% shepardtones.m - plays the shepard tones
% based on an example I found here: http://hebb.mit.edu/courses/9.29/2003/athena/auditory/matlab/shepardtones.m
% adjustable parameters
max_time = 2; % time for each tone
max_repeat = 3; % number of loops
A = 440; % "base frequency"
num_harm = 7; % number of harmonics used for each tone
sigmasq = 1; % variance of the amplitude for each partial

Julia answer to text benchmarks (http://matthewrocklin.com/blog/work/2014/01/13/Text-Benchmarks/)
function groupby{T}(fn::Function, seq::Array{T})
dict = Dict{Any, Array{T}}();
for item in seq
key = fn(item);
if !haskey(dict, key)
dict[key] = [];
end
push!(dict[key], item);
end
return dict;

Passing structures and arrays back and forth in Julia with ccall
immutable Cdvec
val::Ptr{Cdouble}
len::Clong
end
a = [1.0, 2.0, 3.0]
b = [3.1, 4.2, 7.3]
Ca = Cdvec(pointer(a), length(a))
Cb = Cdvec(pointer(b), length(b))
