Yes I am using EZcap as that's the only cassette transport I have with a digital/USB output. Father Christmas brought it a couple of years back and I've never got round to using it before. As it's low mileage as compared with the analogue kit I have, the reproduction is a million times better. It comes up in Audacity preferences as "USB PnP Audio Device: Audio (hw:1,0)" whatever that means. But Audacity doesn't control it; I have to press the buttons to make it start/ stop etc.
In my first post I said I'd found a way to do the recording in Xubuntu but that meant reducing quality.
Since the software build on the Xubuntu partition is the same as those on the other m/cs I used audacity v2.1.2 with the same preferences including the 48000 Hz default project rate that solved the recording skips issue. Sadly the recording would not proceed beyond 1 minute, stopping after anything from a few seconds to around 50secs. Fiddling about a bit I've found that it will run OK if in the Quality Preferences I set Default sample format = 16-bit and High-quality conversion: Sample rate converter = Medium Quality. The results appear to be OK as the quality of the source cassettes leaves a lot to be desired.
However as my objective is to get rid of boxes and boxes of old cassettes, I'd like to digitise them as faithfully as possible so reducing quality is a last resort.
When I analysed the WinXP recordings I found a lot of extraneous noise that doesn't appear on recordings made with the big PC (XPS17) so as I'm not inclined to spend time faffing with windows, I've put the video editing on hold and started to do the Audacity recording on the big PC. However, out of interest (and possibly for future reference) I am interested in anything that would make Audacity more efficient when running on *ubuntu, or Linux in general.
I could go out and splash a load of cash on some new hardware but ... ... I return to my original question:
Why is WinXP better at running Audacity than Xubuntu?
