Audio synchronization is an issue any time two or more audio signals need to be compared. For instance, when measuring audio quality objectively, a reference audio signal is compared to an impaired version. In both cases it is critical that the two audio signals be synchronized in time. The presence of delays between audio signals can result in distorted quality measurements.

CRC-TimeSync is a Windows 95/98/NT4/2000/XP application that offers a simple solution to the task of audio file comparison and synchronization. The layout and controls of the graphical user interface provide the means to quickly establish sample accuracy between source files.

CRC-TimeSync also includes tandeming feature which greatly simplifies the task of recording audio materials when looped through external audio devices and codecs. The user needs only to specify the reference file and the number of generations desired. This can be used to measure, for example, the effect of multiple generations of audio encoding and decoding.

CRC-TimeSync is available as a standalone program or integrated with CRC-SEAQ (System for the Evaluation of Audio Quality). Files can be shared between the two programs, which together create a powerful audio testing software suite.
