DESCRIPTION="Free crossplatform audio editor"
HOMEPAGE="https://www.audacityteam.org/"

# A header-only thread pool library, without a build system, about 100
# lines of code.  Probably not worth packaging individually.  Check
# cmake-proxies/CMakeLists.txt and search for "ThreadPool".

# dev-db/sqlite:3 hard dependency.
# dev-libs/glib:2, x11-libs/gtk+:3 hard dependency, from
#   cmake-proxies/cmake-modules/dependencies/wxwidgets.cmake
# sys-apps/util-linux hard dependency, from cmake-proxies/CMakeLists.txt
#   for libuuid
# portmidi became non-optional: building without it results in build
#   failures, even with some of the Debian patches.  It's probably not
#   in our best interest to fix that as a patch series.
# glib, gtk and gdk are all directly relied on in the source, not just

# Libraries used at runtime via dlopen:
# - dev-libs/{serd,sord} - for LV2 support
# - media-libs/{opus,sratom} :: For Opus and LV2 respectively
# - media-sound/lame :: For MP3 export
# - media-video/ffmpeg :: For generic FFMPEG export
#   This one has the interesting property of many versions being
#   supported at runtime.  See: libraries/lib-ffmpeg-support/impl
#   Current support grid:
#   - Lavf - 5[789]
#   - Lavc - 5[789]
#   - Lavu - 5[2567]
