Description:
tifresi 0.1.4
tifresi: Time Frequency Spectrogram Inversion
'tifresi' to be pronounced 'tifreeezy' provide a simple implementation of TF and spectrogam suitable for inversion, i.e. with a high quality phase recovery.
The phase recovery algorithm used is PGHI (phase gradient heap integration).
Installation
This repository use the ltfatpy packages that requires a few libraries to be installed. The package relies on some library that have to be installed beforehands.
Install fftw3, lapack and cmake
On debian based unix system:
sudo apt-get install libfftw3-dev liblapack-dev cmake
On MacOS X using homebrew:
brew install fftw lapack cmake
On MacOS X using port:
sudo port install fftw-3 fftw-3-single lapack cmake
Install cython (required for installing ltfatpy):
pip install cython
Install the package from pypi
pip install tifresi
or from source
git clone https://github.com/andimarafioti/tifresi cd tifresi pip install .
Starting
After installation of the requirements, you can check the following notebooks:
demo.ipynb illustrates how to construct a spectrogram and invert it.
demo-mel.ipynb illustrates how to compute a mel spectrogram with the setting used in this repository.
