Per-Type Adapter Hooks

Requirements

Many existing JSON APIs are not consistent between types. As JSON endpoints grew organically and were built by different engineers at different times, the style in which records are represented can vary wildly.

Historically, we have asked adapter authors to rely on the fact that the type of record is provided to all adapter hooks (either by passing a type argument, or by passing a record

About compression

Audio compression is used to reduce the dynamic range of a recording. Dynamic range is the difference between the loudest and softest parts of an audio signal. It was originally used to guard against defects when cutting wax and vinyl phonograph records, but generally became useful as a way of increasing the loudness of an audio recording without achieving distortion.

The goal of most compression applications is to increase the amplitude of the softest parts of a recording, without increasing the amplitude of the loudest parts.

Compressor anatomy

Compressors generally all have the same conceptual parts. However, not all compressors present variable controls for all parts to the user. If you don't see all of your compressor's controls here, there's a chance it either has a fixed value (and no control), or is named something else:
