Learn Noise, that samples the noise you want to remove.When it comes to noise reduction, I’m quite impressed with SoundSoap. NOTE: For filmmakers, because we often want to keep the sound of the location, it is a better idea to look for ways to reduce the noise, rather than remove it. It is impossible to expect that any application could get rid of every noise. It is best described as “all the sounds you don’t want.” This could encompass air conditioners, a baby crying, a siren, crowd noise… anything. I could not hear any degradation in the speaker’s voice as the clicks were removed. As the clip was playing, I dragged the Declick slider until the clicks disappeared. In all cases, clicks are a sudden, sharp sound that stand out from the rest of the audio. There are lots of different clicks, from cleaning up an old vinyl record to removing lip clicks from narration. This was very nicely handled and the audio difference was striking. The bottom waveform shows the dynamic range that was restored. The top waveform shows clipping as flat tops in the waveform. #SOUNDSOAP REVIEW PRO#NOTE: Neither Final Cut nor Premiere Pro provide audio tools to fix clipping. “Clipping is a form of audio distortion that occurs when the signal is overdriven beyond it’s maximum volume range, and reduces the sound quality and intelligibility of material.” (SoundSoup User Guide) The benefit is simplicity, the disadvantage is that there are no audio meters to show you the results of your changes. I found this setting very easy to use, though I would prefer audio meters so I be more precise in my adjustments, and the results were as pleasing as any other compressor/limiter I’ve played with. (In audio terms, this acts as a compressor/limiter.) The benefit to using SoundSoap is that it will be faster than booting into your video editing system, boosting volume does not cause distortion and the batch processing mode (described below) can fix all the clips contained in a single folder. SoundSoap can improve audio levels using their “Boost Volume” setting. I always prefer saving a new copy “just in case” I need to go back to the original for any reason. NOTE: You have the option of replacing the existing file or saving a new copy. To save a cleaned-up copy of that file, choose File > Save As, select a format (for audio-only, I would recommend either WAV or AIFF), pick a name and location and save the file.
