# [plh] Module Configuration

The `plh` module reads and writes audio feature files.

## Input and Output

Mode | Input | Output | Description
--- | --- | --- | ---
`READ` |  | `nf` | Reads in the normalized feature frames from file, outputting them to the `nf` stream.
`WRITE` | `nf` |  | Accepts normalized frames on the input stream, and writes them to a feature frame file.

Examples:

    nf <- plh(READ, input)

    output <- plh(WRITE, nf)

## Parameters

Some of these parameters do not have an internal default value. You must either set the configuration parameter to a suitable value, or set the value in the corresponding action parameter.
