+\fBFormat Conversion\fR
+.br
+Converting an audio file from one format to another with
+.I SoX
+is "lossless"
+(i.e. converting back again would yield an exact copy of the original
+audio signal)
+where it
+can be, i.e. when not using "lossy" compression (e.g. A-law, mp3, etc.)
+and the number of bits used in the destination format is not less than
+in the source format.
+
+E.g. converting from an 8-bit PCM format to a 16-bit PCM format is
+lossless but converting from a 24-bit PCM format to a 16-bit PCM format isn't.
+When performing a lossy conversion,
+.I SoX
+uses rounding to retain as much accuracy as possible in the
+audio signal.
+.P
+\fBClipping\fR
+.br
+Clipping is distortion that occurs when an audio signal
+level exceeds the range of the chosen representation.
+Clipping is rarely desirable and so should usually be corrected by
+adjusting the audio volume prior to the point at which clipping occurs.
+
+In \fISoX\fR, clipping could occur, as you might expect, when using the
+.I vol
+effect to increase the audio volume, but could also occur with many
+other effects, when converting one format to another, and even when
+simply playing the audio.
+
+Playing an audio file often involves reampling, and processing by
+analogue components that can introduce a small DC offset and/or
+amplification, all of which can produce distortion if the audio signal
+level was intially too close to the clipping point.
+
+For these reasons, it is usual to make sure that a digital audio
+file's signal level does not exceed around 70% of the maximum (linear)
+range available, as this will avoid the majority of clipping problems.
+\fISoX\fR's
+.I stat
+effect can assist here by displaying the signal level in an audio file.
+
+If clipping occurrs at any point during processing, then
+.I SoX
+will display a warning message to that effect.
