The use of envelope detection methods to reduce the bandwidth of an echolocation click into the
audio-band is not a new concept. However, the increasing popularity of portable digital recorders
with excellent signal to noise performance needs such signal processing if ultrasonic transient
data needs to be captured. Similarly, this approach allows high frequency information to be
recorded onto video recorder sound tracks providing the advantage of synchronised sound with
images for behavioural studies. This paper describes the development of a new generation of
ECD with improved performance and includes cetacean echolocation data recorded using this
equipment in two independent studies.
