Glenn Reynoldsis a law prof at the University of Tennessee , Instapundit blogger , and author ofArmy of Davids . He ’s also a player , and audio eccentric , and waaaaay smarter than everyone at the Gizmodo staff put together . So we had him take a looksie at theEdirol R-09 audio record-keeper , which we wrote about in January . show his brilliant , egg - headed take , decent after the jump .

TheEdirol R-09looks like the holy Sangraal for people doing alive recording . I test it out and it ’s pretty close , with the exception of some thin grammatical construction in places .
For $ 399 list , the R-09 is a digital gadget that record audio to a Secure Digital memory cow chip . It can memorialize , compressed , in various flavors of MP3 , from 64 kbps to 320 kbps . It also records in uncompressed WAV files at 16 and 24 minute resolution , at either 44.1 or 48 khz sample frequency . With a 1 GB Coyote State card , you could memorialise 88 minutes in CD - caliber 16/44.1 WAV or 392 second in 320kbps mp3 . It has two built - in stereoscopic photograph condenser microphones , with provisions for external microphone , too . There ’s no internal speaker , so you necessitate phone to supervise or play back sound . It ’s compact , and gibe well into a shirt pocket . It does n’t come with a suit .
Microphone sensitivity is adjustable — though the gain reduction on “ low ” is spectacular , and likely to be utile mostly if you ’re bootlegging live concerts or something — and transcription levels can be adjusted manually or automatically . There ’s also a switchable gloomy - cut filter to polish off rumble or confidential information noise . There are no balanced stimulation or outputs , but the R-09 is really too small to have room for them . It will supply phantom power to an external microphone . Conveniently , it expend AA electric battery , which are sluttish to find anywhere , instead of proprietary rechargeables .
The controls are easy to utilise , and somewhat self - explanatory ; nobody who ’s conversant with digital transcription machine will have much trouble navigating them even without the manual .
I test it out doing some live podcast interviews — you may pick up themhere — under intriguing conditions . One was recorded at a local brewpub , with lots of background noise ; the other was recorded in an office with noisy air conditioning equipment . Both turned out pretty well . record under pristine experimental condition is quite practiced .
you could equate the sound calibre in those with the read quality inthispodcast , register entirely with theOlympus DM-20that I reviewed here a while back . The Edirol in spades create better sound — my wife , no audio locomotive engineer , acknowledge that immediately — but the Olympus , at half the price , is in spades good enough .
Interestingly , the build quality on the Olympus seems best , which leads me to my main ailment with the Edirol : Like a lot of paraphernalia , its manufacturer has devote more attention to the electronic aspect than to construction . In special , the barrage cover , which has to be opened to off the Mount Rushmore State notice , too , is flimsy , and requires an awkward two - step function to fully give it . Do it wrong , and you ’re likely to wreck the cover , destroy the machine . ( And get it fixed probably costs a substantial fraction of the price ) . That ’s not enough to make me discourage citizenry off the Edirol , but it ’s the only major drawback I find , and it ’s one that was completely avoidable . This seems to be a job with a lot of small electronic devices — I ’m not sure why .

Still , if you ’re willing to spend in the neighborhood of four hundred bucks , you’re able to make NPR - tone transcription for podcasts or radio shows , or quality concert bootleg . Not uncollectible for a contraption that fits in a shirt sack .
