Hi Kevin,

> and when i look at the data it seems to missing the time. 

There's no time missing. Samples don't have the property "time". They
are just numbers. (This is a very common thing for DSP beginners to be
confused about. Just imagine you're a computer presented with a
sequence of numbers. It's just numbers. If you want to attach the
meaning "sample at time t", that's a human thing to do; none of the
algorithms applied to the sample are aware of that.)

If you know that these samples are still time domain, and you know the
sample rate, then there's really nothing you need: The n'th sample
simple belongs to the point in time "time of the first sample +
n/sample rate"; done.

Best regards,
Marcus
