Vinyl myths

Vynil myths

The idea of ​​a “vinyl renaissance” arose after the first disappointments with the then imperfect digital technologies. People were taught that the sound of CDs contains only a fraction of the information about the original analog signal (which is absolutely true), and this should be offensive to the ears of true connoisseurs of music.

The Sound of Vinyl

The audiophile code says: if you want real sound, forget about the “dead number” that cuts the sound into pieces, a week warm up the amp and use solid gold connection cables. It is believed that if you digitize a disc with a frequency of several megahertz, you can preserve its “live analogy” and “sound warmth” inaccessible to CDs. For more drama, below is an audio selection of statements by famous and well-respected people on their ideas on sound and on the now-in-fashion “vinyl” theme.

Acoustics, like any other field of knowledge, has developed its own system to measure the characteristics of sound, based on the laws of physics. Audiophiles argue that you should listen to music with your ears, not with an oscilloscope. I agree that the “musicality” of the sound does not always depend directly on the technical characteristics. For example, the effect of thermionic emission in vacuum, in contrast to the movement of electrons through a semiconductor, has linear characteristics and a predictable behavior of the amplified signal. Due to saturation with uniform harmonics, the sound takes on a pronounced color tone, causing the “recognition” effect of musical instruments. Therefore, a tube amplifier, despite the worse characteristics compared to a transistor one, may subjectively sound better. With the help of modern technology, sound can not only be heard, but also seen. A direct visual comparison of the characteristics of different formats will help answer many questions.

As for the connecting cables, which are two electrical conductors, welded symmetrically at the ends, the audio-frequency alternating current moves along them equally in both directions. Since all analog and digital cables are passive conductive elements, that is, they do not have a signal amplifier, then there is no difference when connecting them in either direction.

The gramophone disc format in its current form appeared in the 50s of the last century. Thanks to the use of a new polyvinyl chloride (vinyl for short) made of plastic and fine-grained material, the rotational speed of the record was reduced from 78 to 33 rpm and the width of the track, from 0.14 to 0.055 mm. At the same time, the playback time has increased eightfold and the sound quality has increased dramatically. The name Long Play (LP) is firmly established for the new full-length format. The phonogram is preliminarily subjected to amplitude compression so that the dynamic range matches the properties of the vinyl. This process is called mastering. Then a master disc is recorded, which is a solid aluminum base to which a thin layer of nitrocellulose varnish is applied, on which a soundtrack is formed with the help of a sapphire cutter. Then, through intermediate stages, the plates are printed using high pressure at high temperature. A press die can make 500 to 1000 copies, after which the sound quality drops. Not in vain does the term “first impression” exist which, depending on the point of view, can be interpreted as a successful copy of the disc, or as an instability in the reproduction of the final result.

The nature of sound is such that the energy of the low frequencies is much greater than that of the high ones. To convince yourself of this, simply compare the magnitude of the travel of the woofer and tweeter cones. During playback, the difference in sound pressure levels at the edges of the frequency range exceeds 50 dB, which corresponds to 400 times the amplitude ratio of the lowest and highest sounds. Taking into account the short-term signal peaks, this value can reach several thousand. The record’s microscopic soundtrack isn’t capable of conveying a great dynamic range, and mastering alone isn’t enough here. The signal level at the lower limit is close to the noise of a vinyl base, whose grain structure is comparable in size to the high-frequency vibrations of the soundtrack, which can distort the sound.

To reduce the spread of amplitudes, frequency correction is applied during recording of the master disc: low frequencies are attenuated and high frequencies are amplified, the crossover point is the frequency of 1 kHz. In this case, the difference in pressure levels.

Is Vinyl Sound Better Than Digital Audio Formats?

Is Vinyl Sound Better Than Digital Audio Formats?

Vinyl vs Digital

True music fans want the best sound quality for their favorite albums and recordings, and with the return of vinyl, the debate over which is better (CD versus vinyl, digital versus analog) has only sharpened. Many people value vinyl not only for its clean playability and lack of digital sound processing during playback, but also for the very process of installing the record on the turntable and the ability to hold the record in your hands.

Vinyl Vs. Digital

Nowadays, it is possible to play tracks as often as musicians record them. They record music at frequencies above the standard 44.1 kHz (96 kHz or 192 kHz) CD recording rate for better sound quality. Many people in the audio industry say that they can see a noticeable improvement in quality with higher sample rates than CDs, which is why they prefer listening to high-resolution music.

When turntables take priority over other formats

There’s a reason the vinyl revival has taken place. Yes, there is a certain appeal when you can hold a recording in your hands, which is different than choosing digital tracks on the screen. But there is also the argument that vinyl sounds better than digital recordings, exactly as the musician intended. The main difference between a vinyl record and a CD and MP3 is that the record on the record is analog. It is a physical recording, represented by a continuous electrical signal that reflects a change in the sound wave that is fully consistent with the original sound.

Unlike vinyl, most digital formats are compressed during recording and playback to minimize file size, making it ideal for various devices and can easily be streamed over the Internet. Most streaming services simply won’t be viable without audio compression technology.

