Frog calls were recorded and compiled by Ulmar Grafe and Maximilian Dehling. This website is a companion to : Inger, R.F., R.B. Stuebing, T.U. Grafe & J.M. Dehling 2017. A Field Guide to the Frogs of Borneo. 3rd Edition. Natural History Publications (Borneo). Kota Kinabalu. Frog photos displayed on this website were taken by Maximilian Dehling and Ulmar Grafe

Most frog calls were recorded in Brunei or in the Malaysian states of Sabah or Sarawak. The species have been sorted into three categories to allow easier identification depending on where a listener is: (1) urban, heavily degraded habitat, (2) forests at low elevations (<900 m ASL), (3) forests at high elevations (> 900 m ASL).  Advertisement calls of 67 species are made available as well as four soundscape recordings in which the full complexity of frog chorusing behaviour can be heard. UTNP = Ulu Temburong National Park, Brunei, BBBR = Bukit Baka Bukit Raya, West Kalimantan.
