I can t hear the difference between lossless and lossy

To hear the difference, there are the following conditions.

1. There must be true lossless audio. Some "lossless" audio is made with lossy audio, but lossless formats are lossy sound quality. In addition, the CD disc itself may be pirated, or genuine but there is a problem with the master band, resulting in **CD itself The sound quality is not high, so it is lossless and lossless to hear the difference.

2. There should be good equipment and good headphones, audio and other equipment. Some sound cards have poor audio output due to their own design parameters and working environment problems. In addition, don't expect hundreds of speakers or dozens of yuan headphones to have a good effect, no matter how good the lossless equipment is, it doesn't sound much different from ***.

3. Have a good ear for listening. Some people have good ears, just listen to a short piece of the violin to hear that the piano is produced by **, and even can tell who the luthier is; And some people can't even hear the difference between the sound of the violin and the erhu.

For the average human ear, the difference between the so-called lossless format and the *** with a higher sampling rate is not very obvious. Of course, it also has to do with the ** equipment used. Our common lossless compression** file format.

1. Lossless and ordinary** compression encoding methods are different.

When people record the singer's singing voice as the original file of the digital **, then the **file at this time is very large, so it is not convenient to store, so people compress it, and almost all the popular digital ** formats are compressed, just like including etc.

It's just that their respective compression encoding methods are different, lossless (is lossless compression, and ordinary ** and those small formats such as *** are lossy compression.

2. The sound quality is different.

The feature of lossless ** is that no matter whether there is sound between rhythms, its data always flows smoothly, so that the magnetic fast vibration in your headphones is stable, and the sound emitted is natural and real;

And *** and other lossy formats due to the discarding of the human ear can not hear the part of the data, so the magnetic block in the earphone vibrates unnaturally, resulting in vibration when there is sound, and does not vibrate when there is no sound, so that the magnetic block vibrates excessively unstable, and will produce a burr noise, which can be heard with professional equipment.

3. The size of the file varies greatly, and the lossless file is larger than the ordinary** file.

The common ***, wma, and ogg are called lossy compression, and lossy compression, as the name suggests, is to reduce the audio sampling frequency and bitrate, and the output audio file will be smaller than the original file. Another type of audio compression, known as lossless compression, can compress the volume of the audio file to a smaller size under the premise of saving 100% of all the data of the original file, and restore the compressed audio file to achieve the same size and the same bitrate as the source file.

o( o No copy loss**The sound effect is better, it is exactly the same as on the CD, but the general home equipment is not audible, there is no difference, the general lossless** are 320kpbs, usually we listen to 128 or 192, the lossless ** occupies a larger area than the general**, we can't hear the difference on weekdays, so there is no need.

I'll be honest with you, it's not too big.

Du Tong, there are no hundreds

DAO professional.

The inner ear can't tell the difference.

A lossless song. The bitrate of APE and FLAC is generally 800K, that is, a song is about 30M, except for the hard disk, I don't see much difference, so there is no need 192K's is completely sufficient!

What's more, a lot of APEs were transferred from the low-quality version by someone else.

Whether the sound quality is good or not depends on the sound source. As long as the bitrate is not less than 150, it is OK!

For headphones that cost at least 500 yuan, you can feel it.

What kind of front-end do you use?

There are three differences: 1. The size is different. A song with standard sound quality is about 2-4MB. A song with super high sound quality is about 5-10MB. Lossless sound quality, a song is about 100m.

2. The sound quality is different. The standard sound quality doesn't sound too rough. Songs with super high sound quality sound feel more detailed. (e.g. the sound of the accompanying instrument) without sacrificing sound quality of the song sounds very clear.

3. Different classifications. Standard sound quality, ultra-high sound quality is lossy sound quality. And lossless sound quality naturally belongs to lossless sound quality.

Lossless**contains all**information,It is a necessary condition for high fidelity,Lossy**In order to reduce**volume,Remove some unimportant information,It is not obvious on ordinary audio,There is a difference in professional equipment。

There could be many reasons for this:

The computer's sound card doesn't work.

Speakers Headphones don't.

Your personal problems.

Cherish it, this is the happiness of fungus

When people record the singer's singing voice into the original file of the digital **, then the **file at this time is very large, so it is not convenient to store, so people compress it, almost all the popular digital ** formats are compressed, just like including etc., but their respective compression encoding methods are different, we often say lossless (that is lossless compression, and the previous *** and other small formats are lossy compression.

Lossless compression is like flattening a loaf of bread, making it smaller in size, but the same in mass. Most of the sounds we record are actually too high or too low for us to hear (some animals such as bats, dogs, etc. can hear some of them). So we delete this part of the inaudible sound data, and the part of the data that can be heard by the human ear will become very small and easy to store, this compression method is called lossy compression (such as ***).

So what's the difference between lossless and lossy sound quality?

Have you ever had such an experience of the same song, we will sing the next *** and a flac, and then put on headphones and listen to it, but we can't find the difference in sound quality anyway! But if you listen to *** all day and listen to it all day without loss, it will be a different feeling! Listening all day *** ears are easy to get tired, and listening without damage is not much of a problem (as long as you don't fall asleep, hehe)!

What causes this? This is what I call the difference between lossless and lossy sound quality today! We know that there is a rhythm, and there is a difference between rhythm and rhythm, such as between treble and bass, no matter how rapid or slow the song is, it will always have an excessive, lossless** feature is that no matter whether there is sound between the rhythm (whether we can hear it or not), its data always flows smoothly, so that the magnetic fast vibration in your headphones is stable, and the sound produced is natural and real; And *** and other lossy formats because of the discarding of the human ear can not hear part of the data, so the magnetic block in your headphones vibrates unnaturally, resulting in vibration when there is sound, and does not vibrate when there is no sound, so that the magnetic block vibrates excessively unstable, and will produce a burr noise, maybe you can't hear it, but the ears will be unhappy when listening to songs for a long time (of course, some good headphones can also avoid this glitch sound, but most of the engine oil can't afford it).

The difference in bit rate, the general ***** reaches 320kbps, the sound quality is very good, lossless** generally reaches 800-900kbps, some exceed 1mkbps, the main format is ape and flac, its practical computer listens to the average person can not hear, there is no meaning, only the fever ** useful professional equipment can listen to the good or bad So use the computer to listen to the ordinary on the line!! Hope to adopt.

Professionals can tell that it is generally not audible without ** foundation, and in general it is a problem of sound quality.

Lossless**There is no noise in some songs, and there may be noise in the ordinary**.

Some can't be heard, but some can be heard. But if you amplify the sound, you can hear it.

When the volume is increased, the sound quality will not be too distorted.
