Music Glossary G Terms


This is the name given to the amplification of a signal level. It can be expressed as a ratio of the output signal amplitude to the input signal amplitude.

For example:

Gain = Vout / Vin

Gain is normally expressed in dB.

For Voltage Gain use:

Gain (dB) = 20 log10 Vout/Vin

For Current Gain use:

Gain (dB) = 20 log10 Iout/Iin

For Power Gain use:

Gain (dB) = 10 log10 Vout/Vin

Gain Control

This is a device that adjusts the gain of an amplifier. This is normally done by altering the amount of negative feedback in the amplifying system. A Gain Control is not the same as an ‘attenuator’ or a ‘volume’ control.


A fold-out vinyl album sleeve is also used for some Digipack CD cases. Typically Gatefold sleeves either open like a book or fold out into three sections.

Glass Master

A glass master is used during the CD replication process. It is created by the replicator, based on the submitted mastered recording, as a master for the purpose of pressing CDs. It is a one-off cost added to the price of the first order of a CD run with a replicator. Subsequent runs use the glass master created as a result of the first run order.

Gold Album/Gold Single

In the USA, the RIAA certifies an album or single as gold when it sells 500,000 units. In the world of downloads and streaming, the digital transmission of 10 individual tracks by an artist counts as one album.

Many world territories have different sales thresholds for “gold.”. See for a full list of music recording certifications.
