Dataset Checker and Audio Analyzer

Review the original recordings

Use the Dataset Checker to locate possible clipping, long pauses, unreadable files and inconsistent active levels. Listen to flagged ranges before editing. Preserve intentional pauses and quiet delivery when they belong to the intended voice.

Inspect the cause

Use the Audio Analyzer to compare waveform peaks, spectrum, pitch and levels. A flattened peak can indicate clipping. A persistent spectral band during silence can point to hum. Compare suspected problems on the original and the conversion before deciding which stage to change.
