Configure Audio Preprocessing Tasks

When you configure a task that uses the audiopreproc module, you must use the appropriate mode for the task that you want to perform. The following modes are available:

A Audio categorization.
C Clipping detection and assessment.
S Signal-to-noise ratio calculation.
T DTMF dial tone identification.

You can use one or more of these modes in a single schema. To use multiple modes, type the letter for each mode in the schema, without spaces. For example:

1 = w1,d <- audiopreproc(CATS,a)

This example uses all four of the audiopreproc module modes to analyze audio.
