SoundSoap

SoundSoap dramatically reduces tape hiss, buzzing and hum, rumble, and most other types of background noise.

Features:

• SoundSoap's easy & intuitive workspace makes cleaning audio a snap - while its unique Wash Window shows how well it works.
• Removes hiss, hum & buzzing, rumble & most other noise - without harming the audio you wish to preserve.
• Use SoundSoap's one-step Learn Noise button to automatically reduce noise - or use its manual controls for more advanced applications.
• Standalone version works with any QuickTime-compatible audio or video file (AVI, DV, .WAV, SDII, AIFF, MP3, MP4 & many more).
• Preserve Voice button helps remove noise (and other audio) outside of the range of the human voice.
• Hum removal optimized for 60 Hertz (North America, etc.) or 50 Hertz (Europe, Australia, etc.).
• Noise Only mode lets you listen only to the noise being removed - & is ideal for fine-tuning SoundSoap's controls.
