aproc

aproc

A script for processing and performing QC on audio files.

Prerequisites

In order to use all of the script's functions you will need to have the following programs installed: ffmpeg, ffprobe, SoX, BWFMetaedit, Mediaconch, poetry

Usage

In the terminal, navigate to the nul-rdc-scripts folder before running.

Note: make sure valid inventory csv is in the input folder
Note: qc_log is always generated (mediaconch policies are always checked)

Basic usage

poetry run aproc -i INPUT_PATH -a

Generate spectrograms

poetry run aproc -i INPUT_PATH -s

Only generate qc_log

poetry run aproc -i INPUT_PATH
