CleanSpeech Audacity chain

Many years ago, there used to be a "CleanSpeech" chain available in Audacity.

The chain was as follows:

    1. StereoToMono

    2. Normalize

    3. SaveHqMaster

    4. NoiseRemoval

    5. TruncateSilence

    6. Leveller (this can be replaced with a compressor instead)

    7. Normalize

    8. ExportMp3
