... The graph.pl script now makes nodes for header files that do not have corresponding .cpp files. With more nodes, more dependency cycles can be revealed that were not detected before. Two previously known cycles, and two newly revealed cycles, are broken up by easy means (cutting and pasting of code to new files, changes of #include directives) that don't involve more risky transformations. extern declarations were also reviewed. extern declarations should not be in .cpp files (at least for anything Audacity defines) but instead in .h files. Definitions for those declarations should be in the corresponding .cpp files, so that the graph generated by the script really shows all the link dependencies. To obey that rule requires supplying new .cpp files for existing .h files. A similar rule applies for member funtions of classes. So another large, hidden cycle was broken by defining PrefsPanel.cpp.
Audacity is an easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. Developed by a group of volunteers as open source.
- Recording from any real, or virtual audio device that is available to the host system.
- Export / Import a wide range of audio formats, extendible with FFmpeg.
- High quality using 32-bit float audio processing.
- Plug-ins Support for multiple audio plug-in formats, including VST, LV2, AU.
- Macros for chaining commands and batch processing.
- Scripting in Python, Perl, or any language that supports named pipes.
- Nyquist Very powerful built-in scripting language that may also be used to create plug-ins.
- Editing multi-track editing with sample accuracy and arbitrary sample rates.
- Accessibility for VI users.
- Analysis and visualization tools to analyze audio, or other signal data.
