Audio production calculators
Turn tempo, samples and format settings into usable numbers while keeping the creative decision in your hands.
Calculators in this section
Estimate BPM from the average gap between your taps.
Delay timeConvert BPM to straight, dotted and triplet times.
Reverb timingBuild tempo-synced pre-delay and decay spans.
Audio file sizeEstimate PCM or constant-bitrate audio data.
Samples & millisecondsConvert samples and time at a selected sample rate.
Semitone calculatorMeasure or apply a musical frequency interval.
Speaker impedanceCombine two to four speaker loads in series or parallel.
Timing that follows the grid
Tempo tools derive straight, dotted and triplet values from BPM instead of prescribing a mix setting.
Format estimates with units attached
Storage and sample conversions show the rate, duration and decimal or binary unit behind the result.
A path through the section
Most sessions start with a tempo. Tap it on the tap tempo page if you only have the track, then carry the BPM to the delay time calculator for straight, dotted and triplet note lengths, and to the reverb timing calculator for pre-delay and decay spans that land on the grid rather than across it.
The other three pages answer questions that come up while the session is running: how many samples a millisecond offset is at your sample rate, which is also how a buffer size becomes a latency figure; how far apart two frequencies are in semitones and cents; and how much disk a take will cost at a given rate, depth and channel count. The impedance page belongs to the room rather than the session, and combines speaker loads for series or parallel wiring.
Frequently asked questions
Do the timing calculators choose a creative setting?
No. They produce tempo-synced values; you still choose the division or decay that fits the material. A grid keeps a delay or a reverb tail in time with the track, but whether that is the right effect for the part is a decision no calculator can make.
Does the file-size result include metadata?
No. It estimates the audio payload. Containers, artwork, tags and variable-bitrate behavior can change the final file, and an embedded cover image alone can add a megabyte.
Where do I start if I only know the tempo by ear?
Tap it. The tap tempo page turns your taps into a BPM figure, and that number feeds straight into the delay and reverb grids on the pages next to it.
Do these tools work on a phone?
Yes, including the tap pad. Everything runs in the browser with no plug-in, no account and nothing uploaded, so a tempo tapped on a phone at rehearsal works the same as one tapped at a desk.
