Audio Bit Depth Calculator
Calculate dynamic range, quantization levels, bytes per sample, and approximate storage requirements for digital audio.
Estimated Uncompressed Storage—Dynamic Range—Quantization Levels—Bytes / Sample—Data Rate—MB / Minute—GB / Hour—Bit Depth Comparison
Bit Depth Quantization Levels Theoretical Dynamic Range 8-bit 256 ≈ 48.16 dB 16-bit 65,536 ≈ 96.33 dB 24-bit 16,777,216 ≈ 144.49 dB 32-bit 4,294,967,296 ≈ 192.66 dB What does bit depth actually do? Bit depth determines how many possible amplitude values are available for representing each digital audio sample.
Increasing bit depth increases the theoretical dynamic range and reduces quantization noise. This is different from sample rate, which determines how frequently the audio waveform is sampled.
For typical music production, 24-bit recording provides substantially more practical headroom than 16-bit recording during the recording and mixing process.
Important: The dynamic-range figures above are theoretical maximums based on approximately 6.02 dB per bit. Real-world converters have lower usable dynamic range because of analog noise and other hardware limitations.Free audio calculator for musicians, producers, engineers, and home recording studios.
