Re: [PD] best way of controlling 50 speakers with pd?

perhaps your speakers already have amplifiers - if not, i came across this link recently for cheap amps:

Hi, Andy and how does your system work? Do you have a link? How many speakers are you using?

I dont need high degree of phase stability , i need to control 50 very cheap speakers. I dont really mind if they dont produce all the frequency range. If each speaker generate only one frequency , its ok.

I only need to be able to control them (the 50) from the computer, i was thinking, maybe not using sound?

    A question to consider; Do the channels need a high degree
    of phase stability?

    Fernando is designing for a WFS system here. You may have more
    relaxed requirements for a theatre or installation
    multichannel
    system not needing such a degree of correlation.
    Using a very simliar approach with jack-udp, but with
    asynchronous receivers, chained ethernet, using gumstick
    or Raspberry Pi boards with cheap audio USB dongles.
