Audio Bitrate Calculator (Uncompressed PCM & Compressed Audio)
Calculate audio streaming bitrate and file sizes across sample rates, bit depths, and audio formats.
TL;DR: Audio Bitrate Calculator computes uncompressed PCM audio bitrates (sample rate × bit depth × channels) and estimates file sizes for WAV, AIFF, FLAC, MP3, and AAC audio tracks.
How Do You Calculate Uncompressed Audio Bitrate and File Size?
Uncompressed Audio Bitrate (kbps) = Sample Rate (Hz) × Bit Depth (bits) × Channels / 1,000. For standard CD audio (44,100 Hz, 16-bit, 2-channel Stereo): Bitrate = 44,100 × 16 × 2 / 1,000 = 1,411.2 kbps. File Size = Bitrate (kbps) × Duration (s) / 8,000 (~10.58 MB per minute).
How to Use the Audio Bitrate Calculator
Our Audio Bitrate Calculator performs high-precision mathematical operations directly in your browser with zero latency and complete client-side privacy.
- Select audio format: Uncompressed PCM (WAV/AIFF), Lossless (FLAC), or Lossy (MP3/AAC/OGG).
- For uncompressed audio, choose Sample Rate (44.1 kHz, 48 kHz, 96 kHz, 192 kHz) and Bit Depth (16-bit, 24-bit, 32-bit float).
- Select number of audio channels (Mono = 1, Stereo = 2, 5.1 Surround = 6).
- Enter audio track duration in minutes and seconds.
- Review the calculated total file size in MB and streaming transmission bandwidth.
100% Client-Side Privacy Guarantee
All calculations run locally inside your browser using JavaScript and client math engines. Your numbers, dates, values, and financial records are never transmitted to or stored on external servers.
Frequently Asked Questions
- Standard CD-quality audio is uncompressed 44.1 kHz, 16-bit stereo, producing a constant bitrate of `1,411.2 kbps`.
- A 5-minute 44.1kHz/16-bit stereo WAV file is approximately `52.9 MB` (or `86.4 MB` at 48kHz/24-bit studio quality).
- A 5-minute MP3 encoded at maximum 320 kbps quality is approximately `12.0 MB` (`320 kbps × 300 s / 8,000`).
- 16-bit audio provides 96 dB of dynamic range (65,536 discrete amplitude levels), while 24-bit audio provides 144 dB of dynamic range (16,777,216 levels), eliminating digital noise floor during audio recording.
- 48 kHz (48,000 samples per second) at 24-bit depth is the universal broadcast and cinema video standard.
