The Waveform Matcher is a REAPER tool that automatically matches similar voice recordings from different media items using peak detection analysis.
Why Use This Tool?
When doing remote voice recording (e.g., via SessionLink), you may work with two versions of the same audio:
- Remote recording - already edited during the recording session but contains artifacts, compression, or quality issues
- Clean local recording - Long uninterrupted voice recording, high quality but unedited recorded locally by the voice actor.
Manually finding and matching each edited segment in the clean recording is very time-consuming. The Waveform Matcher automates this process, saving hours of work.
How It Works
The Waveform Matcher uses a peak pattern matching algorithm that compares characteristics of audio waveforms:
- Peak Detection: The tool identifies prominent amplitude peaks in both the edited and clean recordings.
- Pattern Extraction: For each peak, it analyzes the pattern of surrounding peaks.
- Pattern Matching: The edited peak pattern is compared against every possible position in the clean file.
- Scoring: Matches are scored based on how similar the peak patterns are.
