How We Selected and Ranked These Tools
we evaluated every tool on three sub-dimensions. Features carries a weight of 0.4 because forensic workflows depend on spectral inspection, restoration, batch processing, and feature extraction. Ease of use carries a weight of 0.3 because analyst time matters when spectrogram layers, plugin selections, or command-line pipelines must be executed reliably. Value carries a weight of 0.3 because practical workflows depend on how well the tool delivers repeatable outputs across cases. The overall rating is the weighted average of those three sub-dimensions using overall = 0.40 × features + 0.30 × ease of use + 0.30 × value. Adobe Audition separated itself from lower-ranked tools on the features dimension by combining a spectral frequency display with adjustable time and frequency resolution plus multitrack editing in a single workspace, which supports evidence-grade spectral editing while keeping the workflow in one tool.
