32-bit ﬂoat WAV ﬁle overview

32-bit ﬂoat WAV ﬁles have the following advantages over conventional 16/24-bit WAV ﬁles.
These features enable the quality of the sound during recording to be maintained even during post-
production.

Resolution advantage

32-bit ﬂoat WAV ﬁles have the advantage of being able to maintain high resolution even at low volumes. As
a result, quiet sounds can be made louder when editing after recording without degrading their quality.

16/24-bit WAV

Volume raised

■

32-bit ﬂoat WAV

Resolution high

Clipping advantage

If a waveform sounds clipped when output from the M2 or in a DAW, it can be edited after recording to
lower its volume and restore an unclipped waveform because the data in the 32-bit ﬂoat WAV ﬁle itself is
not clipped.
