FLAC is the abbreviation of Free Lossless Audio Codec, a popular audio format for its excellent audio quality. On one hand, it is one of the most preferred audio formats for music enthusiasts and audiophiles. On the other hand, it has an intriguing factor that often leads to a question: "Why are FLAC files so big?" Fortunately, in this article, we will delve into the technical aspects of the FLAC format and add to its lossless nature, compression, and the reason that results in its big size appearance. Thus, if you want to cut to the chase, you can already jump into the entire content below.

FLAC Files so Big

Part 1. Reason Why Are FLAC Files So Big

The main reason FLAC audio files are huge is their lossless compression designation. This means the files are made to maintain all the audio data from the source in its original state. To explain further, here are some factors that explain why FLAC is big.

Lossless Compression

FLAC audio compression is lossless, maintaining all the original audio data from its original source. The preservation of the original audio data results in a larger size of the file. This contrasts with the lossy compression that popular formats like AAC and MP3 have. Such formats discard some audio data to get smaller target file sizes.

High Audio Quality

FLAC files are known for their high quality, making them larger. However, this is also the reason why many audiophiles choose this format over other audio formats.

Variable Sample Rate and Bit Depth

FLAC supports sample rates and bit depths, which are variables. These allow their recording quality to be high. The higher the sample rates and bit depths, the higher the data amount is stored in a file, making it larger in size. This is also the best FLAC compression level, making it big.

Audio Complexity

The length and complexity of the audio content can also affect its file size. A piece of music that has a lot of instruments, elaborate details, and a longer span results in a larger file.
