Introducing Mormyroscope EOD recording software
Mormyroscope is the first publicly available software application specifically designed for making digital recordings of electric fishes. The application is a customized version of Soundcard Scope software written and published by Christian Zeitnitz, Professor of Physics at Wuppertal University, Germany. It is free for non-commercial educational and scientific use. This program will run on Windows 2000/XP/Vista/7/8/10 (32 bit and 64 bit) computers and tablets. It will not install on older versions of Windows.

Mormyroscope offers all the features of Soundcard Scope while adding specimen- and recording-specific file names and metadata to the output files. It has an interface in both English and French and a cool logo you see above by JaeCreative.
Mormyroscope is intended to be used with an external USB audio interface (="sound card") using an electrode plugged into the mic input of the device.
Waveforms are visualized in an oscilloscope window that offers all the controls of a standard oscilloscope. Waveform snapshots (one millisecond to several milliseconds in duration) are saved simultaneously as jpeg image files and .csv data files from which data can be plotted and superimposed in a spreadsheet or graphing application. Before saving files, the user is prompted to enter metadata associated with the specimen, the recording, the project name & the recordist. These data are written to a header in the .csv file and also written to a separate .txt file. Recordings of long trains of EOD pulses of several seconds to several minutes can be saved as .wav files in the Recorder window of Mormyroscope. Metadata are also embedded in the header of the wav file.
A poster presented at the 2018 PAFFA conference in Malawi in which we describe this setup is available here. Also see How to record EODs and other related articles here on this blog.
The English language manual for the regular version of Soundcard Scope is available here.
An updated version with bug fixes was uploaded on 19 September 2019.
Pointer: before running Mormyroscope on your Windows PC, be sure to install the appropriate driver recommended by the manufacturer of your audio interface. Then make sure that your computer recognizes the device and it is selected for audio input in Settings --> System --> Sound app, or in the Sound Control Panel. Also make sure the interface is acquiring data at its fastest rate, e.g. 192 kHz if it's capable.
Please let us know if you find Mormyroscope useful and if you have suggestions to improve it!
Development of Mormyroscope was made possible by the MbiSa Congo I (2013-2018) project, a framework agreement project of the Royal Museum for Central Africa, Tervuren, Belgium, with funding from the Belgian Development Cooperation.
