Question: what is the difference between 24 bit and 32 bit float?
Answer: So compared to a 24-bit WAV file, the 32-bit float WAV file has 770 dB more headroom. ... Each audio sample for 32-bit float files consumes 32 bits of space on a hard disk or memory, and for a 48 kHz sampling rate, this means that 32 x 48,000 = 1,536,000 bits per second are needed for 32-bit, 48 kHz files.
