The stereophonic effect, even on the corresponding equipment, appears only if the phonogram is also stereophonic. But there is also a way to get surround sound from a monophonic phonogram, and to enrich the sound of a stereo one.
Instructions
Step 1
Before physically altering your audio system, check for surround sound settings in your computer's sound card settings. The interface for these settings varies greatly from card to card. It is often possible to obtain pseudo-quadraphony with only two speakers, as well as simulate reverberation in concert halls of various sizes, in open spaces, etc.
Step 2
If the sound card or its software does not support the surround sound setting, try connecting a special device - a reverb between the computer and the speakers. You will feel that the music is playing in a much larger room than your room.
Step 3
Try to make a pseudo-quadraphonic set-top box to your computer speakers. Take very small active speakers with an output power of about two watts. Disconnect them from the network and from the computer. Disassemble each one. Take two 1uF paper capacitors and connect one in series with each speaker. Connect a long cord in parallel with the speaker / capacitor circuit. Redesign each of the speakers in this way, and then close them back, first making a hole for the cord and bringing it out. Make sure that newly added items do not touch other speaker circuits, especially network circuits.
Step 4
Take large speakers like those that come with domestic turntables. They must have a resistance of 8 ohms. Connect to the opposite end of each of the cords you connected in the previous step over that speaker.
Step 5
Place small speakers in front of you and large speakers behind you. Connect the converted active speaker back to your computer and to the network. Make sure it works properly.
Step 6
Experiment. The proposed arrangement of the speakers in relation to the listener and each other is not the only possible one. Try by rearranging them to achieve a more pronounced pseudo-quadrophonic effect that works best for you.
