Quality Of Sound In Windows 7 - General Intro

Audio or sound as we call it, can be addictive for many, especially for music lovers. You won't believe I spend some 4-5 hours fine tuning my equalizers after a fresh installation of Winamp and Windows Media Player.

While there are equalizers available for WMP and Winamp, there is nothing visible for sound that flows in through browsers. Or is there? I am coming there in a while - how to improve the quality of sound in Windows 7 using Sound Mixer Properties.

Meanwhile, I would like to inform you about the best equalizer for Winamp if you are a music lover. I do not use the default equalizer that comes with Winamp. It restricts the music bands to ten and does not give me features to cut off humming while increase the "tinkles" treble. Normally, ten band equalizers give you a range of 35Hz to 16KHz in form of bars. If you wish to cut off the humming sound, you can't do it using these equalizers.

The best equalizer for Winamp - for local media and for media streaming through the online services being offered by Winamp - is Nevo's 250 band equalizer. Now, that sounds like something. Isn't it? But it is easy to configure. You can draw free-form curves or use line adjustment. I guess it is the best equalizer for Winamp. You can just search for "Nevo Equalizer" to get the plugin.

The above was a little off topic as we are to talk about how to enhance the sound quality in Windows 7.

Enhancing The Sound Quality in Windows 7

There are many factors that come into play when you really wish to improve the quality of sound in Windows 7. Some of them are:

1. Are you willing to invest money in speakers

2. Are you willing to replace or buy a better sound card

3. Are you willing you install additional codecs and

4. In case you opt for none of the above, there is still scope to improve bass and reduce noise in Windows 7 sound/audio - whether it is local media or streaming media like radio or YouTube.

Know What You Are Buying - 2.1 vs 2.0 Speakers

There is no doubt better speakers provide a better sound. If you wish to invest money in speakers, buy the ones that are minimum 50W+35Wx2.

If you are buying a 2.1 speakers, there is a catch most salespeople won't tell you. In fact, when you ask for a 2.1 set, there should be separate line for the sub-woofer. In average systems, the sub-woofer draws its sound from the lines of satellite speakers. That is, if a system is really 2.1, you will get three lines instead of average two.

Keep that in mind while buying. Check out the package to see how the output is mentioned. It should be 000W+000Wx2 for a good 2.1 speaker set. In this case, they are specifying that the sub-woofer has its own line with whatever output (replace that number with 000 mentioned here). Same way, satellite speakers are each of some strength. I recommend a minimum of 35W for a small to moderate sized room.

Anyway, considering you don't wish to invest money at this stage, there are some other methods that we'll check out.

Using Sound Properties Dialog To Fine Tune Audio in Windows 7

This method allows you to improve sound quality in Windows 7 as it lets you enhance bass and adjust the loudness counter.

To enhance the quality of audio:

1. Right click on the Volume icon;

2. Select Playback Devices;

3. In the dialog box that appears, select the Default Speaker set (there may be more than one depending upon your sound card and software installed)

4. Click on Properties;

5. Click on Enhancements tab

6. Click to select Bass Boost and click Properties. I will divide bass into two types: drum bass and harmonic bass. The latter is the one produced by those huge guitars that add real bass to music.

6.1 If you want drum bass and harmonic bass both, select 80Hz and increase the dB to anywhere between 9dB to 18dB. You can increase it more but then, the other sounds - including human voice and treble will go down drastically. You can then select Loudness and then set up the slider to one or two places away from Short. You will need to experiment a little before you hear the proper sound clarity. If you are making changes even as your browser is streaming audio, you have to refresh the page (press F5) to apply changes.

6.2 If you just want harmonic bass and wish to avoid the humming sound that is created by frequencies lying between 50 and 60, select 50Hz and increase it by 12-18dB. Then, use the Loudness properties to fine tune the audio. In my case, it is 50Hz at 15dB with loudness slider set to Short.

I also created a video to demonstrated the process. Since I created it in a hurry due to running late on my schedule, it does not contain step by step narration but after reading above, it should be enough to show you how to go about fine tuning audio in Windows 7.

If you still face any problem or wish any kind of assistance with setting up audio in Windows - any version, please contact me at or via

NOTE: There are some third party global equalizers available for Windows 7 that claim to enhance the quality of sound in Windows 7 or any other version. I tried few of them and they are not as satisfactory.

One of them can be recommended but is a little tough to configure. If you wish to check it out, download Equalizer APO. But make sure you create a system restore point before playing with the configuration files of this equalizer. It may take time but if you understand how to use it, it is the best option to improve the quality of sound in Windows 7.

    We are talking about global EQ for Windows. The above link by Himanshu just tells you how to use the equalizer in VLC. Am pretty sure anyone who listens music on his/her computer already knows how to use equalizers. I myself use a 250+ band EQ for Winamp -- after a global increase of 50Hz by 21dB for streaming music/video.
