5.1 Surround Experince


When music is associated with everybody's life , why not make it little more Awesome.....


The purpose of this article is to provide general user with a better acoustic experience over the experience of compressed audio playback.
The article will guide you to setup the required software and settings to achieve surround sound from your stereo setup using free and open source software.

DO I REALLY NEED IT ?

The problem at hand is most audio files are Stereo , and even with a dedicated 5.1 Audio system without some investment for upmixing , we are able to hear normal. And for people who don't have a Home Theater system, why to restrict them from Surround experience. A disappointment for both.

After much research, I came up with a solution that not only solves both problem, but also enhances MP3(or any other compressed formal) audio to near ORIGINAL quality.
 
I May not be the best person to answer, if You really Need / Want it.
Simply download and experience it yourself with the sample files
First file is 'Sun Willow' by  Bjorn Lynne in Original Dolby Digital 5.1 format
and the second file is Surround sound version, processed using this guide.

If You really felt the difference, please go ahead with this guide.
Don't worry, if u are not a technical person, this guide is for just for you people.

UPDATE: fixed broken sample file link

 

Stereo and 5.1 Audio

Stereo audio is comprised of two channels basically Left and Right.
The Mp3 files are mostly stereo, but there quality is compromised for achieving lower file size.
-Wikipedia


5.1  ("five point one") is the common name for six channel surround sound multichannel audio systems. 5.1 is now the most commonly used layout in both commercial cinemas and home theaters. It uses five full bandwidth channels and one low-frequency effects channel (the "point one").-Wikipedia

 

Required Software

Now the idea is to upscale the stereo audio to recover quality, lost due to compression.
We are going to do this using ‘ffdshow’, a powerful audio decoder with some additional abilities.
By now you would have started to think of it as another media player, but fact is it is not.
Like in a car there is engine and body covering, here ffdshow works like the engine and for the body cover we would use an actual media player, in this case ‘Media Player Classic-Home Cinema’.

Now installing software is not a rocket science, but doing it right is important for optimal performance. And don’t be scared of installing two different software and managing them. It is already combined and freely distributed under
K-Lite Codec Pack’ .Which means it is the only software we need.

K-Lite Codec Pack download       : http://www.filehippo.com/download_klite_codec_pack/12665/


Configuration file                             : ffdshow_8_8.reg



Detailed installation guide                : K-lite 8.8 setup.docx

UPDATE : links are restored.

Installation

Here comes the tricky part the INSTALLATION, don’t worry this guide is here this purpose only.
Simply follow the instructions in the installation guide.

The setup looks good and will work as well, but the Surround sound is still missing.
To make this task a child’s play all the configurations have been saved in provided file.
Now double click on the ffdshow_8_8.reg file you would have downloaded, keep click yes until below window appears.

And you are now all set to enjoy Surround sound from your audio files.

NOTE:
1.            Close the installer or Media Player Classic before installation.(!! IMPORTANT !!)
2.            In some cases the configuration file may be downloaded as a MP3 file. Solution - rename file and delete ‘.mp3’ extension from filename

 

Final Touch

One size doesn’t fit all, as the saying goes is true for us also. The default setting in file will work fine most PCs.
The configuration adds multiple audio enhancement profiles with varying level of Processor load and audio output.
To access these profiles
Right Click inside the MPC window -> Filters -> ffdshow Audio Decoder -> Properties

You will get a window like screenshot shown below.


 OR

Under your Windows taskbar icons find the ffdshow icon > right click

 
Simply click on the profile name to activate from list.
