The MC Audio File Calculator is a WordPress plugin designed to help users estimate the file sizes of MP3 and WAV audio files based on specific parameters. By inputting details such as running time, bit rate, number of channels, sample rate, and bit depth, users can determine the approximate size of their audio files.

Key Features:

  • MP3 File Size Calculation: Users can input the duration (running time) and bit rate of an MP3 file to estimate its size. WordPress
  • WAV File Size Calculation: For WAV files, the calculator considers running time, number of channels (mono or stereo), sample rate (e.g., 44.1 kHz), and bit depth (e.g., 16-bit) to provide an estimated file size. WordPress
  • Integration with WordPress: The plugin allows users to embed these calculators into their website pages using shortcodes:

Understanding Audio File Size Calculation:

The size of an audio file is influenced by several factors:

  1. Bit Rate (for MP3 files): This refers to the amount of data processed per second of audio and is usually measured in kilobits per second (kbps). Higher bit rates generally result in better audio quality but also larger file sizes.
  2. Sample Rate (for WAV files): Measured in Hertz (Hz), the sample rate indicates how many samples of audio are taken per second. Common sample rates include 44.1 kHz (standard for CDs) and 48 kHz. Higher sample rates can capture more detail but increase file size.
  3. Bit Depth (for WAV files): This determines the number of bits used to represent each audio sample. Common bit depths are 16-bit and 24-bit. Higher bit depths provide a greater dynamic range and finer detail but also result in larger files.
  4. Number of Channels: Mono audio has one channel, while stereo has two. More channels (e.g., 5.1 surround sound) increase the file size proportionally.
  5. Duration: Longer audio recordings naturally lead to larger file sizes.

Calculating File Size:

  • MP3 Files: The file size can be estimated using the formula:File Size (in bytes)=Bit Rate (in kbps)×Duration (in seconds)×125\text{File Size (in bytes)} = \text{Bit Rate (in kbps)} \times \text{Duration (in seconds)} \times 125File Size (in bytes)=Bit Rate (in kbps)×Duration (in seconds)×125Note: 1 byte = 8 bits, so 1 kbps = 125 bytes per second.
  • WAV Files: The file size can be calculated using:File Size (in bytes)=Sample Rate×Bit Depth×Number of Channels×Duration (in seconds)\text{File Size (in bytes)} = \text{Sample Rate} \times \text{Bit Depth} \times \text{Number of Channels} \times \text{Duration (in seconds)}File Size (in bytes)=Sample Rate×Bit Depth×Number of Channels×Duration (in seconds)
