Clean Up Phone Call Recording Audio
Remove background noise, narrowband codec artifacts, and environmental sounds from recorded phone calls — free AI tool
Phone call recordings muffled, noisy, or unclear due to connection quality, background noise, or the inherent limitations of phone audio codecs?
Traditional phone calls compress audio to a narrow frequency band (300Hz–3.4kHz) for transmission efficiency — the resulting recordings sound thin and distant before any background noise is added. Voice Isolate removes the background noise (traffic, HVAC, home ambient) that layered on top of the already-compressed phone audio, maximizing clarity within the phone call's inherent frequency limitations. Works on recordings from any call recording app or platform.
What You Get:
- Remove caller-side background noise: car traffic, home ambient, outdoor sounds, office noise
- Works on TapeACall, Rev Voice Recorder, ACR Call Recorder, Google Voice, and all call recording app exports
- Maximizes intelligibility within phone audio's inherent 300Hz–3.4kHz frequency range
- Accepts MP3, M4A, and MP4 recording exports directly from any platform
