Maggie, The only thing missing from that expensive box is a 12 digit frequency display to show all the zeroes that the customer just paid so much money for. An accurate clock is somewhat useful, but the audiophile way is to spend a lot of money to optimize some unimportant parameter way too far while ignoring the basic things. Considering that only rarely is a recording more than an hour long, having sample timing accuracy for an eight-day-long recording is overkill. Also, it's hard to find a person capable of detecting the pitch error caused by any crystal oscillator being out of whack by the typical .01% of a cheap microprocessor crystal. That's less than a tenth of a Hertz at middle A! However, if you want the best for your mastering studio, a $100 ebay surplus ovenized crystal will get you to .00001% accuracy easily, with lower jitter than a phase-locked rubidium oscillator. -- --David Forbes, Tucson, AZ http://www.cathodecorner.com/ _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
