fftea 1.5.0+1

Fast Fourier Transform (FFT) library that can handle inputs of any size. Includes related tools such as STFT and convolution.

1.5.0+1

• Improve example documentation.

1.5.0

• Added an audio resampling util.

1.4.1

• Special case FFTs of size 4 and 5, which are base cases of composite FFT. This speeds up FFTs that hit them by about 10%.
• Small optimisation to primePaddingHeuristic

1.4.0

• Added streaming API to STFT: STFT.stream and STFT.flush.
• Added ComplexArray.createConjugates.
• Added STFT.size.

1.3.1

• Added FFT.indexOfFrequency and STFT.indexOfFrequency.

1.3.0

• Change version constraints to prep for Dart 3.

1.2.0

• Add linear and circular convolution functions.
• Add option to ComplexArray.fromRealArray to truncate or zero pad the array.
• Add a complex multiplication function to ComplexArray.

1.1.1

• Limit FFT size to 2^32, so that int literals can be small enough for JS compatibility.

1.1.0

• Add support for FFTs of any size, not just powers of two.

1.0.1

• Use a bit hack for bit reversal. Speeds up FFT by about 25%

1.0.0+3

• Improve documentation.

1.0.0+2

• Switch to using package:wav in example (fixes a bug in the wav reading).

1.0.0+1

• Improve documentation and add an example.

1.0.0

• Initial version
