Quick calculations for acoustics, recording, timing and system setup. Results are calculated in your browser and nothing is submitted.
Estimate free-field sound-pressure level at a new distance from a point source.
Uses the inverse-square free-field relationship. Reflections, boundaries, source directivity and line-source behavior can change real-world results.
Convert frequency to wavelength using air temperature to estimate the speed of sound.
Useful for room acoustics, loudspeaker spacing, microphone placement and understanding low-frequency dimensions.
Estimate uncompressed PCM audio storage for multitrack sessions.
This is raw PCM data only; DAW project files, edits, backups, alternate takes and file-system overhead require additional space.
Convert acoustic path distance to arrival-time delay and digital samples.
Useful for loudspeaker alignment, acoustic timing estimates and translating path-length differences into DAW delay values.
Convert decibels to voltage/amplitude ratio or power ratio.
Amplitude ratios use 20 log10; power ratios use 10 log10. Negative dB values produce ratios below 1.
Calculate the first five axial modes for a rectangular room.
These are axial modes only. Tangential/oblique modes, construction, openings and damping also affect low-frequency behavior.
Convert an acoustic path-length difference into delay and phase shift at a chosen frequency.
Useful when estimating comb-filtering risk from spaced microphones or unequal acoustic paths.
Estimate how long an audio session or archive will take to upload or download.
Actual transfer time varies with protocol overhead, server limits, congestion, Wi-Fi conditions and storage performance.
