Aya All to MP3 / WMA / AAC / M4A Audio Converter is an application with a title that pretty much explains its purpose - it allows you to encode media files to audio tracks with various formats, including MP3, WMA and AAC.

The interface of the program is plain and simple to work with. Media files can be imported into the list by using the file browser only, because the "drag and drop" method is not supported. Batch processing is not allowed in the unregistered version.

In the queue you can check out the source path, duration, start and end time, along with status of each file. So, after you establish the output destination and profile, you can proceed with the encoding job.

But you can also change audio preferences when it comes to the bit rate, channel mode, sample frequency rate and volume, as well as grab a file from YouTube, move items up and down in the list and clear the queue.

The simplistic audio conversion software requires a very low amount of system resources (which is barely noticeable), has a good response time, quickly finishes a task and manages to keep a good sound quality in the output tracks. You can also check out an online step-by-step guide with snapshots.

However, the fact that batch processing is not allowed in the unregistered version is a major downside. Also, the interface is slightly outdated and we weren't able to grab files from YouTube. We recommend Aya All to MP3 / WMA / AAC / M4A Audio Converter with some reservations.
