⚡ HOW TO CALCULATE UNCOMPRESSED AUDIO FILE SIZE ⚡

Calculating raw audio file size depends on four core Variables:

• 🎚️ Sample Rate (kHz) — 44.1kHz, 48kHz, 96kHz
• 🎛️ Bit Depth — 16-bit, 24-bit, 32-bit Float
• 🔊 Channels — Mono vs. Stereo
• ⏱️ Duration — Track length in minutes & seconds

Whether you’re exporting a master bounce from your DAW or archiving multi-track recordings, calculating file size prevents disk storage issues & upload bottlenecks!

📐 The Standard Formula (PCM WAV / AIFF):

File Size (Bytes) = Sample Rate (Hz) × (Bit Depth / 8) × Channels × Duration (Seconds)

💾 WAV vs. MP3: THE ULTIMATE COMPARISON 💾

• 📁 UNCOMPRESSED AUDIO (WAV / AIFF):
  • 👑 CD Quality (16-Bit / 44.1kHz): ~10.1 MB per minute
  • 🚀 Studio Master (24-Bit / 48kHz): ~16.4 MB per minute
  • ✨ Preserves 100% audio fidelity & dynamic range. Ideal for mixing, mastering & studio archives.
• 📦 COMPRESSED AUDIO (MP3 / AAC):
  • ⚡ 320 kbps (High Quality): ~2.4 MB per minute (~80% smaller than WAV!)
  • 📻 128 kbps (Web Standard): ~0.95 MB per minute
  • 📉 Lossy compression discards imperceptible frequencies to save bandwidth for streaming & mobile devices.

🔥 PRO TIP FOR PRODUCERS: Always keep your original mixdowns in 24-bit / 48kHz WAV format before rendering MP3s for web release or distribution!
