This folder contains a series of codes used to verify the implementation of a particular sound quality metric. The verification of the following metrics is provided:
- Loudness according to ISO 532-1 [1]
- Sharpness according to DIN 45692 [2]
- Roughness model from Daniel & Weber [3]
- Fluctuation strength model from Osses et al. [4]
- Tonality model from Aures [5]
- Effective Perceived Noise Level (EPNL) [6]
