Capturing decent audio can be a challenge, as it relies on both tools and technique. Editing and enhancing audio is often difficult and dependent on audio software that can be very costly. As we develop engaging courseware that incorporates natural sounds (how-to or interviews on the plant floor) to scenarios involving multiple voices (a sales call or performance appraisal), getting the sound right is critical. Poor audio is distracting, and your learners will tune out.
