NoiseGator ~ Simple Noise Gate

Posted by tom2tec on

Ever wanted to cut out background noise when talking with others on Skype? Now it’s possible!

NoiseGator is a light-weight noise gate application that routes audio through an audio input to an audio output. In real-time the audio level is analysed and if the average level is higher than the threshold the audio bypasses as normal. However, if the average level goes below the threshold, the gate closes and the audio is cut.

When used with a virtual audio cable it can act as a noise gate for a either a sound input(microphone) or sound output(speakers). Can also be used to gate noise from your own mic or play your microphone through your speakers.

REQUIREMENTS:
– Java 7 or higher for Windows.
– Java 6 or higher for Mac. Java 7 recommended.
– A virtual audio cable is required for use with VOIPs:

For Windows users I recommend the VB-Cable driver (http://vb-audio.pagesperso-orange.fr/Cable/index.htm).
Mac users can use SoundFlower.

Features:
  • Noise Gate for audio input to output.
  • Cuts out background noises when nobody is speaking on VOIPs like Skype.
  • Noise Gate your microphone to kill background noise and hiss.
  • Can be used to feed your microphone through your speakers.

LASTAR ~ Batch File Splitting & Normalization

Posted by tom2tec on

LASTAR is a batch (non-interactive) audio processor for loudness adjustment and file splitting of a batch of audio recordings, using an audio transparent maximizer.

At the opposite of usual available software, loudness normalization is done on signal power, which leads to a louder and more homogeneous result than the usual “peak” normalization, in particular on live recordings.

Its purpose is:

  • to split, equalize and normalize digitized analog tapes or vinyl
  • to split, equalize and normalize live recordings from microphones (ex ZOOM H2 recordings)
  • fast and homogeneous normalization of a group of files (compilation for instance)
  • loudness and dynamic reduction for listening in a noisy environment (car…)
  • and so on…

This software aims to be very fast and easy to use : the most efficient computing techniques have been implemented, and there are very few parameters to set (most of them are automatically adjusted by analyzing the file).

It embeds:

  • an automatic RMS normalizer,
  • an Automatic Gain Controller (compressor)
  • a 10 bands automatic equalizer
  • a 3 bands semi-parametric equalizer
  • a file splitter
  • a noise gate
  • preset management
  • a preview function.
