Cochlea Modeling Retrospective (2007) - Video of talk by Dick Lyon
Talk given October 1, 2007 for the UC-Berkeley Ear Club.
Richard F. Lyon
Mountain View, CA
"Cochlea Modeling Retrospective"
There is a long history of cochlea modeling that people need to be
aware of, to help design, optimize, and evaluate neuromorphic hearing
systems. In particular, it's important to understand: the notions of
time-frequency and time-scale separation and the classes of filters
that these notions imply; the large-scale AGC and "essential"
nonlinearities that compress the wide dynamic range of sound into a
small representation range; the indirect relationship of transfer
functions to tuning curves; the relative properties of cascade and
parallel filterbanks; the need for higher-order poles to get
realistic transfer functions; why zeros are needed to keep the delay
realistic; and why and how to capture temporal structure for
subsequent processing. We review these topics and some early
contributions to this field.

You need to do FlashVars differently on IE and on the other browsers
FlashVars must be assigned in both the OBJECT and EMBED tags in order to work on all browsers.
Object Tag Example: (Internet Explorer)
<PARAM NAME=FlashVars VALUE="foo=Hello%20Worldgraph=first+line%0Dsecond+line">>
Embed Tag Example: (Other browsers)
<EMBED href="display.swf" FlashVars="foo=Hello%20Worldgraph=first+line%0Dsecond+line" ... (other parameters)></EMBED>

If when you are trying to make a custom MXML component in Flex and you get the error message:
Error: Could not resolve <sness:SimplePlay> to a component implementation.
Make sure you don't have both a SimplePlay.mxml and SimplePlay.as file in your current directory.
My solution is to name the mxml file "SimplePlay.mxml" and the .as file that this file includes named "_SimplePlay.as"
