I went through those steps again, started a new session, new unnamed file, hit the red record button, then just let it ride awhile, as I was busy with some other things. I wanted to see if it picked up anything at all. The meter at the extreme bottom left corner, showed that it was running, but I can't tell from it how big it is, or indeed if anything at all is happening. (In Audacious, by contrast, you can see when it's picking up sound, as there is visual output that show spikes, peaks and valleys, clipping, and so on. But all I ever saw with krec was that thin purplish line. After I let it run for maybe 45 minutes, I ended up with a krec file of 782.4 kb, which again didn't seem like much. When I opened that file in a new instance of krec, it showed a raw file that looks much bigger (that is, a bigger raw image). Now if I could make some changes in krec's configuration, then I might be able work better with it, as I could see if there is any progress. By the way, I have nothing against doing things the hard way, if it yields results, if I get something that is stable and usable, that I don't have to keep resetting or reconfiguring; once I have my settings right, I want to be able to make a few clicks, or run a command, and it always behaves as I choose, without ugly surprises. Then, I got the bright idea to export it as a wav file, to make it easier to process with Audacity, to increase volume or whatever. Surprise! krec took a very long time, maybe another 45 minutes, to process that file, which I watched getting bigger and bigger. When at last it was finished, I had a wav file of 785.8 mb. Now that's that's an amazing file compression ratio. However, it still replays no sound at all, just a flat line. It may be that I have to mess around a bit more with the host. That is, in alsamixer or kmix, I have to choose the Logitech USB microphone, then change settings until I pick up sound. At the moment, krec works, it just doesn't actually record anything. Bill
