ClockDrift: On-the-fly measurements of clock drift in multimedia devices

Over the last year, I’ve been extensively researching and wasting time on an effect called clock drift in the multimedia domain. Clock drift is the deviation of a clock’s speed from the word time standard‘s speed, resulting in shifts in sampling rates, and this shift leads to parallel recordings from different devices not being synchronizable without manual post-processing. Because each recording is sampled a bit differently, they all run at a slightly different speed when played back in parallel on a single device, like it happens in a non-linear editing system on a computer workstation. To conclude this topic, I have just published an Android app called ClockDrift, which helps to measure drift in multimedia devices. I have also written an accompanying ClockDrift App User Guide and a general introduction into the topic, Clock Drift in Multimedia Recordings.
