ADI Virtual
This block is not included in the SigmaStudio installation. Please contact Analog Devices for evaluation and licensing information.
ADI Virtual enhances the stereo soundfield, creating a more spacious listening environment in several styles. It uses sophisticated signal processing to synthesize virtual loudspeakers and give the sensation of being inside the stereo tracks and/or making the music surround you. Built-in spectral shaping filters fine-tune frequency and phase responses. 5.1-channel surround audio (left, right, center, subwoofer, left and right surround channels) can be converted to two-channel format, binaural for headphones and stereo specially treated for loudspeaker playback.
ADI Virtual is intended for lightweight implementation on embedded DSP.
Following are the processing configurations available:
- 5.1 to loudspeakers virtualizer
- 5.1 to headphones virtualizer
- Stereo to loudspeaker virtualizer
- Stereo to headphones virtualizer
- 5.1 mix to stereo
- Stereo passthrough TKTK
Click the appropriate choice to select the input configuration desired.
