I'm using inguz's plugin on Windows, which he was kind enough to send me. It isn't publically available yet, as far as I know - I'm a kind of beta tester. However if you've got slimserver set up on Linux and you're willing to mess around a bit you can probably get things working using brutefir - you just need to add a line to convert.conf or slimserver-convert.conf that tells it to pipe WAV (or whatever) to brutefir with the appropriate options. At least I think that will work - I haven't actually done it, since it seems no convolver which accepts stdin and stout is available for Windows (except the one inguz wrote). Another option is to use foobar (with the convolver plugin) to convolve with the filter and then just play the resulting file with slimserver. That's a bit less convenient but works perfectly well. To make the filter in the first place, download DRC. All the tools you'll need are there, although the documentation takes a while to wade through. The procedure is as follows: make a log sweep file using glsweep (part of the DRC package). record it using a mic - the best thing is to play a stereo track of the sweep, with both channels identical, and record one speaker with the mic on one channel and the other output of the SB looped back into the mic pre-amp as the other channel. Now do the same for the other speaker. run lsconv (another DRC utility) on the recorded files, using the looped back channel as the reference file. run DRC on each file - start with the normal.drc config file, modified to point to the impulse you made in the previous step. Now combine the two files into a stereo WAV file (using sox or audacity or something else), making sure not to mix up the channels, and use it with brutefir or foobar convolve or some other convolver. It's somewhat complicated... although once you get a good recording of the sweeps that part's over, at least until you get new speakers or re-arrange your room. Anyway, let me know if you want to try it and something in there is unclear. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=25598 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
