        <summary>Hard Drives and Linux

Linux does hard drives astonishingly well. So well, in fact, that most hard drive rescue services default to Linux because its toolset is so rich.

TL;DR 

If you do not want to go into hard drive forensics for a living, you may be most interested in:

        <summary>SoX

SoX is an audio converter and mixer. It's a handy command for quick conversion tasks, and possibly for scripted audio editing.

SoX reads and rewrites audio data. 
Whether it stores the rewritten audio data is up to you.
There are use cases in which you don't need to store the converted data, for instance when you're sending the output directly to your speakers for playback, or directly to another command through a UNIX pipe.</summary>

        <summary>JACK

TL;DR 

You should install Jack2 if you intend to use audio or video creation applications on Linux.

If you have any experience with traditional professional audio hardware (synthesizers, effects, mixers) or even professional networking gear (routers, switches, vlans), then you are accustomed to the notion that signals must be routed from one place, through a filter of some sort, to a target, and then perhaps through another filter, and then a final destination.</summary>

The parecord (“Pulse Audio record”) command is a tool that lets you record anything passing through your system's sound system. You can use it to record streaming music, Internet radio interviews, sound effects, and anything else your computer is playing at any given moment. If you can hear it through your computer speakers, you can record it.</summary>

        <summary>Understanding Linux Audio

TL;DR 


	* Identify Physical Devices
	* Identify Sound Cards
	* Map Sound Devices to their Controls
	* Set Up Kmix

Traditional Linux (such as Slackware, and as opposed to something more progressive like Red Hat and Fedora) deals with audio in its own unique way. This can be confusing to new users, or to experienced users who have never thought about it. It confuses people because almost no where in the audio schema is there a one-to-one mapping; you must think of aud…</summary>

        <summary>Pre-Installation

The first step in creating Slackermedia is to install Slackware and configure it for your machine. It is strongly advised that a user be familiar with GNU, Linux, BSD, or UNIX before attempting to build a Slackermedia system. However,
it is hardly unheard of (and in fact, arguably best) for someone to start their Linux journey with Slackware. This chapter guides you through the install process and highlights potential points of confusion.&lt;a name=&quot;preinstall&quot;&gt;&lt;/a&gt;</summary>
