Then deselect Output noise only and use Smoothing to 'smooth away' any unwanted artifacts. Select the Output noise only switch to hear the sound being removed and tweak Amount until you just start to hear sounds other than noise, and then back off a little. Smoothing (macOS) - Controls undesirable noises associated with Higher Amount settings.A lower threshold preserves low-level signal details, but can result in noise being modulated by the retained sounds. Select the Output noise only switch to hear the sound being removed and tweak Threshold until you just start to hear sounds other than noise, and then back off a little. Higher threshold settings reduce more noise, but also may suppress low-level desirable components of the signal. Threshold (Windows) - Controls the separation of noise and desirable signal levels.This is not the tool you are looking for. If you need to remove door slams, bird song or any similar transient and variable sound. This background noise can include tape hiss, microphone hum, power mains buzz, camera motor noise, air-conditioning rumble and any other type of noise that doesn't change in level or frequency significantly throughout the recording. The Denoiser is designed to reduce or remove constant background noises in recordings. To activate ensure the Denoiser button is selected. Drag and drop audio files directly on the Envelope editor for automatic analysis. Analyze audio file - Open, analyze and replicate the volume envelope of an input sound file.Create sequence - Opens the Envelope Sequencer tool.Turn all points smooth - Preset filter to quickly filter the envelope.Smooth up abrupt changes - Quick removal of 'spikey' or sudden changes in the envelope.Smooth up - Opens the Smooth Up tool that allows smoothing of the envelope shape (useful in conjunction with Analyze audio file).Filter - Opens the Envelope Filter tool (useful in conjunction with Analyze audio file).Decimate points - Opens a simple tool that allows manipulation of the number of control points in the envelope (useful in conjunction with Analyze audio file).Normalize levels - Scales the envelope so the highest and/or lowest levels reach +/- 100%.
