Interstitial is a free and open source tool that detects the common problem of dropped samples, resulting in lost audio, as a result of malfunctioning audio digitization systems.
These dropped samples are caused by fleeting interruptions in the hardware/software pipeline on a digital audio workstation.
Sample Level Detection
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, which relate to samples lost when writing to disc. This utility greatly decreases post-digitization quality control time and will assist further research on this problem.
The Interstitial tool follows up on our work with the Federal Agencies Digital Guidelines Initiative (FADGI) to define and study the issue of Audio Interstitial Errors and system performance testing.
