What creators say
“I record in my living room. Before Sondra, every episode had fan noise. Now it sounds like I have a studio.”
— Alex M., Podcast Host
“Compressed a 400MB iPhone video to 60MB in under a minute. Uploaded to YouTube immediately. No quality difference I could see.”
— Sophie T., YouTube Creator
“Cleaned up a 45-minute Zoom recording before sending to a client. They asked what mic I was using.”
— Marcus R., Freelance Consultant
