Sometimes, it can be frustrating when an OPUS audio file does not play properly on a device, media player, or application. OPUS is widely used for streaming and online communication because it offers good audio quality with a relatively small file size. However, it is not supported by every device or software.

If you need better compatibility, converting the file to another audio format can be a practical solution. This is where you may want to convert OPUS to AAC. AAC is a widely supported audio format that offers a good balance between sound quality and file size. It is commonly used for music, mobile devices, media players, and other applications. In this article, we will discuss the basics of OPUS and AAC, why users may need to convert between these formats, different conversion methods, and common mistakes to avoid.

What You Should Know About OPUS and AAC

Before learning how to convert OPUS to AAC, it is useful to understand what these two formats are and why they are used.

OPUS is a lossy audio codec designed mainly for internet streaming, voice calls, and real-time communication. It can provide good sound quality while keeping the file size relatively small.

AAC, or Advanced Audio Coding, is also a lossy audio format. It is known for providing good audio quality at relatively low bitrates and is supported by many devices, applications, and media platforms.

Because of its wider compatibility, many users choose to change OPUS to AAC when they need an audio file that works with a broader range of software, devices, or media players.

Why You Might Need to Convert OPUS to AAC

OPUS can be an excellent choice for online communication and streaming, but compatibility can sometimes become an issue. If your preferred device or application does not support OPUS, converting it to AAC can make the audio easier to use.

Some common reasons:

• Better compatibility: AAC is supported by a wide range of media players and devices.

• Convenient playback: Converted AAC files can be easier to play across different platforms.

• Smaller file size: AAC can maintain good audio quality while keeping the file size manageable.

• Editing support: Some audio editing applications work more conveniently with AAC than OPUS.

• Easy sharing: AAC is commonly accepted by various applications and platforms.

• Device support: AAC works well with many smartphones, tablets, computers, and other media devices.

However, it is important to remember that both OPUS and AAC are lossy formats. Therefore, converting from OPUS to AAC does not restore audio data that was already removed during the original OPUS compression.

Methods for Converting OPUS to AAC 

There are several ways to convert OPUS to AAC, and the best option depends on the number of files, available software, and your specific requirements.

Users who only need to convert one or two files may prefer a simple media converter. On the other hand, users working with multiple audio files may benefit from dedicated conversion software.

#1. Convert OPUS to AAC Using Professional Converter

A dedicated audio converter can make the conversion process easier, especially when you have multiple OPUS files to process.

For example, FreeViewer Batch Audio Converter Software can be used to convert audio files between supported formats. Its batch conversion functionality can be useful when you need to process multiple files instead of converting them individually.

The general process is straightforward:

1. Download and install a reliable converter on your computer.

2. Launch the software after installation.

3. Click the Add or Upload option and select the OPUS files.

4. Choose AAC as the output format from the available audio formats.

5. Select the destination folder for the converted files.

6. Click the Convert or Start button.

7. Wait for the conversion process to complete.

8. Open the output folder and play the AAC files to verify the results.

#2. Convert OPUS to AAC Using VLC Media Player

VLC Media Player is another option for users who prefer not to install a dedicated audio conversion application. Apart from playing different types of media files, VLC also provides conversion functionality.

The general steps are:

1. Open VLC Media Player on your computer.

2. Go to the Media menu and select the conversion option.

3. Add the OPUS file that you want to convert.

4. Choose the required output profile.

5. Select AAC as the output format if available in your VLC setup.

6. Choose a destination for the converted file.

7. Start the conversion process.

8. Once complete, open the output file and check whether it plays correctly.

VLC can be convenient for occasional conversions, although its available encoding options and workflow may be less convenient for large batches of files.

Things to Consider Before Converting OPUS to AAC

When you convert OPUS to AAC, selecting the appropriate output settings is important. Since both formats use lossy compression, choosing unsuitable settings may affect the final listening experience.

Keep the following points in mind:

• Select an appropriate bitrate according to your audio requirements.

• Make sure AAC is selected as the output format.

• Avoid repeatedly converting the same file between lossy formats.

• Save the converted files in a separate folder to prevent accidental overwriting.

• Check the sample rate and other available audio settings before starting.

• Always test a converted file before processing a large batch.

Common Blunders While Converting OPUS to AAC

Even though the process to convert OPUS to AAC is generally straightforward, users can sometimes make small mistakes that affect the output quality or cause unnecessary issues. Being aware of these common blunders can help ensure a smoother conversion process and better results.

• Choosing the Wrong Output Format: Make sure AAC is selected as the output format before starting the conversion.

• Using Incorrect Audio Settings: Check the bitrate, sample rate, and other available settings to get the desired output.

• Overwriting Original Files: Save the converted AAC files in a separate folder to avoid accidentally replacing the original OPUS files.

• Converting the Same File Multiple Times: Repeatedly converting lossy audio formats can lead to additional quality loss.

• Using Unreliable Software: Avoid unknown or untrusted converters that may affect audio quality or compromise file security.

• Not Checking the Converted Audio: Always play a few converted AAC files to confirm that the audio sounds and works as expected.

• Processing Large Batches Without Testing: When converting many files, test a small batch first to verify the output settings and quality.

End Note

In short, convert OPUS to AAC when you need better compatibility, convenient playback, or an audio format that is widely supported across devices and applications.

You can use a dedicated converter for a straightforward workflow and batch processing, or use a media player such as VLC for occasional conversions. Regardless of the method you choose, always check the output format and audio settings before starting the conversion.

Most importantly, keep your original OPUS files safely stored. Since OPUS and AAC are both lossy formats, maintaining the original files gives you a backup if you later need to create another version of the audio.
