Acoustic Bat Call Analysis Software

Built upon 25 years of sound science

Why Use SonoBat?

Fine-scale analysis, meticulous and robust data extraction.

Sonobat features parameterization of call data from intelligent trending of high resolution, full-spectrum sonograms, extracting full trends and detecting nuances even in low amplitude or noisy conditions. Such conditions are inaccessible to power trending methods such as zero-crossing.

 

Extensive and broadly representative full-spectrum library. 

Species classifiers based on the most robust, species-confirmed full-spectrum reference library from more than two decades of continent-wide careful tracking, recording, and interpreting bats in the field.

 

Classification engine that integrates vetting experience.

SonoBat species classification integrates quantitative machine learning with algorithms that incorporate more than two decades of expert acoustic classification experience to produce results that surpass machine learning alone.

 

Integrated quality control.

SonoBat knows when to say no. SonoBat automatically recognizes and rejects the many conditions and circumstances that could otherwise result in errant classifications.

Modern, intuitive, easy to use

SonoBat software provides a comprehensive tool for analyzing and comparing high-resolution full-spectrum "sonograms" of bat echolocation calls recorded from full spectrum bat detectors. With its intuitive interface, SonoBat and SonoBatLIVE make it easy to record, process, display, and analyze calls with great sophistication. With SonoBat, you are viewing your bat calls in three dimensions: time, frequency, and amplitude.

Current detector technology enables long-term, uninterrupted recording of full spectrum sound data to enable confident species classification. SonoBat brings automated processing of recorded files and automated species classification- indispensable tools for analyzing long-term and large-scale survey and monitoring projects.

SonoBat is fully compatible with any bat detector hardware producing full spectrum .wav files including those from Avisoft, Batbox, Binary Acoustic Technologies, Elekon, Peersonic, Pettersson, Titley (full spectrum models only), Wildlife Acoustics, and others.

 

Comparing calls is easy

SonoBat lets you append reference calls to a call sequence or an individual call and display them on the same sonogram at identical time and frequency scale to display nuances of call morphology, compare unknown calls to reference calls using the same time scale, and enable on-screen analysis of call data and harmonics. No opening and manipulating other call files in separate windows is required; SonoBat does that for you automatically with point and click simplicity.

One key unlocks them all

SonoBat crafts each regional classifier separately using only the assemblage of species in that region considered against each other. This strengthens the performance of each classifier by optimizing the classification logic for different species assemblages. You should carefully consider what region is most appropriate for your research location. In addition, each SonoBat install contains sub-regions that allow you get more specific with the species in your working area. Those who travel nationwide can install multiple versions of Sonobat; one license key unlocks them all.

Which regional suite of SonoBat is right?

SonoBat makes it easy for occasions when you may need to consider other potential species in a given data set. Refer to the regional suite species matrices to select the most appropriate region that includes your species of interest. Each region may also contain several sub-regions. With a file already displayed on the main SonoBat panel, simply right-click on the classify button to select an alternate sub-region, or use the pull-down selector on a previously batch processed set of files open in the Vetting Table to quickly reprocess the entire batch in seconds.

 

Select a SonoBat Region below to view the sub-regions and included species assemblages. Inquire if you have a need not covered by one of the existing sub-regions. Additional sub-regions are often under development.

Apps for any workflow

SonoBat can help organize your raw acoustic data into one smart workflow necessary for archiving, batch processing, vetting, and ultimately speeding up report creation.·SonoBat·comes with a suite of mini-apps developed over the last two decades which can be used to help solve specific issues when working with legacy workflows and are particularly useful if you own more than one brand of detector and need to bring all your filenames and metadata under one GUANO (a system of standardized nomenclature)-inspired roof.

 

 

SonoBat Data Wizard

Developed to streamline the post-processing data management, the new SonoBat Data Wizard combines the functions of the legacy D500x File Attributer, the Batch Attributer, Dated Batch Attributer, and Batch Scrubber all in one utility, but adds new features as requested by power users worldwide.

