Editor's note: A newer version is now available. Clicking the Buy button will take you to this version for purchase. We will evaluate, rank and review the new Stellar when we next update the Audio Converter Software reviews. Meanwhile, enjoy our review below about Stellar Audio Converter.

Stellar is one of the few converters we reviewed that is made for both audio and video conversions. When you first open the program, it prompts you to select between four different conversion options – Convert Audio, Convert Video, Video to MP3 or Rip Audio CD. The software is well-organized and simple to use. It has one of the fastest audio conversion speeds in our lineup. These are a few reasons why Stellar Audio Video Converter earns our Top Ten Reviews Bronze Award.

Ease of Use

The best audio converters are compatible with many different audio formats, but they can also convert audio files quickly. We timed each audio converter program as it compressed a 625MB WAV file to a 26MB MP3. Each program was timed using the same audio settings for each conversion, and only one program was run at a time. Our testing results showed that Stellar is among the fastest audio converters in our lineup. It was able to compress our large test sample in 1:04.5, which is the third-fastest conversion time –only one second behind the second-fastest audio converter. Fast conversion times can make all the difference at saving you time when you are compressing multiple large files in bunches.

Stellar is not just one of the fastest audio video converters in our lineup, it is also one of the easiest to use. We tested each program to see how many steps it takes to complete various conversion tasks such as ripping CDs and changing the output folder. We compiled all of the data from our testing and determined that Stellar is among the most user-friendly programs available. You can achieve most conversion tasks with just a few clicks of the mouse.

Audio Conversion Attributes

Most of the programs we reviewed, including Stellar, are able to convert audio files in batches, adjust the sample rate and bitrate of the converted audio, and change the channel settings for the converted audio. This means you can turn a stereo track into mono or vice versa. Some programs also allow you to adjust the volume or normalize the volume of your converted audio, which is especially useful when the original file is an older recording with low volume issues. We didn't find any normalization options within the software. This isn't detrimental, but this feature is offered with other programs.


One of the downsides to Stellar is that it is only compatible with and converts to seven different audio formats. That is the smallest number compatible audio formats in our lineup. Stellar covers all of the most popular formats – MP3, WAV, WMA, FLAC, OGG, AAC and MP4, but we were disappointed that the input/output capability isn't broader.

This software did excel in our video conversion testing. We tested each converter with M4V, MOV, MP4, MPG and WMV file formats. Stellar was able to extract the audio data from all of the video files that we tested. You can also use this software to convert video file formats to different formats.

Help & Support

Stellar features outstanding help and support options. It is one of the only websites that features live chat support. We waited in the chat queue for bit, but once we were connected with an operator, he was very helpful at answering all of our questions.

The email support staff responded to our inquiry promptly. They responded within 24 hours and answered our questions completely. Stellar showcases one of the best tech support teams we came across.


Stellar is one of our top performers for music converters. It can convert both audio and video as well as ripping CDs, and does it all within a user-friendly interface. Its biggest downfall is its limited audio compatibility, but the program does convert the most common audio file formats. Stellar is available on PC platforms and is one of the most inexpensive audio converters available.
