Sounds and Sonograms (Spectrograms) of bird songs and calls

Egyptian Grasshopper © Fraser Simpson I'm currently building a small sound library of grasshopper and cricket stridulations. MP3 versions of the original wave recordings made in the field can be sampled here. These sound recordings have been made using various pieces of gear from a minidisc recorder coupled with an inexpensive microphone to professional Sennheiser and Roland equipment. Field recordings have been cut and prepared for the web with MAGIX Audio Cleaning Lab or Audacity. Field notes and recording data, including GPS readings, are compiled in a database.

Accompanying most sound recordings is a corresponding sonogram for all or part of the sample. A sonogram is a visual representation of sound in a graphical form with frequency (analogous to pitch) in Hertz (wave cycles of sound per second) on the y-axis, and time (in seconds) on the x-axis. These sonograms have been produced using Syrinx software (www.syrinxpc.com) which allows real-time spectrographic recording, analysis and playback. I then label or annotate the sonogram bitmap images in Adobe Photoshop.

The sonogram pages require Flash to work. You may need to change your settings to allow Flash. To the left of the web address, click Info Information. At the bottom, click Site Settings. In the new tab, to the right of 'Flash', click Allow. Go back to the site and reload the page.
