Musical excerpts (hooks) are played to a group of 60 to 120 persons that are representative of the (target) audience of the radio station commissioning the study. The test persons rate the music by completing a form or turning the dial of a measuring device. Advantage: A large number of songs can be tested in a single evening (up to 800 hooks). Disadvantage: The test persons have to travel to and from the venue and invest a certain amount of time. Auditorium tests are suitable only for small homogenous areas (e.g., test persons from Zurich and its surrounding area).
The Mediapulse Corporation has carried out several auditorium tests with the MixMaster system in cooperation with the US company Broadcast Architecture (BA).

Rating with grades: The test persons rate the music by turning the dial of the radio-controlled MixMaster device to a greater or lesser extent. The rating scale goes from 0 to 100.

Curves instead of figures: The BA computer processes the awarded grades and displays them in the form of curves similar to those of an ECG.

Live test results: The test results can be transferred to a screen in an adjoining room and followed by the test observers, who can hear the same music as the test audience and see the ratings as they appear. The test results are also made available in print and electronic form.
