IIEQ ~ Parametric 10-band Equalizer


The IIEQ is a free, fully parametric 10-band equalizer with its own, characteristic sound and low CPU consumption. The 1st and the 10th band are low and high shelf filters, respectively; all other bands are peak filters. Individual bands can be switched on and off (click on the small green buttons!). It is available for Windows (32/64 bit) and Mac (32 bit). Alternative GUIs are available for Windows 32bit only.

SmallEQ ~ Tiny 10 Band Equalization


Sick and tired of huge GUIs taking up all screen space? Want an EQ that easily fits in your pocket but sounds just like the big guys? Then it’s time to meet SmallEQ! The world’s smallest 10-band EQ, sporting eight fully parametric bands plus one low- and one high-shelf filter on exactly 9135 square pixels. Controls from left to right: band choice, gain, frequency, width and overall gain.

NoiseGator ~ Simple Noise Gate


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.

HA Forum Topic

Linear phase is a property of a filter, where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. And consequently, there is no phase distortion due to the time delay of frequencies relative to one another.
