Audio encoding and processing. Audio encoding
There are three main types of audio digits:
format – no compression;
format (lossy) – lossy compression;
format (lossless): lossless compression.
Lossy compression: technology in which there is a significant reduction of the encoded file compared to the original, due to the removal of information that is not perceived by the human ear.
The downside of this technology is the fact that the compressed file will never be identical to the original.
Lossless – Lossless compressed audio formats, including:
FLAC (Free Lossless Audio Codec)
APE (mono audio)
WV (WavPack)
These formats are capable of converting CD to digital format while maintaining quality. As an example, you can take a CD, convert it to WAV, then WAV to FLAC, then go back from FLAC to WAV, and then burn it to a blank CD and you have an absolutely identical copy of your source.
What format does the music sound with the best quality?
The most popular is the lossless FLAC format, and one of the most widely used CD to FLAC conversion programs is EAC (Exact Audio Copy).
Of all the parameters of digital audio, it is necessary to pay attention first of all to the following indicators:
sampling rate (precision of digitizing an analog signal in time),
bit rate (the amount of information contained in the file in terms of one second).
The sample rate is the frequency at which digital audio is processed. The most common sample rate for quality audio formats is 44.1 kHz.
It is generally accepted that a high bit rate guarantees the best quality; this is true, but only if the source file is of good quality. A high-quality MP3 should have a bit rate of 320 kbps, but a high-quality FLAC format generally has a bit rate of 900 kbps or more.
What is the best quality music format?
In addition to the audio formats themselves, for high-quality music sound, high-quality reproduction equipment is also needed: speakers, amplifiers, headphones. In other words, if you use cheap desktop speakers and headphones, you won’t be able to fully enjoy high-quality sound and unleash the full potential of lossless formats.
Without going into technical details, the following formats can be recommended:
For listening at home, I recommend the best FLAC format in my opinion. For an audio player, the MP3 format with a bit rate of at least 320 kbps is a good solution. Personally, I only use the FLAC format on all devices, since the volume of the microSD cards allows you to store a sufficient amount of data on the player.
As for the equipment for high-quality music playback, I advise you to pay attention to the following brands:
If inexpensive acoustics do not suit you and you are a fan of high-quality sound equipment (Hi-Fi or Hi-End), then everything is in your hands and you are limited only by your budget, I will not give recommendations.
