1. What is the Uncompressed Audio File Size Formula?

The formula S = (SR × BD × CH × D) / 8 calculates the file size of uncompressed audio in bytes. It takes into account the sample rate, bit depth, number of channels, and duration of the audio.

2. How Does the Calculator Work?

The calculator uses the uncompressed audio file size formula:

Where:

• \( S \) — File size (bytes)
• \( SR \) — Sample rate (Hz)
• \( BD \) — Bit depth (bits)
• \( CH \) — Number of channels
• \( D \) — Duration (seconds)

Explanation: The formula calculates the total number of bits (SR × BD × CH × D) and converts it to bytes by dividing by 8.

3. Importance of Audio File Size Calculation

Details: Calculating audio file size is important for storage planning, bandwidth requirements, and understanding the quality implications of different audio formats.

4. Using the Calculator

Tips: Enter sample rate in Hz, bit depth in bits, number of channels, and duration in seconds. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 8 in the formula?
A: We divide by 8 to convert from bits to bytes, since there are 8 bits in 1 byte.

Q2: What are typical values for sample rate and bit depth?
A: Common values include 44.1kHz/16-bit (CD quality), 48kHz/24-bit (studio quality), and 96kHz/24-bit (high-resolution audio).

Q3: How does compression affect file size?
A: Compression algorithms (like MP3, AAC) can significantly reduce file size while maintaining perceived audio quality, often by 75-90%.

Q4: What's the difference between mono and stereo file sizes?
A: Stereo (2 channels) files are approximately twice the size of mono (1 channel) files with the same duration and quality settings.

Q5: How can I convert bytes to more practical units?
A: Divide bytes by 1024 for kilobytes (KB), by 1,048,576 for megabytes (MB), or by 1,073,741,824 for gigabytes (GB).
