Install with pip:

pip install snreval

Build from source

Clone this repository and install the requirements and the Python package:

pip install -r requirements.txt
python setup.py install

Usage

The usage is simple:

from snreval import SNREval

snr_eval = SNREval("/path/to/snreval")

# Either with a single .wav file
df = snr_eval.eval("/path/to/wave/file.wav")

# Or with a multiple .wav files listed in a .txt file
df = snr_eval.eval("/path/to/txt/file.txt")

The result df is a pandas DataFrame with the following columns:

• file: The path of the .wav file
• STNR: The NIST STNR
• SNR: The WADA SNR
