anyone has an idea does shazam cope with time-axis not being linear/const? Think tapes, wow-and-flutter, speed-up-then-down-all-the-time.. AFAIK fingerprintin

anyone has an idea does shazam cope with time-axis not being linear/const? Think tapes, wow-and-flutter, speed-up-then-down-all-the-time.. AFAIK fingerprinting is highly time-sensitive (unless cut into ~50ms pieces.. and still not quite). Last time i looked, the general technique for that - Dynamic Time Warping ? - was prohibitely compute-expensive..
