Tech Notes Bertha Remaster of the 1st gen reel source

Digitally Remastered using a custom built, Dual-DAW, nicknamed Bertha, by jashley@deadacated.com. Completed December 8, 2005.

(*)Spectral analysis reveals around 10khz of Bandwidth left to the original source. It is not mentioned what the Master source is. Though, 2 analog generations is consistant with what is seen in the spectral analysis and other tests.

Spectral and Frequency analysis also reveals a highly compressed source, proabably around 50:1 Limiting. Though this achieves greater volume, it also adds distortion and harshness to the signal in the mid frequencies. The effects of the limiting were reversed to the extent possible, leaving a cleaner, less harsh recording.

The Bertha Remasters are done for no other reason than to bring greater enjoyment to my own listening experience. I share them freely and with no expectations. If others get enjoyment from them, all the better.
