MUIC & ACOUTIC – ELECTRONIC MUIC & YNTHEI CALCULATOR
Sample Playback Pitch
A precise tool.
What is the Sample Playback Pitch & How does it work?
Electronic music synthesis often involves manipulating audio samples to achieve various effects. One common manipulation is changing the pitch of a sample, which can be done by altering its playback rate. The pitch shift is directly proportional to the rate ratio at which the sample is played.
f_{text{new}} = f_{text{original}} times text{rate ratio}
f_{text{new}} = new frequency, f_{text{original}} = original frequency, rate ratio = playback rate multiplier
The rate ratio is a dimensionless number where 1.0 means no change in pitch, values greater than 1.0 increase the pitch (higher frequencies), and values less than 1.0 decrease the pitch (lower frequencies).

Frequently Asked Questions
How does changing the playback rate affect the pitch of an audio sample?
Increasing the playback rate raises the pitch, while decreasing it lowers the pitch.
What is the formula for calculating new frequency after a pitch shift?
The new frequency (f_new) is calculated by multiplying the original frequency (f_original) by the rate ratio.
Can you explain what a rate ratio means in audio processing?
A rate ratio is a multiplier that determines how much faster or slower an audio sample plays, directly affecting its pitch.
How do I lower the pitch of an audio sample using this calculator?
To lower the pitch, use a rate ratio less than 1. For example, a rate ratio of 0.5 will halve the original frequency.
What happens if I set the rate ratio to exactly 1?
Setting the rate ratio to 1 means there is no change in pitch; the audio sample plays back at its original speed and frequency.
Can this calculator be used for both increasing and decreasing pitch?
Yes, by using a rate ratio greater than 1, you can increase the pitch; by using a rate ratio less than 1, you can decrease it.
Is there a limit to how much I can change the pitch with this method?
Theoretically, you can change the pitch as much as you want, but extreme changes may affect audio quality or clarity.
