Re: [linux-audio-dev] mp3 fft with python

For my college final project, I'm embarking on a very similar idea. My project advisor has me implementing a wavelet transform in python, and displaying a waterfall in tcl/tk. GRanted, I've never programmed in either language; I'm not even sure either of those are efficient enough to handle it

Quoting Steve Harris [EMAIL PROTECTED]: I disagree, its not the wrong model - the master node (with the audio i/o) run a normal jack driver, and all the slave nodes run a network jack driver that read/writes from the network. Yes, I believe this is the way to do it. Has anybody played with

I'd really suggest considering the pros of integrating IETF tools (SIP, RTSP, RTP) into this scheme. You could use still use jack as your application later, but instead of engineering your own transport layers for session management (SIP, RTSP) and media (RTP), you'd use IETF protocols -- just

- the system needs every period to be the same size (unless you are not running in real-time or the remote load is *very* low, but then what is the point?). thats potentially a bit ugly, but in practice, its probably going to work, especially with JACK-driven clients/hosts. - The system
