right, it might sound a bit complicated but here goes...
i need to record from a low audio quality mono-source for like 7 hours...
in that 7 hours i need to be able to push a button and have 10 sec before the button push and 20 sec after with the same button to be able to be pushed and time reset to finish 20 sec after the last press...
now, i need a way to have the audio seperated somehow when that button is pushed, like saved as a seperate audio file or same file but recorded on other audio channel as a stereo file perhaps...
now the 7 hour recording is not 100% needed but would be nice to have, the audio before and after the button push is what is needed.
i know i will need a usb audio dongle for mic/line input.....
what can be done? whats the simplest thing.... at the moment i been using a dictaphone but its really hard to find moments in that recording that is needed even with audio software
