Detailed Description

The physical tier for one channel.

Member Function Documentation

chew_state_index()

std::size_t pulp::signal::chardelay::TapePhysicalChannel::chew_state_index ( ) const

inlinenoexcept

gap_coefficients()

const std::vector< double > & pulp::signal::chardelay::TapePhysicalChannel::gap_coefficients ( ) const

inlinenoexcept

in_loop_delay_samples()

double pulp::signal::chardelay::TapePhysicalChannel::in_loop_delay_samples ( ) const

inlinenoexcept

Total in-loop delay this tier contributes ahead of the delay line's read: the oversampler's group delay plus both halves of the loss cascade.

The engine subtracts this from the requested line delay so the echo still lands on the requested time and latency_samples() can stay 0.

loss_parameters()

TapeLossIirParams pulp::signal::chardelay::TapePhysicalChannel::loss_parameters ( ) const

inlinenoexcept

oversampler_latency_samples()

int pulp::signal::chardelay::TapePhysicalChannel::oversampler_latency_samples ( )

inlinestaticnoexcept

Group delay the oversampling wrap adds inside the loop, in host samples.

post_process()

double pulp::signal::chardelay::TapePhysicalChannel::post_process ( double x )

inlinenoexcept

Wallace loss → head bump → hiss → chew → degrade → DC block.

pre_process()

double pulp::signal::chardelay::TapePhysicalChannel::pre_process ( double x )

inlinenoexcept

Record EQ → oversampled hysteresis → makeup → playback EQ.

prepare()

void pulp::signal::chardelay::TapePhysicalChannel::prepare ( double fs )

inline

recover_audio_fault()

void pulp::signal::chardelay::TapePhysicalChannel::recover_audio_fault ( )

inlinenoexcept

Fresh-state recovery without clearing dynamically sized FIR storage.

reset()

void pulp::signal::chardelay::TapePhysicalChannel::reset ( )

inlinenoexcept

set_seeds()

void pulp::signal::chardelay::TapePhysicalChannel::set_seeds ( std::uint32_t base )

inlinenoexcept

set_speed_ips()

void pulp::signal::chardelay::TapePhysicalChannel::set_speed_ips ( double ips )

inline

Control-thread only: redesigns both filters and starts the crossfade.

The outgoing design keeps running in its OWN complete filter instance and the two outputs are crossfaded — never a blend of coefficients, which for the recursive half would apply mixed coefficients to state belonging to neither design. The incoming stage inherits the outgoing one's FIR history (delayed input samples, meaningful under any coefficients) and starts its recursive half from zero, which the crossfade covers because the incoming stage's weight is still near zero while it warms.

speed_ips()

double pulp::signal::chardelay::TapePhysicalChannel::speed_ips ( ) const

inlinenoexcept

update()

void pulp::signal::chardelay::TapePhysicalChannel::update ( double age )

inlinenoexcept

Control-rate update. In this tier character_amount IS the age axis.
