What Aulio Studio repairs
Three families of damage ruin most speech recordings. Aulio Studio fixes all three in one pass.
Constant noise
Electrical hum, hiss, air conditioning, fans, fridge drone, steady traffic. The noise floor under everything.
Fix: Broadband noise removal strips the entire noise floor while preserving the voice.
Sudden sounds
Dogs barking, birds, car horns, keyboard clicks, door slams. One-off noises that noise gates cannot catch.
Fix: Transient elimination detects and removes one-off sounds without clipping the speech around them.
Broken speech flow
Filler words, stutters, long dead-air pauses, and levels that jump between too quiet and too loud.
Fix: Filler and stutter removal, silence trimming, and loudness normalization to broadcast standards.
Repair a recording in four steps
Drop in the damaged file
Audio (WAV, MP3, M4A, FLAC, AIFF) or video (MP4, MOV). Phone memos, Zoom exports, old interviews, anything with speech.
Choose what to repair
Noise removal, transient elimination, filler and stutter cutting, silence trimming, loudness target. Enable only what you need.
Compare before and after
A/B the original and repaired audio side by side, loudness-matched, so you can verify the repair before committing.
Export the repaired file
MP3, WAV, M4A, FLAC, or AIFF, up to 192 kHz. Every job is kept in history so you can re-export later.
A 30-minute recording repairs in under 3 minutes on Apple Silicon.
When do you need a full restoration suite instead?
Professional spectral editors like iZotope RX exist for surgical work: repairing clipped waveforms, restoring damaged music, editing individual harmonics. They are powerful, priced accordingly, and take time to learn. Aulio Studio covers the other 95% of real-world repair jobs: spoken-word recordings that are noisy, unclear, or uneven.
✅ Aulio Studio is right when
The recording is speech, the voice is audible, and the problem is noise, clarity, fillers, or loudness. You want it fixed in minutes, not an afternoon.
🎛️ A spectral suite is right when
The audio is clipped or distorted, it is music rather than speech, or you need manual frequency-level editing for forensic or archival work.

Audio repair FAQ
Can Aulio Studio fix audio recorded on a phone or laptop mic?
Yes. Phone and laptop recordings are the most common repair jobs: they pick up room noise, hum, and handling sounds. Aulio Studio removes the noise floor and rebuilds voice clarity so the recording sounds like it came from a proper mic.
Can it repair old interview or lecture recordings?
Yes, as long as the speech itself is audible. Constant noise like tape hiss, hum, and ventilation is removed, and loudness is normalized so quiet historical recordings become comfortable to listen to.
Can it fix clipped or badly distorted audio?
Honest answer: no. Aulio Studio repairs noisy, unclear, or uneven speech recordings. Severely clipped or distorted audio needs a specialized spectral restoration suite. If the voice is intact under the noise, Aulio Studio will recover it.
Does repairing the audio change how the voice sounds?
No. The neural models separate speech from noise instead of filtering frequencies blindly, so the voice keeps its natural character. You can compare original and repaired versions side by side before exporting.
Can I repair many files at once?
Yes. Drop a whole folder of recordings and Aulio Studio processes them all with shared settings. A 30-minute file takes under 3 minutes on Apple Silicon.
