The widest vocal range of any human is 10 octaves ranging from G/G#-5 to G/G#5 (0.7973 Hz - 807.3 Hz), achieved by Tim Storms (USA) at Citywalk Studios in Branson, Missouri, USA, on 1 August 2008.

Mr. Storms also holds the record for the lowest vocal note.

The notes achieved are actually between G and G#, so in terms of concert tuning his range is actually 9 octaves and 11 semitones, however because we use a hertz measurement the range is recognised as the full 10 octaves.
