It minimizes CPU waste and helps the music to sound deep, bouncing well and relatively realistic. In general, this is said to know, but you do not need to care, what is of interest is the following 3 types.ģ, Variable bitrate (VBR): The purpose of VBR encoding is to create music files with the best bit-rate customization (The lighter the music, the lower the bit-rate and vice versa the stronger the music, the higher the bit-rate is, generally the most appropriate change.) The capacity is equivalent to CBR, so the ABR bit-rate customization is not really good.īecause of the bit-rate customization, the ABR’s capacity is a bit lighter than the CBR. This will limit the waste of the CPU, make the music sound more realistic, ABR was created to create the bit-rate customizable music just right. With soft music, the bit-rate will be low and the music will be strong, the bit-rate will be high. That takes up the music file.Ģ, Average bitrate (ABR): This ABR type is more advanced than CBR in that it has the ability to customize bit-rate, ie Different bass music scores, the number of Kbps will be changed accordingly. There is also an additional song when I was low, which song is not available, but the computer has to use the frame 128,000 bits /second as a result of listening to music without depth. logical 128000 bits /second, thus wasting CPU capacity. It is worth discussing that in sections where there is no music (usually the beginning and end of the song) or the sharp and jagged parts of the song, the computer still has to deal with it.
320 KBPS VS LOSSLESS 320 KBPS
Now I have a deep analysis of this bit-rate (you can skip), bit-rate in digital music has 3 types:ġ, Constant bitrate (CBR): music tracks are popular on online music websites that we call MP3 128 Kbps or 320 Kbps is Constant bitrate encoded (CBR), Constant bitrate is a fixed bit rate, ie, any 128 Kbps music file, the computer always handles 128,000 bits per second from beginning to end. Kbps is generally called Bit-rate, Bit-rate is the number of bits that the computer needs to process in a secondĬan you conclude that the higher the quality, the higher the Kbps number? I will answer at the end of this section. Kbps is generally called Bit-rate, Bit-rate is the number of bits that the computer needs to process in a second, a single application of 128 Kbps music requires the computer to be handling 128000 bits per second (because 1 Kbps = 1000 bits per second), similar to 320 Kbps music, the computer must handle a higher level of 320000 bits per second. We often listen to MP3 128 Kbps, 192 Kbps, 256 Kbps, 320 Kbps music … so Bit-rate or Kbps is what ? the presence of a certain sound frequency (may be more than 20Khz). In short, 1 second of the original sound will have a bitrate of 1411kbps … What is the nature of Lossless music?Īlthough the original audio bitrate is 1411kbps, it is not necessary to have enough bitrate to get the original sound because it is difficult to recognize the human ear according to human ear theory. 44100 sampling sessions * 2 left-right channels * 2bytes (16bit = 2bytes) * 60seconds = 10.584,000bytes = 10.1Mb Īs we know, 1 CD usually has a capacity of 750Mb, or save 74 minutes of music, so if you multiply the 10Mb number of every minute of music for 74 you will clearly see why it is like that.That means in 1 minute of music /sound we have: For digital audio, bit-depth will indicate the number of bits used to store audio signals.Īccording to the PCM standard, every second of audio is sampled with a sampling frequency of 44.1KHz (44100 times in 1 second) Each sample is expressed by 16 bits of data. + Bit-depth: Understand simply, bits are binary codes (0s and 1s) used to create data – or Music files that we download. + Sample rate: indicates the number of times the audio signal is measured and sampled in one second. PCM ( pulse-code modulation) temporarily translated as modulator, meaning that in analog we see 1 frequency of sine expressing sound, but in digital we cannot have sine waves that use different high-pitched “beats” in a continuous way to describe the most accurate sine wave shape) To understand and evaluate the quality of Lossless music you need to know the following issues: Previously, digital music was often recorded on 16-bit CDs at 44.1 kHz What is lossless music quality? Today, with the rapid development of audio technology, recordings with resolutions up to 24-bit, 32-bit with sample rate of 96kHz and even 192khz appear more and more popular. Lossless music relies on sound rules and compresses sound
