No more discrete frequencies for non periodic signals.
Continuous spectrum.

OTAH, a sine wave with an *envelope* applied isn't a  discrete
frequency either. 

(Academical) Question: 
Imagine a sound that was created *only* by a number of periodic 
waveforms, a linear (no overdrive) VCF with envelope, and a linear 
VCA with envelope. Is it possible to resynthesize such a sound 
with a *finite* number of *fixed* frequency oscillators and individual
VCAs / envelopes ?
I know this is far from real life sounds, but I just wonder if this can work
 or not.
