Well, white noise does only mean that the signal power is equal at any frequency and, yes, it sounds pretty similiar to the radio-in-between sound. It's often used to measure the frequency behaviour of mic's for example. http://upload.wikimedia.org/wikipedia/commons/6/66/Whitenoisesound.ogg Pink noise is another special noise. Punk noise, too. > noticeable at 9-10. But it is not as strong as if a finger is put right > on the unplugged jack. When the sound is similiar to the sound triggered by you touching the unplugged jack it is very possible that its a ground loop noise. Do you use devices that are connected to different electric circuits but the same signalmixer? Otherwise: Try to change the battery or the signal cable. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
