Save call records as wave files, analyze and display using the SELENA software, and determine which calls are produced by males or females.
! CAUTION It is difficult to record rare vocalizations from female frogs.

Use an ultrasonic microphone and PC Tape system and/or a digital audio recorder with a microphone for picking up calls. tormota at night, kept individually in an open-top plastic container with a gauze cover. an infrared videorecorder (e.g., Sony DCR-TRV30E, or other models).a calibrator (Bruel & Kjaer 4231) that produces a 1 kHz tone at 94 dB SPL.a condenser microphone (Bruel & Kjaer 4135) and a precision measuring amplifier (Bruel & Kjaer 2610) to measure sound pressure level.a digital audio recorder (e.g., Sound Devices, model 702, USA) with a 1/4” wide-band condenser microphone (G.R.A.S.an MP3 player with a power amplifier and a broadband speaker (Fostex FE87E, Japan) to broadcast acoustic stimuli.The WAV files of recorded calls are stored on the flash memory of the Unit for broadcasting through an audible loudspeaker (Visaton DSM25FFL pass band 2–22 kHz or Fostex FE87E pass band 0.1–40 kHz), or an ultrasonic loudspeaker (Polaroid pass band 22–120 kHz) or both, at various playback levels

This protocol is used to demonstrate that the ultrasonic concave-eared torrent frogs Odorrana tormota inhabiting noise habitats, as a model of acoustic communicating animals, show hyperacute phonotaxis to the female’s courtship calls (1). The protocol describes quantitative analysis of males’ phonotaxis induced by female calls.
