Add `locale/en.po` file. Add English to `locale/LINGUAS` list. Partially duplicate `msgid`s to `msgstr`s in English locale enable eventual key `msgid` changes Replace former project name with Tenacity in English locale. Replace former project website with Tenacity compatible usages in English locale. Modify `AboutDialog.h` by renaming variables. Modify `AboutDialog.cpp` by replacing usage of pre-fork name in Strings. Modify AddBuildInfoRow methods to be static in About dialog. Make License text const in About dialog. Make pre-fork credits different in About dialog. Begin adding Tenacity specific credits Macros starting with `__` are reserved, so I removed the `__` on the About Dialog guard macro. Remove `AboutDialog::` from usage of `Role` in `AboutDialog.h` Refactor overly long generator method into separate methods in `AboutDialog.(h|cpp)` Begin adding Tenacity developer information Cleanup layout of `AboutDialog.h` and `AboutDialog.cpp` Add `safedelete` macro to compliment odd `safenew` macro Add `enum` to `ShuttleGui.cpp` to make it more clear what `Prop` method is doing. Remove a ton of pointless and/or redunant `#ifdef` usage Remove pointless singleton in AboutDialog Make AboutDialog modal on MacOS Fix reference type use of `auto` in `AudacityApp` b/c it makes unintentional copy. Update XPM and PNG images using Tenacity assets Update ICO images using Tenacity assets. Fix Windows resource script that improperly used `winuser.h` import. Add `*.aps` to gitignore to prevent IDE RC pre-load file from being committed. Add default values for pre-processor constants in `tenacity.rc`. Make changes needed for `Tenacity.exe` binary Add 8x8 PNG to Windows ICO files Replace project name in various CMake and CPack file. Replace project name in various directory structures. Replace project name in various OS-specific build files. Replace project name in various documentation files. Update the PO and POT files using the script. Fix places where a `.desktop` file was used on Linux. Replace title of project windows. Make splash screen click through to `tenacityaudio.org`. Remove ® from `AboutDialog.cpp` Modify copyright message in `AboutDialog.cpp` Signed-off-by: Emily Mabrey <emilymabrey93@gmail.com>

\class Resample
|
|
\brief Interface to libsoxr.
|
|
|
|
This class abstracts the interface to different resampling libraries:
|
|
|
|
libsoxr, written by Rob Sykes. LGPL.
|
|
|
|
Since Audacity always does resampling on mono streams that are
|
|
contiguous in memory, this class doesn't support multiple channels
|
|
or some of the other optional features of some of these resamplers.
