The latest Zoom field recorders support 32-bit float recording and achieve a wider dynamic range than that (upwards of 210db) by having a circuit with two different ADCs.
Also, it's less about the absolute resolution, and more about the ability to boost the gain, often by a lot, while still having a wide and useful dynamic range after the fact.
- duped 4y agoColor me skeptical, that's a wider dynamic range than air
- batmanturkey 4y ago32bit FLOAT is 24 bits of audio data, and has the unique advantage of being the typical internal processing format of plugins and audio workstations, due to the desire for headroom while processing to avoid artifacts from overflows of various kinds, among other things. (Upsampling is also common before performing calculations that may alias or mirror.) The stacked ADC approach does allow for a wider overall dynamic range, but I would be skeptical of the physical transducers capabilities in using it all, but the 32-but float format here appears to be largely about lossless transfer to a DAW such that further processing is lossless, as we are not converting from int to float and back. This format could then be said to be useful as a master media format. The article in the OP is about a flac containing a 32-bit int audio stream, however, which appears less useful and not at all related to 32-bit float
