Looking for a simple audio recorder with built-in playback for foreign language practice. Commandline type okay. Will be using a Skype-type headset with integrated microphone--two separate plugs. Have found many audio recording studio programs, but don't need all that sophistication. Tried a couple, anyway, but neither recognized the mike. And, of course, recorded only silence.
Well, for simple GUI operation, there's gnome-sound-recorder (if it still exists for current releases of Fedora). Though I use audacity if I want to record anything.
Tim,
When I record online audio using audacity, it also records surrounding noise. How do you block it in audacity ?
Few days before I was recording online audio in my laptop. At the same time I was talking with my friend. Audacity recorded that online audio along with my personal talk. I want to record only the online audio, not any surrounding noise. How to do it in audacity ?

This sounds like a mixer problem, and a problem that you'll have to deal with no matter what program you use for recording.
Your sound hardware has more than one potential sound source (microphones, line inputs, CD inputs, etc.), and it's possible to combine them together (mixing), or select to only record from one of them.
Depending on your particular sound card, and the drivers for it, you'll have options for mixing or selecting record sources, and different controls to play with, compared to other cards. Which is one reason why I can't give you a direct answer about how to do it with your hardware.
You'll want to find a controller for your hardware (CLI: alsamixer, Gnome used to have gnome-volume-control, and I don't recall what KDE uses). And look through what options it offers, including the preferences. Look for options about which input will be recorded, mute and turn down mixer controls for things you don't want (e.g. microphone inputs, CD inputs, MODEM audio hardware, etc.).
When it comes to recording sound already being generated by the computer (e.g. radio streams), some sound cards can't do it (my laptop can't, as far as I can tell). Others do it in different ways. You may have an option for capturing the PCM stream, you may have to record the main output from the audio hardware. My desktop PC has lets me record by picking "VOL" as the source.
