As in previous years, the 2010 RMAF featured a full program of seminars. I moderated two of them, the first of which on Saturday morning featured Channel D's Rob Robinson demonstrating how to rip LPs to your PC. Rob flew by the seat of his pants, doing everything in full view of the packed houseincluding booting-up his Mac mini, hooking up a Music Hall turntable to a preamplifier/ADC and connecting the preamp to the computer with a FireWire linkto make the point that there was nothing intimidating about the process. (His and my thanks to AudioEngine for providing powered speakers to allow the audience to hear what was happening.) The only departure from orthodoxy was that as Robinson was using Channel D's Pure Vinyl program (reviewed by Michael Fremer last August) to capture the data, he was using the program's digital-domain RIAA correction so used a flat-response preamp rather than a true phono preamplifier.
What I found especially fascinating was that with the first LP he rippeda 45rpm reissue of some classic Elvis Presley songs that he just purchasedthere was spectral content on some finger pops going all the way up to 100kHz! Robinson was therefore ripping the LP at 192kHz in order to preserve the waveform cut into the LP's grooves with as much accuracy as possible. Those who argue that even 44.1kHz is overkill for ripping LPs, please take note.
