yes it has to be played out at higher sample rates, so I start at the
original sample rate and end at sample rate * some chosen value
how long will it take to play the whole
Can you explain your notation a little bit? Is x[t] the sample index into
your signal? And t is time in samples?
I might formulate it as a Delta of indicies where a Delta of 1 is a normal
playback speed and you have some exponential rate. Would something like
this work?
delta *= rate
t += delta

Hello all,
The first public release of the Gaborator library is now available.
The Gaborator is a C++ library that generates constant-Q spectrograms
for visualization and analysis of audio signals. It also supports an
accurate inverse transformation of the spectrogram coefficients back
into
Let's let t be the time, and s be the position in the buffer. So, for
example, playing back at double speed you'd just have s=2*t.
To make it exponential, and have s=0 at t=0, we can write:
s = C*R*(e^(t/C) - 1)
Here R is the initial playback rate (R=1 if it should start at normal
pitch), and C
I am having trouble with this concept for quite some time now, I hope that
I can explain it well enough so you can understand what I mean.
I have signal stored in a buffer of known length. The buffer must be read
at a variable speed, and the variations in speed have to be exponential, so
that the

If you can derive an average rate out of it then you can determine it.

I'm hoping to make some formant synthesis patches with my modular soft
synth Moselle. http://moselle-synth.com
I've looked around for formant tables and find tables with more vowels and
fewer formants, or fewer vowels and more formants. Tables with amplitude
seem to have fewer vowels and only
I take it you're using this formant table:
