Member Function Documentation

static void dpp::audio_mixer::collect_single_register	(	int32_t *	data_in,
		int16_t *	data_out,
		float	current_gain,
		float	increment
	)

inlinestatic

Collect a single register worth of data from data_in, apply gain and increment, and store the result in data_out. This version uses x64 instructions.

Parameters

data_in	Pointer to the input array of int32_t values.
data_out	Pointer to the output array of int16_t values.
current_gain	The gain to be applied to the elements.
increment	The increment value to be added to each element.

static void dpp::audio_mixer::combine_samples	(	int32_t *	up_sampled_vector,
		const int16_t *	decoded_data
	)

inlinestatic

Combine a register worth of elements from decoded_data and store the result in up_sampled_vector. This version uses instructions.

Parameters

up_sampled_vector	Pointer to the array of int32_t values.
decoded_data	Pointer to the array of int16_t values.

constexpr int32_t dpp::audio_mixer::byte_blocks_per_register { 2 }
