<\/p>\nMusic files can be the product of the perfect extraction of the music contained in CDs, called bit by bit. With this phrase we immediately clear the field of feeding unjustified prejudices towards the archives. The files are not of the same quality as CDs when using lossy formats: MP3, AAC, M4A. Besides these, there are formats that do not use any type of compression: WAV and AIF, which are the exact copy of the songs stored on CDs or even the original master recording format used to create CDs. Or there are formats that even using compression are “lossless”, called lossless: the most widespread of them is the FLAC format, not surprisingly adopted as a standard in the distribution of content in CD quality or higher. The FLAC format uses a type of compression that does not remove the original data. When unzipped, FLAC files have exactly the same bits that were present before compression.<\/p>\n
<\/p>\n
Before there are misunderstandings about the relationship between lossy and lossless files, we specified that if you have an MP3 file and convert it to FLAC, the data removed from MP3 transformation will not magically appear again. No conversion can regenerate the lost data into a lossy file. You can convert FLAC files to WAV or AIF because the compression used was lossless.<\/p>\n

The FLAC format also has advantages over WAV and AIF, the applied compression reduces its size and saves storage space and data bandwidth in reception \/ transmission when transmitting over the network. Besides this function, FLAC has another advantage over WAV, the information describing the tracks and the cover image can be inserted into the files. The information inserted in the files is called TAGs, the FLAC format provides for the insertion of this information that software applications and APPs read to recognize the content of the audio tracks. This simplifies the management of music collections, which without TAGs would present indistinguishable lists of audio files. Unfortunately, the standard WAV format does not allow the inclusion of TAGS in files.<\/p>\n
Let’s continue the discussion on the playback chain of a portable Hi-Fi system. The technical quality of the content to be reproduced affects the final quality of the reproduction.<\/p>\n
After adopting quality headphones, it would be wise to switch to lossless audio formats, to at least benefit from the original quality found on CDs.<\/p>\n
Lossless music<\/p>\n
Most of the sites that sell music online offer it in lossy formats, so the problem is how to get music without loss. Anyone with a CD can start by ripping them. Ripping is the term used to describe the transformation of the tracks contained in a CD into files. Anyone who wants to delve into the subject can read the writings dedicated to Ripping and the creation and management of music collections: What software for ripping and Creation and management of music files luquida.<\/p>\n
In addition to CD ripping, there are websites that sell lossless music online in CD quality and Master Quality (Hi-Res), the latter is superior to CD and in many cases coincides with the original recording made in the Recording Studio.<\/p>\n
High Resolution Music (HRA) has higher technical specifications than expected for CDs. Resolution ranges from 16 bit to 20\/24 bit and sampling from 44.1 kHz to 48 \/ 88.2 \/ 96 \/ 176.4 \/ 192 kHz. For a description of the processes and characteristics of digitization, read the following text: The digitization of sound. With respect to these specifications we believe that the determining factor is the 24-bit resolution combined with sampling performed at least at 48 kHz.<\/p>\n
Speaking of MP3 files, we usually refer to the bit rate, which with this format does not exceed 320 Kbps. The bit rate indicates the bits per second transmitted in a music stream. It is quite evident that a music stream consisting of more bits will contain more audio data. To orient yourself between these parameters, it is good to bear in mind that an uncompressed CD quality audio stream (16 bit 44.1 kHz) is 1,411 Kbps, converted to FLAC the stream will decrease between 30 and 50% of the format’s bit rate. uncompressed. Therefore, the CD quality stream generated by a FLAC will vary approximately between 705 and 988 Kbps. Obviously for high resolution formats the data stream will be proportionally higher depending on the specifications offered by the individual files.<\/p>\n
The technical quality of the content to be reproduced as well as the reproduction devices are essential complements to obtain the best sound result.<\/p>\n","protected":false},"excerpt":{"rendered":"
