Export your audio as a WAV file at 16-bit (CD standard), 24-bit (studio standard), or 32-bit float — useful when a DAW or plugin expects a specific bit depth.
The Bit Depth Converter changes the resolution of each sample: 8-bit lo-fi, 16-bit CD quality, 24-bit studio or 32-bit float for maximum headroom. Fewer bits means a smaller file and a higher noise floor; more bits means more dynamic range and headroom for editing.
When you reduce the depth, optional TPDF dither converts the harsh distortion of rounding into a faint, steady hiss — the right thing to do for any 16-bit export.
Each sample is scaled to the integer range, rounded and rescaled; with dither, triangular-probability-density noise of ±1 LSB is added before rounding so quantisation error becomes uncorrelated with the signal. Theoretical dynamic range is about 6.02 dB per bit: 8-bit ≈ 48 dB, 16-bit ≈ 96 dB, 24-bit ≈ 144 dB. 32-bit float stores samples as IEEE floats with ~1,500 dB of range and no clipping inside the file.
Reduce 24-bit to 16-bit with dither.
8-bit crunch.
Reduce 24-bit voice recordings to 16-bit.
Save 32-bit float to avoid clipping during processing.

Masks quantisation distortion with benign noise.
For recording and editing yes (headroom); for listening 16-bit is already beyond most ears.
No — if your source file was already lower resolution (like a 16-bit MP3-derived file), converting up doesn't recover detail that was never captured. It's most useful for giving further edits more numerical headroom, or matching a required format.
16-bit is standard for finished, distributed audio (CDs, most streaming). 24-bit is the norm for recording/mixing sessions, giving more headroom before rounding errors matter. 32-bit float essentially removes the risk of internal clipping during heavy processing.
