# Standard Identifiers

To support some out-of-the-box analyses provided by Intelie, a set of common identifiers must be configured.

When those fields are configured, some macros are enabled to support the access to that specific mnemonics. For example, when configured, `@@channels.bit_depth` will refer to the bit depth mnemonic, whatever it is, in any environment.
