Yes. You can enhance a 60-second preview of any file for free, without an account. A free Chord account comes with 20 AI credits, enough to enhance up to 90 minutes of audio.
What files can I upload?
Audio and video files: MP3, WAV and MP4. With an account you can enhance files up to 2 hours long and 1 GB.
What does the enhancer fix?
It reduces background noise and room echo and makes voices clearer and more present, so your recording sounds like it was made in a studio.
Can I enhance the audio in a video?
Yes. Upload an MP4 and Chord enhances its audio. With an account you can download the full video with the new audio, or just the audio as an MP3.
Which preset should I choose?
Start with Balanced. Use Natural Clean when your recording is already good, and Studio Voice to get studio-quality sound, even from noisy places or laptop and phone microphones.
