Hva er Surround Generator-appen? Surround Generator is an audio signal generator for Apple TV that can send test signals to specific speaker channels. The app has Dolby Digital 5.1, 7.1, and Atmos (optional) test signals available in several types.

Use these signals to test, calibrate, and adjust your sound system for the best audio experience possible. You will need a system for analyzing the test signals both in frequency and level. They are designed specifically for the iOS app AudioTools, which has a number of test and measurement modules available, but may also be used with other test & measurement platforms.

Formats include 5.1 surround, 7.1 surround, and optionally Atmos 9.1.6 test signals. Apple TV 4k is required for Atmos signal support.

Note: This app does not include any testing capabilities, other than being able to make sure that your speakers are assigned to the correct channels, left, right, center, surround, and height.

The test signals in Surround Generator include:

● Full-Band Pink Noise for Frequency Response Tests
● Mid-Band Pink Noise for Level Tests
● Impulse for Time Delay and Room Acoustics Tests
● Speaker Polarity Test Signal
● 7-second Impulse Response Sweep Signal
● 0.5s LARSA Chirp Signal
● LARSA Delay Test signals for subwoofer time-alignment
● Sine wave generator in Stereo mode, 10Hz-2000Hz sweepable

Note that you have to have surround sound and Atmos set up in your Apple TV and audio processor or receiver to be able to use this app.
