The root or purpose of all mods is to make the operating system and/or the music software run to maximum efficiency. The lines of code are already installed no need to do them over again, in fact if you open the rcS file again you will see them at the bottom.

Re: [SlimDevices: Audiophiles] I need a little bit tone control . . .
I walked through some manuals, it shouldn't be so difficult. But it looks like Inguz tools are not developed anymore since a tweak is necessary to get it to work under windows 7? Anyway, if I have installed it and it, how do I create a filter curve with +2dB at 150Hz? The measuring programs create a curve/wav, but how do I do this manual? I have to say after reading I got exited about room correction and it's benefits so I would probably take the long route in time an buy a microphone and do the whole setup. But for now, how do I create a filter manually? Can one of the programs do that? I also looked at Sox, but I don't know if that is that simple I looked at the file 'convert.conf' but it is quite a study to understand it.

Re: [SlimDevices: Audiophiles] I need a little bit tone control . . .
Hi Bert003, the entries in convert.conf do not mean that every thing is converted. They are only rules which will be applied if you want conversion to be applied. This is what you select in the Advanced/File Types menu. The standard selections do not do any conversion if it is not necessary, e.g. because your player does not understand a music format. Daverz gave a nice line as a starting point. As long as you stay with simple changes sox is easy to use. Doing a real room correction might also be possible, but that might be more complicated than Inguz. -- frank_from_hh frank_from_hh's Profile: http://forums.slimdevices.com/member.php?userid=25866 View this thread: http://forums.slimdevices.com/showthread.php?t=89355 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

What I am after is info on whether the Linn DS SPDIF output is that much better (or at all better) than that of a modded SBT ... Anyone? The problem here is that such a test is only valid for one particular DAC. There is such large variability in S/PDIF input circuits that if you determine which sounds better with one DAC, there is guaranteed to be other DACs where the reverse is true. The input impedance of receiver circuits varies all over the place (not very many are even close to the official 75 ohm spec). The impedance match between the source and receiver is one of the important aspects of sound quality. A particular source does have a particular jitter and noise signature on its output, AND a particular output impedance. Both the jitter/noise AND the impedance match are important contributors to sound quality for many DACS. The jitter/noise are going to be constant with different DACs, but the impedance match is going to be a crapshoot. The result of this is that say you have a DAC with a 90ohm input impedance and you fed it from a source which has close to 90ohms output impedance, its going to sound better than another source which has lower jitter but has 75ohms output impedance. This makes the whole concept of determining the absolute quality of a source to be almost ludicrous. If you take several sources and rank them with different DACs from different manufacturers the ranking order is going to be different, guaranteed. An interesting aspect of this is that because the final result is primarily a combination of the two factors, if you take some sources and significantly improve jitter/noise performance on all of them, the impedance matching is now going to be the predominant factor, so the variability in ranking between them is only going to get worse. So as engineers and tweakers figure out how to improve the jitter/noise performance of the sources, figuring out which one to choose for your system is going to be even more of a crapshoot. That does not mean that things like TT2.0 are worthless, far from it. For a given DAC (say the one YOU have) making these tweaks can improve the final results, because they are improving one of the two main components. If your particular situation has a good impedance match between the source and receiver then such tweaks may make a big improvement. If your situation has a lousy impedance match then the tweaks my be less effective. Again its hard to tell in advance. So I guess what I'm trying to say is that trying to make a determination as to which source is better only makes sense if you specify a particular DAC.

Re: [SlimDevices: Audiophiles] New Squeezebox Touch Mod
Just a caution, the process numbers are not carved in stone, as you comment or uncomment things in rcS or change hardware configuration (such as running off a USB disk), some of those process numbers can change. So I highly recommend running the command ps -eLo pid,cls,rtprio,pri,nice,cmd | grep -i irq as listed in the instructions to find out what process numbers are used for a particular interrupt on YOUR system. Use those process numbers in your modified rcS file. The IRQ numbers for a particular device seem to stay constant no matter what, but the process numbers do change if you change the system. From one boot to the next with a particular system configuration the the process numbers DO stay the same. Just remember that if you change your hardware configuration there is a very good chance some of those process numbers will have to change in the rcS file.

Re: [SlimDevices: Audiophiles] New Squeezebox Touch Mod
Hi alec, For the purpose of audio I was only interested in audio related processes. Again these are tweaks I previously used on my Linux machines. They proved to make Music Player Daemon sound really well so I just used them on the Touch. For the Touch it would appear that the etho IRQ would be important however I was not able to isolate that process. Also because the server does some work with the audio 'bits' I applied the same tweaks [and more] to the Linux server as well. However I have been building a cMP2 machine to use as the Squeezebox server just to see if it makes a difference.
