Main audio formats without loss of quality.
WAVE (.wav) – This is the most common uncompressed audio file format. When you rip audio from a music CD on your computer, this will be the format you get. It takes up a lot of space (1411 KB of information per second on 4400 Hz / 16 bits of stereo music), but reproduces the sounds in a quiet way. In terms of quality and amount of information, it resembles the AIFF (.aif) format, which is mainly part of the Mac world. Suitable for audio files and those that record music.
FLAC (.flac) – Free Lossless Audio Codec: It is an open source codec that is often used to store music CDs on the computer without loss of quality. While .wav offers uncompressed audio, .flacs are called “lossless c compressed”. However, compression is minimal and the vast majority of people do not notice differences between a Wave file and a FLAC file. However, they take up less space than WAV files. This is possible because they use a variable amount of compression as needed. This means that, in the case of very complex and rich music parts, it uses encodings that are equal to WAV files (1411 Kb / s data). However, in the case of the “simpler” parts, the number of bits used to represent them will be smaller. It is suitable for demanding ears who also want to save some space on their hard drives.
APE Monkey’s Audio is one of the most powerful and popular lossless multimedia compression algorithms for audio files.
The lossless format, that is without data loss, ensures that the original sound quality is maintained in smaller files than compressed sample formats (such as WAV).
The format used is “.ape”, Monkey’s Audio allows compression of a WAVin mono source and also the opposite procedure, ie mono decoding for other formats such as WAV or MP3
ALAC Apple Lossless Audio Codec: Similar to FLAC, which always uses maximum compression. The quality is good on average, but the format is not as effective as FLAC in terms of weight. Not all players support it, so if your life is not exclusively dedicated to Apple and its products, it’s not a recommended format. Other important but less popular lossless audio formats are Monkey’s Audio (.ape) and OptimFROG (.ofr).
AIFF Audio Interchange File Format is a standard file format used to store audio recordings on a personal computer. The format was developed by the Apple computer based on Electronic Arts electronic exchange format and is often used on Apple Macintosh systems, which is why it is also called Apple Interchange File Format.
The audio data in the AIFF file is not compressed, so the file tends to be much larger than other formats, both lost and lost, such as ALE or MP3. One minute sound records approx. 10 MB of data, this is because it is a format created for sharing, although it is also used for editing.
However, there are compressed formats, called AIFFC (AIFF compressed), that can reduce the file size by a third (AIFF3) or a sixth (AIFF6), but this results in a great loss of quality, so there is virtually no use.
The most important sound quality formats in loss quality.
MP3 (.mp3) or MPEG-1 or MPEG-2 Audio Layer III – is the best known compressed audio standard. It was the forerunner of the category (it was published as an international standard in 1998) and is still the most widely used. Minifying a WAV file to MP3 makes it up to 90% easier for MB. The quality varies depending on the bit rate, ranging from 32 to 320 Kbit information for every second of music. The default is 128 Kb / s. At 320 the performance is pretty good.
AAC (.aac) – Advanced audio coding. It’s an Apple standard that iTunes uses by default when importing music. It works like MP3, and with the same bit rate, it takes the same space. The difference is in the way compression is handled. In simple words, “music” sums up another way. According to many people it sounds better than MP3. Especially suitable for those who use iPhone and iPod to listen to music.
WMA (.wma) – This is a proprietary format from Microsoft and is considered Redmund’s response to MP3. Its incompatibility with the iPod makes it very uncomfortable. Incidentally, although most players support MP3, WMA does not. Basically, unless your music world starts and ends with Windows Media Player, it’s a generally discouraged format. It is not compatible with Mac and iTunes.
