Recording & transcription

Import audio and video to transcribe

Bring in existing recordings, from MP3 to MP4, and get a transcript.

Updated 2026-06-14

You do not have to record inside Echo Chamber to transcribe with it. Import audio or video files you already have and turn them into searchable text on your device.

Common formats are supported, including MP3, WAV, M4A, AAC, MP4, and MOV, so a voice memo, a downloaded recording, or a video file all work.

Clean up noisy source audio

A recording with clear speech produces a cleaner transcript. Audio enhancement, with noise reduction and normalization, can help tame steady background sound in noisier files.
