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.

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.

Lossless Audio

If an ordinary person suddenly “brings” what are considered experts in high-quality sound to the forum, they will find that 80 percent of audiophiles are talking about the bit rate problem. “If a true music lover can distinguish a recording with a good bitrate from a file ‘lossi’ or not”, the arguments on this subject with arguments for and against have not diminished in a long time. This proves that it is difficult or almost impossible to force people to abandon their beliefs, to step over their “ego”, even if the facts testify against their delusions. In this article, we will give you a little information about bit rate and how it relates to your practical experience of listening to music.

Lossless Audio

What is the bit rate?

If you love listening to music, you’ve probably heard the term “bitrate” before, so you probably have a general idea of what it means, but we’ll try to jog your memory and give you the “official” definition here. So the bitrate (from the bitrate in English) is in fact a stream: the information bit rate, that is, the amount of data processed over a period of time. In audio, it is generally measured in kilobits per second. For example, the music you listen to on iTunes is 256 kilobits per second.

The higher the bit rate of a track, the more space it will need on your computer. Hence, it has become common practice to compress audio CDs so that you can put more music on a hard drive (well, or in a “cloud” like Dropbox or whatever). This is where the legs of a long-standing dispute over the quality of music from lossy and lossless files “grow”.

What is the difference between lossy and lossless?

When we say “lossless”, we mean that we did not change the original file when rewriting, and it sounds like the track from the original CD. However, most of the time we save music with “losses”. A typical lossy album (MP3 or AAC) is probably about 100MB. The same album in a “lossless” format like FLAC or ALAC (also known as Apple Lossless) would take about 300MB. For this reason, “lossy” recording is common for fast downloads and to save more disk space.

The problem is that when you compress the file to save space, you are removing blocks of data. For example, when you take a PNG screenshot of a computer screen and save it in JPEG format, you get a “flaw” in certain parts of the image, making it almost the same, but with some loss of clarity and quality. . Consider the image below as an example: on the right, it was compressed in JPG format, and its quality deteriorated as a result (when looking at the car’s color, details, and background). The same is true of music files that are “compressed” to MP3, if the comparison is correct. Loss of quality visible to the human ear or eye is called compression artifacts.

Lossy files are understandably a tradeoff, but a very significant one when it comes to hard drive space, which can make a huge difference on a 32GB iPhone. But there are also different levels of loss: 128 kbps, for example, takes up very little space, but it will be of lower quality than a 320 kbps file, which, in turn, has a lower quality than a 1411 kbps file. (which is considered true without loss). However, there are many arguments that most people may not even hear the difference between the two bit rates.

Is the bit rate that important?

As file storage becomes easier and cheaper, high bit rate music becomes more popular. But is it always worth your time, effort, and disk space?

The answer to this question is not simple, and so far, audiophiles are breaking spears in battles, trying to solve an equation with two unknowns. The first part of the equation depends on the technical implementation. If you use expensive headphones or good quality speakers, you can listen to music in a wide range of sounds. And this is where the low bit rate becomes noticeable and you can determine that low quality MP3 files lack a certain level of detail, subtle background tracks may be inaudible, highs and lows will not be as dynamic, or it may just listen to other significant sound distortions. In these cases, the lossless format is justified.

But if you listen to your favorite music through a cheap and generally bad pair of headphones on your iPod, you won’t notice the difference between a 128 kb file and a 320 kb file, let alone a 320 kb file versus one without. losses. file at 1411 kbps.

Lossless audio formats

Lossless audio formats

Lossless

Although downloadable music files and music streaming have made music CDs less popular than before, they still exist and provide an excellent means of backing up your music collection. If you don’t back up your music, you could lose it if your hard drive fails. Even if all your music is on CDs, you should make copies of them because CDs can get scratched.

Lossless vs Lossy

You want perfect copies of all your originals in the event of a disaster, so stay away from lossy formats like MP3, which can affect the quality of your recordings. Use lossless audio formats when burning your digital music library to CD.

Lossless audio formats encode and compress audio losslessly, ensuring your music is perfectly preserved digitally.

FLAC (Free Lossless Audio Codec)
Free Lossless Audio Codec (FLAC) is the most popular lossless encoding format. It is increasingly compatible with hardware devices such as MP3 players, smartphones, tablets, and home entertainment systems. FLAC is a brainchild of the non-profit Xiph.Org foundation and is also open source. Music stored in this format is generally reduced by 30-50% of its original size with no loss of quality.

Common ways to rip audio CDs to FLAC include software media players like Winamp for Windows or special utilities like Max for Mac computers.

All major operating systems are supported by FLAC, including Windows 10, macOS High Sierra and above, Android 3.1 and above, iOS 11 and above, and most Linux distributions.

ALAC (Apple Lossless Audio Codec)
Apple originally developed its ALAC format as a proprietary project, but made it open source in 2011. Audio is encoded using a lossless algorithm that is stored in the MP4 container. By the way, ALAC files have the same .m4a extension as AAC, the naming convention can be confusing.

ALAC is not as popular as FLAC, but it may be the best option if iTunes is your preferred software media player and you are using Apple hardware such as an iPhone, iPod, or iPad.

There is no loss of quality when ripping ALAC music CDs, so this is a good option if you want to keep the original audio CDs. If at any time you need to switch from ALAC to another format, there will also be no loss of quality.

WMA Lossless (Windows Media Audio Lossless)
The WMA Lossless format, developed by Microsoft, is a proprietary format that can be used to rip original music CDs without losing sound quality. A typical audio CD is compressed between 206MB and 411MB, depending on several factors. The resulting file, which is created with confusion, has a WMA extension, which is identical to files in the standard (lossy) WMA format.

WMA Lossless is probably the least supported of the formats on this list, but it may still be the one you choose, especially if you use Windows Media Player and have a hardware device that supports it.

Mono audio
The Monkey audio format is not as compatible as competing lossless systems like FLAC and ALAC, but it does provide better compression on average, resulting in smaller file sizes. This is not an open source project, but it is free to use. Files encoded in Monkey audio format have the funny APE extension.

Methods used to copy CDs to APE files include downloading a Windows program from Monkey’s Audio’s official website or using standalone CD ripping software that generates data in this format.

While most software media players don’t have built-in support for playing files in the Monkey audio format, there is a good selection of plugins available for Windows Media Player, Foobar2000, Winamp, Media Player Classic, and more.

WAV (WAVeform audio format)
WAV format is not considered the ideal choice when choosing a digital audio system to store your audio CDs, but it is a lossless option. The downside to this approach is that files created in WAV format are larger than other lossless formats, since no compression is used.

If storage space is not an issue, then the WAV format has a number of distinct advantages: it is widely compatible with both hardware and software. Converting to other formats requires significantly less CPU processing time because WAV files are already unzipped and don’t need to be unzipped before converting. You can also directly manipulate WAV files with your audio editing software without having to wait for decompression and recompression cycles to update your changes.

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.
