Jump to navigationJump to search

Convert the elements of x from Hertz to Cent and vice versa.

Usage
hz2cent(x {, ref {, ofs}})
log2lin(x {, ref {, ofs}})
x
a scalar, vector or matrix
ref
the reference frequency in Hz; must be a positive number (default=440)
fac
a shift value in Cent; must be a number (default=0)
Result
The result r has the same type as x and contains the converted elements of x. The following conversion algorithms are used:
  • hz2cent: ri,j = 1200 * log2(xi,j / ref) + ofs

fac * log10(xi,j / ref)

  • cent2hz: ri,j = ref * 2 ^ ((xi,j - ofs) / fac)
