Constructor & Destructor Documentation

template<class T >

pico_arduino::SoundBuffer< T >::SoundBuffer	(	int	buffer_count,
		int	buffer_length,
		double	amplifier = `1.0`,
		T	clip = `0`
	)

inline

Construct a new Sound Buffer object.

Parameters

buffer_count	number of buffers
buffer_length	number of entries in one buffer
amplifier	factor by which each sample is multiplied
clip	amplified values above this value are clipped (clipping is deactive if value is <=0)
