Software W&F meter.

[x-pro]

I've uploaded the first public beta version of the new real-time W&F meter by Alex Freed (many thanks for his hard work!) to the Library section on my website. Please remember - it is still a beta, so you may find some bugs and problems, however for me this program works rather well. Requires Windows XP or later and a sound card. Enjoy!

Cheers

Alex

thanks Alex, I'll give it a go. David.

Hi there,

great - thanks for the information!

However, it would be nice if frequencies other than 3kHz were possible. Not too many test records offer a 3kHz steady state test tone.

3kHz and 3.15kHz frequencies are specified for W&F measurements and only test tapes recorded with these frequencies are good for accurate speed setting and direct W&F measurements (i.e. have low residual W&f and good speed accuracy).

Good news though is that you can measure W&F reasonably well by recording 3kHz or 3.15kHz signal and playing it back 5-10 times on the same deck, than taking the average of these 5-10 measurement results. For obvious reasons you can not check the speed and speed stability this way.

Hi Alex - thanks for the info! I think that other frequencies will be useful for measurements with tachosensor or LP. At Brüel & Kjær for this used frequency multiplier of fractional coefficients multiplication.

PS there are new versions?

Thank's Alex.
