[Discuss-gnuradio] Throttle block form wav files

Hi,

I'm using a flow graph with no GUI to demodulate a signal. I have a selector block that allows me to select the source of the signal between the audio card and a wav file. I can change the source using an xmlrpc server/client.

If I don't use a throttle block with the wav file, the flow graph takes all the CPU and the server/client is very slow.

If I put a throttle, I get audio underruns when using the audio card. Same problem for a constant source.

Can anyone please recommend a better way to do this?

Cheers,

Murray
