How many inputs?
• How many elements do you want to record simultaneously to discrete tracks? If for example, you wanted to record two acoustic guitars and a voice at the same time onto separate tracks, you will need some sort of sound interface which features at least three inputs. • If you wanted to, you could theoretically record an entire orchestra to a single track using an interface with only one audio input. But what you would loose with a set-up of this type is the ability to process individually the recording you had made of each element. • Typically, it is preferable to have the recording of each instrument on it’s own track so that you can make adjustments afterward. You might for example, want to remove the lower frequencies from the vocal track, pan the guitar fully to the left of the stereo field and add some reverb to second guitar. If these were all mixed together on one track, any alterations you carried out, post recording, would have to be performed globally on all of the instruments
