Why Resound?

88% acceptance rate

88 out of 100 suggested edits are accepted (cut out) by users.

200,000+ examples

Filler sound detection has been trained on thousands of real podcast audio files.

16,000 data points in 1 second of audio

That's why our edits have precisely accurate start and end times.

Trained on audio data, not text

This means far more accurate edits than traditional solutions like STT APIs.
Your message is our mission.

Empower, not replace

Resound is built by the same team of professional audio engineers behind Culpable and 15 other #1 shows on Apple Podcasts. We know from experience how tedious and time consuming post-production can be. Resound was built from the ground up to automate the mundane so you can focus on your message, not your mess-ups.
