Turning how audio sounds into decisions you can measure.
Amplify Consultants helps audio and technology teams evaluate sound quality with rigorous listening tests, connect those results to objective and AI-based metrics, and set clear targets products have to meet.

Perceptual evaluation
Blind listening tests (MUSHRA, BS.1116, ABX, MOS) designed so the results hold up and actually answer your question.
Audio quality + AI
Which objective and AI-based metrics track what listeners hear, where they break down, and how to use them safely.
Targets & standards
Turning "it should sound great" into measurable targets, acceptance criteria, and release tests your teams can use.
Can AI metrics stand in for listeners?
I benchmarked 34 audio quality metrics, 17 of them AI-based, against expert MUSHRA listener ratings. A machine-learning fusion model reached a correlation of 0.89 on unseen trials, compared with 0.74 for the best single metric. The limits are documented too.
Correlation with expert listener ratings (unseen trials)
Pearson r. Higher means the score tracks what listeners actually rated.
Have a product that needs to sound right?
Or a team that needs a perceptual audio lead? Either way, let's talk.
