-
- Source code to this program is always available; for more
- information visit our website at:
-
- http://audacity.sourceforge.net/
-
- This program uses wxWindows, a cross-platform GUI toolkit. To
- compile this program, you will need to download wxWindows from:
-
- http://www.wxwindows.org/
-
- To compile on Linux and other Unix systems, simply run:
-
- ./configure
- make
- make install
-
- There are a few options to the configure script. You can
- see them by running "./configure --help".
-
- If you want to do any development, you might want to generate
- dependencies:
-
- make dep
-
- Project files for VC++ on Windows and CodeWarrior for Mac
- are included with the source code. If you are having
- trouble compiling on a non-Unix platform, please email
- audacity-devel@lists.sourceforge.net
-
- -------------------------------------------------------------
-
- Known issues/problems:
-
- * Windows: The floating tool palette does not minimize when
- minimizing a project window. As a workaround, you can
- just keep the tool palette docked with the project window.
-
- * Linux: Full duplex (play one track while recording another)
- does not seem to work, even if your sound card supports it.
- This is likely a problem with the way we are using OSS.
-
- * Linux: Sound cards that only deal with more than two
- channels are not yet supported.
-
- * Mac OS X: Audacity does not process audio while you are
- holding down the mouse button over a scrollbar or menu.
- You must avoid holding down the mouse button too long
- while recording, or Audacity will lose samples.
-
- * Mac OS X: Audacity 1.0 does not support exporting MP3 files.
- This feature will be introduced in a future version of
- Audacity for Mac OS X. (Hint: for now, export as WAV,
- then use iTunes to make MP3's.)
-
- -------------------------------------------------------------

-
- * Playback now mixes tracks, and you can work with the
- document while listening. The stop button works.
-
- * Rewritten file handling functions. The main view
- is no longer dependent on the wxWindows DocView
- classes, so we can handle files ourselves. The
- project file format is now text-based for easy
- debugging. Eventually it will probably move to XML.
-
- * Improved handling of wave tracks: as before, the data
- is stored in blocks, but now, the blocks are correctly
- limited to betweek n and 2n bytes each (for some n),
- which guarantees editing operations always take the
- same amount of time, while also ensuring that projects
- don't get more fragmented over time.
-
- * Rewritten user interface code. The shades of gray
- are taken from the OS, and the project window has been
- redesigned to have more consistent layout across all
- platforms.
-
- * Selecting "Open" now does the smart thing, opening a
- project if you give it a project, or importing a WAV
- file if you give it that.
-
- * Flashing cursor indicates the current editing position
-
- * Much improved ruler - besides looking nicer, the ruler
- now displays the selection and the cursor.
-
- * The zoom tool centers on the cursor so you can zoom
- into wherever you are.
