Ratio

A common setting on compressors. This setting relates to a compressors threshold setting. The higher the ratio setting, the more compression will be applied to any audio that breaches the threshold. On lower settings, the compression affect will be more subtle. Ratio settings are also found on gates.

Threshold

A common setting on compressors. This setting sets the threshold for what level the audio signal will kick in, eg if it's set to -15dBFS, this means that the threshold settings will affect any audio that breaches this threshold. On a gate, the threshold setting refers to the point below which the audio cuts off.

DAW

A DAW, which stand for Digital Audio Workstation, is software used for the recording, editing and mixing of digital audio. DAW's started off as integrated hardware units but nowadays, a DAW most commonly refers to recording software.

DAW's follow many conventions from hardware recording set ups. You even have a virtual mixer console and can route audio similarly to hardware set ups. You can also process individual audio tracks using plugins such as EQ, compressors and reverbs.

EQ

EQ, or equalizers, can manipulate the frequency response of audio material in various ways. There are 3 parameters that EQ's typically have, gain, frequency and Q. Gain relates to increasing or decreasing a specific frequency. Frequency relates to which frequency is being manipulated and Q, or bandwidth, relates to how many frequencies around the selected frequency are also affected.

LV2

The LV2 plugin standard is the successor to LADSPA. LV2, which stands for LADSPA version 2, is intended to address the limitations of LADSPA. LV2 plugins can easily be extended and most LV2 plugins come with custom GUI's. Supported hosts include Ardour, Qtractor and Carla. A popular collection of LV2 plugins is the Calf plugin suite.
