupted output due to order of metadata in imported files.
[/li][li] (Mac) Fixed crashes importing MP3 files on PPC machines.
[/li][li] (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
[/li][/ul]

[B]Effects and Analysis[/B]

[ul]
[li] Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to “read-directly” WAV and AIFF files before On-Demand completed.
[/li][li] Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
[/li][/ul]

[B]Other miscellaneous bug fixes[/B]

[ul]
[li] fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.
[/li][/ul]

[B]Large Projects[/B]

[ul]
[li] Projects with more than 2^31 samples (just over 13.5 hours at 44100 Hz) will not re-open correctly. [*] Higher sample rates mean proportionally shorter times - so just over 6 hours at 96,000 Hz. We know the cause, and do intend to address this bug. Workaround: Before saving or closing the project, export to audio files of appropriate size, or cut and paste sections of audio containing less than 2^31 samples to new Audacity projects and save those.
[/li][/ul]

[B]Problems reopening, saving or crashing in projects[/B]
The following problems are very rare, but have the potential for losing data. The developers have not yet been able to reproduce these problems so please write to our feedback address if you encounter any of these symptoms.

[/li][LIST]
[li] The .aup project file was not saved (or incompletely saved, giving a “line number” error).
[/li][li] Audio that was there previously is silenced.
[/li][li] “Missing Audio Data Block File(s)”, “Problems Reading Sequence Tags” or “Orphan Block File(s)” errors are reported. If you see these errors, please choose the options to “Treat missing audio as silence” or “Continue without deleting” the orphans.
[/li][li] [U][B]Note:[/B][/U] To avoid any problems, export a WAV or AIFF file from your project before closing it, then you can import the WAV again if the project becomes damaged.
[/li][/ul][/LIST]

[ul]
[li] [U]When working in the project:[/U]
[/li][LIST]
[li] Errors occur when saving the project or when Audacity autosaves, perhaps wrongly suggesting the disk is full or not writable (if this happens, try exporting the audio as WAV).
[/li][li] Unwanted renaming or moving of .au files within the project.
[/li][li] Multiple or duplicated .aup files or project folders appear within the same project.
[/li][li] Unexplained crashes or corrupted audio occurs (note this can happen if the computer is low on memory or disk space).

Audacity® is free, open source, cross-platform audio software for multi-track recording and editing.

Jan 20th, 2016: Audacity 2.1.2 Released

Audacity 2.1.2 replaces all previous versions.

We’ve made several improvements to the spectrogram view of tracks which are particularly valuable for vocal work. Thanks to Paul Licameli.

New option ‘Spectral Reassignment’. This algorithm deduces a ‘finer’ spectrogram for vocal work.
Improvements to Pitch (EAC) – cleaner (sharper) display.
Spectrogram Settings are now available per-track.

We put a lot of work into upgrading the key wxWidgets library we use from version 2.8.12 to version 3.0.2. This fixes many bugs in Audacity on Linux. Thanks particularly to Martin Steghöfer, Leland Lucius, David Avery.

Because there was so much work involved in moving to wx3 we were unable to make many of the other changes we wanted to make for 2.1.2. Fuller details on the changes since 2.1.1 can be found in the 2.1.2 Release Notes.

This is just FYI for anybody that uses Audacity, (Audacity v2.1.3 RC1 is available.)


#11

2.1.3

Changes since version 2.1.2:

Changes and Improvements:

  • Interface:

  • (macOS) Support for horizontal scroll on Magic Mouse / Trackpad and for Trackpad pinch/expand zoom gesture.

  • Pinned option on waveform so waveform moves and recording/playing head stays still.

  • Timer Record options to save/export/exit after recording.

  • Scrub Ruler and optional Scrub Toolbar.

  • New shortcuts ALT+RIGHT and ALT+LEFT (move to labels without editing).

  • Effects:

  • Effects no longer grayed out when paused.

  • New Distortion effect (replaces Leveller).

  • SBSMS (higher quality but slower) option on Change Tempo / Change Pitch effects.

  • New Rhythm Track generator (replaces Click Track).

  • New Generator for Sample Data Import.

  • Nyquist effects now significantly faster.

  • Other Changes:

  • Upgraded the PortAudio library to v19 rev r1966. This gives Audacity Windows 10 support.

  • (macOS) Audacity.app now has its resources inside it rather than in a separate folder, so installation to /Applications/ is cleaner.

  • (macOS) Audacity 2.1.3 provides partial support for Sierra. Details at http://wiki.audacityteam.org/wiki/Partial_Support_for_Mac_Sierra_in_2.1.3

#12

2.2.2

Changes since version 2.2.1:

Improvements

  • Dropout detection Dropout detection is controlled from a setting in Recording Preferences called “Detect dropouts”. When this setting is “on” (default setting) Audacity will detect dropouts (brief gaps in the recording) and will insert zeroes into the recording to keep the other good parts synchronized. These silent spans will make the dropouts more obvious, but keep the duration of the recording correct. When recording stops, a Warning message box alerts the user and a label track, called “Dropouts”, is added showing the lost parts, labeled with consecutive numbers.
  • Improved horizontal zooming For this release we have improved the way zooming using your mouse wheel works and provided a new Zoom Toggle function.
  • Improved vertical zooming We have added a context menu to the vertical scale to control vertical zooming Previous vertical zooming methods (left-click in the vertical ruler, left-drag in the vertical ruler) remain available by selecting “Advanced Vertical Zooming” in Track Behaviors Preferences.
  • “Extra” menu The “Ext-Bar” and “Ext-Command” menus have been consolidated into the “Extra” menu.
  • Theme tweaks The appearance and/or contrast of a few icons has been improved.
  • Easier access to changing key bindings for shortcuts For menu commands that are enabled (not grayed-out) if you hold the Shift key and click on the sub-menu item, instead of executing the command the Keyboard Preferences pop open at the chosen command. You can then change that (or any other) shortcut binding.
  • Language selection in Preferences Interface Preferences has been upgraded so when selecting languages the proper spelling of these languages is shown with accented and special characters.

Bug Fixes

  • Multiple use of “Save As” to the existing open project can result in data corruption/loss
  • Crash undoing during record, using Discard button of History window
  • Exporting audio in compressed formats to device with insufficient space produces inconsistent/truncated results
  • In Export Multiple, Cancel does not remove the file that is in progress when Cancel is chosen
  • Unicode page encodings fixed ( ° °)
  • Crash using SBSMS pitch change at low sample rate
  • (Mac) Equalization: “Telephone” curve displays a flat line, no sound on Preview
  • Toolbars: open undocked if previously not shown, unless Reset Toolbars first
  • Analysis effects that create labels should give focus to label track
  • Control value may be out of range when using FloatingPointValidator
  • Analysis effects produce false indication that a label is open for editing
  • Import Uncompressed File Dialog Incorrect Reference to Menu Item
  • Wave Color not grayed out in TCP dropdown menu when in Spectrogram view
  • Hover indication on note track channel toggle appears on all tracks (when they rerender)
  • Installer has old logo for 2.2.1 and 2.2.0