When compressed, audio files lose not only size but also sound quality. This means that the listener loses the smallest sound details that the musician wanted to convey when he recorded this track. For the average listener this may not matter, but for music lovers, losing this depth of sound is completely unacceptable.

However, in both cases, analog or digital, good sound always begins with a good recording and how the sound engineer created it. If mistakes were made from the beginning, this cannot be corrected during playback.

Vinyl provides a warmer, livelier sound

Vinyl fans always talk about the “warmth” they get from classic recordings. This is not nostalgia, but a very real sonic phenomenon. According to sound engineer Adam Gonsalves, vinyl provides a more pleasant and warmer sound to your ears. This is especially noticeable when listening to classic rock artists like the Beatles, Led Zeppelin or Pink Floyd.

In the 1990s, record labels struggled to make their records stand out from the rest. To do this, the sound was processed and compressed with special programs for greater saturation. But this digital sound processing not only increased the volume, it also noticeably spoiled the sound quality. Compared to those processed tracks, vinyl is just so much cleaner and better.

When digital formats win

There is an important caveat that vinyl sounds better in certain but not all circumstances, especially when modern music is digitally recorded in the studio. In this case, albums released on vinyl and digital have little or no difference in sound quality between them. In addition, there are high definition digital audio formats and SACD (Super Audio CD) formats that surpass vinyl in sound quality.

In terms of convenience, digital formats outperform vinyl. Streaming music from your smartphone or mobile device is infinitely easier and more convenient than putting on a disc and flipping the disc every three to four songs.

Ultimately, it is up to each listener to decide what is most important to listen to: the high sound quality of vinyl records or the convenience of digital formats.

If you want to hear your favorite classical composers in exactly the way the musicians and sound engineer wanted to convey it, vinyl is made for you. Be sure to check out today’s Denon turntables, amplifiers, and other hi-fi components to begin your journey to real sound.

Audio quality

MP3 generation: today they are young. The most famous digital music format of all time is in people’s mouths and ears, targeted by piracy, and on portable players around the world.

Bitrate

Meanwhile, vinyls have become relics in used bookstores and K7 tapes are left behind in the closet. In fact, it’s not surprising that many of today’s youngsters have never had the pleasure of listening to a good vinyl record on an old record player.

Digital music formats are everywhere and make the soundtrack of every user’s life. But then, do you know how to take advantage of available audio technologies or any MP3 file, regardless of quality, is a good size for your ear?

Bitrate

No matter your musical style, the audio quality in digital music is of great importance. Each format, each size, each file has a different quality and this directly influences how a song is heard.

Find any music CD in your drawer and put it to play on your radio. Now choose an MP3 and listen to it on your computer speakers. Did you notice the difference in noise and compression?

Quality, format and compression.

To transfer songs from an audio CD to your computer, there may be no loss of quality to your music? Quality if you use the WAV (Windows standard) or AIFF (Mac standard) format. The quality is perfect, but the size can give you a big headache: for every minute of music in WAV format, an average of 10 MB is taken up on the hard drive.

So to take up less space, use an audio file compressor like Free MP3 Converter and end up with a low quality, compressed size audio file. How does MP3 get so much smaller? The format basically removes all audio tracks that, in theory, are not perceived by the human ear, compressing instruments and layers of music.

It is as if a steamroller passes over an orchestra: the music sounds like a block of noise, which can cause hearing fatigue. The big problem is that people are so used to this mass of instruments and voice that music is at serious risk of degradation.

Bit rate (bit rate)

An encoded or decoded file is never exactly the same as the original file, as much of the information deemed superfluous is removed. In general, the lower the compression ratio, the better the quality of the file.

The term used to speak of compression is Bitrate, it consists of the average number of bits that in one second of the data will be compressed. The unit used is KBPS or 1000 BITS per second. Check the audio quality below based on the bit rate used.

Vinyl, CD or files: Who wins this historic clash?

We analyzed the difference and the peculiarities of both CDs and vinyl, reaching a controversial conclusion: vinyl is great, but it is not better than CD.

vinyl vs digital

The return of vinyl has been celebrated around the world, it is a large format, nostalgic, but when it comes to sound quality, there are many steps behind the CD. There is no way to compare something analog with something digital. What can be discussed is the quality of the artists of today, in relation to the artists of the past.

If Led Zeppelin recorded his self-titled album today, digitally, it would be even better when it comes to sound quality. Just as if Justin Bieber recorded “Believe” in the past, similarly, it would be even worse.

In addition to vinyl and CDs, other music distribution formats are also in vogue, such as MP3.

Advantages and disadvantages of vinyl:

vinyl

On vinyl, sound waves are analog, as is vinyl recording. This means that there is not much loss between recording and playback. Many claim that vinyl sound has more body and shows more detail. Since it is an analog process, the EQ naturally has more bass, making it more noticeable.

However, this does not mean that the sound is of higher quality. If the CD has a sample rate of 44 KHz at 16 bits, the vinyl would have 16 KHz at 8 bits.

