Detailed Description

template<typename T = float>
class pulp::signal::SmoothedValue< T >

Linear smoothing for control-rate parameters.

Real-time safe; no allocations. Use for parameter smoothing where the linear ramp is perceptually correct (gain in linear units, mix, pan position, etc.).

For parameters where the linear ramp is perceptually wrong — pitch, frequency, gain in dB — use LogRampedValue (in core/signal/include/pulp/signal/log_ramped_value.hpp) which applies a multiplicative (geometric) per-sample step so equal time produces equal perceptual change across the range.

The two utilities together cover Pulp's smoothing surface; consumers pick the curve that matches the parameter's semantics.

RT contract: this helper stores only scalar state and allocates no memory.

set_ramp_time(), set_target(), set_immediate(), next(), skip(), and accessors are audio-thread safe when externally synchronized like any other mutable control object.

template<typename T = float>
