media-sound/jack is an old CD ripping application, so this is not what you want. |
12 |
|
13 |
media-sound/jack2 is the C++ coded jack daemon for multi-processor PCs. |
14 |
|
15 |
media-sound/jack-audio-connection-kit is (I think) the jack1 daemon coded in C. |
16 |
|

For Jack1 Vs Jack2 features have a look here: |

For streaming websites which do not offer a download button, you can |
34 |
launch the browser developer tab, select Network/Media and keep an eye |
35 |
on the traffic as you click on the website to start streaming the |
36 |
video. The developer tab will list the actual path of the video file. |
37 |
Open another tab in the browser and paste the full URL to download it, |
38 |
or you could try curl/wget et al. |
39 |
|

tee-ing the audio output of desktop applications/windows may be doable |
41 |
with dmix and asoundrc syntax, but I wouldn't know what this looks |
42 |
like today with any certainty - last time I used dmix was in the mid |
43 |
00s. Anyway, you tried this and it didn't work. |
44 |
|
45 |
Jackd was created for the very purpose of plumbing I/O audio into |
46 |
various configurations, so tweaking it to do the recording you require |
47 |
should be eminently doable and using one of the various Gtk/Qt front |
48 |
ends makes it even easier/quicker. |