Vinyl is physically limited in some way. First, in terms of “dynamic range”, which in the case of vinyl is extremely limited.

(Note: Dynamic Range is the difference between the highest note and the softest note.)

And secondly, in terms of “frequency”, because the quality of vinyl’s frequency is not universal, it is variable.

The sound of vinyl sounds better on songs with lower notes, because if the notes of the songs are too high, the needle has difficulty following / playing, which contributes to significant distortions in the sound of the songs. For example, try listening to the letters, whose consonants (s, z, etc.) are sung sharply, the distortion will be clear.

Because they have more groove and clearer, cleaner bass, the vinyl is a favorite for music djs.

Advantages and disadvantages of the CD:

CDs depend on sampling an analog signal, as well as having some limitations regarding the “frequency” element. While on vinyl, encoding is done in an audio waveform, on CD, this audio sampling encoding must be captured in different ways and points, unlike vinyl, which captures it through a single point, for what cd will never be able to present the rhythm that vinyl presents, and this is one of the few advantages of analog over digital.

On the other hand, the CD has a sufficient sampling volume to sound clearer and more defined to the human ear.

The sampling rate of CDs is 44.1, which means that CD recordings can be captured up to 44,100 times per second and can capture frequencies of 20KHZ.

And this frequency is the maximum that the human ear can hear, the human ear is clear, because in the case of dogs, for example, it is still a low frequency, because they have a hearing 4 times higher than ours, and probably even listen to our breathing clearly.
.

Recordings above 21 kHz, only for dogs. This does not mean that the 20 Khz reached by the cd is worthy of an outstanding frequency, no, it is not that the frequency of the cd is clearer and clearer to the human ear.

Also, in the recording studio there is no microphone to capture more than 20 Khz.

MP3:

digital audio

It all depends on your compaction rate. MP3, like CDs and DVDs, captures sound waves and converts them to files. It turns out that in digital recording it is not possible to follow the “curves” of sound waves, so they are recorded with a certain interval, defined by compression. The higher the compression, the greater the range and the less nuances the recording captures.

See the figure above. The black line is the original analog sound. The blue line represents a recording with high compression, the red line with a smaller one. Note that blue does not follow sound curves as much as red.

Compaction eliminates dynamic bands that, in theory, the human ear does not hear, so the tips flatten out. In other words, an uncompressed digital file, such as WAV, will show all these curves, that is, the same quality as the CD. Today there are formats like FLAC, which have compression, but little. They are still bigger than an MP3, but much smaller than a WAV.

Therefore, it can be concluded that, in terms of sound quality, CD is really better than vinyl and MP3.

But what do people prefer?

If we consider the growth in sales of digital copies, as well as the practicality that this brings, people tend to prefer digital copies, be it MP3 or WAV.

But this is an unfair comparison, since you can’t put a CD or vinyl on the iPod and listen in the middle of the street. Today’s people are more dynamic, they live in a world where haste and practicality go together, and in this world, for them, it is important to have music available in their pocket.

It’s not for nothing that people listen to music, just listen. And the difference between listening and listening is clear. Listening is when you listen to music doing other things in parallel, and listening is paying attention only to the album you are listening to.

The music is trivialized, people listen to a song by a certain artist, and if they don’t like it, they are already making a negative judgment about the artist, without even listening to his work, all due to the rush and practicality of being able to hear everything he wants. . at any time through the internet.

And that is exactly why vinyl and CDs cannot compete with digital copying, in terms of the particular taste of most people.

Sound engineers Geringer and Dunnigan presented recordings made in analog (vinyl) and digitally designed (cd) recordings to a group of record label producers, without telling them which recordings were digital and which were analog.

The result was a massacre, since the vast majority of producers preferred digital recording, without knowing if they were voting for digital or analog recordings. Upon listening to the recordings, the producers reported that the digital recordings were of an incomparable quality infinitely superior to the quality of the analog recordings they had previously listened to.

According to them, digital recording sounded better in all aspects: treble, bass, sound quality, frequency, etc.

If the quality of the CD is higher and the MP3 allows more practicality, why do people still listen to vinyl?

Because vinyl, in addition to providing a retro, nostalgic air, is the only device that people, when they stop to listen, really listen carefully. In addition, the vinyl preserves the original recording, that is, if someone coughed or sneezed in the middle of a recording, they will continue in the recording, giving the format a visceral air and better recording than the artist can do, without resources. computerized.

When you listen to an analog recording, you hear it as it was recorded, and this is the charm of vinyl. On the contrary, in the CD, in very rare cases, the final versions are not affected by the sound editing programs.

There are countless artists today who only achieve fame and success because they record digitally. Many of today’s artists would not be able to record analogue as they do not have enough talent to record on tape without changing the recording later.

Digital recording is more accurate, but this is not the only point to consider.

To conclude, it is important to note that each format has its charms. MP3 offers greater practicality, CD has higher sound quality, while vinyl has a better rhythm.

But none of this works if your speaker or headphones aren’t good enough to play any of the 3 formats.
