octafilt3r is a python module for continuous signal filtering with fractional octave filters. It is able to generate non-FFT-based spectrograms, which can be used for machine learning. Despite their low resolution, the spectrograms capture the most important characteristics of a sound. This makes them suitable for applications with low data troughput |
- Transform an audio signal into its frequency bands without an FFT
- Generate spectrograms
- Apply A-weighting (audio only)
