Music Calculators
Last updated: October 2026
Loop Length Calculator
Convert a musical loop length in bars into its duration in seconds at any tempo.
Chord Frequency Analyzer
Find the exact frequency of any note in a chord given a root pitch, chord type, inversion, and octave.
Compressor Ratio Calculator
Determine the output level of a dynamics compressor given an input level, threshold, and ratio.
Audio File Size & Bitrate Calculator
Calculate the uncompressed or compressed file size of an audio recording in megabytes.
Stereo Width Calculator
Calculate the stereo width ratio from mid-side (M/S) processing using mid and side channel gain values in dB.
Guitar String Tension Calculator
Calculate the tension in pounds for a guitar string based on scale length, gauge, target pitch, and material.
Frequency to Note Calculator
Converts any audio frequency in Hz to its closest musical note and MIDI number, with support for custom tuning standards.
Frequency to Pitch Calculator
Convert any audio frequency in Hz to its position in cents relative to a reference pitch (default A4 = 440 Hz).
Chord Interval Calculator
Calculates the interval in semitones between any two MIDI notes, collapsed to a single octave.
Scale Degree Calculator
Finds the MIDI note number for any scale degree within a major or natural minor scale, given a root note.
Metronome Subdivision Calculator
Calculate the precise pulse rate of any rhythmic subdivision or polyrhythm at a given tempo in BPM.
Studio Acoustic Calculator
Estimate the reverberation time (RT60) of a recording studio or rehearsal room using its dimensions and surface absorption.
Sample Rate & Bit Depth Calculator
Calculate the uncompressed file size in megabytes for any combination of sample rate, bit depth, channel count, and duration.
Flanger Feedback Calculator
Calculate the resonance boost in dB produced by a flanger's feedback circuit from a given feedback coefficient.
Band EQ Frequency Calculator
Compute how far a bell, high-pass, low-pass or shelf EQ band reaches from its centre frequency, given Q and gain.
Song Length Calculator
Calculates the total duration of a song in seconds from its number of bars, time signature, and tempo.
Audio Delay Time Calculator
Calculates delay times in milliseconds that sync perfectly to a song's tempo, for any note division from whole notes to 32nd notes.
MIDI Velocity Calculator
Convert a MIDI velocity value (0β127) to its equivalent level in decibels.
Musical Frequency Ratio Calculator
Convert semitone intervals into target frequencies and explore how tuning systems affect pitch relationships.
MIDI Velocity Curve Calculator
Map raw MIDI note velocity (0β127) to a shaped output velocity using curve types like linear, exponential, or soft.
Cents Tuning Calculator
Measures the pitch interval between two frequencies in cents, the standard unit for fine tuning.
Phaser Rate Calculator
Sync your phaser's LFO to your track's tempo by converting BPM and cycles-per-bar into a precise rate in Hz.
MIDI Velocity Dynamics Calculator
Transform raw MIDI velocity values using linear, soft, or hard curves to shape how dynamically expressive a performance feels.
Vinyl RPM Pitch Calculator
Calculate the percentage pitch change when a vinyl record plays at a speed different from its original RPM.
Gate Threshold Calculator
Calculate the optimal noise gate threshold in dB by finding a level 30% of the way between your noise floor and your signal level.
Room Acoustics & Standing Wave Calculator
Identify the lowest standing wave (room mode) frequency in a rectangular room to spot bass buildup problems.
Guitar Fret Distance Calculator
Calculates the exact distance from the nut to each fret on a guitar from the scale length, using the equal-temperament rule.
Audio Crossfade Calculator
Compute the ideal crossfade duration in seconds for DJ mixes or audio edits based on BPM, transition style, and fade curve.
LUFS Loudness Calculator
Calculate how many dB of gain your audio needs to hit a broadcast or streaming loudness target.
Vocal Range & Tessiture Calculator
Score your vocal range from your lowest, highest, and comfortable singing notes: the span in semitones plus the share of that span you can sing comfortably.
