MP3 with a file size of 100 MB will be expanded to 500 or 600 MB in FLAC format.Īlthough higher compression levels require more CPU processing power, higher compression levels can be used to reduce the size of FLAC files. Compared with MP3, the size of FLAC files can be quite large. The size of FLAC can be reduced by up to 50% to 70%, but MP3 is only a small part of the file size of FLAC, only 20%. Size is the first thing that needs to be compared when talking about MP3 vs FLAC. Read this part carefully to know the difference between MP3 and FLAC. This part gives you some specific information about MP3 vs FLAC. Related post: Top 11 Ways to Convert FLAC to WAV for Free MP3 VS FLAC: What Is the Difference Between Them? The bit size is usually between 8 and 32 bits. The “quality” of FLAC is determined by the “sampling rate” and “bit depth”. Although the quality between 0 and 8 remains relatively the same, the encoding and decoding time is greatly increased, and the compression level for the CPU may be higher. Digital audio can usually be reduced to 50% to 70% of its original size and decompressed into the same copy of the original audio data if it is compressed by the FLAC algorithm, but the final size relies on how much the digital audio is being compressed.įLAC files use levels from 0 to 8 to determine the compression level, where 8 is highly compressed.

It is the abbreviation of Free Lossless Audio Codec, and it is a digital audio format with lossless compression. Part 4 formats the bitstream (called an audio frame), which consists of four parts: header, error check, audio data, and ancillary data.Part 3 quantifies and encodes each sample (called noise allocation), and the sample will adjust itself to meet the bit rate and sound masking requirements.Part 2 passes the samples to a 1024-point Fast Fourier Transform (FFT), then applies the psychoacoustic model, and performs another MDCT filter on the output.Part 1 divides the audio signal into smaller parts, called frames, and then performs a modified discrete cosine transform (MDCT) filter on the output.The MP3 encoding algorithm is usually divided into four parts. This can greatly reduce the file size compared to uncompressed audio. MP3 makes use of lossy data compression to encode data using inaccurate approximations and partial discarding of data. MP3 as a file format usually specifies a file containing an elementary stream of MPEG-1 Audio or MPEG-2 Audio encoded data without the other complexity of the MP3 standard. To begin with, what is MP3? It formally represents MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) and it is a coding format for digital audio.
