pyDAW: A Pragmatic CLI for Digital Audio Processing

Digital Audio Workstations (DAW) are tools for mastering and mixing audio files, in the broader context of large-scale audio processing. Among many other processes, they allow users to perform advanced processes (e.g. Mastering and Equalization) on audio files and apply a chains of audio effects (e.g. Gain, reverb) using sophisticated GUI. DAWs has proven to be a useful resource for Digital Signal Processing (DSP) tasks, and in particular for music production. While the tools are powerful and stable, utilizing tools that require a certain level of knowledge and background in music production and sound processing can be messy and error prone. We propose a solution that allows batch processing of audio file in a fast and prompt manner carrying out some of the popular digital signal processing techniques. The proposed solution, py DAW, is in the form of an open-source tool for users who cannot afford using DAWs for their cost or complexity. pyDAW is a lean Python Command Line Interface (CLI) that provides a simple interface to complement regular DAWs GUI environments, making it easier to run DAWs functionalities in a batch and simple manner.
