Reduce Noise with Noise Reduction Tools
Noise in audio, recording, and broadcast systems refers to the residual low level sounds (usually hiss and hum) that is heard in quiet periods. In audio engineering it can refer either to the acoustic noise from loudspeakers, or to the unwanted residual electronic noise signal that gives rise to acoustic noise heard as "hiss".
All sound recordings can suffer from faults, though modern recording practice minimizes most of them to the point where they aren't a problem. However in the restoration of old (mostly analogue) recordings there are a number of faults which are normal in recordings: the restoration process involves trying to eliminate or at least reduce them. MP3 Editor for Free provides noise reduction tools to get rid of annoying hiss, hums, clicks, rustles, chirps, shuffles and creaks.
Follow the lead to reduce noise with noise reduction tools:
To add the noise reduction effect, you firstly need to launch MP3 Editor for Free and add an audio file to the waveform window. Then click "Noise Reduction" tab and choose "Noise Reduction" to specify detailed parameters or apply some popular presets to adjust the effect. Click "Preview" to listen to the music before adding the effects to the waveform to make sure you get exactly what you want. Click "OK" to add the noise reduction effect to the selected region (You can also select "Cassette Noise Reduction" or "Voice Breath Noise Reduction" to reduce the noise).
