Lossless vs lossy
lossless maudio quality mp3 flac
The evolution of devices or equipment that reproduce audio, as well as that of headphones or speakers, have made people wonder more and more if the time has come to resort to lossless music, for example FLAC.
Before, a few years ago, it was a bit absurd to talk about lossless formats when we used equipment that had low audio capabilities on a daily basis.
But now, as many phones and computers contain DACS that have high capacity, one can already think about it without it being nonsense.
And it is not so obvious nor is the question trivial.
For one, there is a lot of bloof in this area. Where many people repeat slogans that take for granted the automatic superiority of lossless. On the other hand, we are entering a stage where true high audio quality is being achieved, including the audio that accompanies videos.
Mp4Gain, it should be noted, is perfectly compatible with this world of high quality audio and video (including video audio).
And Mp4Gain can not only normalize the volume of audio and videos perfectly, but can easily convert to lossless formats with great ease and great results.
It may be worthwhile to try and convert some files to formats such as FLAC and, incidentally, normalizing the volume and listening to them on our computer or device.
Undoubtedly sooner rather than later we will find ourselves fully in the world of high fidelity audio, if not you are already there. It is quite possible that your phone or your computer can already handle this high level of audio perfectly.

Difference between lossless compression and lossy compression?
Lossless compression is the first step without the above. Therefore, lossless compression can restore data equivalent to what it was before compression, while lossy compression cannot. The scale of “loss” in lossy compression is controllable and algorithms are used to extract information before removing it.

What makes an audio format lossless?
The best audio formats for your music library
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.

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.

Is it possible to convert lossy songs to lossless?
Going from lossy to lossless is never a good idea. This is because a song that has been compressed using a lossy format always does. If you convert it to a lossless format, all you do is waste storage space on your hard drive or mobile device. There is no way to improve the quality of lossy songs using this method.
Advantages of using lossless audio formats for your music library
Using a lossy format like MP3 is still the most common method people use to store their music collection. However, there are clear advantages when it comes to building a lossless music library.
Perfect Music CD Backup: Lossless Copy to Audio Files gives you an exact bit-level copy of the original music CD. This means that no matter what audio format comes out in the future, you’ll know you have a perfect copy of the original.
Recover from lost or damaged: After playing music in lossless format, you can recover a damaged original CD or any CD that has been lost to a blank CD.
Convert to any format: Since your music is in a lossless format, you can convert it to any format and achieve the highest quality the format supports.
Disadvantages of Storing Music in a Lossless Format
Incompatible – Unlike formats like MP3, hardware devices like smartphones and tablets do not support lossless formats.
Requires more storage space: Lossless audio files generally require more storage space than lossy encoded files.
What equipment do you need to enjoy lossless audio? Part 2
digital to analog converter
Sound is an analog signal. Vibrations from objects generate it and air molecules spread it, so we can hear it. For this reason, there is no sound in space because there is no air to transmit it.
This is why you need a dedicated digital-to-analog converter (DAC). These devices are designed to convert digital signals to analog signals. While computers, smartphones, and other devices have built-in DACs, they’re often not optimized for music.
Also, analog signals are susceptible to interference. The DAC inside the device may receive interference from other components, such as the computer’s power supply or the smartphone’s 5G antenna. If you find that your audio output is too low, you definitely need a DAC with an integrated amplifier.
2.4 GHz wireless or wired speakers, headphones or earphones
If you want to take full advantage of lossless files, you need earphones or headphones capable of outputting high-fidelity audio. Unfortunately, even the best Bluetooth headphones cannot transmit uncompressed sound data.
While recent Bluetooth technology can transmit high-resolution sound, it’s still not enough for lossless audio. If you want to listen wirelessly, you must use a 2.4 GHz USB wireless connection. This is the only wireless audio technology that offers lossless transmission. Some alternatives, like Sony’s LDAC or Qualcomm’s aptX HD, come close, but it’s not “true lossless” audio.
However, if you need high-quality audio, it’s best to stick with the wired audio output. Since wired headphones are physically connected to your DAC, they receive analog audio signals directly. So your music will no longer go through conversion, compression or any other process. This ensures that you can enjoy the audio output of the DAC as it is.
High fidelity audio output
Of course, the most critical part of any listening experience is the speakers or headphones. Whether you’re playing lossy or lossless audio, if your audio equipment isn’t up to the task, you won’t be able to enjoy your music.
You need to look at various audio specifications, such as driver type, impedance, etc., to understand what makes a good speaker or headphone. Still, having impressive specs on paper doesn’t equate to great sound quality.
The only way to find the best speakers or headphones for your ears is to try them out in real life. You can also trust product reviews and comparisons from trusted sites; this way you can see other options that you haven’t considered before.
But if you have the budget, you can go ahead and invest in Bang & Olufsen. and Harman International. These speaker and headphone brands cost more than their competitors. But it is almost guaranteed that you will get the best audio quality from them.
The products of such companies are made of high-quality materials. They also have R&D facilities to ensure their speakers, headphones and earphones deliver the best sound quality possible.
What equipment do you need to enjoy lossless audio?
If you like high-fidelity audio, you’ve probably heard of lossless audio. You have probably read some articles about it and now you want to enjoy it for yourself.
But what hardware do you need to access high-quality audio? Can you use an existing device or do you need specialized drivers? Here’s a quick introduction to the hardware you need to enjoy lossless audio.
What is lossless audio?
Lossless recordings take up a lot of space: about 30 MB per song. But in the past, storage space was at a premium. The internet connection is also slow and unreliable. Therefore, the first iPod’s 5GB of storage could only hold about 166 lossless audio files.
That is why lossy file formats like MP3 were introduced. About 3-5 MB per song, you can store more than a thousand songs on the first generation Apple iPod. But as the Internet has gotten faster and storage space has become more affordable, the need for highly compressed audio has diminished.
File compression reduces file size by sacrificing quality. So if you’re listening to music with lossless audio, that means you’re listening to what was recorded. Lossless audio uses a compression format that does not cause any data loss or does not compress the audio at all.

