Apply Spatial Playback processing to QTA files in Logic Pro for iPad
Logic Pro for iPad can apply various processes to an audio file encoded in the QuickTime Audio (QTA) format. Recording audio on an iPhone 16 Pro/Max or later creates such a file with the .qta extension. The four microphones on the iPhone capture a spherical sound field encoded into a four-channel FOA (first order ambisonics) file that is used as the raw source material for Logic Pro processing.
When importing such a QTA file into Logic Pro you can play it back, rendered in real time to mono, stereo, or surround (up to 7.1.4). In addition, with spoken words or vocal recording, you can apply real-time voice enhancements, for example, separate vocals from the instruments, or separate a voice from the background sounds, such as wind, noise, or traffic. By adjusting the degree of isolation, you can lower the background or completely remove it. This is a powerful tool to reduce or remove a bad room sound in a voice recording or remove the voice to use only the ambient sound.
Note: The minimum system requirement for Spatial Playback in Logic Pro for iPad is iPadOS 26.
Import a QTA file into your project
Drag the .qta audio file from the Files app to Logic Pro below the last track in the Tracks area.
The Region inspector now shows the Spatial Playback section when selecting the new region.
Change the playback mode of a QTA file
In Logic Pro, select the QTA audio region.
In the Region inspector, tap the Spatial Playback disclosure triangle to show those parameters.
Tap the Voice Isolation switch to deactivate it.
Tap the Format pop-up menu and choose one of the two playback options:
Mono: The ambisonics content of the QTA file is played back as a mono signal.
Stereo: The ambisonics content of the QTA file is is played back as a stereo signal.
Isolate the voice from the background during playback
In Logic Pro, select the QTA audio region.
In the Region inspector, tap the Spatial Playback disclosure triangle to show those parameters.
Tap the Voice Isolation switch to activate it.
Tap the Mode pop-up menu and choose one of the options:
All Voices: Voices are separated from the other elements in the recording.
Studio Voices: Separates the voices with a higher quality.
Remove All Voices: Only keeps the ambience or instruments and removes all voices.
Drag the Ambience Removal value slider to adjust how much of the ambient sound or instruments you want to remove from the voice recording.
This parameter is not available when the Mode parameter is set to Remove All Voices.
