Bandwidth limiting is not the issue here (other than if you do enable it on one player in a synch group, MP3 streams are sent to ALL SYNCHED players!). The issue here is that for synched players, the server is only sending ONE stream and that stream WILL be at the lowest common denominator rate that the synched players can handle. Un-synched players are unaffected. I just proved this by sending 24/96 streams to Radio and Touch un-synched. The radio plays 24/48 via a SOX downsampled stream, whereas the Touch gets a 24/96 stream - the display on my TACT shows me this.

Re: [SlimDevices: Audiophiles] Best settings for transcoding?
Only you can answer that, of course, but I hope this may help: Squeezeboxes don't allow FF and RW in ALAC. They do allow it for .wav, .aiff, and .flac. ALAC is therefore not as flexible for SB as .aiff (or the others), although of course it is great for iTunes and iPods, and for keeping storage space down while using lossless files. I therefore myself use .aiff for Squeezeboxes (played through two systems, one purely Quad, one of Quad amps and speakers that I won't mention on an audiophile list!); ALAC for my iPod 4th gen; and AAC at 256kbps for the touch and the nanos, all catalogued in different iTunes libraries . The lossless files are stored on a 1TB external HD, with an ALAC back up on a second one; and the AAC files are on the iMac. System in all is iMac 3.06Ghz running 10.6.2, using iTunes to rip, tag and catalogue, playback using one SB2 and one Classic, and - between the family - iPods 4th gen, Touch and Nano. What ripping/tagging/cataloguing software do you use? That is also a big factor, of course. My suggestion would be that for SB on a Mac you actually go the other way, and change from ALAC and WAV to AIFF. But chacun à son goût, as they say in Hampstead.

Re: [SlimDevices: Audiophiles] Best settings for transcoding?
I'd have to say that the defaults are ideal. You really have to understand what's going on under the hood to change them. So much is dependent on a combination of the OS of the system running the server, the players being streamed to at any given moment, syncing, file bitrates and resampling, that there can't be any blanket recommendation other than leave it the alone. :) The settings page also isn't structured ideally, as there's a lot of logic built into the server itself that isn't represented. Logic that takes into account all of the simultaneous factors listed above. -- JJZolx Jim JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=72703 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Logic that takes into account all of the simultaneous factors listed above. I fully agree. That's why I came here to ask before mucking about and really messing something up. I remember when I set it up originally for the SB2, then SB3, what seems like 5 years ago and it was a bit of a headache. (I think that's how I came across these forums.) Now that I swapped the SB3/DAC out for a TP I wanted to see if the settings I changed held through the years and should be changed/changed back. Thanks all. Unless someone see's something that'd be a sound boon for the TP, I think everything is answered. -- kphinney -I like it, you may not.

Snarlydwarf, Great to hear from you after all these years. Your post brings up a question.

kphinney;496325 Wrote: To paraphrase the unanswered question in the Server forum: Does my S. Server know or have the juice, or bandwidth... actually let's just simplify it and ask: DOES the S. Server stream the best format to all attached devices or just the one that fits all of them? For SB2 and later, it will want to use FLAC for lossless (or something it has to transcode). The SB1 it will use WAV for streaming. The 'capabilities' of the TP and SB2/3/Classic are almost the same, the difference is transporter supports higher sample rates and bit depths (ie, 24/96). In the case of such a file it will transcode the flac to 24/48 for the SB2/3/Classic and leave as-is for the TP. Will a sync'd SB3 and TP receive the same file or, let's assume they are in FLAC, will they both receive a down-sampled version? Hrrm, good question. Someone stole my radio, so can't check right now. (The bad part of bringing the radio to work is they keep stealing it to show off cool networking toys. I should get a commission on sales of the damned thing, but nooo...

Hrrm... simple test: I just set my livingroom player and bedroom to sync. I set the livingroom to be rate limited to 64kbps. that does appear (at least from the webui) to have them both at 64kbps transcoded. So, in the case of syncing, it seems to take the lowest common denominator to keep them synced. -- snarlydwarf snarlydwarf's Profile: http://forums.slimdevices.com/member.php?userid=1179 View this thread: http://forums.slimdevices.com/showthread.php?t=72703 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Best settings for transcoding?
Ah! This may go quite a long way to explain my lack of difference between my TP and my SB3 + DAC. Or if anything the SB3/DAC had a better stage and resolution. I had them sync'd and plugged into Transport and AUX on my amp and clicked between the two. Unfortunately, I'm now back at home and can't give it another go until the weekend when I go back tot he cabin. -- kphinney -I like it, you may not.
