Im trying to take a guitar tape from a 25W Amplifier with a headset micro. Im running Ubuntu 8.10. Somehow, the recording level is too low, the recorded sound cant be heard. Is there any way to set up the recording level in Ardour?
As far as I know, there is no way to change the actual recording level in Ardour. The only thing you can do in Ardour is boosting the track’s volume or the region gain a little. But that’s not what you want to do when no sound can be heard. Are you sure that Ardour receives an input signal on the track you are recording on?
If it doesn’t, you have to make sure you are using the correct input and the driver is set up correctly. If it does, you should check alsamixer for the recording level. However, you probably want to get an actual microphone and an audio interface with a decent preamp.
Neither Ardour nor JACK attempt to adjust your audio interface’s hardware mixer (if, indeed, it has one). It makes absolutely no sense to change the level in the digital realm - that is just multiplication and it can be done anytime. Only adjusting the analog level makes sense, and this has to be done with the hardware mixer, typically with an application specifically designed for this. For generic hardware, “alsamixer” or “gamix” are options. For specific devices, such as those based on the ice1712/ice1724/envy24 chipsets, there are specific tools (like envy24ctl).
