What is the difference between cds and records




















With CDs taking up less space and streaming none at all, it is clear that vinyl is the most space-demanding of the trio.

Vinyl is notoriously high-maintenance. If you are willing to put in the effort and time to look after your vinyl properly this should not be a problem, but realistically wear and tear does happen with consequences to your sound performance.

Vinyl is vulnerable to dust, scratches, warping and scuffs which causes problems such as fluctuations in pitch, ticks and pops or can even make the record unplayable. With careful handling, time and effort your vinyl should last for a remarkably long time. Vinyl from fifty years ago still sounds magnificent now thanks to careful owners. The team at Audio Affair can advise you on the best way to look after your vinyl. Co-developed by Sony and Phillips, the CD was launched in with the aim of offering clear and noiseless digital sound.

By CDs outsold vinyl and by billion CDs had been sold worldwide. CDs offered a smaller, digital, more convenient alternative to vinyl. Prefer the clean sound of CDs? The CD was praised for its clear and clean sound reproduction. The CD eliminated the impurities some may say character of vinyl and currently still enjoys superior sound quality to some internet streaming services. CDs enjoy the advantage of being less high-maintenance than vinyl and more reliable than streaming.

While scratches on CDs do affect sound quality, CDs are not as sensitive as vinyl and can withstand more wear and tear. It is argued that CDs lose that authentic character enjoyed by vinyl and instead offer a clinical, cold and thin quality. This is especially the case of older works that were recorded in analogue and have since been digitized. Moreover, because of the act of compression, frequencies are cut and as a result the sound lacks depth. As with most areas of life in the 21st century, the internet is now a music source via streaming services.

The major advantage of streaming is immediately obvious: it is effortlessly convenient and gives you access to practically every song ever made, instantly at your fingertips.

For the price of one CD you can discover a huge range of artists, research new music and curate your library according to your own taste. A digital recording takes snapshots of the analog signal at a certain rate for CDs it is 44, times per second and measures each snapshot with a certain accuracy for CDs it is bit, which means the value must be one of 65, possible values.

This means that, by definition, a digital recording is not capturing the complete sound wave. It is approximating it with a series of steps. Some sounds that have very quick transitions, such as a drum beat or a trumpet's tone, will be distorted because they change too quickly for the sample rate. In your home stereo the CD or DVD player takes this digital recording and converts it to an analog signal, which is fed to your amplifier. The amplifier then raises the voltage of the signal to a level powerful enough to drive your speaker.

A vinyl record has a groove carved into it that mirrors the original sound's waveform. This means that no information is lost. The output of a record player is analog. It can be fed directly to your amplifier with no conversion. This means that the waveforms from a vinyl recording can be much more accurate, and that can be heard in the richness of the sound. But there is a downside, any specks of dust or damage to the disc can be heard as noise or static.

The vinyl record is an analog sound storage medium that is created by flat polyvinyl chloride. Always remember your fingers, towels, and t-shirts are not designed to clean your records or CDs. The playable surface of a CD and vinyl record is made with material that can be easily damaged.

When you touch your records and CDs the oil on your hands will get on them and can damage them or at a minimum attach dirt.

Using a towel or t-shirt will also scratch and damage the surface of the record. If your record or CD needs cleaned it is important to use a soft microfiber cloth to clean them with. Dust is a major enemy of records and CDs. Records and CDs need to be kept free of dust and fingerprints at all times. If you do happen to get your records or CDs dirty you should only use approved cleaners to clean them. Soap and water is always a good option to clean them as well.

Use only those products labeled as a vinyl record cleaner such as DiscWasher cleaner, or use a professional strength record cleaning solution for deep cleaning. Of course keeping them clean is far easier than cleaning them so prevention is always the best thing to do. There are a lot of cases where records were left in a parked car for less than one hour and when they come back found their record warped because of heat.

If you are storing them for long periods of time make sure that the sun never rests on them through the window or door as well. Records warping happens quite often and is one of the main reasons why records get thrown away. If any of your CDs or records get scratched and you are about to toss it. Before throwing it away you should try and fix it. CDs are not affected by surface noise, because they use light beams to read the musical data, which ignore any foreign substance on the disc.

Besides that, vinyl records have an underlying hiss generated by the needle moving over the surface. Mechanical noise. Every turntable, even the most expensive, generates a low-frequency rumble that is transmitted by the stylus into the amplifier and speakers. The system has to work much harder to handle all that low-frequency energy, and that can cause distortion in other parts of the audio spectrum.

Many audio systems include a rumble filter that can reduce this, but that filter also removes the lower-frequency sounds on the record, like the bottom octave of a piano, or the low tones that give a bass drum so much of its power.

Speed variation. Listen to a recording of a solo piano on an LP, and then on a CD. Vinyl depends on a mechanically driven system, and any such system will introduce minute changes in the speed and pitch of playback.

Channel separation. On a CD, the separation between the left and right channels used in recording is over 90 dB. Continuous vs.
