short impulses and display filter

[mikoga]

Hi! Thanks a lot for a great product and for all the answers in the forum! we use a raspberry with matrix voice and have 2 questions:

1. While testing, we noticed that it does recognize the direction of sound source with continous sound (such as talking). however, if we clapped hands or knocked on objects, it wasn't recognized.. so we guess the question is how to configure odas to recognize short impulses?
2. In SST module, how to make odas display to terminal only data that the 'activity' parameter is bigger than 0? (besides a script that filters it after displaying... if it can be configured in config file that'd be great!) Thanks in advance!

Hi!

1. ODAS can localize short sounds like clap, but the tracking system usually removes short time events to avoid false detection when we want to track speech sources only. To have ODAS detect short time sound events, try to set this parameter in the SST section to this value:

N_prob = 1;

2. For now we always display all "slots" of the tracking results. Like you said you can have a script to filter, or you can also change the function snk_tracks_process_format_text_json, and add a condition to print only the active sources. I'll keep in mind your suggestion to have a parameter to display only active sources!

Best,
