What people are saying about Raven Pro
Raven Pro 1.5 added a new Selection Review tool to help users review and annotate large numbers of detections in long recordings.
Using the Selection Review tool, the speed in which I am able to analyze
acoustic data has increased immeasurably. I am able to zip through hundreds
of selections in minutes, easily listening to selections of interest and marking
multiple selections at once with the press of a button. I can change the parameters
within the tool to suit different projects for optimal visualization, which makes
my review go even faster. With the assistance of the Selection Review tool, I was
able to analyze 73 days worth of acoustic data in approximately ten working days -
a feat that may have taken months without it! For me, the introduction of this new
tool has solidified Raven as the unquestionable choice in software for acoustic
Using Raven for Teaching the Physics of Music:
We chose Raven for this course because it has the breadth useful for any sound analysis, without the specialization which is typical of many sound programs. This is probably partially true because the Cornell designers, from Canary and through Raven, have worked closely with teachers and students who use Raven for both teaching and research.
Using Raven for Teaching the Physics of Sound:
I've been using Raven for my Physics of Sound class for several years now and the thing I like most about it is it's simple and straight-forward look and ease of use backed-up with real computational power and functionality. Among other things, I use it for teaching about sound waveforms and spectra, filtering, the overtone series, analysis of musical instrument sounds, voice recognition technology, sound spectroscopy, and as a sound player. I really like how I can record and have a real-time waveform and spectrogram presented so my students can see the data unfold as they hear the sound. The interface is very simple to use and most of the GUI area is reserved for data display; this works very well when presented in the classroom. I also use Raven graphical output to make handouts, exam questions, and lecture graphics.
What people are saying about Raven Exhibit
Raven Exhibit was installed at the Whale and Dolphin Conservation Society Wildlife Centre in Spey Bay, Scotland in August, 2009:
The exhibit is a technological feast for eyes and ears, displaying
sounds, pictures and natural history relating to a wide range of whales and
dolphins as well as the environmental and man-made sounds that fill our seas.
Raven Exhibit was made available to visitors at the Bar Harbor Whale Museum on 22 May 2009:
IT'S IN!!! And allow me to express my joy with the exhibit. Several staff have had the opportunity
to mess with it and we find it very enjoyable. Surely it will be one of the more visited exhibits
of the Museum, one I look forward to watching patrons use and admire. I am sure you have both
considered ways to integrate the program into school curriculums, but if you have not gone too
far in that direction I would love to explore it with you both. My brain is racing with ideas.
Sound production and reception is very much like a new dimension and this program allows you to
manipulate that in very fun ways. Students could really step into new perspectives with it...and
new appreciations of the natural world.
Raven Exhibit is being used in the stunning new Wild Center / Natural History Museum of the Adirondacks:
There’s simply nothing else of this quality offered
anywhere else. The installation was effortless. The
sounds of birds and other animals emanating from the
Raven exhibit pull people in—when senses other than
sight are engaged, visitors stay longer and enjoy it more.
From the Cornell Lab of Ornithology, Summative Evaluation of the Interpretive Elements in the Visitor Center (pages 50-58), these are comments on the Sound Studio exhibit, which makes use of Raven Exhibit within a recreated sound archival and analysis studio:
(T)his exhibit afforded and produced more positive visitor experience than any other interpretive device at CLO-VC.
Comparing it to the criteria in Judging Exhibitions (Serrell 2006), the Sound Studio showed evidence of many
aspects of excellence from a visitor-centered perspective.
What people are saying about Raven Lite
From The Singing Life of Birds: The Art and Science of Listening to Birdsong:
Personally, I can’t imagine a world without sonagrams, as I can’t imagine listening without also seeing. I have combined the listening and seeing throughout this book, and I hope that you will continue this practice on your own. Take a CD of bird sounds off your shelf and play it into your computer, now seeing the songs come to life, appreciating the details and the differences among them. Make your own recordings, bringing them home to gorge yourself on the details of how a robin or thrush or warbler sings. Or try the ultimate in techie birding – get the appropriate software program (see below), a laptop computer, and a microphone, and you can watch the songs dance across your computer monitor in the great out-of-doors as you listen to birds there. Listen as you see, and you will hear a different world singing to you.
Using Raven Lite for Teaching the Physics of Sound and Music:
Raven Lite is an excellent tool
for college students who are new to sound
From the classroom and the school yard, where Raven Lite is being used effectively to help teach 9th grade Active Physics in a pilot curriculum project in the Boston Public Schools:
We use Raven Lite in our physics classes, to study the characteristics of bird song. Students get a much richer understanding of wave properties like amplitude and frequency when they can see and hear it in a 3D graph!
The species that I recorded was the Red-winged-Blackbird. I was surprised that there was so many and after I recognized the sound it makes, I was able to identify it every time it sang.
Some feedback on Raven Lite's usefulness in visualizing birdsong:
I just want to say that I love Raven.
I've used it on our Citizen Science weekends, and
Donald Kroodsma's book gave me insight into its potential.
