Every real life sound that the human ear is capable to perceive, leaving artificial sound sources aside, are referred to being ?analog’. Essentially, analog audio stands for an analogous recording of sound, made by capturing and imprinting natural soundwaves on audio tape or other dedicated devices. Regardless of the means used for capturing analogue sound, all analogue recordings either store the incoming signal as a continuous sound wave or on the media.

Digital audio recording works by turning the originally captured sound into a numeric sequence, which is subsequently sampled to provide a digital representation of the analog sound signal. The term sampling denotes the division of sound signal into separate intervals (for instance, the sample rate of common CDs is 44.1 thousands of samples/ second). While CDs come with a 16-bit sound resolution, DVD-Audio discs allow higher resolution encoding, sometimes up to 24-bits. Therefore, DVD-Audio discs provide superior bit depth compared to their CD counterparts, providing a quality that closely resembles that of analog recordings.

To keep things simple, the main difference between analog audio and digital audio consists in the nature of the sound waves. While analog recordings are continuous in time, digital recordings are obtained through a process of sampling at distinct intervals.

It wouldn’t be wrong to say that digital audio is by far more complicated to achieve than its analog counterpart, but it has the merits of keeping noise at a low threshold, allowing for better duplication capabilities and offering higher speed accuracy.

Although modern technology evens out the gap between digital audio and analogue audio, sometimes the differences in these two types of sounds are perceivable. A trained ear can make the distinction between the two, and many audiophiles stand by the claim that analogue audio recordings have more of a real feel to them, giving the impression that you are actually hearing music that is played live.

The advantage of digital audio is that it eliminates or at least limits analog recordings-specific distortions, but lacks significantly in terms of analog-to-digital and digital-to-analog conversion possibilities. Moreover, many audiophiles and recording specialists perceive digital sound as cold and artificial, as it lacks the organic dynamic of analogue audio.

Overall, the analog vs digital battle is an equally balanced battle, as it is difficult to come up with solid, objective arguments to indicate a clear winner. Although digital audio is everywhere these days, and has the advantages of being cheaper and more convenient, analogue comes in strong from behind by allowing listeners to experience a genuinely life-like sound. Moreover, analogue recordings are apparently back in fashion, with a growing number of audiophiles saying no to digital and turning instead to the organic sound of old school vinyl recordings.

Hifi – or high fidelity – audio systems are capable of offering the best level of sound quality possible. Available models can range anywhere from basic systems delivering high quality sound reproduction (but which lack in terms of audio filtering), all the way to complex hifi audio amplifier systems that include sound editing options, surround sound, and many other cool features. At present, audiophiles are benefited with a better costs-for-quality balance, which means one doesn’t have to spend top dollar to get a genuinely high quality performance.

Hifi audio systems can be separated into three distinctive groups: micro, mini and midi, with the latter category being the most popular. Each of these types of systems can include additional features like multiple disk playing and can allow for a variety of control options. Hifi audio amplifiers are also available in the next size down, which has an equivalent list of features, but with a significantly smaller footprint. In general, micro hifi audio systems are smaller-sized and offer weaker output capabilities, but on the flipside they are easier to carry around and score extra points in terms of convenience in case you live in a small, crowded apartment.

What you should keep in mind is that irrespective of the size of the hifi audio amplifiers or complete sound systems you prefer, you should generally use their price tags as an indicator of their performance, durability and reliability. That said, stay away from systems with unrealistically low prices and consider opting for reasonably priced options instead. Numerous trustworthy brands provide a wide range of competitive products, some of which also provide support for multiple playable formats. Most hifi audio systems are compatible with MP3 encoding and other newer generation digital music formats, while also allowing you to play the traditional formats.

Every sound system available in the market comprises a playback device, a set of hifi audio amplifiers, and a couple of quality speakers. While you can use such audio systems just for listening to music, with a suitable setup, you can easily connect them to your home theatre for an ultimate sound and multimedia experience.

For best sound clarity and volume output, consider purchasing ‘the complete package’ – which generally includes tweeter, bass, mid-range speaker and subwoofer. Since a competitive hifi guide audio amplifier and a quality disc player also require a set of good speakers to unleash their true power, if you want to wrap up an impressive sound system, don’t be too cheap when buying your speakers. The good news is that with the technology advancements of late and with the current diversity in terms of available models in the market, hifi sound component prices have started to even out, which means you can put together a state-of-the-art home audio system without burning a hole in your budget.
