Lookup is the lookup table used to draw a 2×3 dot rectangle with symbols.

The order of bits in the rectangle of dots by which it is indexed is:

0 1
2 3
4 5

It must contain at least 64 elements.

Functions

func Dump

func Dump(prr error, b []float64) error

Dump prints the waveform of the audio to Stderr.

func DumpWriter

func DumpWriter(prr error, out io.Writer, b []float64) error

DumpWrited prints the waveform of the audio to out.
