audioFlux
audioflux
is a deep learning tool library for audio and music analysis, feature extraction. It supports dozens of
time-frequency analysis transformation methods and hundreds of corresponding time-domain and frequency-domain feature
combinations. It can be provided to deep learning networks for training, and is used to study various tasks in the audio
field such as Classification, Separation, Music Information Retrieval(MIR) and ASR etc.

Table of Contents
Overview
audioFlux
is based on data stream design. It decouples each algorithm module in structure, and can quickly and
efficiently extract features of multiple dimensions. The following is the main feature architecture diagram.
You can use multiple dimensional feature combinations, select different deep learning networks training, study various tasks in the audio field such as Classification, Separation, MIR etc.
The main functions of audioFlux
include transform, feature and mir modules.
1. Transform
In the time–frequency representation, main transform algorithm:
-
BFT
- Based Fourier Transform, similar short-time Fourier transform. -
NSGT
- Non-Stationary Gabor Transform. -
CWT
- Continuous Wavelet Transform. -
PWT
- Pseudo Wavelet Transform.
The above transform supports all the following frequency scale types:
- Linear - Short-time Fourier transform spectrogram.
- Linspace - Linspace-scale spectrogram.
- Mel - Mel-scale spectrogram.
- Bark - Bark-scale spectrogram.
- Erb - Erb-scale spectrogram.
- Octave - Octave-scale spectrogram.
- Log - Logarithmic-scale spectrogram.
The following transform are not supports multiple frequency scale types, only used as independent transform:
-
CQT
- Constant-Q Transform. -
VQT
- Variable-Q Transform. -
ST
- S-Transform/Stockwell Transform. -
FST
- Fast S-Transform. -
DWT
- Discrete Wavelet Transform. -
WPT
- Wave Packet Transform. -
SWT
- Stationary Wavelet Transform.
Detailed transform function, description, and use view the documentation.
The synchrosqueezing or reassignment is a technique for sharpening a time-frequency representation, contains the following algorithms:
-
reassign
- reassign transform forSTFT
. -
synsq
- reassign data useCWT
data. -
wsst
- reassign transform forCWT
.
