flutter_sound_processing 0.1.0

Flutter package designed for sound processing and analysis.

flutter_sound_processing

Flutter library that provides audio processing capabilities, including the calculation of feature matrices from audio signals. It enables Flutter developers to extract meaningful information from audio data, such as Mel-Frequency Cepstral Coefficients (MFCCs) and spectral features.

Usage

To use this plugin, add flutter_sound_processing as a dependency in your pubspec.yaml file using command:

flutter pub add flutter_sound_processing

API Reference

getFeatureMatrix Calculates the feature matrix based on the provided audio signals and parameters.

• signals: A list of double values representing the audio signals.
• sampleRate: The sample rate of the audio signals.
• hopLength: The hop length (in samples) used for analysis.
• nMels: The number of Mel filters to be used in the analysis.
• fftSize: The size of the FFT used for spectral analysis.
• mfcc: The number of MFCC coefficients to be calculated.
• Returns a Future
