AudioPadType

class fastaudio.augment.signal.AudioPadType(value, names=None, *, module=None, qualname=None, type=None, start=1)

An enumeration.

Repeat

An enumeration.

Zeros

An enumeration.

Zeros_After

An enumeration.

ResizeSignal

class fastaudio.augment.signal.ResizeSignal(self, duration, pad_mode=)

Crops signal to be length specified in ms by duration, padding if needed

SignalShifter

class fastaudio.augment.signal.SignalShifter(self, p=0.5, max_pct=0.2, max_time=None, direction=0, roll=False)

Randomly shifts the audio signal by max_pct %. direction must be -1(left) 0(bidirectional) or 1(right).

NoiseColor

class fastaudio.augment.signal.NoiseColor()

Exponent beta values for named noise colors (see colored_noise).

Blue

int([x]) -> integer int(x, base=10) -> integer

Convert a number or string to an integer, or return 0 if no arguments are given. If x is a number, return x.int(). For floating point numbers, this truncates towards zero.

If x is not a number or if base is given, then x must be a string, bytes, or bytearray instance representing an integer literal in the given base. The literal can be preceded by '+' or '-' and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal.

int('0b100', base=0) 4

int([x]) -> integer int(x, base=10) -> integer

Convert a number or string to an integer, or return 0 if no arguments are given. If x is a number, return x.int(). For floating point numbers, this truncates towards zero.

The literal can be preceded by '+' or '-' and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal.
