These formats employ sophisticated algorithms that compress audio data while preserving every bit of information, resulting in files that are significantly smaller in size without any loss of quality.

Digitization of Analog Audio Sources

For analog audio sources, such as vinyl records or cassette tapes, a meticulous digitization process is necessary to convert them into digital formats. High-quality analog-to-digital converters (ADCs) are utilized to capture the analog audio signal with utmost precision and accuracy, ensuring a faithful representation of the original recording.

Metadata Organization and Tagging

Proper metadata organization and tagging play a crucial role in lossless audio archiving. Metadata includes information such as artist names, album titles, track numbers, and other relevant details. Organizing this information accurately not only helps in cataloging the audio collection but also facilitates easy retrieval and navigation.

Redundant Storage and Backup

Preserving audio fidelity necessitates redundancy in storage and backup. Multiple copies of the archived files should be maintained across different storage mediums, including external hard drives, network-attached storage (NAS) systems, and cloud storage services. Regular backups are essential to guard against any potential data loss or hardware failure.

Long-Term Preservation Strategies

Lossless audio archiving is not a one-time endeavor but an ongoing commitment. Implementing long-term preservation strategies ensures that the archived audio remains accessible and usable for years to come.

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.

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.

▲ 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.

Lossless Music

Lossless music is a kind of music file playback format, which is divided into two types: lossy compression and lossless compression.

type of sound
Commonly seen MP3, WMA, and OGG are called lossy compression. As the name implies, lossy compression reduces the audio sample rate and bitrate, and the output audio file will be smaller than the original file. . Another audio compression is called lossless compression, which can compress the volume of the audio file to a smaller size on the premise of saving 100% of all the data in the original file. Same size, same bitrate. Lossless compression formats include APE, FLAC, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC, La, OptimFROG, Shorten, and common and conventional lossless compression formats include APE, FLAC, TTA, TAK.
General WAV CD can capture this music format. However, due to the high volume and uncompressed original audio, it can usually be compressed and converted to FLAC or APE at a lower volume. Note: wav is still a lossless format, and the last two are lossless compression formats

BOW
APE is one of the popular digital music file formats. APE is a lossless audio compression technology, that is, after compressing the audio data file read from the audio CD in APE format, you can restore the file in APE format, and the restored audio file is the same as the original. compressed audio file. Exactly the same as before, nothing to lose. [one]
FLAC
FLAC is short for Free Lossless Audio Codec [2] , which can be interpreted as Chinese lossless audio compression coding. FLAC is a well-known free audio compression codec, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it does not destroy any original audio information, so it can restore the sound quality of music discs. It has been supported by many software and hardware audio products since 2012.
FLAC is similar to MP3, but it has lossless compression, which means that the audio is compressed in FLAC without losing any information. This compression is similar to Zip, but FLAC will give you a higher compression ratio, because FLAC is a compression method specially designed for the characteristics of audio, and you can use the player to play FLAC compressed files like you normally play MP3 files (many Car players and home audio devices already support FLAC, and you can find links to the manufacturers of these devices on the FLAC website).
FLAC is free and is supported by most operating systems, including Windows, “unix” (Linux, BSD, Solaris, OSX, IRIX), BeOS, OS/2, and Amiga. And FLAC provides a build system in autotools, MSVC, Watcom C and ProjectBuilder development tools.
WAV

The WAV format is a sound file format developed by Microsoft, also known as a wave sound file. It is the first digital audio format and is widely supported by the Windows platform and its applications. The WAV format supports many compression algorithms, supports a variety of audio bits, sample rates, and channels. It adopts a sampling frequency of 44.1 kHz and a quantization number of 16 bits. Therefore, the sound quality of WAV is almost the same as that of CD, but WAV format requires too much storage space, it is very inconvenient to communicate and broadcast.
WAV’s full name is Wave Audio Files, and WAV is derived from sampling analog waveforms of sound. Sampling the analog waveform of sound with different sampling rates can obtain a series of discrete sample points, convert the values ​​of these sample points into binary numbers with different quantization bits (8 bits or 16 bits), and then store them in the disc, this produces a WAV file of the sound, a wave file . Microsoft Sound System Sound Finder software can convert AIF , SND and VOD files to WAV format.
This format records the waveform of the sound, so as long as the sample rate sample rate

Digital Music

Surely changing our music from one side to the other, from an analog format to a digital one or even music already stored in digital format on a compact disc towards one for use on mobile devices, would result in a loss of sound quality that would exceed convenience and comfort.

This has been the main vision of people who care about sound quality, since the concept of digital music files was born. A reference generated by the common use of highly compressed lossy formats such as MP3.

wHowever, it is an opinion that simply “cannot take any more water.” Yes, popular formats like MP3 and AAC sacrifice some quality to keep file sizes small, but the emergence of lossless digital audio formats that are capable of preserving every piece of information from a CD recording means that a ripped file It may sound indistinguishable from the original.

You may still be wondering why you should spend precious time ripping up your CD collection. It’s all about convenience: a lossless digital music collection saves shelf space, is easy to move and to back up; for larger collections, it also makes locating individual songs and albums much easier and faster. You can also access a digital music library from multiple sources simultaneously, for example, from multiple network music players located in different rooms in your home.

Additionally, thanks to higher quality file acquisitions with popular streaming and download sites like B&W Society of Sound, higher quality music files can now be accessed as part of a subscription-based model without taking up space valuable on shelves – or even the attic – with physical means.

On the hardware side, storage devices like NAS and external hard drives offer huge amounts of space at ever lower prices. And with increasingly better and less expensive, widely available high-quality DACs, computers now offer excellent reproduction and can be easily connected to your existing hi-fi system, either wired or wireless.

When streaming or ripping discs, the file format option may seem complicated by too many options. This is what we think of the main formats that can be the salvation of true audio enthusiasts:

FLAC

Free Lossless Audio Codec is a popular choice for many audiophiles. Like MP3 and AAC, FLAC is compressed to keep file sizes relatively small, but unlike those formats, it is lossless and therefore – in theory – indistinguishable from the quality of a CD. In theory. Audio from CD converted to FLAC will typically shrink about 50 percent from its original size; a typical three-minute song on a CD will take up 30-40MB of space, while a ripped FLAC version of that song results in 15-20MB.

FLAC supports metadata (artist and song information can be embedded in the file and artwork can be referenced by the file) and will be played on a wide variety of software and hardware. Crucially for many, it is currently not compatible with Apple products like iTunes or the iPhone.

However, there are downsides to FLAC from an audiophile perspective and a lot of that comes during encoding and decompressing the file for playback. Because FLAC is unzipped on the fly, the sound quality is highly dependent on the software you are using to do that. Therefore, although it is theoretically lossless, there are still barriers to overcome when listening to the music contained in FLAC.

Apple Lossless

As you might guess from the name, Apple Lossless Audio Codec (or ALAC) was developed by Apple and works with company products like iTunes, iPod and iPhone (as well as supported by a number of other computers and players on software); If you are an avid user of the Apple team, it will be very attractive to you. However, like FLAC, this format is compressed, and files ripped from a CD are typically around 40-60 percent of their original size. Furthermore, ALAC suffers from the same decoding problems as FLAC.

AIFF

AIFF is a lossless format, but also without compression. While this means that it takes up as much space as the source file when ripping from a CD, it also avoids any compression issues, making it the ideal file for people who are concerned about sound quality.
