Is it possible to establish the Bpm of a recording in soundforge 4.5?

C&P'd from one of my previous posts you could have saved time and found by doing a search for "BPM";

Here's how to find the BPM of a file.

In Sound Forge select as exactly as possible by listening 1 measure of audio > Edit > Trim/Crop > right click on the selected audio > Properties > General tab, record the number of samples.

In Cakewalk apps. using "Audio View", (Sonar just zoom in on the audio), select as exactly as possible by listening 1 measure of audio > Right-click > Event Properties, Duration; (xxxxxxx) Samples.

Multiply the number of samples per second by the number of seconds in a minute then multiply that by the number of beats in the selection, then divide that number by the number of samples in the selected audio.

Let's use 44.1kHz (sample rate) and 4 beats per measure the equation would be;

44100 (sample rate) x 60 (seconds/minute) x 4 (Beats/measure) = 10584000 divided by (number of samples in selected audio) = BPM
