# Recompress Audio (RCA)**The Problem**: If you recompress lossless audio for use onspace-sensitive devices such as a cell phone or Raspberry Pi, then RCAcan help you re-compress those lossless tracks whenever improvedversions of your codec are released or when you change your desiredencoding settings.It does this by keeping track of the encoder's version and flags used ina simple text file that resides along-side the audio.You can also characterize your tracks as speech or music, stereo ormono, simple or complex (amung others), which RCA uses to tailor theencoding flags and bitrates.RCA is simple to use, command-line driven, and doesn't require anychanges to your directory layout or audio filenames.## How it WorksYou characterize a given directory audio tracks by populating a new`properties.yml` file with something like the following:```yamltracks: type: music complexity: moderate channels: stereo ```The above tells RCA that all tracks are stereo music of moderatecomplexity.Here's a more complex example of a CDs having music, commentary, soundeffects, and two trailing filler track of dead-air:```yamltracks: type: music complexity: simple channels: stereotrack03: type: effects complexity: moderatespeech: range: [4, -, 9, 12] complexity: complex channels: monofiller: range: [13, 14]```The above tells RCA that:- tracks 1, 2, 10, and 11 are *stereo music* of *simple* complexity- track 3 is *stereo* sound *effects* of *moderate* complexity- tracks 4, 5, 6, 7, 8, 9, and 12 are *mono speech* of *complex* complexity- tracks 13 and 14 are fillerYou then run RCA while specifying your desired output codec, such as`rca opus`, which encodes the tracks according to the Ogg Opus profiles,which can be customized.## Getting Started1. Install Python 3.5 or preferably the latest, which is currently 3.7.x - Windows users: enable the *Add Python to your PATH* option during install2. Install RCA: open an command prompt as the Administrator (Windows) orroot on Linux/OSX) and run `pip3 install rca`
