Swift – Frequently Asked Questions
August 14, 2017
Q1: Will the Swift configuration tool work on a Mac?
A1: The configuration tool currently only works on a Windows platform. Other users have reported successfully using Parallels to configure the Swift units. BRP has not tested this method and cannot guarantee that it will work. BRP uses the NuVision Solo 10 Draw TM101W610LBL Tablet to program our units in the field.
Q2: Is there software available to assist with analysis of the Swift data?
A2: Yes, we have Raven Lite and Raven Pro. Raven Lite is our free (general public) program that allows users record, save, and visualize sounds as spectrograms and waveforms. It is intended for students, educators, and hobbyists. Raven Pro is our workhorse analysis software package. It is a powerful, user-friendly research and teaching tool for scientists working with acoustic signals.
Q3: Will a AA to D-cell battery adapter work with the Swift unit?
A3: There is no technical reason to believe that the AA to D converter would not work, but BRP has not tested this configuration, so we cannot guarantee that it will work.
Q4: Do you offer any discount pricing on the Swift units?
A4: We cannot provide any discounts because the price we charge is our costs. Our goal is to provide the best unit we can at an affordable price to the research community.
Q5: Do you have a rugged housing that can withstand harsh environmental conditions?
A5: Yes, we have a version that we fit into a customized Pelican case that is sturdier and works better in areas where animals may “inspect” the units. This version has a slightly higher price – please email us for more information.
Q6: Can you please provide some more information on the accessories I will need in addition to the recorders and where I can purchase them?
A6: You will need to purchase 3 D-cell batteries for each unit and a SD card. We recommend Panasonic Industrial batteries and the SanDisk Extreme Pro SD card. This is a link to a 128GB SD card – any size card of this type will work.
Q7: How much data will the Swift recorder produce and how long will it run?
A7: The table below shows approximate runtimes. These times may vary depending upon temperature and type of batteries. These estimates were made assuming new alkaline batteries:
|Sample Rate (Hz)||Approx Runtime (Hrs)||Approx Runtime (Days)||Data Generated per Day (GB)||Data Generated over Runtime (GB)|
Q8: What is the frequency range of the Swift units?
A8: The units can be programmed to record at 8kHz, 16kHz, 32kHz, 48kHz or 96kHz sample rate. The sample rate is two times the effective recording rate. For example, setting the sample rate to 16kHz, will record with an effective record rate of 8kHz.
Q9: What kind of microphone is on the Swift unit?
A9: The manufacturer of the microphone is PUI Audio. Part number is POW-1644L-B-LW100-R. It is omni-directional and has a signal to noise ratio (min) of >58db with a frequency response of 50 Hz to 16kHz. If you require additional information about the microphone, please email us.
Q10: I lost the USB cable you sent me. Can I use the cable that I use to charge my smartphone?
A10: The cable is a standard USB 2.0 micro USB cable that is commonly used to charge cell phones and other devices.
Q11: Does the Swift record in dual-channel mode?
A11: Currently, the Swift recorders do not function in dual-channel recording mode. The circuit board and microphone connector are capable of dual-channel recording. However, the microphone and the firmware are not. This is something that we plan to develop on a future version.
Q12: What is the file format produced by the Swift unit?
A12: The Swift produces WAV files. The file size is configurable using the Configuration Tool.
Q13: What is the bit depth of the Swift?
A13: The Swift records with a 16-bit word length.
