How this service works
Dynamic range, levels and smallest step for a PCM bit depth, theoretical SNR, and the bit depth needed for a dB range.
Output
Returns a JSON object with: number of quantization levels, dynamic range in dB, dB per bit, LSB size in dBFS and optionally in volts, signed min/max integer values, theoretical SNR for a full-scale sine wave, and (if dB range was the input) the exact and rounded-up bit depth needed. Also includes a summary string and any disclaimers.
Example use cases
Verify bit depth for recording project
“I'm setting up a studio recording session and want to know the theoretical SNR and dynamic range I'd get with 32-bit float — can you calculate the bit depth specs including the number of levels and dB per bit?”
Find minimum bit depth for broadcast spec
“Our broadcast spec requires at least 120 dB of dynamic range — how many bits of PCM do I need, and what's the exact fractional answer before rounding up?”
Calculate LSB voltage for ADC design
“I'm designing an ADC with a 3.3V full-scale peak voltage using 16-bit PCM — what's the LSB size in volts and dBFS, and what dynamic range will I get?”
Technical details
Endpoint
GEThttps://audio-calc.x402tookit.com/bit-depth?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, formula-based PCM audio bit depth calculations — dynamic range, SNR, quantization levels, LSB step size, or required bit depth for a given dB target. It is purpose-built for audio engineering and digital audio workstation (DAW) contexts, returning all standard metrics in a single call. Prefer it over general-purpose math tools when the domain is specifically PCM audio bit depth.
Side effects
- Missing both 'bits' and 'dynamicRangeDb' parameters — endpoint needs at least one
- Bit depth out of range (must be 1–64) — returns error or empty result
- Non-integer value supplied for 'bits' parameter
- Network or payment failure (x402 payment required at $0.02 USDC per call)
