faint aftereffect when recording streaming audio

Audacity Help Forum Windows

Using Audacity 2.1 on a new Dell Latitude laptop running Win 7 (all updates installed). I’ve been recording the streaming audio from an internet connection to WGTE to record an all-nite jazz program. WGTE provides a W3Mu app. I set up a timer record using default settings, esp for latency/whatever. BTW, playthrough is disabled, also overdub is disabled. The result is a 4hr .wav file which is exported to an .mp3 file. Upon playback there appears to be a faint second/repeated stream of the same content lagging about a minute behind the primary stream. This is apparent when there is a lull in the main recorded stream … sort of an echo, but not quite. Maybe a latency problem? Can anyone suggest best settings to avoid this? TIA.

One of the ways to record streaming audio is to set up a playback channel and a record channel and connect them together. When you do that, you get all the special effects and processing on both pathways. Your problem sounds a lot like my favorite “cathedral ambience” in the playback pathway.

Which host are you using in Audacity?

I would recommend trying WASAPI with the loopback input selected - that’s what I use to capture internet webcasts, getting good results.

See this page in the Manual: http://manual.audacityteam.org/o/man/device_toolbar.html#host

Yes, am using WASAPI; in fact, “everything” by the Manual. That’s what’s the maddening thing. Thought maybe a reset of the 100, -130 settings might help, but in what direction?

“Latency Correction” is irrelevant if you are not overdubbing. I doubt “Audio to buffer” is anything to do with it either.

In any case “2.1” if that is not a typo or abbreviation is a bogus version of Audacity.

I suggest you install the latest Audacity 2.1.1 from http://audacityteam.org/download/windows. There is a checkbox half way though the installation process to “Reset Preferences”. Put a tick (checkmark) in that box, and say yes to the reset when you launch Audacity.

Can you make a recording of something else online using WASAPI loopback? Assuming you were in bed, you don’t know that the show was playing correctly.