 

The Data Wizard takes the .wav files you recorded with any modern detector such as those from Binary Acoustics, Pettersson, Wildlife Acoustics, or even a generic recorder like the H2 Zoom, and saves them with SonoBat metadata attributes, custom notes, and a sophisticated filename nomenclature that you specify or into the world-standard GUANO metadata format. GUANO (https://guano-md.org/) is a new Filename Builder that is a specific standardized file naming system such as what has been refined by Bat Survey Solutions based on 20+ years of experience. The Data Wizard is smart enough to know what brand detector you are using and automatically extracts detector-specific settings and other data embedded natively by the device and reassigns that info into appropriate GUANO fields. The resulting GUANO output is instantly available in the SonoBat Vetting Table and allows you to use Excel to easily organize and filter call files to rapidly find exactly what you are looking for in your project data.

 

The Batch Scrubber is a noise-rejection app for bat detectors lacking strong on-board noise rejection algorithms. The search logic seeks signals with a smooth trend in frequency to retain all but the weakest (and probably unusable) bat signals. To avoid missing bat calls, some non-bat signals with a smooth trend in frequency will pass through without getting scrubbed. The Batch Scrubber can save you valuable time by automatically separating out these files, particularly from monitoring initiatives producing tens of thousands of files to process. With a decade in development and based on noisy survey situations all over North America, the batch scrubber is a robust and dependable app. It's effectiveness is the reason why the modern active monitoring tool SonoBatLIVE reliably records only bat calls.

 

Mistakes happen, and the SonoBat Data Importer can help rectify inaccurate file names with a·built in renaming function.·Specifiy what part of a complex filename to remove or replace and leave the rest. Realize your detector's clock was set wrong? Now you can specify a time offset to fix time zone or other blunders particularly useful for salvaging transect data. Once in awhile it is desirable to remove all metadata from a folder of files. This easily accomplished with SonoBat's metadata nuclear option.

 

SonoBat RefCompiler

Use the SonoBat RefCompiler to build your own reference view compilations. You can extract representative pulses from a positively known call sequence and assemble or splice those selected pulses into a new file. Use this known reference file in the future; it can be displayed alongside unknown calls for comparison in SonoBat.·The SonoBat app comes complete with a huge library of these reference views from across North America, and using this app you can make your own. Note, these are visual reference compilations only; they do not contribute to the species decision engine built into SonoBat.

 

SonoBat Autorecorder

Used only with a detector lacking it's own onboard file storage such as the·Pettersson D240x, this legacy utility automatically downloads files to your computer with a location, date, and time stamp. The AutoRecorder lets you automatically record files and have them saved as SonoBat *.wav files, possessing SonoBat file attributes. You can then analyze them using SonoBat or other signal processing software. This greatly facilitates monitoring efforts, particularly when you would like to simultaneously monitor multiple sites, or tend to other tasks.

 

SonoBat AutoParser

The AutoParser is a specialized legacy utility intended to help you record files from an auto-triggering time expansion detector (e.g. Pettersson D240x) using a suitable digital recorder such as the Samson Zoom H2 as the storage device.·The AutoParser scans through digital recordings to extract sections that have a signal amplitude above a designated threshold and save them as separate time stamped files. Simply set the date and start time of the digitally recorded file, add notes, settings, and a filename start, and then the AutoParser will name the files by appending the date and time of the recordings to a text header. You can then analyze the files using SonoBat or other signal processing software that accepts .wav files.

 

SonoBat license policy

SonoBat licenses software for use on one machine at a time. This permits installation on more than one machine to enable use in different locations, for example a laptop in the field and a desktop for office use. But distinct installations used by distinct users with potential simultaneous operation warrants additional licenses. Please consider our software as you would your hardware in that it requires more than one unit to operate in more than one place at the same time.

True full-spectrum data extraction

SonoBat·takes advantage of high resolution data extraction that considers approximately 80 measurements per pulse to capture subtle call features, far exceeding any other commercial bat call analysis software available. All other North American classifiers rely on data deficient zero-crossing data by comparison.

