I've always found the world of python packaging and environment management to be somewhat confusing.
Here are some notes that I hope will remind me how it works when I forget.
N.B. I have focused on Pipenv and Pipfile in this article, as they are the latest and greatest way of managing project
environments, but the same principles apply to older workflows using virtualenv, pip and requirements.txt.
SoX is a great tool for converting and processing audio. As an engineer working at a radio station I find it especially useful for processing audio files so the volume is even and smooth throughout. A recent use case was preparing news bulletins recorded by a non-technical journalist so they sounded clear and loud for an Amazon Alexa skill.
What is an AGC?
Automatic Gain Control (AGC) is an audio processing technique that is designed to smooth out volume differences between different parts of an audio programme. The majority of radio stations will have a device at their transmitter (for example, an Optimod) that does just that. Parts of the broadcast that are two quiet are boosted and parts that are too loud are atenuated.
