Audio Visualizer | DaVinci Resolve tutorial

In this tutorial, I will show you how to create a reactive audio visualizer in DaVinci Resolve.

DaVinci Resolve hasn't native support to react on audio input. Therefore we need a free third-party plugin.

Suck Less Audio settings:

Wave File - Loads a WAV file. The format has to be WAV (Microsoft) signed 16-bit PCM. If there is interest (perhaps from the Mac side?) I can look into the AIFF structure as well and see if I can manage to add that. MP3 or the likes will never happen ;)

Reload Sample - Reloads the WAV file from disk. Handy when editing audio on-the-fly (thanks ploveday for the tip!)

Select Channel(s) - Will only show when a stereo sample is loaded. Select left, right or both channels as your input

Sample Start Frame - Starts the File Sampling on this frame (so if you want your audio to start at 1001, put 1001 in here)

Mode - how SLA interpolates the samples:

Max: If sample A is +3 and sample B is -4, SLA will return -4 (because 4 is higher than 3)

Unsigned Max: If sample A is +3 and sample B is -4, SLA will return +3 (because +3 is higher than -4)

Min: If sample A is +3 and sample B is -4, SLA will return +3 (because 3 is less than 4)

Unsigned Min: If sample A is +3 and sample B is -4, SLA will return -4 (because -4 is less than +3)

Average: If sample A is +3 and sample B is -4, SLA will return -0.5 (because (3-4)/2 = -0.5)

Unsigned Average: If sample A is +3 and sample B is -4, SLA will return +3.5 (because (3+4)/2 = 3.5)

Median: If sample A is +3, sample B is -4 and sample C is -2, SLA will return sample C (because sorting returns [-4, -2, 3])

Unsigned Median: If sample A is +3, sample B is -4 and sample C is -2,

SLA will return sample A (because sorting returns [2, 3, 4])

Proxy (for sampling) - A 16 bit WAV files contains a LOT of samples. Typically much more than is needed, so it can put unnecessary strain on processing (a 44100Hz stereo sample contains 3675 samples per frame at 24 fps). So the proxy allows for sampling every [value]th frame, so you can have a nice realtime experience enjoying great results :)

Amplitude Scale - Multiplies the result by this factor.

Amplitude Offset - Offsets the result by this value.
Time Scale - Scales the length of the result. So a value of 2 in here will stretch the result over twice as many frames.
