Peak Tracer

Peak Tracer is a command-line tool that helps you find the loudest parts of an audio file and export them as JSON or concatenate them into a new file.

Requirements

Peak Tracer requires FFmpeg to be installed on your system.

Installation

To install Peak Tracer, you need to have Go installed on your system. Then, run the following command:

go get -u github.com/Paxx-RnD/peak-tracer

This will download the source code and build the binary for you. You should now be able to run the peak-tracer command in your terminal.

Usage

Peak Tracer can be used with the following command line options:

Parameters

  -i string
        The path to the input audio file (required)
  -o string
        The path to the output JSON file (required)
  -after float
        The number of seconds after each peak to include (default 1)
  -before float
        The number of seconds before each peak to include (default 1)
  -concat string
        The path to the output file for concatenation
  -samples int
        The number of samples per peak (default 48000)
  -target int
        The target duration of the output file in seconds (default 60)

Finding peaks

To find the peaks in a media file, you can use the following command:

peak-tracer -i input.mp3 -o output.json

This will analyze the input file and export the peaks as a JSON file.

Concatenating peaks

To concatenate the loudest parts of a media file into a new file, you can use the following command:

peak-tracer -i input.mp3 -concat output.mp3

This will analyze the input file and create a new file that contains the concatenated peaks.

Customizing the behavior

You can customize the behavior of Peak Tracer with the following options:

-after: The number of seconds after each peak to include (default: 1).
-before: The number of seconds before each peak to include (default: 1).
-samples: The number of samples per peak (default: 48000).
-target: The target duration of the output file in seconds (default: 60).
