MP3 Audio Quality Enhancer
Got an old, muffled or noisy MP3? Upload it and get back a cleaned, clarified and remastered version at full 320 kbps quality. Voice memos, lectures, interviews and old recordings all benefit.
Enhance your audio free →What can be restored?
While no tool can invent detail that was never recorded, our chain dramatically improves perceived quality: neural denoising removes hiss and hum, EQ restores presence and air that cheap mics lose, a harmonic exciter regenerates upper harmonics, and loudness normalization fixes weak, quiet files.
Perfect for voice memos and lectures
Phone voice memos and lecture recordings are usually quiet, noisy and dull. The Voice-Over style turns them into clear, even, comfortable listening — great before transcribing, publishing or archiving them.

Frequently asked questions
Can you improve a very low bitrate MP3?
Yes, noticeably. Denoising, EQ and harmonic excitement improve clarity and fullness, though heavily compressed artifacts cannot be fully reversed.
Do you support formats other than MP3?
Yes — WAV, M4A, AAC, OGG and FLAC are all supported up to 50 MB.
Will it work on music recordings?
The chain is tuned for voice. Music may benefit, but vocals and spoken word see the biggest improvement.
Is there a length limit?
Only the 50 MB file size limit — roughly 50 minutes at 128 kbps.
