Introduction

AcousticMetrics.jl is a Julia package for computing various metrics useful in acoustics. Currently implemented metrics include:

• Various narrowband spectra

  • Pressure amplitude
  • Mean-squared pressure amplitude (MSP)
  • Power Spectral Density (PSD)
  • Phase

• Proportional band spectra

  • Approximate octave and third-octave spectra
  • Exact proportional spectra of any octave fraction integer > 0.
  • Lazy representations of proportional band spectra constructed from either narrowband or proportional band spectra

• Integrated metrics

  • Unweighted and A-weighted Overall Sound Pressure Level (OASPL)
