Public Functions¶

Type	Name
float *	GetTable (size_t idx)
Result	Import (const char * filename)
void	Init (float * mem, size_t mem_size)
Result	SetWaveTableInfo (size_t samps, size_t count)
	WaveTableLoader ()
	~WaveTableLoader ()

Detailed Description¶

Loads a bank of wavetables into memory. Pointers to the start of each waveform will be provided, but the user can do whatever they want with the data once it's imported.

A internal 4kB workspace is used for reading from the file, and conveting to the correct memory location.

enum Result¶

enum daisy::WaveTableLoader::Result {
    OK,
    ERR_TABLE_INFO_OVERFLOW,
    ERR_FILE_READ,
    ERR_GENERIC
};

Public Functions Documentation¶

function GetTable¶

float * daisy::WaveTableLoader::GetTable (
    size_t idx
)

Returns pointer to specific table start or nullptr if invalid idx

function Import¶

Result daisy::WaveTableLoader::Import (
    const  char * filename
)

Opens and loads the file The data will be converted from its original type to float And the wavheader data will be stored internally to the class, but will not be stored in the user-provided buffer.

Currently only 16-bit and 32-bit data is supported. The importer also assumes data is mono so stereo data will be loaded as-is (i.e. interleaved)

function Init¶

void daisy::WaveTableLoader::Init (
    float * mem,
    size_t mem_size
)

Initializes the Loader

function SetWaveTableInfo¶

Result daisy::WaveTableLoader::SetWaveTableInfo (
    size_t samps,
    size_t count
)

Sets the size of the tables to allow access to the specific waveforms

function WaveTableLoader¶

inline daisy::WaveTableLoader::WaveTableLoader ()

function ~WaveTableLoader¶

inline daisy::WaveTableLoader::~WaveTableLoader ()
