Highest quality music format. – part 6
Audio CD file: FLAC has a CUESHEET metadata block in which the audio CD markup table is stored.
For example, you can burn an audio CD to a single file and then import its markup table when encoding, so that the resulting file has the same layout as the disc. If the original audio CD is damaged, you can restore the partition table to write an exact copy of the disc.
Error resistance: Due to the division into frames, errors in the sequence are located at the level of the frame where the error occurred (usually a few hundredths of a second). In some codecs, a single error can cause the entire rest of the stream to be lost.
But this is all prose. The trick is this. As you know, the original CDs are divided into only 2 channels, that is, the usual STEREO. The Flac has the multi-channel playback capability, up to 8 channels BUT if you remove a copy of the Flac from the original compact, the multi-channel capability remains unused and as a result we have the same 2 channels and stereo. The size of flac differs from mp3 by about 6 times.
Monkey Audio (* .ape)
The * .ape format in which Monkey’s Audio encodes, the most popular among lossless codecs. Even those who don’t know what “lossless compression” have heard of it. The reason for its popularity is the free and very high quality codec. stream compression, which even exceeds traditional WinRAR archiver compression at maximum settings. Support for the format is implemented in various players (eg Foobar2000), a plugin for Winamp comes with Monkey’s own audio, and for all remaining players you can install one of the DirectShow filters (eg Radlight). The only downside to this format is the presence of the Windows platform only. The Playback plugin supports all popular features like gapless and replaygain and ID3 tags like MP3. When encoding the stream, there are five different compression rates available, from Fast to Insane. The latter option provides an unprecedented compression rate that no one else can match. A lossless codec, but the processor load when playing the resulting file is also quite large. Having installed the Monkey Audio Distribution Kit, you will be able to encode a few other formats as well, including OGG, WavPack, Shorten, Lame. All of them are also compatible with the graphical shell.
AAC (* .aac, * .mp4, * .m4a)
The main advantage of AAC is its support for multichannel audio, thanks to which it got a “permanent job” in DVD video production. At the moment, there are already quite a few AAC codecs, among which the most famous is AAC LC, used in Apple QuickTime technology. The use of Nero AAC in the Nero Burning Rom package is also common. The number of hardware players that support AAC is growing, the most popular now being the Apple iPod, which works with * .m4a files that are created with iTunes or downloaded from the Apple online store. In a sense, the AAC format can be called very viable, as it is already used in the industry and obviously it will not be allowed to “wear out” so easily. Hence the solid confidence of ordinary users, who may well rely on it, choosing a replacement for the old MP3.
DVD-Audio is a digital DVD format specially created for high-quality audio playback. A DVD-Audio disc allows you to record soundtracks with a different number of audio channels (from mono to 5.1).
Multi-channel audio support is a major advantage DVD-Audio has over previous formats. The presence of 5 loudspeakers allows the positioning of the sounds in a three-dimensional space, which offers two new possibilities: the precise transmission of the acoustics of the room and the creation of new sound images intertwining special effects with the musical content itself. The human hearing aid distinguishes the direction of sounds not only from left to right, but also from back to front (and, to a lesser extent, from top to bottom), so two channels of audio are not enough to simulate volume. .
The sound of the record can be quantized to 16, 20 or 24 bits, as well as sample rates of 44.1, 48, 88.2, 96, 176.4 or 192 kHz. (A maximum of two channels of audio can be recorded at a sampling frequency of 176.4 or 192 kHz.)
There are two versions of the DVD-Audio format: simply DVD-Audio only for audio content and DVD-AudioV for audio with additional information.
SACD – Acronym for Super Audio Compact Disc – an optical disc format for storing music. Double Layer or Hybrid – readable on both regular CD players and SACD players.
