But Ghidra was released at around the same time as I was interested in the inner workings of the DSP plugin, so it seemed rude not to give it a try. I'm not sure that I'd repeat the exercise. :) I have attached an 'octave' script that captures my calculations and notes on methodology, etc. It might be useful to have in the tool box. Run by 'sourcing' it. It's worth being aware that the TI codec chip has DSP capabilities that are not being used. DSP coefficients can be set by way of an Alsa control. I haven't tinkered with it, and I suspect (unverified) that its quality may not match that of the DSP plugin. I have had in mind a project to use it to add a bit of bass cut to quell some of the "baritone boom" inherent in speech. Perhaps I'll look at that again, now that I have refreshed my memory on DSP processing. +-------------------------------------------------------------------+ |Filename: SB_Radio_DSP_filters.m.txt | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=29606| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ mrw's Profile: http://forums.slimdevices.com/member.php?userid=38299 View this thread: http://forums.slimdevices.com/showthread.php?t=111663 _______________________________________________ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
