AB  - This paper presents the methodology and results of a study into the natural variability of the Long Term Average Sorted Spectrum (LTASS) parameter and the relationships between the content, duration and magnitude of an audio recording with such. The results show that both the repeatability and reproducibility are source dependent, and the stability of the parameter decreases as increased variability in the content, duration and magnitude is introduced. The study is a small part of a larger research effort into the use of Likelihood Ratios when evaluating the question of source problem within audio forensics.
