Summary: I'm interested in capturing audio through a microphone and, in real time, determining which frequency range (from a set range of frequencies) has the maximum level. This would be used to determine which note is loudest out three notes.
More info: Hello! I was hoping to get some direction for a project I'm working on. I'm also searching the mailing list archives, but I apologize in advance if I ask questions that have been answered elsewhere. If you think my question has already been answered, I would appreciate any advice on how to better search the archives to find what I'm looking for.
I am creating a staged adaptation of a 'Choose Your Own Adventure' novel. For more information, check out the Wikipedia article at http://en.wikipedia.org/wiki/Choose_your_own_adventure The important thing to know is there will be a branching storyline, decided by audience voting.
For the voting, I plan for everyone in the audience to have a small xylophone with 3. Each note will correspond to a voting choice presented by the cast. I'm going to have microphones positioned around the theatre to capture the xylophones and pipe them to a computer. What I'd then like to do through PD is determine which note was 'loudest,' meaning the most people cast it for their vote.
The voting choices will be displayed by a projector connected to the computer running PD. Thus, I'm interested in either piping the level information to another program (PowerPoint or something else) to display which vote won. I'd also be interested in doing this directly through PD, if it's possible.
I'm working my way through the PD tutorials included in the program itself, but would appreciate any advice or suggestions on keywords I can use to search the archives.
Please let me know if there is any information I can add to make things more clear. Thanks in advance for all your help. -Jared
