To remove background noise, load your audio file into WavePad.
- On the Effects tab, click the Cleanup button and select Noise Reduction, Audio Spectral Subtraction. Click the preset drop-menu and select voice or music, then click OK to apply.
- Then again from the Effects tab, click the Cleanup button and select Noise Reduction, Multi-band noise gating. Select a preset, then click OK to apply.
If the presets aren't giving you the best results, try using lower levels on each type of reduction until you find a combination that leaves you with just the audio that you want to hear. Download WavePad audio editing software today to try the noise reduction feature for yourself.
