.Sh DESCRIPTION
|
|
.Nm sndfile-interleave
|
|
creates a multi-channel file taking audio data
|
|
from two or more mono files as individual channels.
|
|
The format of the output file is determined by its filename suffix.
|
|
The audio parameters of the output file will be made so that
|
|
the format can accommodate each of the mono inputs;
|
|
for example, the samplerate will be the maximal samplerate
|
|
occurring in the inputs.
|
|
The output file will be overwritten if it already exists.

|
|
where
|
|
