STFT class
Performs STFTs (Short-time Fourier Transforms).
STFT breaks up the input into overlapping chunks, applies an optional window, and runs an FFT. This is also known as a spectrogram.
Constructors
- STFT(int chunkSize, [Float64List? _win])
- Constructs an STFT object of the given size, with an optional windowing function.
Properties
Methods
-
flush(
dynamic reportChunk(Float64x2List)) → void - Runs STFT on any remaining input in the buffer.
-
frequency(
int index, double samplesPerSecond) → double - Returns the frequency that the given index of FFT output represents.
-
indexOfFrequency(
double freq, double samplesPerSecond) → double - Returns the index in the FFT output that corresponds to the given frequency. This is the inverse of frequency.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
run(
List< double> input, dynamic reportChunk(Float64x2List), [int chunkStride = 0]) → void -
Runs STFT on
input. -
runAndCopy(
List< double> input, [int chunkStride = 0]) → List<Float64x2List> -
Runs STFT on
input. -
stream(
List< double> input, dynamic reportChunk(Float64x2List), [int chunkStride = 0]) → void -
Runs STFT on
input. -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
