Select a real sample file you are allowed to process. Begin with a short, simple input before attempting a complex document or recording.
What to inspect in the output
Listen to voice pitch as well as duration. Resampling couples speed and pitch, so this is unsuitable when natural-sounding pitch preservation is required.
Where this tool stops
Resampling changes both speed and pitch.
