Controls the playback speed of this particular sample, as a multiplier
of its original speed. Setting it to 0.0 is liable to crash.
If unimplemented, the getter will always return 1.0. This is nearly always the
case if you compile with -version=without_resampler.
Please note that all members, position, duration, and any
others that relate to time will always return original times;
that is, as if playbackSpeed == 1.0.
Note that this is going to change the pitch of the sample; it
isn't a tempo change.
