SPDIF EQ

Started by Dirk Bruere at NeoPax January 26, 2010
Does anyone do a s/w 3rd octave equalizer that will work on a stereo 
(non dolby etc) SPDIF output (from a mobo or soundcard)?

Not a comp.dsp question (unless you want someone to design and build it for you, for the appropriate high fee). Use an audio gear forum somewhere. "Google is your friend" (most of the time). Most digital graphic EQs (and Room Correction systems) above seriously cheap low-budget models have SPDIF interfaces. Richard Dobson

I'm asking here because I cannot get an answer on audio NGs. And I am looking for a PC based *software* solution, not a DSP board. Does comp.dsp have room for questions concerning DSP s/w on PCs? -- Dirk http://www.transcendence.me.uk/ - Transcendence UK http://www.theconsensus.org/ - A UK political party http://www.blogtalkradio.com/onetribe - Occult Talk Show

I just did a Google search for "pc software 1/3 octave eq" and got a ton of hits. Many of them download for free. Greg

This is a technical/engineering list (the "comp" is a bit of a clue) - dsp maths, algorithms, some hardware design. Only a minority are especially concerned with audio. They talk more about comms, radar, filter design, etc. Try the musicdsp list for a list dedicated to audio dsp. It is an almost totally vague and undefined question. If you had problems on an audio NG you will have even more here! Your question implies that you want to use one PC to process an SPDIF signal input from some other machine. And presumably output it through the SPDIF output of the same card. There is any amount of free and commercial audio software on PCs etc that will one way or another enable audio input from a soundcard (e.g. SPDIF input) to be processed through plugins etc, and out again. Bound to be a graphic equaliser plugin somewhere; more if you are prepared to spend money. Can't think of one offhand, I don't use such things. You haven't even mentioned what OS you are running. Vista? Linux? Since you didn't answer to it, I will ~assume~ you are not trying to equalize output from a PC etc prior to sending to the speakers; which is the most common reason to want to process an SPDIF output from one machine on a second one. Some people do even do that with PCs, e.g. using FOSS software on a Linux box. I suggest you try the audio NGs again, but form your question ~much~ more precisely. Satte the task you are trying to perform,as clearly as possible, not what you assume the solution might be. Oh, and even a DSP board actually runs software. Different kind of chip (probably), but software is software. And if you really do want to connect the SPDIF output of a computer to some some second machine, the hardware DSP box will likely be both cheaper and better. Richard Dobson

If the question relates to filtering algorithms, this is probably the best place. That is true independent of the implementation. Discussions on DSP hardware also do pretty well, though as far as I understand it the title, comp.dsp, refers to signal processING, not processORS. (Both commonly called DSP.) Analog signal processing questions usually do pretty well, and maybe analog interfacing, too. SPDIF doesn't seem to be discussed much, though. -- glen

Sure. Sometimes it takes a bit od convincing that the besy platform for a pet task is in fact a PC with a sound card.
