Use this music calculation for a precise timing, pitch, tuning, MIDI, dynamics, or audio-engineering conversion under a stated tempo and reference convention.

Amplitude Ratio

Required number input.

Amplitude gain in decibels from a positive output/input amplitude ratio. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Gain Decibels (dB)

The resulting gain decibels returned as a number.

• Results depend on tuning reference, temperament, note naming, tempo map, meter, MIDI implementation, sample rate, level reference, weighting, and artistic performance. Equal temperament and ideal timing are not universal musical requirements.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the reference pitch and timing grid explicit, verify against the target instrument or DAW, and use listening tests for perceptual decisions.

• Bit Depth Dynamic Range Db

  Ideal full-scale sine-wave quantization signal-to-noise ratio in dB, approximately 6.02N+1.76 for N-bit PCM.

• Crest Factor Peak To Rms Db

  Crest factor in dB from positive peak and RMS amplitudes.

• Dbfs To Linear Amplitude

  Linear full-scale amplitude ratio from a signed dBFS level, using 20 log10 amplitude.
