The HOLOSOUND immersive audio processor DCAP-OBIA is the core part of HOLOSOUND. Its main function is to decode, process, render and EQ the audio signal through powerful internal processing power, and then transmit the processed audio data to digital power amplifier or to Digital to Analog Converter. With the use of DAC and digital power amplifiers developed by LEONIS, up to 128 sound objects or channels can be played simultaneously. DCAP-OBIA can support up to 256 channels output, which is 4-16 times larger than other immersive audio technologies.

Performance Advantage

It has seven advantages:

1)  HOLOSOUND, the Object-based Immersive Audio Technology, can achieve continuous movement of sound, rather than simple multi-track expansion.

2)  HOLOSOUND, revolutionizes the presentation of sound in three dimensions（3D）rather than two dimensions(2D).

3）Fully compatible with related specification/standard.

4）HOLOSOUND, can support up to 256 speakers, which is 4-16 times that of other object-based immersive audio technology.

5）HOLOSOUND supports Bottom Surround Speaker beside Overhead Surround Speaker and Side Surround Speaker.

6）HOLOSOUND supports Point Sources to allow driving of individual speakers, not just arrays of speakers.

7）Other OBIAs only supports channel technology and object technology, while LEONIS HOLOSOUND supports sound scene technology besides channel and object technology.
