◆ free_wave_settings()

void free_wave_settings ( wave_settings_t * wave_ss )

Free the wave_settings structure.

Parameters

[in,out] wave_ss The pointer to the wave_settings

Generate a waveform inside of a buffer based on a frequency, rate, wave type and duty_cycle.

Parameters

[in,out]	buf	A pointer to the sound buffer
[in]	size	The size of the buffer
[in]	wave_ss	The sound settings of the wave

wave_settings_t * generate_wave_settings	(	float	frequency,
		float	sample_rate,
		unsigned int	volume,
		duty_cycle_t	duty_cycle,
		wave_t	wave_type )

Allocate a wave settings structure and return its pointers.

Parameters

[in]	frequency	The frequency of the wave
[in]	sample_rate	The sample rate of the wave
[in]	volume	The volume of the sound wave (also called amplitude)
[in]	duty_cycle	The duty_cycle of the wave (only used for Rectangle waveforms)
[in]	wave_type	The type of the wave

Play a sound based on a sound buffer, a sound interface and a the buffer size.

Parameters

[in]	buf	A pointer to the sound buffer
[in]	s	A pointer to the sound interface
[in]	size	The size of the sound buffer
