Music & Audio
Tools for musicians and audio engineers — BPM, delay times, frequency-to-note conversion, decibel addition, and room acoustics.
BPM Tap Calculator
Calculate beats per minute from tap count and elapsed time. Essential for musicians, DJs, and music producers to determine song tempo.
Frequency to Note Calculator
Convert any frequency in Hz to the closest musical note with cents offset. Uses A4=440Hz equal temperament tuning by default.
Key Transposition Calculator
Transpose music from one key to another. Find the target key, interval name, capo position, and common transposition uses.
Decibel Addition Calculator
Calculate the combined dB level of multiple sound sources. Includes perceived loudness change and hearing safety assessment.
Delay Time Calculator
Convert BPM to delay times in milliseconds for all note values including dotted and triplet subdivisions. Essential for syncing delays, reverbs, and LFOs in music production.
Audio File Size Calculator
Estimate audio file sizes for WAV, FLAC, MP3, AAC, and OGG formats based on duration, sample rate, bit depth, and channel count.
Reverb Time (RT60) Calculator
Calculate room reverberation time using the Sabine and Eyring formulas. Determine if a room is suitable for recording, performance, or speech.
Pitch Shift Calculator
Calculate the effect of pitch shifting on frequency, tempo, and duration. Choose between linked pitch-tempo (vinyl style) or independent time-stretching.
