Video demonstrations of algorithm output
- Videos recorded using screen + audio capture while operating a demo GUI implemented for listening and visualizing of the algorithm output
- Videos may be laggy because of screen capture performance issues
Example 1, operation in regular meeting room
Link to video (webM format): A person speaking while moving and stationary loudspeaker playing music.
The 10 second signal is played altogether three times:
- The entire mixture is played once
- Separated source corresponding to speech is activated in the middle
- Separated source corresponding to music is activated in the middle
Example 2, operation in outdoors
Link to video (webM format): A person speaking while moving outdoors, noise from the traffic.
The 10 second signal is played altogether three times:
- The entire mixture is played once
- Separated source corresponding to speech is activated in the middle
- All other sources than speech acticated in the middle
