Hello Waveforms is the ninth album by British electronic musician and record producer, William Orbit.

It is a mostly instrumental ambient record, with only four tracks containing vocals: "Spiral", featuring Kenna and the Sugababes, "They Live In The Sky", sung by Annette and Paulette Morris, and "Bubble Universe", which is based on a song previously recorded with Madonna called "Liquid Love", and has vocals by Laurie Mayer.

All tracks are written by Orbit, either alone or in collaboration with Laurie Mayer and Rico Conning.

G155 is a track from the "Hello Waveforms" recording sessions that was not included on the album.

It can be heard on William Orbit's official website[12] and was issued as a promo single on 7" vinyl only.
