Using this tool is an involved process, but it’s extremely precise and effective. These types of sound are clearly visible in the spectral display and can be selected using a Marquee selection tool, then either attenuated or replaced with similar material from nearby areas. This is particularly useful for removing prominent unwanted noises such as coughs, clunks and clicks from audio files. One of these, the Spectrum Editor, uses Fast Fourier Transform (FFT) to allow the user to peer right inside audio files, and linear-phase filters to execute precise frequency-based edits. While new features in version 6 are less soundbite-friendly, they’re arguably much more useful. The uncompressed PCM audio it supports is in keeping with the format’s base specifications, but doesn’t realise its full potential. This new release retains the one notable exception: the Meridian Lossless Packing (MLP) codec used on commercial DVD-Audio discs to get around the specification’s 9.6Mb/sec bandwidth isn’t included due to its prohibitive cost, so you still can’t generate DVD-Audio discs with six-channel, 24-bit, 96kHz audio. The last version of WaveLab added DVD-Audio authoring to its armoury, offering 5.1 surround sound, 24-bit resolution, sample rates up to 192kHz and accompanying image slide shows.
