Snapshot Testing for Audio DSP - A Picture's Worth a 1000 Tests

This 16-minute conference talk from the Audio Developer Conference (ADC 2024) explores snapshot testing as an innovative approach for testing audio DSP algorithms. Learn how traditional testing methods often struggle with describing complex audio outputs, leading many developers to rely on manual testing. Discover how snapshot testing offers an elegant, automated alternative by using audio waveforms to verify DSP algorithm results, making code refactoring safer and more efficient. Speaker Josip Cavar, an experienced programmer with over a decade of experience who has recently specialized in audio development, shares practical insights on implementing this testing technique. The presentation includes downloadable slides for reference and is part of ADC's mission to help audio developers acquire new skills and build professional networks in the field of audio development technology.
