Greetings, GoldWave also has the ability to move key without changing pitch, move up or down a tone, or semi-tone, keep tempo the same works fairly well but none of these algorythms are perfect, there is always a compromise, but GoldWave is not free once the trial expires.

Colin Howard, who, by the Lord's providence has lived at his present address near Fareham in Southern England, since February 1992 and though Southern England, including parts of Hampshire suffer floods from this current stormy weather, because living about 200 feet above sea level, no problems so far and hopes not to move in the near future.
