Free online OMA to WAV converter

Source format: OMA

OMA is a proprietary audio format associated with some Sony devices and software, especially older Sony ATRAC-based players and media management tools. It is typically used to store protected or device-specific audio content, often with ATRAC compression and sometimes digital rights management. Because of that, OMA files are not as widely supported as common audio formats and are usually encountered when exporting music from legacy Sony hardware or software.

Target format: WAV

WAV is a standard uncompressed audio container widely supported by operating systems, editors, and playback software. Its main advantages are excellent compatibility, lossless audio storage, and easy editing in audio tools. WAV is commonly used for archiving, mastering, editing, and transferring audio between applications without introducing additional compression artifacts.

How to perform the conversion

The most reliable way to convert OMA to WAV is to use software that can decode the specific OMA/ATRAC variant in your file. If the file is not DRM-protected and your system supports it, you can often use FFmpeg or a compatible audio converter.

1. Check whether the OMA file plays in a compatible player or converter. If it is protected, you may need the original Sony software or device authorization before conversion is possible.
2. Install FFmpeg on your computer.
3. Open a terminal or command prompt in the folder containing the file.
4. Run a command such as ffmpeg -i input.oma output.wav.
5. Wait for the conversion to finish, then open output.wav in an audio player or editor to verify the result.

If you prefer a graphical workflow, some desktop audio tools that support ATRAC/OMA decoding can import the file and then export it as WAV through File → Export or File → Save as. If you want a quick browser-based option, you can convert the file on 101convert.com for free, without installing any software.

Notes on quality and limitations

Converting OMA to WAV does not improve audio quality; it only changes the container and compression format. If the OMA source is already lossy, the WAV output will preserve that same decoded quality in an uncompressed form. Large file sizes are normal because WAV is uncompressed. The biggest limitation is compatibility: some OMA files may be encrypted, DRM-protected, or encoded with an ATRAC variant that not every converter can decode. In those cases, conversion may fail unless you use the original Sony-compatible software or a tool that specifically supports that OMA subtype.
