Frequently Asked Questions
Audio Ducking is a technique where the level of one audio signal (music) is reduced by the presence of another signal (voice). This is commonly used in radio and podcasts to make speech clearer.
WAV is an uncompressed format, meaning it preserves 100% of the audio quality. Use WAV if you plan to edit the file further. Use MP3 if you need a smaller file size for sharing.
Since this tool runs entirely in your browser, your device's processor is doing the mixing and encoding. Large files (like hour-long podcasts) take a moment to process. Please wait for the progress bar to finish.
