Continuing the series of articles on how to become a YouTuber, today I will address some more tools for the production of gameplay videos. All the programs mentioned here are in the PCLinuxOS repos.
Audacity is a free digital audio editing software available mainly on the platforms Windows, Linux and Mac and also on other operating systems. The source code for Audacity is under the GNU General Public License. Its graphical interface was produced using wxWidgets libraries. The Audacity project started in 1999 by Dominic Mazzoni and Roger Dannenberg at Carnegie Mellon University in the U.S., and was released on May 28, 2000 as version 0.8.
Audacity is very popular with podcasters for its editing features, its wide availability on multiple platforms, its support, and its open license that enables the program to be free.
On October 10, 2011, it was the 11th most popular download from SourceForge, with 76.5 million downloads. Audacity won the SourceForge Community Choice Award in the 2007 and 2009 contest's for Best Multimedia Project. In March 2015, the hosting was moved to the FossHub site, and in February 21, 2017, it exceeded 51.8 million downloads on that platform.

The main tools we'll use are as follows, as found in the Effects menu:
- Normalize: Use Normalize effect to set the peak amplitude of a single track, making various tracks have the same peak amplitude and equalize the balance of the left and right channels of stereo tracks. Optionally, you can remove any DC offset of the tracks.
- Amplify: Increases or decreases the selected audio volume. When you open the dialog, Audacity automatically calculates the maximum amount you can amplify the selected audio without causing cuts (distortion caused by trying to do the very high audio).
- Click removal: Removal of clicks is designed to remove clicks in audio tracks and is especially suitable to decode recordings made of vinyl records. Usually it works best with very short clicks. For larger individual pops selections in width up to 128 samples (about three milliseconds to a 44100 Hz design rate), you can try the repair effect.
- Noise reduction: Reduces the noise of constant background, as fans, tape noise or ringing. It will not work to remove background conversations or music.
Remember: to use Audacity comfortably, you should create a folder /TMP for your temporary files. Do not use the /tmp of the system, or it may be unable to edit your audio tracks.
jPSXdec is a media converter of the PlayStation 1 platform that produces higher quality output compared to all other legacy converters.
Advantages of this program over existing converters programs
- Can decode some unique types of films
- Converts with correct colors
- More precise frame rate detection.
- Multi-platform (Windows, Mac, Linux)
- Source code available
Also has features for modders: replace STR video, replace audio XA and replace Tim pictures.

With this program, you can extract audio (songs), videos and images (.TIM format) from Playstation 1 ISO's. This makes it possible to enrich your videos of gameplays, with the videos of the game, without having to play it for them to be played.
Rezound aims to be a stable audio file editor, open and graphical code, especially for, but not limited to, the Linux operating system.
It does not have all the features of Audacity. However, for certain tasks, it is the most appropriate. It is faster, and it has an interface with very interesting tools (like a slider button to search for a particular passage in an audio file).

Some of its features:
- A 16-bit or 32-bit floating point integer can be chosen as the sample size
- Fast editing of large files
- Signaling Positions labeled
- Suggestions can be dragged
- Crossfading automatic selection borders in all actions applied to create smooth transitions
- Ability to save user notes in formats that support it.
- Macros allow a user to record one sequence in a file and repeat these actions in other files later.
- User defined key links to actions
- Support LADSPA Plugin's
- Various effects / manipulations
- Change volume
- Gain (by steady or curve)
- Change rate (for constant or curve)
- Delay (echo)
- Distortion (for a curve)
- Repeat varied
And so, we finish another article of this series of producing videos to YouTube. I hope you enjoy, and next month there's more.
