These files are shortened (leading silence removed, a fade added), set to a consistent loudness, and encoded to MP3. Each note's pitch was measured and checked; a few mislabelled or noisy recordings were left out, and the glockenspiel is filed an octave above its file names, where it sounds. CC0 needs no credit; it is given anyway.
