32-bit float and 24-bit: comparative testing with the Tascam FR-AV2 and Sound Devices recorders

Throwback

Well-known member
Probably more for sound effects recording than, say, dialogue recording, but I've been dipping my toe in the water of (dual-AD) 32-bit recording with the Tascam FR-AV2: I was after a very small two-channel recorder, and this was an opportunity, on the side, to also explore a dual-ADC design. And when I say 'explore', I mean compare exactly what this brings vs my existing recorders: a first-generation MixPre-3 and a pair of 788Ts. So, with this distinct and personal angle - and not pretending to be an all-encompassing review of the FR-AV2 (I would be rather late to the party for that!) or a comparison to budget 24-bit recorders - I have done a write-up of tests, with the usual downloadable files. I found it interesting (not least the lack of audible evidence for the switching ADCs), and I hope some others may do and not necessarily for the FR-AV2 (for example, and long overdue, I demonstrate the first generation MixPre-3's remarkably low self-noise at all gain settings, which has implications for recordings with extreme variation in sound levels). Anyway, here's a link to the blog post for anyone interested: https://drbadphil.com/dual-adc-and-...to-the-sound-devices-24-bit-mixpre-3-and-788t
