WAC (file extension:
.wac) stands for Wildlife Acoustics Compressed Format.
This is a legacy proprietary audio file format used by Wildlife Acoustics.
Besides acoustic data,
WAC files may also contain GPS information, if the
recorder was GPS-enabled.
WAC files are supported by the Kaleidoscope Pro
Analysis Software. Otherwise, the bioacoustics package in R is able to read and
WAC files to the
WAVE format. See the Converting audio files withR
section for more information.
