AVPreserve Releases interstitial – Free Error Detection Tool

AVPreserve is pleased to announce the release of interstitial, a new tool designed to detect dropped samples in audio digitization processes. These dropped samples are caused by fleeting interruptions in the hardware/software pipeline on a digital audio workstation. The Interstitial tool Follows up on our work with the Federal Agencies Digitization Guidelines Initiative (FADGI) to define and study the issue of Audio Interstitial Errors.

interstitial compares two streams of digitized audio captured to a digital audio workstation and a secondary reference device. Irregularities that appear in the workstation stream and not in the other point to issues like Interstitial Errors that relate to samples lost when writing to disc. This utility will greatly decrease post-digitization quality control time and help further research on this problem.

interstitial is a free tool available for download via GitHub. Visit our Tools page for this and other free resources.
