Struct SamplePlayer 

pub struct SamplePlayer<T: Transcendental> { /* private fields */ }

Sample-playback algorithm built on InterpolatedReader.

Plays back a fixed buffer with variable rate, interpolation, and configurable looping. Implements Algorithm for use in signal graphs, and Generator for compatibility with the oscillator trait hierarchy.

Generator parameter mapping

Generator	Meaning for SamplePlayer
frequency	Pitch: rate = freq * len / sample_rate
phase	Normalised position (0 = start, 1 = end of buffer)
amplitude	Output gain
