Extract text from compressed audio files (WA_)
To convert WA_ audio files to another format, you need Microsoft Windows or other Compressed software.
To convert other file formats to the "Legacy Installation Archive" file type, you need software like Microsoft Windows or a similar tool.
The .wa_ file extension represents a compressed WAV (Waveform Audio) file. It uses the legacy Microsoft Cabinet (CAB) or LZ77 compression algorithms. These files were heavily utilized in older versions of Microsoft Windows (such as Windows 3.1, 95, and 98) to save space on installation floppy disks and CD-ROMs.
You cannot play a .wa_ file directly. You must first decompress it using the Windows command-line utility expand.exe or a third-party archive tool like 7-Zip. Once extracted, the file becomes a standard uncompressed WAV file.
The primary disadvantage of the .wa_ format is that it is essentially a closed, obsolete system archive. Modern media players, web browsers, and mobile devices cannot read the compressed audio stream inside the container. If you simply rename the extension to wav, the file will remain compressed and will fail to open.
The immediate conversion target is an uncompressed WAV file. From there, users typically convert the audio to modern, lightweight formats like MP3 or AAC for broad device compatibility and internet distribution.
Because this file is a compressed installation archive rather than a standard audio file, regular online audio converters will fail to process it. Just drag and drop your file to identify the format, view its internal structure, and convert it when possible. convert.guru can inspect the archive headers, identify the Microsoft compression method, and if supported, extract the underlying audio for viewing or conversion.
Convert.Guru analyzes your WA_ file, detects the exact format, and lets you read the text inside.
Users also converted WMA, MIDI and WMDB files.
If you want to convert WA_ file to MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC, APE or WV, you can use Microsoft Windows or similar software from the "Compressed Audio Archive" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to WA_, try Microsoft Windows or another comparable tool in the "Compressed Audio Archive" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WA_ converter.
