Coordinate various audio and DSP packages

A few months back I made a naive https://github.com/gummif/Musical.jl unregistered packed for manipulating audio for musical purposes. The samplerate was built into the audio type so I think that is...

Receiving inproc pub/sub messages stops working if proxy restarts

I have had similar issues, where I needed to manually check the connection with pings and disconnect and connect again both the PUB and the SUB sockets (maybe restarting just...

Setting up 2FA for JuliaDSP

It should be active now for me.

Signal Generation

You might want to take a look at the https://github.com/JuliaAudio/SampledSignals.jl package (or see https://github.com/JuliaDSP/Roadmap/issues/10 )

Initial istft implementation.

Here is a working example ``` julia backward_plan{T

Initial istft implementation.

The plan is exactly how it is done in the FFTW module, so FFTW.BACKWARD is apparently not needed.

To avoid allocation (if you have not not so already): ``` julia copy!(tmp1, 1, S, 1+(k-1)*size(S,1), length(tmp1)) ```

Initial istft implementation.

I mean for the `copy!(tmp1, S[:,k])` line. There is also allocation for `tmp2.*win` which could be done with a loop.

Initial istft implementation.

OK good. A small bug: ``` julia 1+(k-1)*winc:((k-1)*winc+n # should be ix + n # with ix = (k-1)*winc ```

Initial istft implementation.

@r9y9 That's a good point. It would however require a bit of pointer hacking like ``` julia tmp1 = pointer_to_array(pointer(S, 1+(k-1)*size(S,1)), size(S,1), false) # replaces copy!(tmp1, 1, S, 1+(k-1)*size(S,1), length(tmp1))...
