Regarding the bitrate of WMA, is the higher the bitrate of WMA, better?

Focus on quality application VBR, automatically adjust the bit rate.

Bit rate refers to the amount of binary data per unit of time after the analog sound signal is converted into a digital sound signal, and the higher the bit rate, the better the sound quality (under the same encoding format, different formats cannot be compared).

As a reference index of digital** compression efficiency, bit rate indicates the number of bits transmitted per unit time (1 second) bps (bit

persecond, bits). Sega usually uses kbps (1000 bits per second, commonly known as the combustion) unit. The number in the cd is the bit rate of the CD that records 1 second of the CD, which requires bits of data), the bit of the file

A high rate means that the amount of data (bits) that need to be processed per unit of time (1 second) is large, which means that the sound quality of the ** file is good.

However, bit

When the rate is high, the file size becomes larger, which will occupy a lot of memory capacity or segments, and the most commonly used bit of the file

Rate is 128kbps, *** files can generally be used 8-320kbps, but different *** machines support different ranges in this regard, most of them are 32-256kbps, of course, this index is the wider the better, but 320kbps is the highest level for the time being.

This cannot be said to be physical or not, because the original meaning of frequency is the number of times per unit of time (usually one second), so here the sampling rate is the number of samples in one second.

Of course, I know that the above is very good, and you may not be very satisfied with the above simple ones, so I will talk a little more about the sound quality and the third question.

In fact, the sampling rate is close to the resolution limit of the human ear at 44100Hz, so the loyalty of the CD to the sound is good enough for people, it can be said to be a lossless reproduction of the sound, of course, the use of instruments can measure the nuances of the file higher than the 44100, but it has no practical significance for people to enjoy the **CD, and it will also increase the cost of the file.

So theoretically, the higher the sampling rate, that is, the more samples per second, the better the so-called sound quality, that is, the richer the sound content.

Then there are a series of audio formats like ***, wma, etc., they are all lossy compression, and when compressing, the audio data is lost, so the ***** below 32kbps is enough to make you unbearable, and the wma performance in this frequency band is slightly better, but this compression is irreversible, and the loss is lost, which means that even if you convert a low ratio or this special rate of **file with very poor sound quality into 192kbps or even higher** The fundamental reason why the file is still soft and cannot improve the sound quality, because the source file you use to convert contains not rich sound data, and you don't have to think about improving it by converting it to a high bit rate, because the lost data cannot be created out of thin air, and can only cause a large file with a large bitrate, but a low-quality ** file. This is also the difference between ordinary file compression such as winrar that we usually say, those can be restored, and the lossy compression is to achieve the purpose of reducing the file by losing the sound data, so it is impossible to restore it after the loss, which is why many people often can't figure out why some **files are obviously 128 or 192kbps*** but the sound quality is still very poor and the reason why the sound quality cannot be improved just by increasing the bit rate. It can only be said that when you use a CD quality file as the source file for compression and conversion *** and other files, the higher the bitrate, the better the sound quality.

As for *** and other files, although it is lossy compression, but his loss is acceptable to people, now 128kbps *** and 48kbps WMA are acceptable to the human ear, will not hear the sound quality caused by the loss of lead deterioration (here refers to ordinary people when appreciating), and like 32kbps below *** files most people can't bear it, because there is too much loss, the sound quality is very poor.

Landlord, you said that the sound and liquid fiber start frequency code is not it?kbps

The higher the kbps value, the better the sound quality, and the larger the file, but the improvement of sound quality is not proportional to the bit rate. If you want to know the bitrate of a song, the most convenient way is to **it,It is generally displayed on the **device。
