Files with the IVC extension are associated with the Intervoice Audio format developed for recording human speech. IVC files are based on the Adaptive Differential Pulse Code Modulation technology which lowers bandwidth requirements for any signal-to-noise ratio.

The IVC file format is mostly used for computer telephony software. It is also used for compressing voice recordings that were originally created using a lossless file format. IVC files support a maximum 8-bit sampling rate and monophonic only audio data. However, they can be compressed using various schemes including both u-Law and A-law.

How to open IVC files

IVC files can be opened with Sony Sound Forge. The application is available for both Microsoft Windows and Mac OS platforms.
