Using Har-Bal for audio restoration

Post by brubart »

From a recording client, I received a home-recorded analog tape made in the late 1940's. The client asked me to "make it sound good." I imported it into Har-Bal, tweaked its curve to look more like a contemporary folk recording, and recorded the EQ'd file. Then I added a steep 10 kHz lowpass filter to remove tape hiss. The customer was delighted at how much better the recording sounded.

We are happy you are finding ways to use Har-Bal most effectively. Just out of curiousity how did the spectral image look prior to you har-balizing the wave file?

Thanks

The spectrum had several big bumps around 200 Hz to 800 Hz, and rolled off pretty sharply above and below that. Har-Bal equalized the old mics, the mix, and the recording medium all at once!
