*From the PRRP website:
All remastered works are made with Cool Edit Audio Processing Software. When the source is a CD, The music is
ripped using Exact Audio Copy software. 6-Head Hi-Fi VCR is used when the source is video tape. An Onkyo cassette
deck is used for cassette tapes and monster cables connect the sources to the Sound Blaster Audigy computer sound
card. This allows 24 bit A/D conversion. The system itself is a Dell Pentium IV running at 2.8GHz.

Since the source for this concert is a radio broadcast, the sound quality is generally good to begin with. The actual
source was a CD version of the master tapes obtained from the broadcasting radio station WNEW. We would like to
thank Shaun Toole for providing his remastered source to us for this project.

Viable music signal was present up to 18,000 Hz. This is quite rare for progressive rock concerts available from the
1970’s and makes this recording quite unique. A radio transmission or microphone / patch cord buzz occurred in the
left channel off and on throughout the show and needed to be corrected. Fortunately, the buzz was specifically identified
in the frequency spectrum and was surgically attacked. This approach produced a minimal effect on the remainder of the
music. Pops and clicks occurred frequently and were manually removed. Radio announcer volume was out of proportion
to the music in some segments and needed to be adjusted. Finally, only a slight amount of noise reduction was needed
during quite segments.
