Repair Audio From the Moments You Cannot Re-record

Find the source that matches your file. Whatever the device or workflow, upload the original damaged file whenever possible.

Interview recordingsInterviews and lectures captured on voice recorders, phone mics, and memo apps often turn unplayable after a failed transfer or card error. One-take recordings cannot be re-recorded — repair them before backing up.

Podcast & music productionInterrupted exports, crashed sessions, or disk errors turn podcast tracks and music stems into WAV / AIFF files that will not open. Rebuilding the file structure is far faster than re-recording an episode.

Camera & field recordingPower loss mid-shot, an ejected card, or a field recorder that stopped unexpectedly leaves location audio with wrong duration or early cut-off. Repairing timing and index data brings the full take back.

Meetings & recovered filesMeeting captures that failed to save, or audio recovered from SD cards, USB drives, and recovery folders, often arrive with broken headers and missing data. Check what is recoverable, then listen to the result.

This software is amazing! I successfully repaired the video files, and the audio is intact as well. I am very satisfied with the results of EaseUS Fixo and highly recommend it to anyone in need of video repair!

Dolf Wijnans

Camera user

I tried other software to repair video files and without success. After I discovered EaseUS Fixo on the website, I repaired the file without any problems. A huge advantage over other software is the preview of a few seconds of the repaired video. Other programs did not offer this option. Now I know why. Because it cannot repair video files.
