There are a wide range of bat detectors on the market which vary in price from less than a hundred pounds to more than several thousand. Buying direct ends to be cheaper than buying through other suppliers.
What about digital recorders?
If you want information about digital recorders try BCT Guide to digital recorders.
Again we have a range of devices we use, (most of which are cheap and cheerful). New models seem to come onto the market every few weeks. Despite what some say these give more than adequate recordings for sonogram analysis
More expensive pieces of kit give better quality clearer recordings,
e.g. zoom recorders
You can buy commercial software such as Adobe audition but these are very expensive. and contains many features you will never use if all you want to do is analyse bat calls.http://www.adobe.com/products/audition/features.html
Newly released is an open source piece of software called Audacity which is very well worth a look and above all is free. We’ve downloaded it recently and have fallen in love with it. http://www.download-audacity.com/
