> VLC on my Mac uses about 130 MB of RAM (as reported by Activity Monitor) to play a FLAC file, and about 300 MB to play a high-bitrate 1080p MP4 file. The audio file memory consumption frankly seems high, but it’s fine, and apparently 1/3 that of WMP.

Not without reason VLC is considered to be a memory hog.
