How to record HDMI audio only with ClonerAlliance UHD Halo¶
The ClonerAlliance UHD Halo supports recording the HDMI embedded audio as a standalone audio file, without any video. This is useful for extracting audio from video sources.
When to Use This Feature¶
Concert or live event recording — Capture high-quality audio from a broadcast or playback source.
Lecture or presentation audio — Record the audio track from a video presentation.
Audio extraction — Isolate the audio component from an HDMI source for later use.
Output Format and Quality¶
File format: MP3
Available bitrates: 128 kbps / 192 kbps / 320 kbps
Select the bitrate under Menu → Record Settings → Audio Bitrate before starting the recording.
320 kbps — Recommended for high-quality audio capture.
192 kbps — A good balance of quality and file size.
128 kbps — Suitable for voice recordings or situations where file size is a priority.
Advantages¶
Small file size — Audio-only MP3 files are significantly smaller than video recordings, making them convenient for storage and sharing.
Simple workflow — No video editing is required; the audio file is ready to use immediately after recording.
Note
Make sure a storage device (USB or TF card) is inserted and detected before starting the audio-only recording.
