How to Convert FLAC to AAC Losslessly - Win/Mac/Online Solutions

Converting FLAC to AAC losslessly is a challenge because AAC is mainly designed for lossy compression. However, the good news is that several solutions exist across Windows, Mac, and online platforms to achieve high-quality lossless conversion. This article will discuss the best software-based and online tools for converting FLAC to AAC losslessly.

Understanding FLAC to AAC conversion: What you need to know

• Compression type: FLAC uses lossless compression, and AAC uses lossy compression. It compresses audio data by removing parts of the audio that are imperceptible to the human ear.
• File size: FLAC preserves the original audio quality perfectly. However, AAC has to sacrifice some audio quality due to its smaller size.
• Audio quality: FLAC offers lossless compression, so the final audio file retains the original file's audio quality. On the other hand, AAC uses lossy compression, which can result in lower audio quality compared to the original file.

Now that you know the difference between the two file formats, we'll examine the top FLAC to AAC converter solutions for Windows, Mac, and Online in the next section.

Common issues and solutions in FLAC to AAC conversion

• Quality loss: One of the major issues during the conversion process is the loss of quality. This problem has a simple solution: Use higher bitrate settings, like 320 kbps, to minimize quality loss.
• Metadata loss: Sometimes, during the conversion process, the metadata may not transfer correctly. To counter this issue, you can manually rewrite the metadata after the conversion process.
• File compatibility: The AAC file may need to be compatible with specific devices or media players. To solve this problem, ensure the AAC files are encoded in the software's supported formats.
• File size issues: Sometimes, the AAC audio file may still be large, not achieving the appropriate size reduction. In such a scenario, you need to adjust between the bitrate and other encoding settings to get a balance between quality and size.

FAQs

1. How does the FLAC to AAC converter for Windows work?
2. The FLAC to AAC converter decodes and encodes the FLAC file back to AAC format. Software, like CapCut and others, conveniently handles this process. Users must import the FLAC file, adjust the settings, and export it as an AAC file. The encoder ensures that the audio quality is retained during conversion.
3. How to use the FLAC to AAC converter iTunes?
4. To convert FLAC to AAC using iTunes, you need to convert it into a format compatible with iTunes, like AIFF or WAV. Once converted, import the file to iTunes. Then go to "Preferences" and select "Import Settings." Under this tab, choose "AAC." Then right-click on the imported file and select "Create AAC Version." After this, your file will be converted to AAC format.
5. Is FLAC better than AAC?
6. No. FLAC and AAC file formats serve different purposes, so the choice between the two depends mainly on your specific needs and requirements. FLAC is a lossless format that preserves the audio quality without losing data. This makes it ideal for archival purposes. On the other hand, AAC is a lossy format, which reduces the file size at the expense of quality loss. So, it is suitable for streaming and listening to music on mobile devices. So, if you want a lower file size, go for AAC. However, use the FLAC file format for top-notch audio quality.
