Convert Frequency / Note / Wave length

 

This tool allows conversions either from note to frequency or from frequency to note.
The reference A is adjustable.

Each frequency is associated with a wave length, which corresponds to the wave length propagated in the air. The sound speed in the air can be adjusted, because this one varies somewhat with the temperature, which makes the wave length vary, as one can see.

The note and octave can be directly entered or you can choose a reference note on a "standard" instrument in the choice list of instruments.

Please send me any comments !
You can leave a comment at the bottom of this page, no registration required.          Christophe
 
 
 
 

Frequency / Note table, with reference to some common instruments :

 

(*) Note : The wave length depends on the sound speed in air, and this one depends on lots of things including the temperature.
The adopted sound speed is 343.4 m/s, which corresponds to a temperature of  20°C at see level.
