Extract text from Audio files (AUDIO)
To convert AUDIO Audio to another format, you need WhatsApp or other Audio software.
To convert other file formats to the "Cached Audio & Asset Bundle" file type, you need software like WhatsApp or a similar tool.
The .AUDIO file extension is heavily fragmented and is primarily used as a temporary cache container for WhatsApp Messenger or as an audio asset bundle within video games developed with the Unity engine. In the case of WhatsApp, these files are often standard MPEG-4 audio files deliberately renamed to bypass media gallery auto-indexing. For gaming, companies like Bandai Namco or classic studios like Westwood use the .AUDIO extension to store compressed Vorbis tracks or proprietary audio matrices.
Users typically need to convert these files because standard media players and web browsers will not recognize the .AUDIO extension, leading to playback failures. Relying on these files for long-term storage is a massive disadvantage: they are highly application-dependent, lack standard metadata tags, and can be easily wiped by cache-clearing apps on your device. Additionally, if the file is a UnityFS bundle, it cannot be played directly - it requires a dedicated extractor before the actual audio tracks can be exposed to a media player.
The best target formats for conversion are MP3, M4A, or WAV. Converting a WhatsApp .AUDIO file to M4A is often completely lossless because the underlying data is already encoded as AAC within an MP4 container. For game assets, extracting and converting to MP3 or OGG ensures universal compatibility across all modern devices, though you may lose specific game engine looping metadata.
Because the .AUDIO extension does not guarantee a single standard format, traditional online converters often fail instantly when encountering it. They look at the extension instead of the file's internal signature. Game asset bundles are completely closed and proprietary, meaning standard audio decoders cannot parse the header. Our analysis engine reads the raw bytes to detect if it is a hidden MP4 stream or a packed UnityFS archive, allowing for direct viewing or extraction if the embedded format is supported.
Convert.Guru analyzes your AUDIO file, detects the exact format, and lets you read the text inside.
Users also converted UNKNOWN, NIB 2, M4A, REX, MP4, MP3, STRINGS, MPEG, RMX, OPUS, DSS, 1 and 2 files.
If you want to convert AUDIO file to MP3, TEXT, VIDEO, MIDI, WAV, MP4, AAC, FLAC, OGG, WMA, M4A or AIFF, you can use WhatsApp or similar software from the "Application Audio Cache & Assets" 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 AUDIO, try WhatsApp or another comparable tool in the "Application Audio Cache & Assets" 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 AUDIO converter.
