Audio file formats play a crucial role in how we listen to and store music. The need to switch from one format to another arises for various reasons, such as compatibility with different devices or for achieving higher audio quality. This is where the process of converting AAC files to FLAC becomes relevant. AAC, known for its efficiency in streaming and compression, is a common format. However, FLAC, standing for Free Lossless Audio Codec, offers uncompressed audio quality, preserving the original sound without any loss.

If you're looking to convert AAC to FLAC, there's a simple and free solution available online. Online Video Converter provides a user-friendly platform for this purpose. With this tool, you can easily learn how to convert AAC to FLAC online for free. The process is straightforward: upload the AAC file, select FLAC as the output format, and let the converter do the rest. This tool enables you to convert AAC to FLAC for free without the need to download any software, making it an accessible option for everyone.

The need for such conversion often arises for audiophiles who seek the purest sound quality. FLAC files retain the original audio data, which is ideal for high-end audio systems and for archival purposes. Additionally, converting to FLAC can be beneficial if you're planning to edit the audio, as it provides more flexibility and better quality for post-processing. This conversion process does not compromise the sound quality, unlike other compression methods, which makes it an excellent choice for preserving the integrity of your audio files.

What is AAC?

Full name

Advanced Audio Coding

Format type

Audio

Developed by

Fraunhofer, Dolby, Sony, and others

Description

AAC, which stands for Advanced Audio Coding, is a widely used format for audio compression and the most common audio format for Apple devices. The AAC file type was created as a substitute for MP3. Generally, AAC provides better sound quality than MP3 at similar bitrates. Many devices, including Apple and Android, support AAC. But if you want to play your audio collection on another device without iTunes, your best option is to change the format of your files to MP3, which is still used almost everywhere. Check the list below if you’re not sure how to open AAC audio files and which programs support playback of these files.

File extension

.aac, .m4a, .m4p, .m4b, .mp4, .3gp

Technical details

Files with the AAC specifications enable temporal noise shaping, non-uniform sampling, and bitstream reformatting for 16 stereo, 16 mono, 16 low-frequency channels, and 16 annotation channels in a single bitstream. In 1999, the AAC format was included in the MPEG-4 Part 3 format, after which AAC added support for audio object types and permanent noise replacement technology. AAC is currently described in the ISO / IEC 14496-3 standard.

What is FLAC?

Full name

Free Lossless Audio Codec

Format type

Audio

Developed by

Xiph.Org Foundation; Josh Coalson and Erik de Castro Lopo

Description

FLAC is short for Free Lossless Audio Codec. It was created in 2001 by the Xiph.Org Foundation but didn’t have a stable release until 2019. FLAC is useful when you want to compress audio without losing quality. But, like other high-quality formats, files with FLAC specifications can be huge. If your device doesn’t have much storage space, you might have problems maintaining a collection of FLAC files. Despite its popularity, media players like iTunes and QuickTime still don’t support audio playback of the FLAC format, and many mobile apps cannot decode it. You may want to consider converting your FLAC files to the more widely supported MP3 format to be on the safe side. Check the table below if you want to know how to open FLAC audio tracks and which programs can play them.

File extension

.flac

Technical details

Although FLAC files are compressed, they are of the same quality as the source audio. The audio files in lossy formats like MP3 or AAC have slightly worse sound quality than those of lossless formats. However, the difference may be almost undetectable if the lossy file has a high bitrate. Another feature of the FLAC file type is that it uses IDv1 and IDv3 tags. This allows the user to arrange their audio collection according to taste, changing the original track metadata.
