If you are purchasing bcAdmin together with a Batcorder 3, please select the "Batcorder 3 with bcAdmin 3.0" option from the Batcorder 3 page in order to get the software for the reduced price of £817.
bcAdmin is the main application for managing and analysing Batcorder recordings. It stores information on recordings, sessions and locations in a database for further evaluation. It is designed to complement the Batcorder but works with other recordings as well. bcAdmin implements the analysis of bat call sequences and stores measurements in special files for identification with batIdent (the free software that provides a reference library of over 70,000 bat calls and counting). Bat activity can easily be displayed in tables or graphs generated by bcAdmin. The latest version of bcAdmin provides better performance, improved user interface and greater functionality. It can now run analysis in the background while you are working in the foreground, making batch processing even easier, and you can now open multiple call databases at the same time, making it easy to compare calls or copy and paste between databases. There is no longer a need for additional plugins, so functionality such as the Geo-plugin (for geo-tagging your recordings) is now included in the one package. You can flag, search and sort your recordings, so it has never been easier to store and manage even large datasets.
bcAdmin is the first application that offers the management and storage of calls and their meta information according to sample date and location (sessions). Information like location and recording times are collected and stored in connection to each recording. In interaction with batIdent, recordings are identified at genus and/or species level. After importing these results, reports or graphs can be created displaying the available data. You can now display bat activity across or within nights using just one click. bcAdmin is designed to import the recording information per session. Recordings can be analysed in batch mode resulting in measurements of each call of a sequence. These are stored in a file per call sequence (csv and bcCalls) and species can be extracted with batIdent automatically. Different options for summarization and filtering of data exist and help create meaningful reports. RAW files are generated but these can be exported to WAV format. There is now improved handling for non-Batcorder audio files, so stereo calls can be analysed and the analysis of calls from other bat detectors is improved.
While bcAdmin in general can deal with many different recording devices, there are some prerequisites that improve the automatic measurements. We recommend you use real time recordings of at least 350kHz sample rate (500kHz preferred). Amplitude resolution must be 16 bit. System noise should stay below -45dB (relative to maximum resolution). The Batcorder records with a system noise of -53dB or less. The SNR (signal to noise ratio) has a strong influence on the process of automatic measuring of calls. The worse the SNR, the less reliable the identification process will work.
The Batcorder system has been designed to be highly automated, virtually eliminating analysis time for users. This makes it ideal for long term monitoring projects, large studies and busy consultants! Please note that if you would also like the option of manual call analysis, you will also need bcAnalyze.
bcAdmin, along with all the Batcorder software, is only available for Macs, with no Windows version planned due to the high costs associated with such development. We recommend buying a mini-Mac (available from many computer retailers - shop around for a good deal!), but any Mac will do providing it is a Mac O S X 10.7 or newer. Whilst this is an extra up-front expenditure, the time savings from using the automated analysis software will recoup any initial outlays very quickly. Please note, the Batcorder software is not compatible with iPads.