SonoBat utilizes the complete range of data inherent in a full-spectrum recording to track call signal content using an intelligent tracking algorithm. This provides more robust and accurate data for species classifications.

Does SonoBat's species classification work?
Comparisons have been made between different classifier programs using the available versions at the time. Throughout the years, these comparisons have shown a consistent trend: no classifiers based on zero-crossing recordings have exceeded SonoBat’s full spectrum based classification performance. This suggests that full spectrum data analysis leads to a high percentage of your files that are classified and a high percentage that emerge correct. ·Below is a comparative classification performance of Kaleidoscope and SonoBat on 7115 good quality species-known recordings collected and processed by Janet Tyburec in Missouri (2014). The "% classified" column indicates the percentage of known recordings given a decision, and the "% correct" column indicates the rate of correct classifications of those recordings with a decision.

Summary of four SonoBatLIVE units that collected 1,607 files on the last night of the International Acoustic Symposium in Tucson, AZ in March 2017. Chris Corben spotlighted myotis and identified them all as·Myotis velifer using his experience as a guide and without using auto-ID software. SonoBatLIVE auto classified almost all the myotis as·Myotis velifer. Other results included 753 Tabr accepted and not a single call was misclassified as Laci. The Laxa and Pahe presence was confirmed by manual vetting.

Summary of 1,821 auto-classified files recorded near, but not next to, a colony of bats in September 2014. The actual dataset has been manually reviewed and a majority were identified as Tabr but there were also 3 Laci and 8 Myotis that were correctly Identified by SonoBat. In addition, manual vetting of the 9 Lano files identified by SonoBat revealed them as Tabr files, but SonoBat's probabilistic algorithms calculated an MLE rejecting presence. KaPRO failed to classify 2.5x more files than SonoBat. ·Of the files that were classified, 10% of the Tabr were incorrectly identified as Lano, 20% were incorrectly classified as EPFU, and neither species were actually present in the dataset. When only considering the MLE values, SonoBat more closey reflects the true dataset with one species present, two likely, and one possible. KaPRO reports 6 species present and one possible.

Four recording solutions used simultaneously on an 8-mile continuous transect then displaying only manually verified bat call recordings demonstrates the varability among systems. While all four systems returned essentially the same species set at the end of the night, the SonoBatLIVE/AR125FG combination recorded the largest number of bat recordings files with no extra noise files, making for the most data with least amount of post-processing manual work. The data in the animation below was visualized using Myotisoft Transect.

SonoBatLIVE vs. Echometer Touch 1 • Mt. Lemmon

An Echometer Touch 1 microphone and twin BAT AR125FG microphones were all mounted within inches of each other on a mobile transect during Bat Survey Solutions Acoustic Survey Methods Workshop in April 2017. The screenshot illustrates white markers recorded with one 125FG and Spectr III app with no noise rejection system, then painstaking manually reviewed to remove the extra noise files, leaving only a few actual bat files. This may be then considered the standard to which the other systems compare to. SonoBat's robust noise rejection system allowed mostly bats to pass and relatively few extra noise files, if any. The Echometer Touch accepted an overwhelming number of noise files which also classified (falsely) as bat calls. Ideally all three systems would show roughtly their markers in approximately the same location meaining all systems record the same bat passes at the same times, however this is rarely the case with bat acoustic monitoring.

Help. SonoBat has help-contextual pop-ups available throughout the program. Activate with Ctl -h (or Command-shift-h on a Mac) and then wherever you have your cursor positioned, you will access explanatory messages and tips.

 

Recording Recommendations. Bats make variable, simple single note echolocation calls with only nuanced differences among some species. Confident results depends upon good data, best acquired from microphones placed to have an unobstructed signal path between the bat and the microphone, and by having the microphone elevated above the ground (4 m or more best) and placing the microphone at least a meter from any echo producing surface; 2 m better. This prevents distortion from constructive and deconstructive interference of echoes with the incoming signal. Please follow the suggestions in this linked document before attempting any field recording!
