Squeezebox Touch: jitter thru wi-fi?

No.

Jitter only comes into play during the analog to digital conversion process which occurs all within the squeezebox using the internal DAC or between squeezebox and external DAC if external dac is used.

The only issue wit Wifi comes if teh bandwidth is not sufficient to provide data to the Squeezebox fast enough to convert in real time. The result is temporary delays in the playback until the Squeezebox receives enough data to proceed converting to sound in real time.

Wifi bandwidth is affected by noise/interference on specific channels, physical obstacles in the path of teh transmission between remote devices and router, and physical distance between router and remote devices.

Mapman - I noticed a few second delay with my Airport Express. I think they fill the buffer to prevent drop-outs in case of interference. Jitter-wise AE was tested by Stereophile and measured word jitter on digital output was respectable 250ps.

Kijanki, yes, buffering helps reduce dropouts however I believe if throughput between server and Squeezebox client goes too low, the buffer still might not be filled fast enough to keep music flowing. That is what I experience on occasion with similar Roku Soundbridge product, and would expect similar with any network player device.

Mapman, I have dropouts sometimes (once a week) - much better now since I found microwave oven frequency in its manual and changed wireless channel away from it. Ideal would be to switch to 802.11n (5GHz) but my MacMini doesn't support it.

Yes, I have had occasional dropout issues with wireless G as well and found changing router frequency can help.

With the default frequency/channel configured in my router for wireless G, I found that my Rokus would loose their connection to the server temporarily whenever our wireless phones rang for an incoming call. The wireless phones were apparently interfering on that frequency. Changing router channel configuration solved that problem.

Hadn't considered microwaves. Next time I get a delay, I will have to check to see if the microwave upstairs is in use......
