Though it's unlikely to change anyone's life, this basic audio converter delivers on its promise and offers a couple of unexpected features. MP3-OGG-WAV-WMA Converter transforms audio files among the four formats found in its name. Like any respectable utility of this sort, the program lets you select bit rate, sampling rate, and encode files using VBR compression. The interface is neither ugly or particulary beautiful, but it is completely self-explanatory. If you choose to convert files to the MP3 format, you can apply high-pass and low-pass filters, a feature we don't see every day. There's also a list of presets with checkboxes for AM, phone, voice, radio, and HiFi, but we couldn't figure out how they fit into the overall scheme of the program. The minimal help files offer no assistance on this matter. The demo limits you to 30 file conversions, but that's more generous than many competing utilities that won't even enocde full tunes. If you're only seeking an audio converter and nothing more, this software makes a satisfactory choice.
