Basic Sound Recording Signal Chain

 

Dynamic Condenser
More robust Louder, more sensitive
No need for external power supply (phantom) Need phantom power (batteries or external power supply)
For shorter distances: <6″ (15cm) For longer distances
Handle bigger sound pressure: percussive sounds, loud sources React to quicker incoming signal
Usually cause less feedback (but depends on pickup pattern); good for live situation Higher attack

Pickup patterns

 

ZOOM RECORDER:

  • It’s a good idea to filter out low frequencies to reduce noise (a safe setting is at around 80 Hz)
    • MENU —> INPUT —> LO CUT
  • NOT recommended to use compressor limiter on this recorder, although it’s useful on other devices.
  • Turn “MONO MIX” off. If you’re using one mic, you should only have sound in one ear (one channel). Otherwise, if you hear it in both channels (and you’re not using two mics), you’re getting noise from the other, unused channel. Later, you can grab each channel individually in editing.
    • GENERAL RULE —> Separate sources as much as you can, it gives you more control later
  • A good range is to keep the peaks between -20 and -12
  • Record to WAV, and compress later
    • REC —> REC SETTING —> REC FORMAT

 

Sample Rate Bit Depth
How often recording is taking a sample from the stream, related to sound quality (like image resolution How many levels of differentiation
Greater sample rate, the more accurately the contours of the curve are represented At each instance, how much information is processed
