Thanks, I'll look at alsaloop tool. For further info, I am using an I2S sound card (http://www.audioinjector.net/rpi-hat) , and have setup an ALSA device to route playback.pcm through a LADSPA plugin, so all DSP will reside in the plugin, thus I only need to route ALSA input to output in the application 😊 Regards /Robert ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
