The BirdFox BirdMic One Dual Pack provides a complete solution for capturing crystal-clear audio, ranging from audible bird calls to ultrasonic bat sounds. This set includes a parabolic microphone, an audio interface, and earphones, allowing you to get started immediately using your smartphone. In addition to the 'One' capsule for audible sounds, the kit includes the 'BatMic' capsule, designed for listening to and recording ultrasonic frequencies. You can easily switch between the two capsules while out in the field.
Thanks to its compact design, the system fits effortlessly into a backpack. No additional equipment is required, making it an ideal choice for both beginners and experienced users. You can listen in real-time, create high-quality recordings, and visualize the sounds using dedicated apps—a feature that helps with the immediate identification of bird species. The app for bats determines the call frequency and suggests a genus, though it does not include automated species-level identification software for bats.
The parabolic dish primarily amplifies frequencies from 1.5 kHz upwards, making it ideal for high-pitched sounds, such as birdsong. Its analog design ensures a virtually noise-free recording. The "One" capsule captures a broad frequency range—from 20 Hz to 20 kHz—while the "BatMic" capsule covers the 20 kHz to 80 kHz range, allowing for the detection of ultrasonic sounds. These ultrasonic frequencies are converted into sounds audible to the human ear—manifesting as a series of clicks—by dividing the frequencies by a factor of 10.
Convenient controls allow you to optimize the sound before recording:
- Reduce distracting low-frequency noise, such as wind or traffic.
- Amplify faint sounds using the boost function.
You can listen in real-time via earphones, enabling you to monitor audio quality instantly. The system operates independently of your smartphone’s built-in microphone, ensuring consistent results every time.
Differences between the BirdMic One Pack, BirdMic Pro Pack, and BirdMic Pro Dual Pack
The BirdMic One Pack is a straightforward, all-in-one solution for beginners who wish to record and listen to audible sounds (such as birdsong) in real-time using their smartphone. It is a compact, user-friendly system, perfect for recreational nature observation. The BirdMic Pro Pack is an advanced kit designed for users who demand superior sound quality, greater control, and broader versatility—including compatibility with cameras, external recorders, and professional field-recording setups. Both the BirdMic One Pack and the BirdMic Pro Pack focus on the audible frequency range (20 Hz – 20 kHz) rather than ultrasonic sounds. However, these kits can be expanded with an optional BatMic capsule, which brings ultrasonic sounds within reach. The BatMic capsule for ultrasonic sound is included as standard in both the BirdMic One Dual Pack and the BirdMic Pro Dual Pack.