Lossless device for lossless audio
Now that you have a lossless audio file, it’s no good if you plan to play it on an audio device that compresses the data. After all, if data is lost between the computer and the speakers, you won’t be able to enjoy the best audio quality.
So this is what you need to get the best audio out of your lossless music files.
Lossless Audio vs. Hi-Res Audio: What’s the Difference? Part 4
Difference Between Lossless and Hi-Res Audio
As we explained earlier, lossless audio is an audio sample without any downstream compression on top of it. Such samples are in raw form.
So lossless audio does not mean higher quality audio. Any audio, hi-res or not, can be lossless.
Hi-Res Audio, on the other hand, is better quality audio with higher bit depth and high sample rate. High-Resolution Audio can be lossless or lossy.
Hi-Res Audio Format
With the rise of Hi-Res Audio, streaming services have started to introduce some proprietary audio formats. Some of the more popular formats include FLAC, AIFF, WAV, and ALAC. All of these formats support High-Resolution Audio with lossy or lossless compression.
For example, Apple uses ALAC for high resolution streaming on Apple Music. ALAC is a lossless format, which means that its compression does not degrade sound quality. It is also very space efficient. Compared to WAV without applying compression, ALAC takes up half the storage space.
Related: The Most Common Audio Formats: Which One Should You Use?
Like Apple, Tidal uses its own audio format, MQA. MQA has lossless compression and offers almost the same sound quality and storage space advantages as ALAC.
Audio without loss against high resolution audio: What is the difference? Part 3
What is the sampling frequency and the depth of bits?
Computers are digital machines that handle 1 and 0. Therefore, any information that a computer needs to store, including audio, should be stored as a chain of some and zeros.
On the other hand, the sound is not digital. It is analog and continuous nature. Then, if we want to store the sound in the computer storage unit, we must convert it to 1 and 0.
There are many ways to make this conversion. The simplest is the pulse code modulation (PCM).
The representation of the pulse code modulation is shown below.
In PCM, we take analog audio, reproduce it and sample it at a predetermined speed in the form of some and zeros. This data is then stored in audio format.
To better understand the process, imagine a photo of you playing baseball with the children. If you take 30 photos per second in an hour, you will have enough data to make an hour of video clips of 30 fps.
The same happens when you show an audio signal. It is taking a pictorial snapshot of the audio signal at an established speed. Codify all those snapshots and you will have an audio file.
To play an audio file, your computer only needs to play the snapshot at the same speed that was captured. This frequency is called sampling frequency.
We measure the sampling frequency in KHz. The standard sampling frequency for audio CDs is 44.1 kHz.
Now, since any audio consists of multiple sounds of different frequencies, we need to store multiple 1 or 0 to store all the necessary information. Therefore, we must strive to obtain the largest possible sample size, because the greater the sample, the better the sound quality will be.
The sample size, which is the number of bits in each sample, is called depth of bits. The depth of standard bits on the audio CDs is 16 bits.
High resolution audio
In spite of all the uproar over high resolution audio music transmission services, surprisingly there is no standard definition. There is no consensus on what is high resolution audio.
That said, the consensus is that the audio samples with high sampling and high-depth bits are called high resolution.
As you can see, the previous definitions change constantly. For example, when the 8-bit audio is the standard, 16 bits / 44.1 kHz is high resolution. Nowadays, when 16 bits / 44.1 kHz is the standard, 24 bits / 96 kHz is located in the field of high resolution.
In theory, high resolution audio sounds clearer and better. It has a greater dynamic range, better separation of instruments and low noise level.
