Screen recordings
Drop the recording here. Solipsium checks the voice for fan noise, hum and clipping before it changes anything, and leaves the picture alone.
Drop a screen recording here
Solipsium checks it in your browser for clipping, hum and noise, without uploading it. It can then repair the first 20 seconds for you to hear, with no account.
MP4, MOV, MKV, WebM, WAV, MP3 and more, up to five minutes for the check.
After signing up, drop the same file into the editor to repair all of it.
Then drop the same file into the editor. Scans and short repairs are free.
Finding the file
Each tool asks whether to record the microphone. If it did not, there is no voice to repair.
Shift, Command and 5 opens the screen recording controls; their Options menu chooses the microphone and the folder the recording is saved to.
The Snipping Tool records the screen, and the Xbox Game Bar records a game or an app. Game Bar recordings go to the Captures folder inside Videos.
A screen recorder that runs in the browser lets you download the video; drop that file here.
Fault by fault
The check reads the recording's sound in your browser. The try repairs the first 20 seconds on Solipsium's server.
A laptop working hard spins its fan up. A steady floor within 26 dB of the voice gets Full-band speech cleanup, a speech model that keeps the voice's full range and lowers what surrounds it. The result reads: “A steady noise floor was found, so it is removed.”
A laptop charging from the mains can add hum, notched out: “Mains hum was found, so it is notched out before any cleanup.”
Keystrokes are short sounds the try leaves. Remove keyboard noise says what the editor can turn down.
Echo reduction runs only when echo is the one thing found, with no steady noise, music, hum, clipping or muffled sound beside it. On a longer recording it works about 20 seconds at a time. The result reads: “Room echo seems to blur the speech, so echo reduction is used.”
Questions
No. With a free account, the editor repairs the sound while you watch the picture in sync, and a video export keeps the original picture with the repaired track.
Solipsium's free try is built for speech, and its cleanup may remove music and other sounds along with the noise. The editor's note reads: “Targets hiss in speech. Check quiet or distant voices; may remove music and ambience.”
WebM files open in Chrome, Edge, Firefox and Safari. WebM to MP4 converts one for apps that want an MP4.
The editor takes videos of up to 30 minutes and 1 GB. Cut a longer one with the video trimmer.
Not for the check, which runs in your browser. Pressing Repair the first 20 seconds sends those 20 seconds; when your browser could not open the file, or it runs over five minutes, the file itself goes to Solipsium's server, so the try is offered for it only up to 25 MB. Solipsium keeps only the first 20 seconds and deletes them within an hour. If you are signed in, a file you drop or choose is uploaded to your account and opens in the editor instead. The privacy notice has the rest.
