It can help reduce common unwanted sounds such as:

• Fan noise
• Air-conditioner noise
• Computer noise
• Microphone hiss
• Electrical hum
• Low-level room noise

What Is an Audio Cleaner?

An audio cleaner is a tool used to reduce unwanted sounds and improve the quality of an audio recording.

Depending on the recording, audio cleanup can involve reducing background noise, hiss, hum and other unwanted sounds while improving speech clarity and overall balance.

An audio cleaner is commonly used for voiceovers, podcasts, interviews, videos, online courses and other spoken recordings.
