12 Services from audio-calc.x402tookit.com

Converts a frequency ratio or cent value to cents, semitones, and octaves, names the just/Pythagorean interval, and optionally applies the interval to a base frequency in Hz.

Returns frequencies, cents, and ratios for all 12 chromatic notes in equal, 5-limit just, Pythagorean, or quarter-comma meantone tuning, relative to a specified root and A4 reference pitch.

Calculates audio file size from bitrate and duration, solves for missing bitrate or duration given file size, and computes PCM file size from sample rate, bit depth, and channels.

Converts audio buffer size (in samples) to one-way and round-trip latency in milliseconds at a given sample rate, or finds the buffer size needed to meet a latency target.

Calculates the combined, averaged, or background-corrected sound level in dB from multiple sources or identical sources.

Converts between linear amplitude and dBFS, and computes RMS level, crest factor, and headroom for sine, square, triangle, or sawtooth waveforms.

Calculates loudness gain adjustments to hit a LUFS target or streaming platform standard, predicts true peak after gain, and combines segment loudness values.

Calculates the Nyquist frequency for a given sample rate, plus optional tone aliasing analysis (alias frequency, samples per cycle, below-Nyquist status) and the guard band above 20 kHz.

Calculates dynamic range, quantization levels, LSB step size, theoretical SNR, and required bit depth for a given PCM bit depth or dB range

Calculates axial, tangential, and oblique room mode frequencies for a rectangular room, plus the Schroeder frequency derived from RT60.

Calculates speed of sound, wavelength, period, and delay-per-metre for audio frequencies at a given air temperature, with bidirectional frequency/wavelength/delay/distance conversions.

Calculates sound pressure level at a new distance or finds the distance for a target dB level using the inverse-square law (6 dB per doubling for point sources, 3 dB per doubling for line sources).
