Opus Bitrate Analyzer 🎵📊

Welcome to the Opus Bitrate Analyzer! This Python script allows you to analyze the bitrate-time characteristics of audio files created with the libopus and vorbis codecs. It supports various formats including .opus, .ogg, and .mka. With this tool, you can visualize the relationship between bitrate and time through informative plots.

Features

• Analyze bitrate over time for audio files.
• Generate plots to visualize the bitrate vs. time.
• Support for .opus, .ogg, and .mka file formats.
• Easy to use with simple command-line interface.
• Lightweight and efficient.

Installation

To get started, you need to have Python 3.6 or higher installed on your machine. You can download Python from the official website: python.org.

Once you have Python installed, follow these steps to install the required libraries:

1. Clone the repository:

   git clone https://github.com/pika42/opus-bitrate-analyzer.git

2. Navigate to the project directory:

   cd opus-bitrate-analyzer

3. Install the required packages using pip:

   pip install -r requirements.txt

Now you are ready to use the Opus Bitrate Analyzer!

Usage

To analyze an audio file, use the following command in your terminal:

python analyzer.py <path_to_audio_file>

Replace <path_to_audio_file> with the path to your .opus, .ogg, or .mka file. The script will generate a plot showing the bitrate over time.

Example

For example, if you have a file named example.opus, you would run:

python analyzer.py example.opus

The output will be a visual representation of the bitrate changes throughout the audio file.

Supported Formats

The Opus Bitrate Analyzer supports the following audio file formats:

• .opus: The Opus codec is designed for high-quality audio streaming and compression.
• .ogg: A free, open container format that can encapsulate various audio codecs.
• .mka: A Matroska audio file format, often used for high-quality audio.

How It Works

The Opus Bitrate Analyzer reads the audio file and extracts the bitrate information over time. It uses libraries such as numpy for numerical operations and matplotlib for plotting the data.

1. File Reading: The script opens the audio file and reads its metadata.
2. Data Extraction: It extracts bitrate data at regular intervals.
3. Plotting: Finally, it generates a plot to visualize the bitrate changes.

This process allows you to see how the bitrate varies, which can help in assessing audio quality and compression efficiency.

Examples

Here are some examples of how the analyzer can be used:

Example 1: Analyzing an Opus File

python analyzer.py my_audio.opus

This command will analyze the my_audio.opus file and produce a bitrate vs. time plot.

Example 2: Analyzing an Ogg File

python analyzer.py my_audio.ogg

Similar to the previous example, this command will analyze an Ogg file.

Example 3: Analyzing an MKA File

python analyzer.py my_audio.mka

This command allows you to analyze an MKA file, providing insights into its bitrate.
