Bat Synth is a tool for bat educators and trainers. By attaching a 384kHz USB-C DAC and ultrasonic amplifier / speaker (such as Bat Signal : https://www.pcbway.com/project/shareproject/Bat_Synth_2_b06cbf4c.html) to your phone you can create authentic-sounding bat echolocation calls, inaudible to humans, but which can then be revealed using a bat detector, or the Bat Detector iPhone app. In addition to bat calls a test tone generator is included, which can be used as part of bat education by illustrating how certain sounds can only be heard by young people, and other sounds cannot be heard by anyone at all as they are too high-pitched, and can only be revealed by a bat detector. Included bat calls are : Simulated bat passes : Common Pipistrelle featuring echolocation calls, social calls and feeding buzz Soprano Pipistrelle featuring echolocation calls, social calls and feeding buzz Echolocation calls only : Noctule Serotine Barbastelle Brown Long-Eared Bat Bechstein's Bat Daubenton's Bat Greater Horseshoe Bat Lesser Horseshoe Bat The app operates by synthesizing a 5 second fragment of the bat call which is then looped. These fragments are stored as .wav files within the app in Files->On my Phone->Bat Synth so can be retrieved and analysed.
