# This script edits the Ardour source code to change all references to "audio frames" into "audio samples". We skip 3rd party and special libraries,
|
||||
# and after the global edit do a bunch of per-file fixups for things that the global edit can't take care of.
|
||||
#
|
||||
# This was written so that it can be run after merging various PRs and development branches in the near term (July 2017) future.
|
||||
#
|
||||
# It also reveals just how confusing this naming "scheme" was.
