Choose the right tool
These tools operate on audio samples in a WAV container. They preserve the sample rate and let you target a specific editing task. Analysis reports signal measurements; editing produces a new PCM WAV file you can preview and download.
- Inspect the recording first to see channels, duration, peak level and DC offset.
- Use peak normalization to adjust maximum amplitude; it does not measure or normalize perceived LUFS loudness.
- Join files only when sample rates and channel counts match. Output strips metadata and does not resample or dither.
