What is lossless audio and high resolution audio?

If you only say the purest definition, the so-called "lossless" means uncompressed music. One professional explained this: Lossless audio is the unmodified output of the audio recording process and is the most accurate output reproduction of the existing recording process. This means that in theory it should record the sound perfectly. The sense of detail and space to bring the feelings and emotions that the music show needs to express.

However, the problem is that this theoretically non-destructive brings about excessive use of storage space, and many times this kind of occupancy is meaningless, because people often need to place as many audio files as possible in a wired space. Our common studio-quality lossless audio formats are AIFF and WAV. As we all know, their volume is not small, so the so-called "lossless compression" is born. In fact, we usually say "lossless" refers to the lossless compression of audio, it is cut to meet the narrower bandwidth transmission, and then be re-assembled, while retaining all the information. To some extent, it is very similar to the ZIP archives we are familiar with - files or multiple files Cheap Beats Headphones can be compressed smaller than the original, but it is recoverable. The compression mechanism for this type of file format is as follows: They use a compression algorithm to squeeze out the silent part of the music but do not compress the actual music content, or delete any data. This is not the same as MP3 files. Damage music format will remove the amount of information in the audio file. In this age when we are totally ignorant of storage space and internet speed, these complex processes seem Beats By Dre Sale to make no sense, but in the past, it was a very real problem to make music files as small as possible.

In addition to lossless audio, now we can often come up with another term: High Res Audio. Are these two terms referring to the same thing? It is not. High-resolution audio is much higher than MP3 in the amount of information, and is even much stronger than CD quality. Its design goal is to make the audio sound quality as close as possible to Beats Headphones Cheap the quality of the master disk, but its volume is not incredible. Undoubtedly, the larger the dynamic range is, the better, Cheap Beats Headphones" href="/">Cheap Beats Headphones because the greater the difference between the two extremes of sound loudness, it means that people can experience more emotional ups and downs while listening to some music, especially classical music. This requires the support of the playback device.

Then let's talk about the sampling rate. Analog audio is represented by a waveform, so when it is converted to a digital signal, a microphone samples it at regular intervals. The sampling frequency is the sampling rate. For example, 1 Hz means sampling once every second. High-resolution music is initially stored as a DSD file on a DVD-A or SACD disc, and only some devices that support such media can play it. Interestingly, Sony's UBP-X800 Blu-ray player is also capable of playing SACD. It is worth mentioning that considering the huge size of high-resolution audio and the now faster and faster Internet speed, this kind of music has now gradually turned to network downloads, not just mere disc carriers. In terms of streaming media services, some foreign platforms are now offering high-resolution listening, but it is a pity that streaming services such as Apple and Amazon have not provided high-resolution streaming. As for lossless music, its threshold is much lower. However, because this format requires the playback device to have the ability to decode files, not all electronic devices capable of playing audio support lossless formats. So many times, you can only see the lossless audio support on a dedicated player, or on a handful of smartphones that sell music.
