Functions

clamp(int x, int y) → int

Returns the closest number to x int the range 0, y.

fold(int x, int bits) → int

Shifts int x of bit width bits up by half the total range, then wraps any overflowing values around to maintain the bit width. This is used to convert between signed and unsigned PCM.

intToSample(int x, int bits) → double

Converts an int x of bit width bits to an audio sample in the range -1, 1.

roundUpToEven(int x) → int

Rounds x up to the nearest even number.

sampleToInt(double x, int bits) → int

Converts an audio sample x in the range -1, 1 to an unsigned integer of bit width bits.
