What is a .vox file?
File extension details and usage information
The VOX file format is a specialized audio file format primarily used for storing digitized voice recordings. It was developed by Dialogic Corporation and is widely utilized in telephony applications, such as interactive voice response (IVR) systems, voicemail systems, and automated telephone answering machines. The format typically uses Adaptive Differential Pulse Code Modulation (ADPCM) compression, which is a lossy compression technique designed to reduce the file size of speech recordings while maintaining acceptable quality for human voice recognition. Because it is optimized specifically for voice frequencies, it is not suitable for high-fidelity music reproduction. VOX files are usually stored as raw data without a header, meaning that applications opening these files must be pre-configured with the correct sample rate, bit depth, and number of channels to interpret the audio data correctly. While it has been largely superseded by more modern, flexible formats like WAV or MP3, it remains a legacy standard in many telecommunications infrastructures.
