The Digital Audio Capture (DAC) app is a free app developed by College Board and ETS to use for recording students’ audio responses for the AP Music Theory Exam and AP French, German, Italian, and Spanish Language and Culture Exams. This app has been developed to simplify the recording process for students and proctors, utilizing current technology that is intuitive to most students. It streamlines post-exam tasks for school staff by directly uploading student audio files after recording. School staff will follow the instructions in the 2025-26 AP Exam Instructions book to administer an exam using the DAC app. NOTE: The DAC app is limited for use on school-owned and -controlled iPad tablets (iOS 15.0 and above). Schools must update to the 2026 version of the DAC app; previous versions of the app will not work in 2026.
