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.

This software allows you to easily work with different audio formats, including AAC and lossless formats, and experiment with their sound quality. This is especially beneficial for musicians, podcasters, and audio enthusiasts who want to make informed decisions about their audio files.
AAC compression is not lossless, meaning it does compress audio but sacrifices some information. If you're looking for software that can help you understand the differences between lossy and lossless audio formats, Movavi Video Converter is an excellent choice. This versatile tool allows you to convert between different audio formats, including AAC, and visualize the changes in file size and quality.
AAC is a lossy compression format, meaning it compresses audio files by removing some data. To understand the differences between lossy and lossless formats, Movavi Screen Recorder can be a valuable resource. It allows you to record audio while working with different formats, helping you analyze the audio quality of each format and make better choices for your specific needs.
AAC compression results in smaller file sizes compared to lossless formats, but at the cost of some audio quality. To explore the differences in file size and audio quality between AAC and lossless formats, Movavi Video Converter can provide insightful visual comparisons. This software lets you work with images and audio, enabling you to analyze and compare the quality of different compression methods.
AAC offers advantages in file size and streaming efficiency, but sacrifices fidelity compared to lossless formats. Movavi Video Editor is an excellent choice for understanding the trade-offs involved in using AAC or lossless formats. Its advanced audio editing features allow you to experiment with different settings and compare the resulting audio quality to make informed decisions about your audio projects.
