lossless sound quality

The principle of these audio compression methods is to keep as much as possible the parts that are easy to hear for the human ear.

In the main constant bit rate (CBR) mode, audible data in the audio is removed and it is easier for the human ear to hear. The more information that is retained for the part, the less information that is retained for the less audible part. As sound complexity increases, the degree of sound quality degradation becomes more apparent. For example, when listening to pure human music voice performances and performances combined with background music, pure The degree of degradation of the compressed music of the human voice is less obvious than that of the original file.

As for the lossless sound quality provided by today’s streaming platform, there are many formats, but strictly speaking, these formats, including flac and ALAC, belong to lossless compression (non-destructive data compression) rather than quality. lossless sound in a narrow sense, but due to its performance it is almost the same as WAVE, but the file is small, the decoding speed is fast, and it can be used in streaming services, so it is also a representative format of lossless sound quality that has entered the era without CD support, and it is also the current music streaming service.

Also, MQA like Tidal is a more controversial format, because although MQA is lossless audio compression in a broad sense, it focuses on driving high-quality music files that are above CD quality at a size similar to those of CD quality flac files. , but it can also be restored to the original high-quality audio format, but the controversial point is whether the higher compression ratio can maintain the same real auditory sense as the original high-quality audio has always been controversial. At the same time, MQA requires a specific device to perform hardware decoding. Yes, many devices can only decode MQA through software.

▲Currently called Hi-Res Audio generally refers to sound quality higher than that of a CD, but to be certified, the device must support the processing capability of the 24-bit 96kHz format.

However, since MP3 and AAC are previously planned destructive music compression formats, their purpose is to compress CD-level sound quality into smaller files, so most encoding specifications are presented in one presentation. CD-level 16-bit 44.1 kHz or 16-bit 48 kHz; but MQA is a format with a small file size that locks in high sound quality requirements. Basically, the MQA format will be music equivalent to 24-bit PCM or higher.

Although lossless sound quality and high-quality streaming services have appeared on the market for a while

Like Apple isn’t the first to make true wireless earbuds, but it has ridden the wave of the market, with Apple’s launch of so-called hi-fi. compressed sound quality in Apple Music. In fact, after the lossless compression commonly known in the audio industry, lossless sound quality and high sound quality have instantly become a hot topic for many people to discuss, but whether the benefits of quality Lossless sound systems are really Obviously, the author will devote some space from theoretical concepts to practical levels. The difference is a simple overview, but the following arguments focus on easy understanding, so some of the descriptions are not entirely accurate.

What is lossless sound quality? What is the sound quality of the music we usually listen to?

▲ Both AAC and MP3 are destructive compression, while FLAC and ALAC are lossless compression

Before we get into the details, let’s talk about what is called lossless sound quality; From the author’s concept and cognition, the so-called lossless sound quality is a relative word rather than an absolute word. The main source is the relative word born due to the appearance of the MP3 music compression format; after the music industry went digital, digital music files were generally recorded via PCM encoding, and WAVE files were generally used on CDs. The time and space situation that MP3 was born into was because hard drive capacity was generally small at the time. To store a large amount of music data in storage space, you probably need to compress the files.

The reason why MP3 cannot be called a lossless format is because it essentially compresses the original WAVE in a way that limits the bitrate by combining concepts like the psychology of sound. The bitrate compression mode, compared to the bitrate of the original WAVE file, compresses at least in a range of 1:4 to 12:1. The higher the bitrate, the greater the amount of retained information. For example, AAC format also adopts similar audio psychology for compression, but the efficiency is better than MP3. Therefore, most of the lossless sound quality of most streaming platforms currently uses AAC as the mainstream.

What is the difference between lossless sound quality and normal sound quality?

When downloading music, we often see these options: lossless sound quality and normal sound quality, lossless sound quality requires members to download, otherwise only normal sound quality can be downloaded.

Since it is a fee, the lossless sound quality must be higher than the normal sound quality, so what are the differences between them?

Commonly seen MP3, WMA, OGG are called lossy compression. As the name suggests, lossy compression is to reduce the audio sample rate and bit rate, and the output audio file will be smaller than the original file, which is normal sound quality. we often see.

Common MP3, WMA and other formats occupy about 1M-5M of space for single-handed songs, while for music in lossless formats such as ape and flac, the space occupied by a single song can generally reach tens of megabytes, or even more than 100M.

Bit rate (Kbps) refers to the transmission rate of digital signals, that is, how many thousands of bits of information are transmitted per second (K means thousands of bits, Kb means how many thousands of bits). For music, theoretically this The higher the value, the better the sound quality. Ordinary music, such as WMA, is generally 128kbps music, MP3 is mostly 128 or 192 or 320kbps/, while the bit rate of lossless music generally reaches 800-900kbps, and traditional CD even reaches 1411 Kbps. Using lossless compression, the sound quality is the most perfect.

The feature of lossless music is that regardless of whether there is sound between the beats, its data always flows smoothly, so the fast magnetic vibration in your headphones is stable, and the sound is natural and real; while lossy formats such as MP3 are due to the loss of people The ear can not hear part of the data, so the magnetic block in the earphone vibrates unnaturally, causing it to vibrate when there is sound, and do not vibrate when there is no sound, so the magnet block vibrates excessively and unstable, which will produce burr noise. If professional equipment is used, it is easy to hear right and wrong.

Of course, whether you can hear the difference depends on the person, and there are differences in everyone’s speech recognition ability. Some professionals and people with sensitive hearing will find the difference, but for most common listeners, in fact, there is no difference between normal MP3 and FLAC lossless sound quality, and the effect is similar.
