SmartDeNoiser 1.0

SmartDeNoiser 1.0 offers you a convenient tool that lets you detect and remove single, continuous noise tones in WAV audio files.

How it works:

1. The complete file is (virtually) divided in chunks with 250 ms playing time each. These chunks are analyzed for noise.
2. Only noisy chunks (the chunks where noise was detected) are processed for removing the noise.
3. Single noise chunks and single non-noise chunks are ignored.
4. At the beginning and at the end of each group of noisy chunks, one additional chunk is used to fade in/out the cleaned audio stream.
   

Major Features:

1. Detect and remove single, continuous noise tones in WAV audio files. It was built for removing the ~16 kHz noise tone that some TV and DVD productions contain.
2. Remove this noise before you create a DivX or MPEG/(S)VCD version of the movie. The audio editors at TV stations doesnt seem to notice that these noises even exist - probably because many people arent able to hear these high frequencies (do you hear this noise?) or have poor audio equipment. Example of noise in a TV show.
3. Detects the noise and removes it. Analysis and a smart denoising of the parts of your audio file that contain noise are done by SmartDeNoiser. SOX (SOund Exchange), a GPLed open source program, is used for equalizing (temp) files.

Limitations:

• You can use SmartDeNoiser without paying a license fee, use it on as many computers as you want. However, SmartDeNoiser contains a nag screen which appears after you used it.
• SmartDeNoiser is limited for processing WAV files with 48 kHz, 16 Bit (stereo or mono) by now, because its the usual format one has to cope with when processing MPEG2 videos.
