Every real sound is physically distorted at its onset by inertia.

Evidence

For man, the perfectly pure and mathematically defined sound exists as a theoretical concept only. The French mathematician Fourier knew and stated this when he was developing his theory of harmonic analysis. Distortion results the moment a sound is produced, for the sounding object first has to overcome its own inertia to be set in motion, and in doing this little imperfections creep into the transmitted sound. — Schafer, Murray R, The Soundscape- Our Sonic Environment…, 880
