Hi all, Any1 any idea how I could go about getting the average sample frequency of a given .WAV file loaded into Sound Forge 4.5? Thanks, Mark. |

Sound Forge 4.5 includes the Spectrum Analysis tool (one of my personal favorites!). Just open Spectrum Analysis (in the Tools menu) and select the .wav region you're interested in. This will give you the (magnitude) frequency response of the selection. Use the Settings in the Spectrum Analysis window to tweak for accuracy, but you will probably get decent (spectral) resolution with the defaults. In general, the longer the calculation takes, the more accurate it is. One last note, if you do not make a selection, then the S.A. will display the response for the N samples to the right of the cursor, where N is the FFT Size selected in the Settings. J.

Hi Mark, Sound Forge 4.5 includes the Spectrum Analysis tool (one of my personal favorites!). Just open Spectrum Analysis (in the Tools menu) and select the .wav region you're interested in. This will give you the (magnitude) frequency response of the selection. If you haven't had any DSP and want to know what's going on, try the S.A. on a few sine waves, a square wave, white noise, and an impulse. You can adjust the Settings in the Spectrum Analysis window to tweak for accuracy, but you will probably get decent enough (spectral) resolution with the defaults. In general, the longer the calculation takes, the more accurate it is. One last note, if you do not make a selection, then the S.A. will display the response for the N samples to the right of the cursor, where N is the FFT Size selected in the Settings. J.
