The Panasonic GH4’s audio meters are essential to recording great in-camera audio. You just have to know how to read them.

Panasonic GH4 Audio Meters

The Panasonic GH4 has audio meters. Awesome.

Some of the meters’ blocks even light up red, which probably means something bad. That’s useful.

But what do the rest of the blocks mean? Where is the sweet spot on the meters for your audio? If you’re monitoring with headphones, do the meters even matter?

Yes, yes they do.

Today we’re cracking the code and deciphering the GH4’s audio meters.

Audio Level Range

The GH4’s audio meters represent a range of levels from -30dB to 0dB.

Anything quieter than -30dB and it won’t register on the GH4’s audio meters. This isn’t a problem as you wouldn’t want to record anything important– such as dialog– at such low levels anyway.

Anything louder than 0dB means that the audio is too loud and will result in distortion. Clipped audio is completely unusable, so you should avoid audio that crosses this limit at all costs.

Meters: Block by Block

As audio levels increase, the GH4’s audio meters light up block-by-block from left to right. Here are the levels that each block represents:

  • No Blocks: -30dB and lower
  • Block 1: -30dB to -26dB
  • Block 2: -26dB to -23.5dB
  • Block 3: -23.5dB to -17dB
  • Block 4: -17dB to -14dB
  • Block 5: -14dB to -9dB
  • Block 6: -9dB to -5dB
  • Block 7: -5dB to -1.5dB
  • Block 8: -1.5dB to 0dB

Set Your Target Levels

In general, audio levels should average around -20dB, with peaks at -12dB. This provides a good signal-to-noise ratio, while also maintaining headroom from the clipping limit.

Using the GH4’s audio meters, target block 4 for general audio. -20dB falls within block 3 on the meters, but levels in this block could also result in lower levels than desired, so targeting block 4 is recommended for most situations.

Average levels at Block 4

Furthermore, audio peaks should not exceed block 5.

Finally, activate the GH4’s limiter for an additional layer of protection against clipped audio in the event of unexpectedly loud sounds.
