Auditory Presentation

ERTS supports the presentation of sine wave tones (Chrome only) and the presentation of external audio files that can be accessed via http per URL. The most accurate presentation of audio files is achieved using the ‘A’ tone type (Chrome only), which loads and decodes the entire audio file in advance before presenting it. If your audio files are very large or want to loop audio files, use the ‘S’ type which supports lazy loading as well.
