Changes in version 1.3.5 Recording / Playback: * Several bugs fixed so that latency correction should be better, and more devices work correctly. Problems with invalid sample rates under Linux should be much rarer. * Newer version of Portaudio library. * New feature to record onto the end of an existing track (hold Shift while clicking Record). Import / Export: * Updated versions of Libogg, Libvorbis, Libflac, Libsndfile and Twolame libraries. * Handling of unsupported file formats more informative. * Handling of file names with slashes on OS X improved. New dialog allows replacement of illegal file name characters on all platforms. Interface: * Improved scaling and layout for rulers and VU meters. * Envelope fixes/improvements including full control of undo/redo. * New keyboard shortcuts and improved menu navigation. * Preferences: More intuitive tab arrangement. New options for mute/solo and Metadata Editor behavior. Language can now be changed without restart. * Expanded Build Information tab. Effects: * New Vocal Remover plug-in, improvements for Generate effects. Compilation: * Fixes when building Audacity with libraries disabled. * Improvements to make Mac and Solaris builds easier. Security: * Full fix for issue CVE-2007-6061 on systems where temporary directories can be changed by other users (thanks to Michael Schwendt). Miscellaneous: * Updated translations for many locales. * Several stability improvements. -------------------------------------------------------------------------------- 3. Known Issues Please also check: http://audacityteam.org/wiki/index.php?title=Known_Issues for details of any issues that have been identified after release of this version. * If Audacity is built from CVS with wxWidgets 2.6.4 or later, the Escape key does not cancel most dialogs. This is due to a wxWidgets bug. In builds provided by the Audacity project, wx 2.6.4 has been patched. This means that all dialogs can be cancelled by Escape when first opened, but in Preferences and Effect dialogs, keyboard users must now tab twice to reach the first field of the dialog. Additionally, for Preferences, GVerb, Hard Limiter, SC4 and user-added LADSPA/VST effects, once the user interacts with the dialog, it cannot then be cancelled by Escape without first tabbing to the OK or Cancel buttons. * Export Multiple fails with no export or warning if an empty label is encountered. * The preference "Hold recorded data in memory until recording is stopped" is misnamed. It caches most audio data for the duration of the session, including project data and imported files. Enabling it may cause a crash when making long recordings or opening large files or projects. * A few interface elements do not change language without restart. * Calculation of "disk space remains for recording (time)" is incorrect when recording in 24 bit quality. You may record for 50% longer than the indicated time. * Pressing Play (but not spacebar) in a second project when another is already playing stops playback of the first project. * Projects created by Audacity 1.1.x may open incorrectly. * Metadata such as ID3 tags is not fully imported and exported for all supported file formats. MP3 tags *are* correctly imported and exported to the current ID3 specification, but some players don't fully support this specification, so may not see all the tags. * No warning is given if File > Save or File > Save Project As... is carried out with no tracks open. * Not all menu items are correctly enabled when the preference: "Select all audio in project, if none selected" is checked. * Beep on completing long process may not be audible on many systems. * Audacity can import and display MIDI files, but they cannot be played or edited. * Windows only: Welcome Message: On some systems/browsers, links are not brought to top, and some screen readers that otherwise work well with Audacity cannot read its text. * Windows (reported on): There have been reports of clicks during recording on some Windows XP systems using Audacity 1.3.4, where 1.2.6 had no problem. It is not clear if 1.3.5 will have this issue or if it will occur on other operating systems. Users can help us by sending any reports of this problem to: audacity-devel@lists.sourceforge.net * Windows only: Audacity is incompatible with some professional sound cards and may crash if one of these cards is the default when you open Audacity. As a workaround, make a different sound card your default when using Audacity, but please let us know if this affects you so that we can track down and solve the problem. * Mac OS X only: Some users find that after running Audacity other media players don't produce any sound or crash. Audacity tries to select the best quality settings your system is capable of, to give the best recordings possible. Some sound drivers also retain these settings as defaults for other applications, which can cause these symptoms To get round this, enable the option "Do not modify audio device settings" on the Audio I/O tab of the preferences, and make sure that your sound device is set up (in the Apple Sound and Midi Setup utility) to work in stereo, 16bits, with a sample rate of 44100Hz or 48000Hz. More help at: http://audacityteam.org/wiki/index.php?title=Mac_Bugs#Loss_of_sound_after_running_Audacity * Mac OS X only: Portable settings aren't picked up, and the default settings (in the default location) are always used. See this page for a workround: http://audacityteam.org/wiki/index.php?title=Portable_Audacity * Linux only: Audacity now supports interfacing with Jack, however this has not been tested, and is known to have a number of issues with both reliability and useability. Patches to improve both will be welcomed. * Linux (reported on): The first file imported into a project no longer changes the project rate to the file's rate, if that rate is absent from the project rate list. * Linux (Debian-derived) only: Audacity configure script does not detect libsoundtouch on the system and so Change Pitch and Change Tempo effects are disabled. This is a debian bug (#476699), which can be worked around by symlinking /usr/lib/pkgconfig/soundtouch-1.0.pc to /usr/lib/pkgconfig/libSoundTouch.pc. Also note that the Windows installer will not replace 1.2.x installations, but will install alongside them. -------------------------------------------------------------------------------- 4.
