Requires iPhone 16 Pro or newer.
'ab Spatial Recorder' is an advanced recorder of 1st Order Ambisonics signals LOSSLESSLY for Spatial Audio.
Requires iPhone 16 Pro/Pro Max and above!
Using your iPhone's built-in microphone array, you can now record Audio in 1OA Ambisonics losslessly.
The Ambisonics Audio can later be decoded to any speaker layout in existence: From Stereo all the way to 5.1, or even Dolby Atmos beds!
Additionally, 'ab Spatial Recorder' also includes a video recorder that helps you record video WHILE recording Ambisonics audio. That way you can record video and simultaneously have your lossless Ambisonics track. This track is also decoded inside the device and a Stereo audio signal added to the final video. That way, you have your video with stereo audio and your lossless Ambisonics WAV.
'ab Spatial Recorder' comes also with a media player that helps you visualise, and listen to your 1OA recordings in Stereo, so you can watch or listen instantly!
Included:
- Lossless 1st Order Ambisonics recording, straight from your iPhone's microphone array.
- Video recording, with your Ambisonics track decoded to Stereo and added to the video for you.
- A built-in player to watch and listen to your 1OA recordings in Stereo, instantly.
- Recorded Audio can be 16-bit, 24-bit, or even 32-bit Float at 48kHz.
- Video can be all the way from SD, to 1080p and even 4k, at 24, 30, or 60fps.
- Recordings can be done in portrait mode, or in landscape mode - the Ambisonics soundfield will adapt to the orientation of your device.
- Video Stabiliser can be turned on or off.
- Cameras can be flipped together with the Ambisonics soundfield, meaning that you can use your selfie camera as "Front" or your main cameras as "Front" - it all depends on what YOU want!
Available as separate add-ons:
- GPS Tagging - a GPS tag saved in both your video and your audio files, so you always have the location where the media was recorded.
- Dual Camera - record BOTH cameras at once, so you can see what's happening in front of and behind the device, great for tracking audio. Works in PiP mode or in DOUBLE 4K!
- Real-Time Audio - decode the audio to Stereo in real time and write it into your video file while you record, for instant results.
- Immersive Formats Export - IAMF Audio, to create spatial videos you can upload to YouTube, plus Apple Spatial ASAF.
- Advanced Camera Controls - for professional takes (Log, Log2, HDR, P3, manual ISO, shutter speed, white balance, focus options, zoom curves - all based on device support).
- Soundfield Rotation - rotate your Ambisonics files manually or through head rotation (AirPods).
