Audio-reactive lighting effects

One of HyperHDR’s unique features is visualization based on sound amplitude and frequency in your ambient ecosystem using a USB grabber. PCM digital capture devices are preferred, as there is no analog sound filter available at the input in the current version. To make it work, you must ensure that the grabber receives an PCM audio stream. Be aware that some amplifiers, like Denon, may block it in a typical configuration (using ARC/eARC is necessary in that case).

Let's configure the hardware first in the 'Effect' tab. On the following screen I selected Ezcap 269 device.
Do not confuse it with some other system devices.

Next we need to enable 'Activate' option and save our settings.

Navigate to the 'Remote control' tab and turn on video preview to verify result.

For the beginning use 'Equalizer' from the list to test if everything works OK.

If you activated & set up your grabber correctly and it receives a audio stream you should see jumping equalizer's bars. obraz

If the bars are standing still flat, something is wrong. It almost always means that your grabber is not receiving sound or the driver is unable to handle the given format (e.g. Dolby Audio instead of PCM) or the capture frequency (22kHz). Using the 'Equalizer' audio effect go to the 'Logs' tab to confirm this...

It’s a final confirmation: you have enabled an audio device and it works, but it provides no sound… only silence. Maybe you selected the wrong device, but more likely there is no audio on the grabber’s input (e.g. the amplifier blocked it) or there is an issue with the audio format.
