How to decide how many channels you need for a recording
While it depends on what type of group you're recording, typically you use one channel for each musician/instrument/group of instruments in your ensemble. Each channel you record takes a single source of audio from a single mic and sends that audio to the recording device. Take a look below to see some examples.
Example 1, a small choral concert.
- Channel 1: Piano
- Channel 2: Choir
- Channel 3: Soloist
- Channel 4: Director (if there are introductions to each piece)
Example 2, a garage band.
- Channel 1: Vocalist
- Channel 2: Background Vocalist
- Channel 3: Lead Guitar
- Channel 4: Rhythm Guitar
- Channel 5: Bass
- Channel 6: Kick Drum
- Channel 7: Drum overhead
Example 3, an orchestra concert.
- Channel 1: Stage right mic
- Channel 2: Stage left mic
- Channel 3: Percussion mic
Example 4, a school debate/presentation.
- Channel 1: Event host
- Channel 2: Team 1 mic
- Channel 3: Team 2 mic
- Channel 4: Audience participation mic
The important thing to keep in mind is that each event is different and only you know exactly what type of setup, instruments, and mics you'll be using. The examples above are just general suggestions to point you in the right direction.
