Tips: AAC vs FLAC Format

Most of the people dealing with Audio formats go for lower formats because they don’t know good audio format conversion software. Hence, the result is installing a bundle of software for each separate conversion! AAC also is known as ADVANCED AUDIO CODING with the file extension (.aac) is the most preferred audio format after MP3. Both are lossy formats i.e. they are good for regular listening but are noticeably low-quality formats. FLAC is a lossless audio format with the file extension (.flac) which means that it has same audio quality as that of the original source file. It is compressed hence, saving space. It is the free and open source, so it comes in handy.

The Free Lossless Audio Codec (FLAC) is the most known lossless format, making it an excellent option if you desire to store/save your music in lossless. Unlike WAV and AIFF, it's been compressed, so it takes up a lot less space. However, it's still a lossless format, which means the audio quality is still the same as the original source, so it's much better for listening than WAV and AIFF. Advanced Audio Coding, also known as AAC, is similar to MP3, although it's a bit more efficient. That means that you can have files that take up less space, but with the same sound quality as MP3.

While you probably won't observe higher quality, lossless is exceptionally good for storing your music if later on, you plan on converting it to other formats. Since converting a lossy format to another lossy format (e.g., AAC to MP3) will produce files of noticeably lower quality. So, for archival purposes, we recommend FLAC.
