Lossless Audio

You might think of the word “lossless” as being used for audio formats that don’t use any kind of compression. However, even lossless audio formats use compression to reduce file sizes to reasonable levels.

Lossless formats use compression algorithms to save audio data so that the audio is exactly the same as the original source. This contrasts sharply with lossy audio formats like AAC, MP3, and WMA, which use algorithms that discard data to compress the audio. Audio files consist of sounds and silences. Lossless formats can compress silence to almost zero space while preserving all sound data, making them smaller than uncompressed files.

What lossless format is commonly used for digital music?
Popular lossless formats for storing music include:

FLAC
WAV
A THE C
lossless WMA
The effect of lossless formats on music quality
If you are downloading lossless music tracks from an HD music service, you would expect the sound quality to be really high. On the other hand, if you digitize a low-quality music box using a lossless audio format, the audio quality will not improve.

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.

Audio coding

Audio coding

There are many different ways to store digital audio.

The digitized sound is a set of signal amplitude values,
taken at regular intervals.

PULSE-CODE MODULATION
Let us set aside for recording one value of the signal amplitude in memory
computer N bits. Hence, with the help of one N-bit word one can describe
2
𝑁 different meanings. Let the amplitude of the digitized signal fluctuate in
within the range from 0 to 1 of some conventional units. Imagine this range
amplitude changes in the form of 2
Equal intervals. Now, for everyone’s record
separate amplitude value, it must be rounded to the nearest
quantization level (see quantization noise). This process is called
quantization in amplitude (level). Amplitude quantization – process
replacement of real values of the signal amplitude with values approximated to
some precision. Each of 2
𝑁 possible levels is called a level
quantization, and the distance between the two nearest quantization levels
called the quantization step. If the amplitude scale is divided into levels
linearly, then the quantization step is ∆ =
1
2𝑁
… This way of digitizing a signal –
sampling of the signal in time in conjunction with the homogeneous method
quantization – called linear pulse code modulation (PCM)
(Linear Pulse Code Modulation – LPCM) or just PCM (PCM).
To record sound on digital media or transmit via communication channels (see.
SPDIF interface) data in parallel code are encoded when
shift register, clocked by an auxiliary generator. At the exit
shift register, packets of coded pulses are formed in
sequential code.

Standard Audio CD (CD-DA) since the early 1980s
years of the 20th century, stores information in PCM format with a frequency
44.1 kHz sampling and 16-bit quantization.
There are varieties of PCM that use uneven
quantization step (Nonuniform PCM). Non-uniform (non-linear) method
quantization provides for dividing the amplitude scale into levels, according to
nonlinear (usually logarithmic) law. This way
quantization is called logarithmic quantization. Using
logarithmic amplitude scale, in the region of weak amplitude it turns out
a greater number of quantization levels than in the region of strong amplitude (in this case,
the total number of quantization levels remains the same as in the case of a uniform
quantization). The relative error is const.
An alternative A / D conversion method is
differential (difference) pulse-code modulation DPCM
(Differential PCM). In the case of DPCM, it is not the amplitude itself that is quantized,
and the difference between the current and the previous measured. In complete analogy with
PCM, difference PCM can be combined using both uniform and
and uneven quantization. For audio data, this type of modulation
reduces the required number of bits per count by about 25%.

Difference coding has many different options. For example, adaptive
DPCM (ADPCM, ADPCM) – a kind of DPCM with variable pitch
quantization. Changing the pitch allows you to reduce bandwidth requirements
transmission at a given signal-to-noise ratio.
A block of digitized audio information can be written to a file without
changes, that is, a sequence of amplitude values describing
audio waveform, i.e. uncompressed. For this it is usually used
.WAV format. Waveform Audio File Format (WAVE, WAV, from waveform) –
a container file format for storing a recording of a digitized audio stream,
RIFF subspecies. This container is typically used to store uncompressed
sound in pulse-code modulation. However, the container does not impose any
restrictions on the used encoding algorithm

Compressed audio with loss

Today we will analyze the audio files that have a loss of quality. Because digital audio files can be divided into two classes, those that are compressed suffer a loss of quality and those that have not had any loss.
The difference We will see later but for now we will be clear that each of the formats offers a different quality according to the algorithm that has been used to compress the music in order to save space on the hard disk.
Some definitely discard information which is normally sought to be inaudible information for the human ear or to be repetitive information, so even when information is discarded, quality is not lost.

Compressed digital sound files fall into two categories: those that have suffered lossy compression and those that have not.

Loss compression means that an algorithm that uses a smaller amount of information has been used. The resulting file differs from the original.

MP3 or MPEG1 Audio Layer 3

It is the most widespread and used compression format, in its various variants. The loss of information that involves the mp3 format passes (almost) unnoticed to the human ear.

An mp3 file can occupy up to 15 times less than its original while retaining high quality. This is why the standard for streaming is considered and is the most suitable type of file for use on the internet and for portable media.

WMA or Windows Media Audio

WMA is the Microsoft audio compression format. It was designed for playback with the Windows Media Player program.

WMA is the direct competitor in mp3 quality and compression with the difference that it adds author information. Its extension is * .wma.

Recently, Microsoft has developed a variant of the WMA format with compression, but without loss.

OGG Vorbis

Ogg Vorbis is a container format developed in open source, freely distributed and without a patent. This is the biggest difference with the rest of compressed audio files.

Files in this format have a high quality and can be played on almost any device. Its use is much less widespread than the previous ones, although, in some cases, it gives better results.

Its use is patent free. Therefore, many media players, such as the popular VLC, include Ogg codecs that, on the other hand, can be freely downloaded from the Xiph.org website. Its extension is * .ogg.
