Audio validation command

Validates audio input for MOS quality (WAV audio files only). The command receives an audio file that may have been recorded from a device and uses parameters to trim off any silence from the beginning or end of the audio. Using this trimmed file, it then executes an analysis service.

Important: This functionality is part of the Advanced Audio Package, a separate license that provides access to tools for testing a device's audio quality. For more information, contact your Perfecto account representative.
