Find New BPM (BPM to Pitch)

Resulting BPM:

function calculatePitchShift() { var original = parseFloat(document.getElementById('baseBpm1').value); var target = parseFloat(document.getElementById('targetBpm').value); if (isNaN(original) || isNaN(target) || original <= 0 || target = 0 ? "+" : "") + percentChange.toFixed(2) + "% Speed Change"; } function calculateNewBpm() { var original = parseFloat(document.getElementById('baseBpm2').value); var semitones = parseFloat(document.getElementById('semitoneInput').value); if (isNaN(original) || isNaN(semitones) || original = 0 ? "+" : "") + percentChange.toFixed(2) + "% Speed Change"; }

Understanding BPM and Pitch Correction

In music production, DJing, and sound engineering, speed and pitch are intrinsically linked when using traditional resampling methods. When you speed up a track or a sample, the pitch naturally rises. Conversely, slowing it down lowers the pitch. This BPM Pitch Calculator helps you determine exactly how many semitones or cents you need to adjust a sample to match a specific tempo, or what the final BPM will be after a pitch shift.

The Mathematical Relationship

The relationship between pitch and speed follows a logarithmic scale. To increase the pitch by one octave, you must double the speed (BPM). To increase the pitch by exactly one semitone, you multiply the tempo by the 12th root of 2 (approximately 1.05946).

Our calculator uses the standard musical formulas:

• Pitch Shift (Semitones) = 12 × log₂(Target BPM / Original BPM)
• New BPM = Original BPM × 2^{(Semitones / 12)}

When to Use This Calculator

• Sample Matching: If you have a drum loop at 120 BPM but your project is 124 BPM, use the calculator to find the exact pitch shift required to make it fit without using "Time Stretching" algorithms (preserving the "classic" sampler sound).
• DJing: Calculate how much your track will be detuned when you move the pitch fader on a turntable or CDJ.
• Remixing: Determine if a vocal acapella needs to be pitched up or down to align with a new instrumental track.

Pitch and Speed Examples

Change	BPM Multiplier	Result (from 100 BPM)
+1 Semitone	1.0595	105.95 BPM
-1 Semitone	0.9439	94.39 BPM
+12 Semitones (1 Octave)	2.0000	200.00 BPM

Frequently Asked Questions

What is a "Cent"?
A cent is a unit of pitch equal to 1/100th of a semitone. There are 1,200 cents in an octave. Our calculator provides the precise cent value for fine-tuning your hardware or software samplers.

What if I don't want the pitch to change?
If you want to change the BPM without changing the pitch, you must use a "Time Stretching" or "Warping" algorithm in your DAW (like Ableton Live, FL Studio, or Logic Pro). This calculator is specifically for "Resampling" style shifts where pitch and time are linked.
