Media - Audio Process

Type identifier: media:audio:process Category: Media Operations

Description

The Media - Audio Process node performs audio processing operations on audio files. It supports a variety of operations including speed adjustment, volume normalisation, noise reduction, segment extraction, format conversion, pitch shifting, and fade effects.

Input Handles

Handle	Data Type	Description
`audio`	`file`	The input audio file to process.
`speedFactor`	`number`	(Dynamic) Speed multiplier for speed adjustment.
`targetVolume`	`number`	(Dynamic) Target volume in dB for normalisation.
`startTime`	`number`	(Dynamic) Start time in seconds for segment extraction.
`endTime`	`number`	(Dynamic) End time in seconds for segment extraction.
`outputFormat`	`string`	(Dynamic) Target format for conversion.
`pitchShift`	`number`	(Dynamic) Pitch shift in semitones.
`fadeDuration`	`number`	(Dynamic) Duration for fade effects.

Note: Dynamic input handles appear based on the selected operation.

Output Handles

Handle	Data Type	Description
`audio`	`file`	The processed audio file.
