BPM/Pitch/Sample Conversion Calculator

Changing the tempo of a loop with pitch-shifting
To get a loop at     bpm   to be a loop at     bpm
  semitones     
This tempo transposer is useful for owners of older samplers without the time-stretch function.
Note: Akai samplers can only apply a whole percentage (i.e 98% but not 98.65%), not very precise.
This calculator provides precision to the hundredth of a semitone (about 0.04 bpm changing in average).
For decimal values of bpm, use the decimal point (i.e 96.326)
Time-stretching without shifting pitch
To get a sample at     bpm   to be a sample at     bpm  
without changing its pitch
  %     
Classic time-stretch calculator. To raise the bpm of a sample, reduce its length (time-stretch less than 100%);
to decrease the bpm, increase it's length (time-stretch more than 100%). You can enter decimal values (i.e 96.326).
To know the new tempo of a sample after pitch-shifting
For a pitch-shift of     semitones     from your sample at     bpm
  bpm     
This is the opposite of the first calculator. It provides the relation between transposition and bpm. Useful when you have, let's say,
a 90 bpm drum loop on your keyboard C3, and you want to know the bpm of this same loop played on a D3 (+ 2 semitones). You can
enter negatives and decimal values of semitones. I.e: 2.36 or -4.52 (decimal values are in hundredths of semitones).
Transposing a sample with time-stretching without changing tempo
To transpose a sample by     semitones without changing the tempo
  % first
and then apply the transposing     
Another time-stretch classic, but this time for transposing a loop. When you pitch-shift a loop of, let's say, 2 semitones,
you raise it's bpm (decrease it's length and play faster) proportionally. If you don't want the bpm to change, you first have to
expand the loop, then apply the transposition. You can enter negatives and decimal values of semitones.
Tuning a sample with time-stretching without changing tempo
To go from a (Ab3, etc..)     to a (B3, etc..)  
  % first
and then apply the transposing    
The same calculator as above, but instead of entering the semi-tones,
you can enter the note names in upper case with their octave (A#2, Db4, etc.).
Find the bpm of a loop when its length in milliseconds is known
A     measure loop     with a length of     ms
with a     beat     bpm     
This one is useful when you only know the length of a sample in milliseconds and you want to know it's bpm.
Select the number of measures, the beat, and the length in ms.
To find the bpm of a loop when its length in samples is known
A     measure loop     with a length of     samples
at a rate of     Hz     at a     beat
  bpm     
This calculator allows you to find the bpm of a part when you know it's length in samples.
Choose the number of measures, it's frequency rate, the beat, enter the samples length, and you'll have the bpm.
Find note length in samples with tempo and sampling rate
A     note     in a song at     bpm
at a rate of     Hz
  samples     
Inverse version of the previous calculator. From the bpm and a frequency rate, use this when you want to find the samples
length per measure (whole note) or for any note value. Useful to adjust loops or samples in a sampler, to find loop points,
or adjusting samples after changing their frequency rates. Note that a whole note value corresponds to one measure
(a quarter note @ 60bpm equals your selected sample rate).
Get the duration of a song based on tempo, beat, and number of measures
A song at a tempo of     bpm     with a     beat
and a number of measures of  
  minutes and     seconds,     or     seconds     
The title of this one speaks for itself. Useful in multimedia projects.
Delay and Frequency calculator
BPM:  
Delay Times and Frequencies:
Dot 1/2 note:  ms. or  hz
1/2 note:  ms. or  hz
Dot 1/4 note:  ms. or  hz
1/4 note:  ms. or  hz
1/4T note:  ms. or  hz
Dot 1/8 note:  ms. or  hz
1/8 note:  ms. or  hz
1/8T note:  ms. or  hz
1/16 note:  ms. or  hz
1/16T note:  ms. or  hz
1/32 note:  ms. or  hz
Seconds Per Measure:
  seconds
Enter the bpm of the song you're working on, and this calculator will give you the length in milliseconds of several note values.
Main use: to set your delays, pre-delays, reverb etc. It will also calculate the Hertz modulation for each note value.
Great to set your modulation effects like Tremolo, Vibrato and LFO's.
Finding the nearest note or midi value to a frequency
A     hz frequency tone
  note, or midi value of       
This represents the nearest note (name and midi value) to a frequency. Ex: 440 hz = A3 = 69.
