Earth Notes: Yearly Electricity Grid Flows SonifiedUpdated 2023-07-15.
[Yearly total 16WW grid electricity flows (imports plus exports), house percussion and bass, converted to audio via GarageBand and Audacity.]
MIDI generated via V5.2.5 of the V5 Java
statsHouse implementation on GitHub, run through GarageBand as-is and bounced to SoundCloud in lossless format (AIFF), and converted in Audacity to FLAC and MP3.
File sizes note
Starting with ~400 bytes of CSV source data containing 15 data points, the full 'house' MIDI file is ~10kB, but compresses back down to ~0.5kB with
zopfli in this case. On-the-fly compression by a Web server will likely be close. (The
brotli-compressed version is smaller than the source CSV.)
The AIFF uncompressed lossless file at the other extreme, as sitting in SoundCloud, is ~35MB, thus ~65,000 times larger! The FLAC is ~14MB, the best MP3 ~3MB and a mono lo-fi MP3 ~900kB.
For most uses, with a decent synthesiser, there will be little effective difference between the compressed MIDI and the 'good' MP3 at a ratio of ~6,000x or nearly four orders of magnitude!
