Game Audio North #GANtalks – 8th April 2017
- Convolution is the process of multiplying each sample of an input audio signal with each sample of an impulse response, which acts as a complex filter.
- Sources such as voice and piano have pink distribution of frequencies.
Relatively Static (won’t capture randomness)
Dynamic Limitations (won’t change harmonic content)
- Transient Recording
Popping balloon, hand claps etc.
Ideally needs broadband response
Captures the frequency of the mic, and object or speaker
Spike/Impulse (maximum amplitude at infinite frequencies)
Useful (only) for capturing digital gear
- White Noise Sweep
Lower signal-to-noise ratio
Altiverb Sweeps (requires deconvolution)
Not equal loudness
Starting click to align
Useful for capturing analogue gear
