Recorded a voice-over, interview or talking-head video near a fan or air conditioner? Reduce steady background noise from its audio track and download a clean WAV for editing or publishing.
Choose a file, keep the defaults or adjust the options, then click the main button. The finished file downloads automatically when it is ready.
Upload the video, audio or GIF from your device. Its name and preview appear immediately so you can confirm the selection.
The defaults are ready to use. Change any visible format, quality or size options only when you want a different result.
Click Convert, Compress, Normalise or Make GIF. The finished file downloads automatically when it is ready.
Simple tools, clear results, no unnecessary steps
Upload the recording you already have. The tool reads the audio track and returns a cleaned WAV.
It works best on steady fan noise, air-conditioning hum, microphone hiss and consistent room tone behind speech.
The result is a 48 kHz WAV, avoiding another lossy encoding pass after noise reduction.
Download the complete converted file in the format you chose, with no preview-only result or watermark.
Open the tool on a phone or computer and get started. No app or extension is required.
Conversion is free with a signed-in Spira account. There is no per-file charge and no length ceiling hidden behind a paywall.
Use it when speech is understandable but a constant background sound makes the recording feel rough. Podcasts, voice-overs, interviews, tutorials and talking-head videos with one steady noise source are good candidates.
Denoising cannot reliably separate two people speaking at once, remove music underneath a voice or repair clipping and distortion. Sudden sounds such as knocks, keyboard taps or traffic horns may also remain because they are not steady noise.
It is designed for steady sounds such as fan noise, air-conditioning hum, microphone hiss and consistent room tone.
Yes. Upload an audio or video recording and the tool will process its audio track. The download is an audio-only WAV file.
No. It cannot cleanly separate overlapping voices or music from the speaker you want to keep. It is intended for constant background noise.
A 48 kHz WAV avoids adding compression artifacts after noise reduction and is easy to edit, sync back to video or convert later.
Spira AI takes a script or a link and produces a finished short with voiceover, visuals and captions, then publishes it on a schedule. These tools are the bits you reach for along the way.
