"crackling" distortion - davbarnert@aol.com - 12-04-2020
I have been using JamKazam for several months. Whenever I play in a session, the others describe a "crackling" distortion in my audio output. I do not hear it in my earbuds. Latency has not been a problem. My setup is:
MacBook (Retina, 12-inch, Early 2015) plugged in
MacOS Big Sur Version 11.01
Sterling Audio SL230MP Matched Pair mics
Earbuds
FocusRite Scarlett 2i2 audio interface
HyperDrive HD30F USB-C Hub
Ethernet cable -> Synology RT2600ac router -> D-Link DSL-520B ADSL2+ modem
(Would plug directly into modem, but it only has one output socket and I’d rather not unplug router)
Verizon DSL internet service
I am playing a concertina: https://youtu.be/wqwDnMXrY9Q
Other internet devices in airplane mode during JamKazam sessions.
Any suggestions/help would be appreciated. Note, fiberoptic internet service is not available in my area and I have heard that cable internet service has deteriorated.
Thank you.

I am new here - and I have the same -- it seems to be random and not tied to either volume or timeframe.. Every 2 min or so I'll get like 10 seconds of crackling - it's not clipping - that's a different sound entirely . hope someone here has a cllue!

RE: "crackling" distortion - Guitarzan38 - 01-21-2022
Hey there. Silver member here since last year. I, too, am experiencing significant "crackling". I do not hear it while playing, but it is apparently quite steady to those I play with. One of them recorded it (link below) so I could hear it and use it as an example. I have tried changing my frame size and it seems to behave the same.
Hope this link works...

Also, this is my path...
Guitar->
pedal board ->
RNP8380 Preamp->
XR18->
2014 MacBook Pro (Running Catalina) ->
Jamkazaam
using an XR18 amp modeler for a bit of break up.
Any suggestions from you JK gurus?
RE: "crackling" distortion - Zlartibartfast - 01-22-2022
it sounds like either a high amount of jitter (variations in network throughput - shows up as long/short ping times) which is a network performance issue,
or an audio buffer running out (not enough memory allocated in the audio stream) which is often an audio driver issue.
Is this a new problem (was it working before without issues)?
